No idea what this is.
Me and my father have recently bought an '89 Trans Am GTA and are in the process of fixing/restoring it. While the cars got plenty of other problems, I figured this would be a good first post. What is this thing? found it in the glove compartment and really have no idea what it is or does.

Re: No idea what this is.
Thanks for the quick reply. Does it need to be plugged in anywhere, or is it a just-in-case thing?

Re: No idea what this is.
Looks like in case thing.....should replace the original chip.....or maybe that's the original and there's an upgrade chip in the ecm now?

I'd put that one back in for reliability and sell the after market one on eBay.

The ecm is under the pass side dash.there's two 7mm screws in a plastics bracket facing the carpet. The ecm slides down and out.there's a door securing the chip in. It just pills strait out.

Re: No idea what this is.
got it in one.It was a Hypertech. Ill keep it for now, and put the stock one back in. Once the car is up and running ill change the chips out again to see if its worth keeping. Thanks for the quick help guys!

Re: No idea what this is.
Im not really sure. All i know is the light that said "security" stopped turning on after i changed the chip back to stop. Also, i dont know if this is related, but there was gas in the oil when the car arrived on the trailer, wich led us to believe the engine was flooding. Since i have been led to believe the chip controls fuel/ ignition timing, is it possible that it was the chips fault?

Re: No idea what this is.
could be an injector. There was ALOT of gas in the oil though, so i wondered if it was possible the PO was just as stupid aas it seems from the wiring job he tried for a back speaker, and bought the wrong chip.
