Computer chip question
How do you know if your chip has been retuned or replaced with a performance one? I am asking because my computer is not bolted in to the car and just rests up in the spot it belongs. I was just wondering how to tell if someone before me has done something to the car. I am in the process of installing a supercharger and they are specific about using your stock chip so to avoid detonation due to the advanced spark curve of an aftermarket chip. Just FYI I have owned the car for about 9.5 years so what was availible back then.
Thanks.
Thanks.

Well I did pull it apart before posting and it is a Delco part but that doesn't rule out it being changed does it? You can change these, as in burn new info on them, correct?

Usually if you take the chip out, if its an aftermarket chip it will have a label from the vendor. Most people will use a chip from a commercial vendor such as Hypertech or Jet, both will have a label that will make it pretty obvious. A tuner may have reprogrammed the original chip, and if that is the case, it may not be so obvious, I usually apply a sticker to the chip that ID's it in some way so that I know what is in the chip. It maybe meaningless to someone else but that is just how I do it.

I had a tuned chip in my 86 when I bought it. It was the stock chip that had been tuned and not a piggyback. The place that tuned it placed a label on it.
