Tb

[kissmyss]

I just installed the ZZP stage 2 tb I purchased on Black Friday. I didn't have my camera, so no install pics. I'm in touch with Will concerning my Pcm and since she will be parked for the winter I have time to get that taken care of.

Skewed the MAF readings with the ported TB, huh?

Yes, but full throttle from 30mph = no kr and the short term/long term fuel trims lock at 0 during acceleration. I get slight kr during full throttle from stopped until transmission shifts. Idle went from 790 -810, to 770-785 and it's not rough or fluctuating.

Here's some info, although I haven't had time to get on the highway. The following info is at idle, rpm 770-785, no rough or rolling idle and no kr. Maf = 2685-2695, Map kpa = 37-39 Ign adv = 25.0 and Lt trims fluctuates never higher than 6.2. This info is part throttle from stopped; Lt trims fluctuates 12.5 - 14.8, Maf fluctuates 6350 - 7000. The following is full throttle from 25mph; Rpm 4010 - 4200, maf 9000 - 9200, kr = 0.0, St and Lt fuel trims lock at 0.0 during acceleration. This is the best full throttle scan I could get until I can get some highway time.

Btw, I did notice kr during full throttle from stopped until the transmission shifted. I won't be doing this often, tires can be expensive.

Just installed the re-tuned pcm from Will and the car feels more responsive. I also received a free set of Ngk Tr6 ix iridium plugs, from a friend. The Al 104's are two years old, so I'll replace them. If the ngk's don't work out, I'll buy some more Al's. I'll be sure to post my results, any suggestions on what gap to use? The Al's were fine with a gap around 52, the ngk's appear to be at 35.
