How To Chip an OBD1 Honda ECU
Вставка
- Опубліковано 14 жов 2024
- Hey, Friends! Happy Holidays!! I hope you're all doing well! Follow along as I take a trip down memory lane, to the days where my basement was an ECU chipping factory... Today I'll be chipping my P72 ECU and installing a Bluetooth module in hopes of being able to run a tablet as a digital race dash! I've come across many DIY's in my day for this exact process and I think I did a pretty good job in simplifying the process for everyone to learn!

This is priceless content, bro. Makes me want to swap the daily just to have a reason to try some ECU work at home. Thank you for posting this, and can't wait for the follow-up with chip burning!
Thanks for watching! Swap the daily! lol just kidding, don't do it. You'll have to buy another one...
@@bvspeed I thought it was funny when you said you were shipping so many ECU's here to Ireland too.
I have a Hondata bought for my H22 Prelude but I haven't gotten around to firing it in yet. It's not something I'm gonna try to do myself though!
I was a Tech for decades, I have to say: Nice work! Also you have a knack for teaching.
Thank you sir! Very kind of you, thanks for watching
amzing camera angles. i was able to learn alot about soldering technique and actually do my own ecu. thanks
No problem! Thanks for watching, glad I could help!
Brilliant video. A great insight into what goes into chipping an ECU.
Thanks for watching!
Super helpful , about to do a p13 for a mate . This was very helpful in building my confidence up
Awesome! Glad I could help.
I don't have a knock sensor on my D15z6 engine ..I plan to put an obd1 ECU and chip it ,but only as stock and for a day to day drive ...I just need dataloging and ..is exactly what I want ..what I saw on your video
Awesome content, bro! Merry Christmas and Happy New Year!
Thank you so much! Happy holidays!
I would love one of this for my ek
That’s why I made the How To! So you can do it too!
very good video, i dont understand why you don't have millions of subscribers :D
😅please tell everyone haha
Nice video. Can you confirm it's not necessary to worry about static (earthing bracelet or gloves) when replacing any chips in ECU? Thanks
Although I had an 88 prelude si about 22 years ago I am no longer a Honda guy. I found your video because I am currently working on a 88 Volvo with a lh 2.2 jetronics ecu for the fuel injection.
I read in a forum that older Hondas also got this lh 2.2 system and that as far as chipping, tuning, and data logging the Honda crowd has done the most with these old pre obd ecu's
I am aware that these boards are obd1 and that you may not be able to help but this is my first go at tuning an ecu because All my other toys don't have them.
I have spent days and days online on diff Volvo forums without much progress until I saw a guys post pointing me in the Honda direction. Your mods are exactley what I'm looking to do so if you any inf or know anybody with a pre obd stock ecu that's tuned with data logging capabilities a shove in the right direction would be greatly appreciated!
Anyways great videos. Thanks
I'm not quite sure when it comes to the Volvo brand. I'd recommend visiting Moates.net and getting in touch with those guys there. They're legends when it comes to this stuff so I'm sure they can at least point you in the right direction.
Thank you for this upload, it’s going to help me with my ecu modifying. hopefully your channel gets big 🤙🏽🙏🏽
No problem! Glad I could help. Thank you for the kind words!
Great video, thanks for the knowledge sharing, Pls share link to second part, many thx
This is fantastic! Do you still write chips for customers?
Unfortunately I do not. Check out my boy, Nomisind on IG! He’s much more skilled than me!
Wow good job bro ❤
Tuning videos?
Part2 ?😊
Thank you! Haha, not really sure if there will be another.
Really great video bro, keep up the good work
Thank you! I appreciate it!
Bro! Love this content! Thank you for the tutorial!
Glad you enjoy it! Thanks for watching!
Awesome job! Can't wait till the next video. Very good explanation
I appreciate it, thank you!
Dude awesome vid and it’s one of a kind keep up the amazing work.
Thank you! It means a lot!
Hi! Where do you buy the chip kit? Can you provide a website.. it s look you are doing good job. Thank you for the video
HAMotorsports is a good place to go for ecu parts! Thanks for watching!
@@bvspeed thank you.. can you program a chip for b16A swap on canadian civic sir 00
Hi, Im just currious if you have any insight on the location of the IACV components?
