MAFLESS VE Tuning
Also, check out the HP Tuner forum. Somebody finally posted a Holden MAF table for us. It looks similar to what I was expecting. Might be worth a shot with a lid. I will try it in a day or so...too tired to put it in tomorrow morning's tune.

I actually do it backwards I modify the primary (even though I know it isnt looked at and the scanner is setup for the primary) and then copy to the secondary. My trims are comming around also. I did some logging last night and some tunning i will get a better feel for how well i am tonight. I may copy and paste those maf tables tonight jsut to see if i am able to plug it back up. Will post later to let you all know how it went

Okay, got the why from the other posts... The tables you're modifying are VE vs. ??
If you have HPTuners and you see two ve tables when you disconnect the MAF the PCM will use the second table
If you see one table when you disconnect the MAF it will use the primary
There are two VE (Volumetric Effieciency tables) Primary and secondary

so I guess I'll just keep on spectatin'. Being as I also
have not seen nearly the trouble you guys are having,
and seen VE adjusts push properly on my low-end trims.
There's something really screwy about all this. Like we
all live in different worlds. Maybe it's the early / late
model thing.
The pcm uses your MAF sensor to apply tranny line pressure. with it disconnected you will command full pressure to the tranny at all times and burn out the pump. Another_user and I are stick cars so we can get away with it

You have an 01-02 by that time they did away with the secondary table. We both have decent sized cams with a good bit of overlap and that may be the reason why it seems we live in different worlds



The edges may need to be cleaned up a little, there are a few cells I couldn't get to, like some of the 400 rpms. FYI, I started with a 2002 Z06 VE table to build this.
