Is there anyone in the area that can let me borrow there 1JZ ecu to diagnose my car, I came to the conclusion that i need to replace the ecu since there are known to go bad and since last night after the meet it's been running really funny, Poping and backfiring, coils looks good and replace the plugs with TT plus from Toyota same crap.
I hate the 1jzgte ECu i knew about the ECus going bad even before i bought the swap.
Can someone please help thanks in advance

 

Anybody with 1JZ ecu please help!!!!!

 

iv got two like i said let me know when you can make it up to the shop.

 

Thanks Matt i will try to make it today after work ,i will call around 3 pm.
I gapped the plug back to .28 didnt make any difference.

 

sorry was really bussy today see if you can make it up tomorrow.

 

Ok no problem man, i still need the ECU i barely made it to work this morning.
Stalling, backfiring,low idle , misfiring.
No more 1JZ for me lol after this one. And Thanks for all your Help Matt i got some for you!!

 

you can go lower than .028 if you suspect problems. I run around .024 with much improvement from when i ran .032.
do you have a wideband?

 

No Wideband , I am suspecting the ECU is going bad.
No check engine light,and i will do some weird stuff every other week.
I am getting some new plugs and gap them to 0.24 and see what happen at the same time I will trying a new ECU,if it's not the ECU i will let the Car sits and look for another
Thanks Ali

 

no problem, i'm sure its something you can figure out.
wideband would tell you if you are backfiring from being too rich or lean.
but there is a good chance it is your ecu if your car was running fine before so start there. have you seen this thread:

this guy rebuilds the 1jz ecus for cheap.

 

Thanks ALi i will send my ECU to get it recap,next week the car fine yesterday on my way to Matt's house it ran perfect ,i got there swap the ECu test drove it gain ran fine again ,drove 65 miles last night ran fine again, this morning i drove it to work it was running fine again.
I will just recap the ECU then if it runs fine for the whole month!!! I am Going Single.
Slow_SC3 and Cherplex got me motivated lol ,so forget those twins i will be done with them in a little bit.
Ali thanks again man

 

anytime, sounds like it should run better than ever after the re-cap.
Single is always a great idea on a TT block if you want to turn up the boost.
I still need to do my headgasket...

 

I saw a nice kit that i wanted,b ut my money is kind of funny i still need to save a few more $$$ ,It's the single kit Drewgo is selling.

When are you swapping the TT headgasket?
Let me know when !!! if you need the TT HG i can hook you up.

 

yeah, i'm in the same boat, gotta lay off the car mods for a while.
haven't set a date or anything on the headgasket job, hopefully by next summer.
If you could hook me up with the gasket i may be interested in a few weeks.
Although 9psi on 10:1 compression is fun in its own sort of way.. =)

 

U got Pmed Sir!!

 

well i have an ECU you could borrow. Ill call the shop today and ask if they could give it to me so i'll be letting you know, check ur PMs