I have a code 14 on my chipped p06.
I tested my IACV, it works when power is applied and i have 2 spares.
I have 12v at the IACV connector and the ground signal wire has continuity from the ECU pin A9 to the IACV connector.
I have my IACV hooked up to a toggle switch for now haha.
Great video by the way!
To a toggle switch!? Haha nice! I don’t know specifically where the IACV circuitry is located, but I’d imagine you can open up the ECU an basically trace where the wire goes into the ECU and follow the path to the components.
@@bvspeed Ya haha! I just wired it to the overhead passenger side map light switch on my 1990 CB6 "2.0si Exclusive Coupe".
Thanks for the advice!
First of all, thank you very much for sharing your knowledge and priceless experience with us viewers. I wanted to install a Bluetooth chip for my P27 ecu so I can be able to communicate with the app via hondash. Where would you recommend buying that CN2 Bluetooth module? Thanks!
Thanks for watching and for the kind words! Take a look at HAMotorsports. They should have them available.
you are really a guru man
🙌🏼
good job bro ! please could you give me the speed socket's link to buy it ? thanks from France
HAMotorsports in the US. Or else I’m sure you can find it on eBay. Search for a 28pin ZIF socket.
@bvspeed absolutely brilliant work. I love and appreciate you work. Are you currently offering ECU services?? Thanks!
Thank you so much for the kind words! Currently I’m not offering any services, but I can recommend a few!
HAMotorsports
Phearable
Moates
Nice work!!!
Thank you!
Could I use this vid as a direct guide to chipping a p28 or will it be different?
Same exact way!
Such a good and detailed vid great job. If my p72 is chipped and I want to reuse it as a virgin ecu do I need to unsolder all the parts or just some?
Thank you! All you would have to do is cut the J1 jumper and the ECU will revert back to OE. Think of the J1 jumper as a switch from OE to auxiliary tune.
@@bvspeed Thanks for the information.
No problem!
Awesome. very detailed video. from where did you bought Bluetooth module😀
Thanks! I got the BT module from HA Motorsports.
Very nice and neat work bro, amazing 🍾🍾🍾
Thank you, I appreciate it!
Thanks for the great video very informative… have you chipped a pm6 OBD0 ecu?
Thank you! I have not done any OBD0 ECU’s.
I appreciate your videos they help me a lot but I’m still a bit confused I got a PO six and I put her on my Internet f22b1 I checked the computer what can I do to make sure you’re running the proper way
This is just the chipping process. To get it to run properly, you’ll need to have the car tuned by a Tuner.
bro thankyouu, i am seriously considering this on myintegra but i’m just a bit nervous to start since it’s my first and only car
Hey! At one point or another you’re going to have to start somewhere! I’d recommend to grab a junk ECU and just practice until you’re comfortable with performing the work on your ECU. I hope you found the video useful! Thanks for watching!
bvspeed super useful
Thanks you the good info, where can I buy all those parts? Including Bluetooth? Chip socket , etc...
I got all of my stuff from HAMotorsports.com
@@bvspeed is there a way to put 2 maps and switch between them? Let's say eco mode and normal mode
Look into this.
www.hamotorsports.com/products/2timer
What the purpose for adding those chip my friend?is it for tuning?
Yup! It’s to allow the engine to be tuned.
what kind of soldering wire did you use? and at what heat for the solder itself?
I use a lead-free rosin core solder. I like to use a small diameter, that way I have more control of how much I’m adding into a joint. I forget the exact temp at which the solder melts, but I solder at just above that to keep board temps down as much as possible. If I have stubborn joints, I’ll ramp up the temperature momentarily.
Hey!
I’m trying to gather information because i might want to set up a bussiness here in the Netherlands similar to the one you had. Can you chip any obd1 ecu or only specific kinds? Thanks in advance!
Dani
this is the shit right here. Thanks a million bro. Coffee on me hahaha
Hahah no problem! Thanks for watching! 🙌🏼
hey i am from jamaica with a 1995 accord my ecu is giving problem. i want to chip it where can i oreder the parts ?
this vidoe is amazing bro
You can order parts from:

Thanks for watching!
