My 99 pings like a bitch. Even with the tune and 93 octane......
wtf to do? swap for a 02?
Let me edit this. MY engine is a freakin 02, and the pcm is a 99...would this cause some false knock???

It's just the PCM man, but when you had the tune did you let Allen know you had an 02, this could be the problem, I think the 02's have different cams. The 99 PCM's suck, tuning can take care of alot of problems with them, but its just the false knock problem that takes away alot of timing.

At the time of the tune, I forgot to mention that to him. My 99 engine locked up and I had it replaced with one out of an '02. I never thought that might be the culprit.
are the problems always with the 99's?? and are the always same stuff??

Let's face it, the red hair... makes 'em wet.
does upgrading to an 02 pcm cure the problems or at least help??

That helps with the tuning, but I mean mechanical issues. ABS module, driveline bits, etc. My truck was a POS by 64k or so when I traded it... never abused. Leaking window seals, window reg took a crap, on and on.Originally posted by 34coupe@Apr 19 2005, 12:37 PM

You couldn't GIVE me a '99 to drive.

I am thining the retune Allen just sent me was an 02, I cant remember if he said he was going to try it this time or not, but even with Allen's tune I was still getting ping and not a whole lot of response even after we got the tune taken care of, the high end was unbelieveable. but the low end needed work. I'll let ya know the diff by Thurs when I get it in.

I'm guessing that I need to upgrade too, but what's the difference in the price between the 99 and 02 pcm? I'm thinking of getting a shift kit/servo so I can safely get all of my TQ Mgmt removed as well... That should wake it's sorry ass up rite?
