SR20DET Ignition Timing & TPS Adjustment
Вставка
- Опубліковано 23 лип 2024
- Today I am going to show you how to set your base ignition timing by adjusting your Cam Angle Sensor (CAS), and how to check/adjust your Throttle Position Sensor (TPS) to ensure it has the right voltage parameter.

Awesome info in this video! Totally gonna check my timing this weekend.
Good shit.. been looking for vids like this for years.. simple tools and simple explanation
Best video description on timing and TPS adjustment. Timed it last night using the steps provided here, testing TPS today. You're the man, man!
Wow, thank you so much for being so well-spoken and easy to follow. This is exactly what I needed to know while just doing the final tweaks on my s13 Silvia. I appreciate your time. -Thanks again!
Glad you found it helpful. That’s what it’s all about. Cheers!
If that is a OEM coilpack harness, there should be a loop in the back of it for the timing pickup. However from my personal experience, you should use a old spark plug wire to make a bridge between the coilpack and spark plug for the pickup to get a more accurate reading (FSM even says to). Sometimes there is interference with the other coilpacks/wiring to the #1 cylinder and the timing light would be sporadic.
1) warm up car to normal operating temp
2) turn off car, unplug TPS
3) start car, rev 3 times to go to timing mode
4) adjust timing
5) check idle speed, adj if necessary
6) turn off car, replug TPS
7) start car and check
this with a bridge from #1 coilpack to spark plug is the only way I found to accurately adjust the timing on my s14 SR
Hey mate thanks, 1 question tho, do I have to rev it 3 times to a specific amount of revs or just any amount of revs 3 times?
@@hunterhaley1343 I believe FSM says to 2000, I usually rev it 3 times to 2000 after unplugging the TPS starting and the idle seems to be stable to set timing.
thank you very much for the good explanation, may I ask what FSM stands for? EDIT: FSM menas factory service manual.
@@mxklkarmonkey970 Yes, Factory Service Manual
REALLY HELPFULL! I just got my s13 with SR and i want to be sure that its on right timing. very good and simple explanation! thank you!
As everyone else in the comments, thanks for a really well explained and easy to follow video buddy!
Good video brother! So many people are afraid of timing. Think it's way over complicated when it's really fool proof! Keep it up!
Hey brother when u gonna post more hardbody videos? Oh I'm waiting on those stickers lol
Hey buddy. Currently posting a video and towards the end I gave u a shout out. I dont have many followers but hope it helps.
Great video, very informative and easy to watch.
I appreciate that. Thank you for watching. Sorry if the quality is low right now. It takes awhile for the 4K resolution to process on UA-cam for a video this long.
Easy and great video man! Thanks 🙏🏻
ghazi debiche Thanks!
Woah im impressed by that commentary. A GREAT video. thumbs up! :)
Great video, I'll have to check my s13 when I get back to Japan
Great! Very nice explanation. Thank you from Russia:)
Very helpful video, adjusted both this weekend and everything went smooth and easy just as you explained in the video, thank you!
enjoyed a lot!! thanks for the tip
you're a G man. very good informative video
Super helpful! Thank you
Well explained 🙏 ❤
Good informative videos! Simple and clean content! Love it man!
Can you give info about swapping out ka24de for sr20det? And the things you need to do the swap. Thanks!
Great content.. Tq
Bruh that was a helpful ass video ty
Sweet! You’re welcome.
Awesome video! I have a 2000 Infiniti g20 it has a sr20 engine in it. Do you think this video is apical to my engine?
Thanks you
Thank you!
Samurai John You’re welcome!
Can I connect my positive clamp to the alternator power wire? Should be the same right?
Do you avoid adjusting the throttle cam/idle screw to effect the tps voltage? My voltage was high and the cam was opening the throttle. Haven’t been able to find it in the FSM and appreciate any info.
