I've been trying to get a ecu for my 95 Toyota T100 for a few months now. After watching this video I finally can get it back on the road again thanks a ton!
Here is some advice from an experienced professional ("Huge Intruder"), he provided after watching the video I thought you guys could get some help from: 1. Flux is used as a anti-oxidation agent when forming solder joints. It makes no sense to use flux when de-soldering a joint. In fact, most solder is flux rosin core, which already contains the necessary flux, and additional flux is not needed even when forming a solder joint. 2. It’s not necessary to tin the leads of the components in advance. This can actually make it difficult to insert the leads into the board if you apply too much solder in advance. No such tinning is used in the automated wave flow soldering manufacturing of boards. 3. You wore gloves in an effort to protect the board, but you actually probably risked doing more damage to the components on the board by not practicing proper electro-static discharge (ESD) procedures. 4. The “stuff” you mentioned that leaked on the board is called electrolyte and eats away at the board and the electrical traces on the board.
About to do same thing on same exact ecu. I have some experience with solder. Doing fpv drone flight boards but I in no way a pro. And I hope this time I get this right on my ecu. Thank you for those tips that helps. I never have used flux nor do I own any I just de solder and solder back.
This was awesome man, I’m about to inspect my aem series 1 ecm because I’m pretty sure my “bucking” issue is caused by some leaky caps. I’m not bad at soldering etc but after watching your video I’m confident I can do it A1. You’re the real mvp.
thank you very much !! very informative, good suggestion to find an old radio and practice first; this video has given me the confidence to do the ECU myself (and not pay Cardone $500 to do the same work)
Yes! Definitely practice first and make sure not to leave the soldering iron on for too long. Make sure you also know how to use flux. Flux was a life saver for me when doing this job. When I used flux correctly, the capacitors came off super easy. The main thing to do is to not overheat the board or "pads" where the capacitors attach to. Let me know if you have any questions.
May I ask how do you test to fiind a faulty park on board? You show that it's easy if it's leaking. I'm getting a easy you in the next couple weeks that needs to be fixed and i'm going to try and fix it and i'm trying to gain information on how did diagnose the ECU.
@@John-j8g so my Supra was having random issues, one day it just turned off on me. A few weeks later it just wouldn’t start again. I spent some time looking into it till I finally decided to take the ecu and look at it. I am glad I did. That was my problem.
@@DriversTherapy I'm buying a 1993 Ducati 888 the ECU is bad in it. I'm looking to fix it so the bike has all matching numbers. I can do the soldering just I'm trying to learn how to check to find the problem with it. I wish I took wiring in hi school. I would be much better off if I did. I pick up the bike next month. I want to be ready to do this project.
Heyyy, late comment I know but just a tip. A lot of the time they use lead free solder on these pcbs which is definitely more difficult to desolder. Trick is to actually add some tin/lead solder to the joint and then it will mix with the lead free and be MUCH easier to work with.
@@DriversTherapy Yeah it was a good video. I have to tackle caps on my 98 avalon and I'm always looking for different techniques. Another thing I find helpful is using 63/37 tin/lead solder. It's eutectic which means it melts at the same temp it solidifies, so there is no "in between" state to wait for and you get less cold joints if you aren't holding the component waiting for it to solidify. I know I don't have the steadiest hand anymore haha. Thanks for the vid man.
Would you be willing to replace my capacitors, I am too scared to solder, I have a set of capacitors for my ecu but I am overwhelmed- I have extra capacitors that I can send in case any break - I got them from digi-parts. 😅- I can pay you for the work - please, yeah I am desperate in finding help/trust
Hi, this website "DigiKey" is a great place to buy capacitors. www.digikey.com/?DigiKey&EN_Brand_Digi-Key&DigiKey&gclid=CjwKCAjwpayjBhAnEiwA-7ena2M7NlgD8DpvDnVNUsOZ_ceNTtw-03kFMcLMOz_Gw1er8XVLxVyubxoCLckQAvD_BwE
Also, you can find a generic pack on eBay. They will work but not the same quality as DigiKey. Let me know if you need any more help.

I found one eBay but it’s $1900 isn’t that too much ? Don’t you think I’m better off going stand-alone ? I have a stock 2jzge on a mk4 Supra . Im planning on going single turbo eventually maybe at the end of the year.
@@ivan2jzbunny open it up, send me some pictures and I can help guide you. If it’s not too and any electronics shop can replace a capacitor. Don’t get suckered into these shops that say they have done a lot. Some bad actors in that space.
Hi mate I have one of the square black 5 pin parts possibly a capasitor leaking causing a intermittent no start. Have you ever had any issues with these parts before ?
Thanks for the good job. Could you answer my questions? 1. What if I replace it with another brand but same voltage and capacitance? 2. What if I change it using the same brand but higher voltage but same farad? 3. What if I replace it using the same brand with higher farad but same voltage? Regards
Hi, I am only going to recommend that you use capacitors with the manufacture's original specifications. I don't know why someone would deviate since the failure is not due to design, tolerances, or resistance, but simply due to age.
I had the same issue on my audi. Unfortunately, the leak was spreading to the circuit and caused it to burnt and melt. Had to replace the whole unit, which costs me alot!
Hi please can guide me how I know which capacitor I need for my LS430 2005 also can I change the capacitor if it’s look good dose it make difference with a new cap Thanks
@@DriversTherapy no I’m sorry I’m planning to after buying rapier kit and capacitors to be ready to go that’s why I’m asking could you help me with capacitors types

@@DriversTherapy do I have to buy a heat gun or can a blow dryer get the housing off?
@@bentleylagerlive a blow dryer can work. Just take your time and pry around in different locations.
learned something new today .... love to see you about to hit 3k
Nice! And thank you for love!

Is it weird that your voice is therapeutic 😌
❤️❤️❤️
Thank you for making a great viedo. I have a ECU from an old motorcycle the ECU is bad and i want to fix it my self. Im here getting some training.
Glad it helped. Let me know if you need any additional help with questions or advice.

@@LargeAlbatross awesome! I will look at the type of solder ratio next time. Thank you again for the advice and for watching the video.
Good job! I did the same for an LS400 ECU I used In an engine swap.
It was really easy and cheap
Thank you! Glad it worked out for you too. LS400 is a plush ride!!!

@@ivan2jzbunny way too much. I paid 400. You can have yours fixed or you can ask on the forums or Facebook page if anyone is selling one.

@@DriversTherapy okay. Thak you
Hi mate, do you know the cause of the leak cap?
I had the same issue on my audi. Unfortunately, the leak was spreading to the circuit and caused it to burnt and melt. Had to replace the whole unit, which costs me alot!
the caps in the 90s were built like that. So sooner or later all 90s caps will mostly leak.
I'm curious. Did you ever put this ECU back in your Supra and test it in the car? If so, how did it go compared to the new ECU that you purchased?
I sold this one and heard no issues from the new owner
400 is way to high IMO for old THT Boards, I used 335 on mine. Good tutorial video
Great recommendation. I will lower my settings. Thanks for watching. 😀

Your welcome. Thank you for leaving a comment. :D
Just get the soldering iron touch both leads and yank that sucker out. 😁
Nice! One of mine was stuck but with some flux it broke free. Thanks for watching. Let me know if you have any questions.
👍🏻

Took the whole video to pull out two capacitors? 😂
Why are you watching chump?
It took me a long time also to replace 4 capacitors toyotas welds I have a crank start thn dies symthoms after I replace caps it still the same
