746 ECM/emissions delete chip
It's a chip with the emissions deleted on it. The previous owner of my car (A TGO'er 
) bought it for when he was removing the AIR/EGR and other assorted federal offenses to clean up the engine bay so that it woudlnt throw a code all the time.
It also has lean cruise mode activated which, from what I understand, isnt something that's enabled on stock ECMs, so in theory you'd get better gas mileage. If you've got an Air/Fuel gauge you can actually see it (Which is how I found out it was enabled!) do it. It usually goes on and off with the torque converter lock up. They usually went hand in hand.
The previous owner told me it was fine to run it on 87 octane on this particular tune and most of hte time I ran 87 octane in it and I never had any problems. The engine was mostly stock, had an open element filter and the emissions stuff taken off, not much else.
He got it done for him by the guy at tbichips.com.
I have no idea what something like this is worth, so just make an offer. I've heard ridiculous things about what the guys that do the burning charge for these things but I'm not convinced they're worth that much.
I'll throw in the ECM with it, and the goofy plastic holder with that.
Just make an offer. It's taking up space and I figured someone might be able to use it.

For the record, I ran this with my long tubes and 3 inch dual exhausts that I had on the car about a month before the 350 went in, and it never idled right. Could have been because I didnt use a heated O2 sensor, could just be because the huge exhaust threw off the tune really bad. So if you're looking to go LT's and huge exhaust, just be aware. It would likely work a lot better with shorties. That exhaust I had was WAY too big for that motor, and I'm sure that had something to do with it, but it always ran perfectly with the manifolds and catback on it and I had it like that for about 10,000 miles (a year) with no problems at all.
It idled steady, it just idled at around 950 RPMs or so:

Ran fine other than that, though, but Im sure without the heated O2 sensor the ECM wasnt really getting very good readings, and the AFR gauge supported that. The readings were way different afterwards.