Awesome video! Correct me if I’m wrong, but I thought that you need to use an ignition cable between the first coil pack and it’s spark plug like a bridge in order to get an accurate reading since the SR20 doesn’t use a distributor/ignition cable style of ignition system? In other words you would clamp the timing light to an ignition wire instead of a coil pack signal?
Kevin Martinez nope, nothing fancy. You just clamp that bad boy over your coil pack wires leading to number one cylinder. It works just fine.
Yes use an old spark plug cable as a bridge between coilpack and the spark plug to get a most accurate reading. If you don't do that, there is supposed to be a small wire in a loop on the back of the OEM coil pack harness specifically for timing but I always found using a old spark plug wire as a bridge to be the best. S14 SR FSM has the procedure
Great video man! I was wondering what your issue in the end of the video was my car misfires similarly to that but I’ve changed the plugs injectors and coil packs
Injector seals ended up being torn on two cylinders. I was in a hurry and didn’t lube them well before installing, so they pinch tore. Ordered new seal o-rings, lubed them up a little with Vasoline, then installed. Problem solved.
@@Inner_Sanctum awesome thanks for the reply! I didn’t lube mine either but i took them out and checked and they were okay so i lubed them up but maybe they tore a little bit
@@koukikev8813 yeah, mine looked okay too. However, my intake runner was filling up with fuel. I would turn the car on, let it run for awhile then shut it off. Pulled off the upper intake manifold and the lower runner was pooling with fuel. I knew immediately at that point.
yooo is that nomuken's signature??? sick!!!
It is! Haha Super nice guy.
Set closed to .450 but wide open reads 3.80 is this an issue?
Can we change sr20 come with distributor change to coil on plug ?
Could u do a vidoes on instaling a cam angle sensor on a sr20de fwd engine need to no thank
So I should out my engine to 15 instead of 0 degress , . It is a unknown motor . Trying to put a base map on but struggles to idles nicely n rev
When I checked my tps at wot it only has 3.2 volts instead of the 4volts. How do I get it to 4 volts? It’s making it run lean at wot
so what is the timing gun actually for??
Does it get messy changing your oil filter at that location? I know it’s easy access but I was just wondering if gets everywhere having it upright
Nope, it drains down before I ever pull the filter off. If anything, it’s cleaner/easier than having it on the bottom where the filter holds the oil and it gets everywhere.
@@Inner_Sanctum nice! awesome man! Thanks 👍🏽
So if I set my tps to .44 closed and it only goes to 3.9 wot is my tps bad?
For people who are trying to time their engine just read the FSM
I have the same multimeter as his but I don’t get .45 volts mine reads 4.5 even on 12v setting
This shit pisses me off I can’t do my tps sensor because of this even on WOT it’s reading like 9.xx volts
Ok. Now how do you set the timing! You showed us how to check it but if your timing is off, how do you correct it?!
I literally explained that in the video... you adjust it by rotating the CAS forward or back to advance or retard the timing.
How does this Sr20 have coil packs I thought they were all distributor engines
T_money_ THIRD DET engines use coil packs. DE [NA] engines use distributors.
@@Inner_Sanctum thanks I been trying to figure that out all year. All the turbo Sr20 with spark plug wires got aftermarket turbos.
@@Inner_Sanctum I wanted an Sr20det for a conversion into a fwd car but all the Sr20det seem to be rear wheel drive setups. The Sr20de are front wheel drive setups but they use distributors and spark plug wires which I hate.
What ended up being your missfire?
Torn injector o-rings on 3 and 4 due to a hasty install. Bought all new o-rings, used a little petroleum jelly and gently pressed the rail in. Problem solved.
@@Inner_Sanctum Oh okay, good catch!
@@Inner_Sanctum By the way, did you unplug you're TPS? My timing light is all over the damn place...
@@jdmking4776 Yep. You need to unplug that badboy! Make sure the car is also at operating temperature or else your IACV is going to do funky things.
99% of running issues come from peoples lack of patience with this basic yet important step.