👍
You or can you recommend any shop I can get my blown capacitor p06 replace?
Got a few recommendations!

Excellent work
Thank you!
Hi, i accidentally shorted 2 pins on the 74HC737. I noticed only after a failed test. I removed the bridge and retested, but it doesn't go. Did I fry the HC737?
Sir next video how to test i.c and capacitor on multitester im ricky in the philipines nice video sir
Thank you!
Where you get parts from?
such as
socketing kit
Adding VTEC
Capacitors

That's very interesting 😀
Indeed!
Thanks bro I have an EK 4 door with a GSR head and b20 block with ls trans with skunk 2 manifold and a GSR throttle body with a AEM fuel pump I am running a virgin p72 ECU it doesn’t run the way I would like it to what would make my car run atleast street tuned . New to tuning and chipping ECU . Thanks in advance
Yup! Just sounds like you need a good tune. This tutorial basically works for anything like Hondata or Moates Demon units as well. It’s all the same process.
@@bvspeed thanks I just chipped my ECU
Thanks for sharing
Thanks for watching!
Your videos are so satisfying!! Would love to learn to do this on my ECU but im afraid of making a mistake
Thanks for watching! Eventually you’re just going to have to do it! Pick up a garbage ECU and just practice!
@@bvspeed well my ecu went bad. Took it apart and found a few bad capacitor. I have a p05 from a 92 Civic CX. Can a S300 be installed along with the bad components?
Yes you can chip the P05, but it’s only designed to run a 1-wire O2 sensor. It’ll have to be converted to a 4-wire O2 and also converted to VTEC depending on your power plant.
@@bvspeed thank you brother for your response. Future plan would be b swap, so definitely would like to convert it to VTEC. Gonna try and attempt to do it my self. Mind asking where do you purchase your repair kit as well as the conversion kit?
@@m.hernandez91 www.HAMotorsports.com
Can you do one more...for my small country antigua 🇦🇬plz
Maybe towards the end of the year when things slow down?
what about ic 17? if heated the car can immediately run. if it hasn't been turned on for a long time, the car is difficult to start. *ecu p27
So do you still do this on the side, because I’ve been looking for a p72 ecu for my gsr swap on my 00 ek can you help a brother out. So i have a obd2B jumper to obd1 but no luck on finding a p72 I’m trying to get my car To pass A state ref. Can you help me?
I currently don’t do this anymore. It was a ton of work without not much return, especially with how scarce the market is getting with these ECU’s getting older and older.
I do have recommendations though:
FFsquad.net (go to FF Chips section)
^ that’s Jason Katman, legend in Honda scene
HAMotorsports.com
Phearable.net
Moates.net
Can you link the part2!!! I need more info😢
Haha sorry, not really sure if I’ll be doing a part 2 anytime soon. What are you looking at trying to do?
Hello thanks for the video ! I have a MiniVTEC B16a with JDM B16A. I am running OBD0 with PW0 ECU all stock. But I have the JDM ECU with speed limiter and 2 O2 sensor which I would only use 1 with header. I want to keep my original ECU and make these changes. Is it possible?
Thanks for your feedback
I’m not quite sure if I understand what you’re asking. Are you saying you want to still use your PW0, but eliminate the secondary O2 and the speed limiter from it?
@@bvspeed yes exactly !
Epic
Great content ! 🤟🏽
Thank you so much!
Hay mate that’s impressive, nice piece of work, actually what’s happening with this? is that only for the wireless monitor?? Could you explain in simple way? Subbed ❤️
Thank you! Yes, so far it’s just to run a dash. I guess we’ll see how reliable it is and how bad the latency is, haha!
@@bvspeed , at the risk of sounding stupid or clueless. I’m not trying to be a copy cat but I guess I’m bein a copy cat. As long as you don’t mind. Anyhow wanting to do same deal with dash cause poor Lol. I’m running a Hondata Kpro 4 w/ k20 . It already has data logging enabled as you probably already know w/ virtual REAL TIME gauges . So basically your running the tablet just as you would a laptop? Like when your tuning? Thanks in advance. Subbed a few weeks ago. The time attack hatch vid was AMAZING!!! 🔥🔥👍🏻👍🏻👍🏻
Hey! No worries, technically we're all copy cats. Plenty of people have done this before us! The main goal is to have the tablet replace my gauge cluster completely, simply because I don't have a dash and the stock gauge cluster zip tied above the steering column is hideous lol. The only thing I'm trying to get is the "real-time" gauges, not really using it for the tuning aspect. Thanks for watching the videos! I'm looking forward to filming a part two of Mark's time attack Civic! Who knows, maybe I'll get to drive it!
