How can i tell if the stock ecu has been reporgrammed??

Ok, i bought my car last summer, it came with a downpipe and custom catback exhaust. I was wondering if the ecu has been reprogrammed. Can someone post a pic of what the stock ecu looks like? and if it has been reprogrammed what should i look for on the ecu?? Is there a sticker or some sort of label?

No I think usually you have to look on the chip inside to see who it was reprogrammed by..

i am pretty sure your ecu will be stock since you only have the downpipe and cat back.

as for the ecu, there is no label, you will need to take it apart.

There are two boards inside the ecu, the stock version looks pretty plain and simple. Reprogrammed ecus have an additional daughter board where the eproms used to be. You'll have to carefully unfasten and lift one of the boards to see it.
