Hello, I ordered a Dinan Performance chip off of ebay, and im trying to figure out if i got the wrong chip or if it is defective.
I have tried re-installing the chip 3 times car will not ignite with the dinan chip installed. factory chip is fine.
BMW 1987 325
0 261 200 027
1 708 643.9
off on the right hand side of the ECU the numbers (078) are circled.
Supported ECU: 0 261 200 027/021
any ideas? from everything i can find this is the correct chip for my car.
EDIT: Car is also parked on a hill will that effect first fire?
