I just installed a 100mm LPE MAF.

Nice joe!

where is the MAF Hrtz vs. rpm different from the stock MAF? How much resolution did you pick up.

Howard,
I'm only comfortable up to 4125hz. After that it goes to 0 ltft's. I need to get on a long clear road to get enough information.
At 6100 rpms map went from 94 to 98 kpa and the maf g/s line has no jagged spikes at all. It's smooth. I returned most A/F tables to stock, except for TCracker and that makes sense since I have a 3600 stall and an A4. I had to create DAF and VE(VE only close until I get motivated).

I missed the resolution answer.
The LS1 Maf table goes from 1500 to 12000. The LS7 from 1000 to 12200. I won't use the outside values, so nothing lost. But the LS1 values are 125hz apart vs 150 for the LS7. By filling in values I picked up some resolution. That was a lot of work and I'm not done. I think I'm close, though.

so did you have to change the reluctor wheel,
or does the LS7 have the 24X from stock?
if you changed it, did you have to completely disassemble the engine?

It's been converted to a wet sump and a 24x C5 reluctor wheel. Skoggins Dickey will convert it for a small upcharge and warranty it. Theres no point in converting it yourself.

ahhh

Despite opinions to the contrary, there is just NO replacement for displacement.

Except for boost!
