I am in need of an original prom chip for an 89 Iroc-Z 305TPI automatic. My second option is to have my current prom chip flashed back to the original settings. (my son changed the lockup converter setting and we no longer have the equipment to flash it back)

 

What type of flashing did you all do? I have a stock one I am using now but would need yours, if it works correctly, to replace the one I would give you.

As far as I know the only thing changed is when the converter locks up. I drive the car once or twice a week. I drove it to work today.

 

Oh. Well let me keep an eye peeled. Not too sure I want the reflash for just the lock-up. Heck, my car does not even lock up for some unknown reason. I guess maybe I have the same thing?

 

i have one from an 88 iroc 305 TPI auto... if your interested let me know.

 

I'm interested if the price is right. Did the 88 have a cold start injector (9th injector) ?

 

i sent you a pm.

 

You don't want the one for an 88.

 

I thought there was a difference between the 88 and 89. Why does the stinking MS .net login for Hotmail keep popping up when I come here ?

 

i dont think there is a difference is there? well if you need it let me know.

 

89 is the first year of VATS I believe. But I know they did away with the 9th injector in 89.

 

VATS completely slipped my mind. You are correct. When did they remove the 9th injector ?

 

89 was the first year without it as far as I know.

 

It was all explained in my PM.....
