ive been lookin around on the internet for a couple hours for ecu files for a 1228746. now maybe im just dumb and couldnt find any , but i had no luck. my car is a 91 rs 305 tbi 5-spd. my problem is vats and who knows what all else (bought the car from somebody else, i just know the keys arent right and it wont even crank). if somebody could give me a link to a website that has a definition file for the 8746 ecm's, or send me an email with it or whatever, it would be greatly appreciated. im lookin forward to getting this car running and on the road, but at this point...it aint happenin. and i cant go pullin all the tpi stuff outta the parts-car formula yet till we get the other iroc straight. so yeah...definately needing those 8746 definitions...lol. o, and if it matters, im using tunerpro (the free version), and since im cheap like that i'd rather not pay for the definitions lol.

thanks,
mike
