I was looking to see what computer i have, '746 so that was good. Anyways, I was curious about the chip and this is what I Found... Red Sticker on the chip itself looks like it says "Hyper Chip" and handwritten on the under side reads "9002 B".... wondering if anyone has any idea what chip this is and any other info they can tell me about this setup?
Car is a 1991 Firebird, Vin "E", 5 spd
Looks like a Hypertech chip. To know for sure what type of PROM it is you'll have to remove the chip and carefully peel back the red sticker and read the chip type. Don't peel back too far cuz you'll reveal a little window that when exposed to sunlight will probably erase it.
