Checking out tune w/o WBO2?
Wondering ... I will be checking into a 98 F-Body next weekend that has some mild mods and had been tuned by some tuner ... car doesn't have a WB, so with most of the experience I have from tuning my car (which has a WB) I'm not really sure how much I can check ... Any suggestions as to which PIDs to logg and what to watch out for (except for the obvious: NBO2 values, knock, ...)
Tnx!

If it's just bolt-ons, I wouldn't worry too much. Just make sure the timing is jacked up too much over stock and the AFR isn't leaned way out. The earlier models really didn't need a lot more timing - mainly fueling corrections. If that stuff looks ok and the fuel trims aren't way out of whack, it should be fine.
If you're going to log it, I'd go with these (plus the LTFT pids):
Not really just bolt-ons as far as I understand it ... but as I said, it was already tuned (SpeedInc), so unless they messed up, it shouldn't be too much to need changing ... (it's a 98, so I can play around with it ...)

Well that's a little different. Being tuned by a reputable shop vs. "some tuner" is a little different.Originally Posted by Garry
On top of SSpdDmon suggestions, you might take a look at the LTFT's to get an idea of what the PCM is doin for fueling.
That said, I've seen some pro-tunes with WOT timing in the high 30's and PE AFR in the 10's...
LOL i`ve see that before.