@@bvspeed , thanks yeah I understand your plan now. Actually I just want the gauges too. Not for tuning. I DID research some before asking you. Do you know if the Hondata Kpro 4 is capable AS IS to run the real time gauges features the kpro has on a tablet . For poor mans gauge cluster? Thanks in advance
@@notone4029 KPro V4 has the Bluetooth option so it sounds like you’re already set. You just need to enable it in the software.

Dope love this ❤
Thank you!
Hey brother upgrade my ecu on my 01 Honda CR-V automatic AWD B20Z2 engine but I can't find anything. Do you have any suggestions?
Hey bro, Do you do ecu work on the side? I got a p28 hondata s300, solid CEL no fuel prime. Just want to change out capcitors
Hey! I currently don’t work on them anymore. Capacitors will be the easiest place to start. If that doesn’t solve it, try going through this post to see if it can help!

hi where can i buy all the parts el. parts that you desolder
Most of my stuff is from Xytronics.
@@bvspeed oh I thought it was a set i can buy
I bought the hondata s300v3.
Haven't found an ecu yet
I just need all the small parts you soldered out. Hats due a list and number for me.
I think of all the other videos yours is the best done
I got all of the components from HAMotorsports.com. You also try Moates, Xenocron, or Phearable.
Thanks for watching!
@@bvspeed ok thanks i wiöl by this part.
I subscribe your chanel.
This is my crx: ua-cam.com/video/sz8P5uEwxsk/v-deo.html
Hello. How can I send you a photo? I have questions about the control unit
Sure! Feel free to DM me on IG. @bv.speed
Where did you purchase your chip kit
HAMotorsports.com
What if I want you to supply me with some ecu can you do it?
Would an Acura Legend MT ECU need any software burnt to it after chip installation ? if so can you provide me with that .? Thanks
Anything that gets chipped would need a map uploaded to it.
I have a stock d17a2 and I'm wondering how to get acces to data logging and upload the Hondata tune to the stock ecu?
That might be tough. There isn’t much support for the 7th gen chassis.
@@bvspeed yeah, quite disappointing
podrias hacer uno para una p13?
Thank you
You’re welcome!
Hey can you check out my ecu and I have another one that got fried could that be fixed?
Check out my boy, Nomisind on IG! He’s much more skilled than me!
Where can I get that kit you installed?
You can get them from HAMotorsports.com.
Can I get link for the product's use in this video bro

Hi , ever you chipped P27 ??
I dont believe I have.
Hi sir .Last week l was chiped my ecu (p29 jdm) .My friend write a chip for me and we install it but my car is in limp mode .l was remove r52 rp 17 and put a wire for rp 18.how can l solve my problem .My chip is working same jdm p29 civic si.l think chip burning is true.Could you help me:(
How can we text if there is a bad fuel problem on the ecu pl
can you burn me a 1.8 integra type r map for my 95 civic swap
Be nice if people would start posting videos of actually tuning ignition and fuel maps
Will this work for P0h by chance?
Any insight would be eternally grateful so I don’t have to but a s3000
I found my answer and the answer is no
I believe it has something to do with the obd2 not having the capability to data log or rewrite the program but the obd1 has the ability to to do so because eprom is somewhere is that’s installs it on the obd1
Yeah, the OBD2 stuff around 96-01 didn’t have the best support. I think Hondata had a little bit of support for it, but it wasn’t nearly as good as OBD1 stuff.
@@bvspeed gotcha
So one last question sorry 😓
I found a p28-a01 and some other version p28-a02 that I believe are obd1
My question is would either be able to be chipped using this process in the video and the a program burned via a tool using Neptune or something cutting out the need for hondata or a s3000 tool?
