WOW u know your sh........... lol all of you guys in here know your stuff.

well i'm going way back about 6 years ago. a buddy who knew about cars helped me and if my memory serves me correctly we used the existing harness and ecu, he swapped one or 2 plug and we connected the harness and engine (i can't remember let me look into it and get back to you).

I can't rememeber if we used the same harness.
For sure we swapped out the exhaust manifold.

Im guessing you are using your GE MAF sensor? (the sensor right after the air filter)

If that is the case, I think that is your problem. GE and GTE MAF's are very different, not just in resistance values and voltages, but they are physically different also. GE MAF's have 7 terminals and GTE MAF's have 5. Even if you spliced a GTE MAF connector into a GE harness you would still have problems. Correct me if I'm wrong but so far you have GE MAF, GE ECU, GTE engine right?

Really need to know if you are using the GE or GTE injectors.

They also have completely different ignition systems also. GE is run by a distributor and the GTE is run by coil packs. The ignitors are not the same. Curious as to how you got this working. lol.

Yes we know this. http://toyota-supra.info/forums/showthread.php?t=7460

I was just telling him what is different that would mess with the A/F ratio.

He spliced in connectors from a GTE harness for the coil packs.

This is a challenges for you guys.

I own 2 supras. the supra that i have been asking questions about since joining has been on the 1988 auto turbo. So don't reffer back to any of my previous questions.

This question about the code 25 is on my 89 manual non turbo supra.
Let me get back to you guys on this. I don't want to give you the wrong info. This car is running good accept for the engine light.

I'm going to look into the engine and get back to you guys. cool.

til then i'll be posting questions on 88 turbo.

thanks guys.
