Actually if it were made in Canada it wouldn't have been screwed up. :P

You might need a tweak to the Acceleration Enrichment table in the PCM. This table is used to give a brief burst of fuel when you punch it.

Yep, not to mention the famous PE vs TPS (or Adder vs TPS for the HPT guys).

9.0:1 is extremely rich, emphasise the extremely rich part. You will eventually have problems with fouling and carbon buildup at that rate.

Your car should make 'safe' peak power at around 11.5:1 , for the more adventurous somewhere around 12.2:1 would do it.

What'* the AFR while experiencing the KR?

Cheers,

I really don't want to become a PCM programmer.....PE vs TPS (or Adder vs TPS for the HPT guys)........

The first number I saw last week was 9.5 and yes I know that is rich but after turning down the fuel pressure a bit, the other day it was showing 10.9 which from the sound of it is just about right.

I wonder if INTENSE could tune my PCM from a distance.....

Ya, I'll bet it has something to do with it.

I think when the KR is present the AFR is around 15.x

If you got a scanner with logging capability for a while and worked with Intense..I believe you could probably send and have them analyze a bunch of scans to come up with a reasonable tune.

Caveat...the minute the weather conditions change..the tune needs could become different.

Not to sound like an ***...but at your mod level it'* not about wanting but more of needing to become a PCM tuner.

I'll be the first to admit that tuning is a PITA. It can be tedious and overwhelming at first. However, once you get your confidence and knowledge up, it can be very rewarding to make a change and see the exact results you want.

After two years of tinkering with tuning...this is so true. A 15-20* degree in temparture change impacts my fuel trims more than I would like.

If you'd like contact info for someone with lots of experience who will do a long distance custom tune for you, drop me a line.

Otherwise, I've found humidity to be a very large contributing factor to changes that affect the tune. I'll bet that you being on the left coast that may be more of an issue than temperature (except for very large changes).
