New PCM update for 2002's?
Hey folks. I recently posted about a problem I was having regarding pinging/KR. It isn't that bad but I wanted to see what was up with it and how I could possibly fix it.
Somone posted about there being a new PCM update for '02's (or for every C5?) that attempts to "fix" the pinging problem but as a result, performance is hurt a little (more so for A4's than MN6's). Anyone know anything more about this? I am taking the car into the dealer for some service work and am unsure about whether or not I should have them update my PCM. Thoughts? :)

I had this done on my 2002 coupe a couple of months ago for the same problem, as did a couple of other members. The update retards the timing some which is where the claim of slightly reduced power arises. I couldn't tell the difference on my MN6 in terms of drivability. Plus, I'm still getting a bit of pinging. I'm looking at other reasons for this.
I would go ahead and have the update done since there are other changes included, although I don't remember exactly what they entailed.
Be aware that you can't go back to the previous programming once you have this done.
I'm looking at h/c in the near future so dyno tuning is on the list to revamp my PCM.

Why? Companies like Fastchips, TTS, etc. typically adjust the timing up & down to maximize performance.
Other members who've had this done were told the same thing. :yesnod:

Is this a common problem for 02? I have noticed some pretty bad pinging under WOT, but it seems to go away when the outside air temp and humidity drop. I did an autotap and saw a max KR of about 1.3.
