Lost i3 Tuner

[deviatone]

Hey folks,

A few weeks back I had my tuner on my desk, and it seems to have walked off . Whether lost or tossed, I am most likely going to need to replace it.

I have a few things set on the truck currently, 91 tune, speedo fix, and firmer shifts.

What would I expect to happen when I get a replacement? I don't have the stock tune (it was saved on the i3) Am I stuck with having to get a replacement PCM/TCM as well or can a new i3 default or remove other settings? Or can I DL the stock tune somewhere if needed.

My new Monster trans has firmer shifting so the firmer shift tune is not necessary (in fact feels like a hammer in 2nd gear)

Appreciate any insight, and guidance.

What vehicle is this specifically?
No copy of the backup saved somewhere?


Thanks

Its a 2001 Suburban LS 1500.

No backup unfortunately. Made 2 changes and put it on my desk.

the early GM scan be tricky to get back to stock.
Better chance of doing it with a P2 than the i3 honestly, and even then it may require a dealer visit to get flashed back to stock.

Thats what I was concerned with. Guess I'll try once more to rip apart the house, then if necessary bite the dust and get an appt at the Stealer.

is that 2001 old enough to where he could get a ecu from a junk yard that wouldn't need the relearn pin from the dealer? I wasn't sure if finding a ecu from a junk yard would be cheaper than having the dealer reflash his. I know my GM dealer charges 250 for a ecu flash. I asked before I bought my i3 in case i messed something up lol.

Most any pcm change here would require a reflash to get the VIN in there and make VATS work.
