i have a standalone ecm for a 1986-1992 camaro tpi engine for sale, i got it to use in a twin turbo iroc project but sold the car. now this is sitting on a shelf. here are some links to what it is and what it does. i had the car running on it for about 2 hours is all but the buyer of the car wanted it all original so didn't want this. i can tell you that the difference in power on a stock engine compared with this ecm is drastic! tunes on any laptop

i had about 18 hours into the assembly and tuning of this unit can also be used on any fuel injected vehicle by changing out 1 board on it to be a plug and play in several different cars.

just thought i would see if anyone on here is interested as the guys over on the camaro forum are afraid of the tuning that it needs .

looking to get $300 or trade for it i also have the tuning cable for it and the serial to usb adapter!
