THROTTLE BODY SWAP NO CEL!!!!

[tk-421]

Sorry, I meant to say to leave the 1NZ chip on the 1ZZ TB. I made the swap and I haven't had any issues so far, other that a high idle when cold starting the car.

On the other hand, I've heard from some people that didn't need to swap the chip at all (1zz chip on 1zz TB). I have a theory that the issue is directly related to the TB serial number, but I can't say for sure. I tried compiling a list of serials a few months ago, but it didn't catch on.

Thanks for the advice,tk-421...

With your 1NZ chip on the 1ZZ TB, did you experience any jerking (around 1300rpm) while you were driving?

Did you adjust your idling screw? How many turns did you adjust? Anti-clockwise?

Thanks in advance, tk-421...

The bigger TB will increase your overall throttle response. There's a bit on an adjustment required on your part (basically, one needs to be less hard on the pedal). Although to be honest, the throttle controller that I have installed makes that effect much more apparent.

I can't remember right now, but I believe it was more to the right (CW) than the left (CCW), but it really should depend on your particular installation. You can adjust it while the engine is on, but don't trust it too much... The ECU will also try to auto-adjust over the next few days. If you don't feel that it's perfect you can always try adjusting it further. Just be careful not to strip the screw!
