Hey y'all, would any of you guys be able to write me a tune for a 1999 corvette M6, K&n intake, Long tube headers and rear o2 sensor delete. Here is my original tune. Thanks Guys!

need to post up both the current tune that's installed in the car (last tune written), and also the original backup tune... can't do anything without having both files...

do you still have CAT's on the car, or no?

well, here's your tune with the rear O2's disabled...

if you don't have cat's on there anymore, lemme know and I'll write ya another one to disable the COT strategy as well, and the CAT codes...

after you install the tune, put on about 75 miles, then do a data log to see what your average ltft's are... then you can adjust your injector slope accordingly to get them into the 0 to -2 range, and that will have your fueling adjusted correctly for your headers and you'll be all set.

here's info on logging and making the adjustment:

Thanks Lew, I appreciate you writing the tune but I tried to install the tune and it says that the cal id's are wrong. I appreciate the effort from everybody at diablosport but I think there is something wrong with my pcm.... I checked my ltft's and the're at 25% WTF !?!? I think I'm going to order a completely new pcm from pcmforless and sell my u1798 to somebody who wants it. The only problem I have now is that the unit no longer recognize's my cal id's, how do I force the original tune back? Here is a log just to show you what I mean about the ltft's

did you get your PCM updated at the dealer? if you did, was the stock tune returned?

I had my pcm updated before installing the predator unit

hook up the predator to your car, and go into options/troubleshooting, and there's an option to display the calibration id's...

post up the list of the calibration id's that is shows....

k... will have to wait til monday when the diablo boyz are back at work.... they'll be able to tell ya what the deal is with those...

but I'm guessing, that either you'll need to get an ecm update from your dealer, or they'll need to make a new revision update for the predator to support the cal Id number you have...
