Upgradibility to 2001+ MAF?
I know people upgrade pre-2001 C5s to the 2001+ intake manifold (Z06 type) when modifying for max performance, but what about upgrading to the larger 2001+ MAF? Does a MAF change require a programming change?
Also, is there any difference in the throttle body with model year?

I don't believe you'll need to tune. The newer MAF ( LS6) already has a new transfer function within it's electronics for developing frequency output. You might post this question in Scan and Tune.Hope this helps. :cheers:

I have done the upgrade. If you don't have ls1 edit you need a Maf translator to convert the signal from the newer maf to your computer.
Things you'll need
Connector to go to the newer 5 wire Maf
Maf Translator
Some basic wiring skills.
If you have ls1 edit go over to ls1 tech and they can give you the new maf table for the newer maft.
I personally think it is worth about 10 rwhp but have nothing to back it up since I haven't dyno'd the car since the change.

You can get 85mm MAF's from SLP and other vendors that are like the '01+ MAFs'; IE: they have the IAT/MAT built into it and have seperate harnesses for each. These are already calibrated for 2000 and below PCM's.
The only thing that has been holding me back is you'd need a 2000+ air bridge and filter for the extra 10mm diameter.

Re: Upgradibility to 2001+ MAF? (rockgt302)
You can get a coupler or bellow to make the fit. I have a pace LS6 maf, it came recal for the older pcms with all the proper wires and bellows. So you dont need the newer bridge.

I just can't picture how the coupler would work. The MAF clamps directly to the air bridge, and the bigger issue in my case would be how to connect it to the Votrex. I suppose I could open up the hole in the air box and the filter may stretch over the MAF. I called BPP and they said it would be best to replace the filter and box with a '01+ version made to accept the 85mm MAF. That's what made me start thinking that the stock MAF is fine, especially with my limited mods.

So this change will yield a 10 hp gain on a stock vehicle and more on a modified one (H/C, stroker, forced induction)?
:D :) :D
