Might be picking up a M45...on a deal I can not pass up. My cav might be supercharged before I end up doing my LG0 swap.

John can you send me your buddies file?

John can I get that file too? I think i got my histograms setup wrong. Does anyone have some good histograms i cold get. If i do afr error in open loop my afr is all over the place. If I tune in closed loop and use afr error I get super rich, and if I use fuel trims its seems like the wide band will flicker between 14.3-15.1 and it says I need to add allot more fuel. So I'm really confused. Any ideas?

I really should get Darren's tune up onto the repository for you guys... in ran a bit rich but it ran perfectly with his S/C setup on the 99 PCM.

It even had room for some additional timing but sadly the car never saw a dyno for me to do it.

Mike, what is your email address? I'll try to remember to send it over to you tonight

I forget what size Darrens injectors were... I believe the cobalt ones were too small and he stepped up... you'll have to PM him.

Either way it was running a bit rich under boost, but when I tuned it with no cai/air filter it was holding 11.8-11.9 SOLID through gears 2-4... and as I said it's running stock GMSC timing so it had some room for play. Darren was hitting 8-9 PSI I believe, plus his charger was ported. But it's a decent base and will show you how the tables switch over.

At low speed / traffic conditions it ran like a stock N/A Z24. It was really nice!
