does anyone have a tune file with the propper stuff cut off to tune the VE that I could look at? Or a link that has a good how to for the newer VCM?

Yup. Set your dynamic airflow to 1500/1400 respectively and call it a day.

Leave the MAF plugged in, it also provides IAT.
If you would like to disable the MAF then go into Engine Diag, Airflow, and set the MAF Fail High to 0.
Also go into the DTC table and set P0101, P0102, P0103 to 2-No Mil Light.
You can verify the MAF has been disabled while running the car by looking in the Scanner DTC window and you should see a P0103 logged in there.

Thanks, I'm going to try this tomarrow.
Ok I've got the idle pretty good, the AFR is 14.6-15. There's a stumble at around 2k when shifting into 2cnd gear. It's bad enough that it cuts out and will backfire, then clears right up when the revs reach around 2500rpm. Anyone have any idea what this could be?
The car has a ported head and [email protected] cams.
Please look at what I've started with the tune and give suggestions.
log file?

Here's a scan with the MAF turned on. It seemed to be better until I pulled back in the yard. Then it shut off and didn't want to start back. It would back fire when trying to start and I think it killed my LM1 sensor. Now the LM1 is showing "ERROR 04 OPEN PUMP" any idea what that is?
Here's were I'm at with the MAF tune.
you should remove all of those Bank 2 pids from your pid table in the Scanner.
they will probably skew your results having them in there.
Add a few more pids while you're in there. Total KR, MAF hz, Baro sensor, O2 voltage, IAT2

Your VE table is way out, this is responsible for part throttle transitions and will affect the fueling during shifts. If you spend time calibrating your VE it should smooth everything out.

should you always use ve when below say 1500 rpms? and leave the ltft the same? i have stumbling probs at idle with maf.
