Don't worry about getting an 02 PCM. Your 00 PCM will work just fine. You'll just want to upgrade to an 02 Operating System (12212156). You can find one on www.holdencrazy.com in the stock tunes section.

Regarding your fueling issue. It could be your pump, but definitely looks to be something along those lines. When you first nail the throttle, the system starves for a moment before recovering (as apparent by the dip in O2 voltages). I'd check fuel filter and pump.

Just got back from a log. Didnt go into boost at all. Figured out the my inline pump was not working because of a bad relay. Got that all fixed for the run. Still getting some KR. Looks to me like my narrowbands arent hitting the .9XX at all. Havent got the wideband yet so i can confirm. Check out the log and tell me what ya think.

Ok. I got my wideband installed and now im ready to start getting my fueling down. Can someone help me in this area. I have to get the lean,KR conditions fixed before i can really start tuning. Any help would be great. Thanks

Are you now setup to log the wideband AFR? i.e. wideband output connected to the FlashScan unit and the appropriate PID selected?
(see EFILive tutorials)