I might be able to find a torrent version of either program but before I drive 5 hours to get a ecu that has a coolant cel code 6 and attempt to fix it
I was wondering if it’s even possible
What Temp settings are you using?
Temp settings for the soldering station?
What about the p75-A51 world it be compatible putting it in a 97 Honda with a b20b JDM Engine
Yes, but you’ll need an OBD2-A to OBD1 ECU adapter harness.
hi, is it the same with p08 ecu ?
For a majority of the it, yes.
@@bvspeed thank you!!
Is it the same for the P28 ?
Yup!
I have some tech questions say I bought an ecu and found out when the weather is cold the fuel pump doesn't prime I think because the prior owner might have hooked up the iacv plug in the iat and vise versa do you know what component I would need to replace?
When the IACV and IAT mix-up occurs, the IAT sensor or wiring usually gets damaged and/or the circuitry in the ECU for that sensor gets fried. The reason for that is because engine sensors (ie: IAT) are designed to run on 5V whereas the IACV is a solenoid that runs on battery power (12V). Ohms Law tells us that with an increase in voltage, comes an increase in amperage. Which unfortunately equals fried parts...
The problem with the fuel pump not priming sounds like a separate issue. Evidence that it happens in the cold leads me to believe that the main/fuel pump relay has failed. Solder joints in the relay tend to crack over time. When it gets cold, a solder joint that has cracked will "shrink", creating an open in the circuit. I would suggest trying a new main relay or if you're feeling adventurous, open up your main relay to inspect the solder joints.
@@bvspeed It's not the main relay or any relay for that matter I've already check and swapped the relay even though the solder joints were still good and that wasn't the problem at all I've found that when the issue occurs I can literally warm up the ecu with a heater and it will start right up the reason I thought it could possibly be that the wires were swapped is cause I know and have seen Q31 be burned up as a result of the purge valve and iat being plugged in the others spot and I thought Q31 was also the transistor for the fuel pump with C14 and C15 being the caps
@James Got it. What does the ECU board currently look like? Any obvious signs of damage?
@@bvspeed I really appreciate the reply bro after I replaced all of the capacitors the problem would only happen in more severe cold conditions it's weird I've heard of some people grounding the fuel pump output on the harness side so the pump primes everytime like basically bypassing it I guess
@@bvspeed The C14 does look a little weathered on the board where the capacitor originally leaked and I replaced it but like I said it's weird cause you wouldn't know anything was wrong with it how it starts up perfectly normal unless it's blistering cold outside that's the only reason I considered it could possibly be something else
Your my new best friend 🫡
Haha thanks for watching!
👍 #500
🤟🏼
i have a p28 ecu with vtec issues where would i go in the ecu to replace
You got any p28 for a manual forsale?
I do not.
My hands aren't steady enough for this. So it's a good thing stock power is enough for me and data logging isn't needed. lol
Well it’s here when the time comes! 😆
@@bvspeed I wish I could say the same - but still waiting on a b16a2 swap to leave HMO. :(
Is chipping an obd2 ecu the same process
I haven’t chipped an OBD2 ECU, so I can’t say.
Can u make me one i have a 2001 CRV all wheel
Hey! Unfortunately I don’t offer any services or sales anymore. You can however, check out guys like HA Motorsports and Xenocron. They’ll for sure be able to hook you up! Thanks for watching!
Ok thanks
ay bro can you show anything a but ktuner
Sorry, unfortunately I don't have any experience with K Tuner.
How much you charge for this job
I currently don’t offer any chipping services, sorry!
How much life will be left in my civic 2000 ecu?
There’s no telling how long it’ll last.
@@bvspeed some people say that if everything is working fine so no issue will be with capacitor
@@skhurshid248 All it is, is preventative maintenance. You either do it for that peace of mind or you don’t. Entirely up to you.
@@bvspeed thanks for considering me to reply
BTW, your video was awesome. Learned many things. I am from Pakistan and here we cannot even imagine the quality of work you have performed. Is there any video on wiring of civic ?
I posted a few videos of playing with some wiring. Just look through the videos and you’ll find them. Thanks!
P1g ecu its chippeable
mmmmm
Do u have facebook or whatsapp number? My p08 chip are burn..can u help?
