Your making the number bigger in the VE table section that matches places where the BLM is higher than 128 in your logging. This is making your pulse-width longer, which means more fuel.

So if I modify the MAF tables, increasing the number makes the ECM think there is more air coming in or less?

Now I see why everybody swaps to the '730 ECM and SD!

They swap because that Maf mazes at 255g/sec. A 350 with bolt ons pretty much hits that wall. After that you're guessing on fueling.

So tuning with VE tables is no easier than with MAF tables?

VE is easier. Less tables really.

MAF you're doing the same thing. Just the sensor is a limiting factor. Plus, when they die, they're more expensive.

Anyone figure out how to put a late model GM MAF in a turdgen?
