Are this readings ok..If not what are the reading should be???

Do you have a MAP wired in? Its showing 2 maps with different readings (mmcd throws odd numbers out for values not set up). From the looks of this your higher rpm log is pulling a lot of fuel in your low and high trims, but your only at 50% throttle. If your running stock boost, on a stock injector (stock pump?), why use a gm maf?

I'm running 3" gm maf-t coz I'm planning to put a 650cc injector, 190 pump in and a 16g turbo.. Have a fmic and a hks bov as well..Don't have the map wired coz I'm using the gm maf-t to adjust the air and fuel..My wideband reads at 14.7 at idle 10.1 on wot 10psi ocz I have a boost leak from throttle body shaft..

Since your in a 1g and have a WB and all the other accessories, Id mainly keep an eye on knock and tuning for knock at WOT. The other information from mmcd, since its not adjustable through the program, is only good for checks and balances. It looks pretty standard for idle and cruise. Your ISC counts are a little high, does it surge? You mentioned boost leaks, that could be a cause. Still might want to run through a biss adjustment if isc counts at idle, when up to temp, dont go any lower. You were still warming up on that log. Id try to get the fuel trims in line to =100% +/- 5 or so.

Maybe someone on here can point you in the right direction with maft tuning, as Ive steered clear of the gm mafs. Just reset your ecu so your trims zero out after adjustments and see where they take you.

Thanks Dude Mcnee. I'm still waiting for the tb shaft seal to fix the leak. I haven't done that much tuning yet, not till got all the leak fix...The timing look ok to you? Seems like it move too much..

 

[Dude McGee]

As your cruising, timing will be all over the place. Idle too. It is always moving. At WOT youd see a more xonstant number.

This page has an image of the timing you should see at 10 psi.
