Backwards chip?
 

this might be a good question for you ecu chippers. I removed a 27c256 eprom from the zif socket in my ecu today. I installed it in my new burner just to make sure the burner was working properly, and I had the burner read what was on the chip. Then after it gave me the info I re-installed the chip back into my ecu, but I wasn't sure which direction the chip should face. So I just guessed...
Well when i went to start the car, I had a check engine light and it idled up and down. I also tried switching the position of the chip and that had no effect. What happened? Did I fry my ecu or just the eprom? Is it possible to loose data on a 27c256 chip without erasing?
Any help would be appreciated. )trance(

The little Grove on the ship that looks like a little "U"
Faces the Ecu plugs and on the burner it faces the Parallel port.. (batronix at least)

Awesome!!! Thanks for replying ASM. I'm still waiting for some more chips to come in. Maybe this time I'll do it right.
