The odd stumble is probably fuel related. Vortec heads and TBI right?Originally Posted by Jimmie
Looks like this took care of the weird SA glitch! I was hoping this would take the odd stumble out of it but at least now it will be solid data to go on. Thanks everyone for the great help on this!!!
Yes, vortec heads, TBI, flat top hyper dual vr, rpm air gap intake, bored out tb. It is a dog below 2000 and stumbles like the key is turned off, shows lean off the scale on wb02 then after it downshifts or reaches 2000 rpm it screams to life. I have actually killed the engine by flooring it, but nothing seems to help very much.

Email me the injector size, fuel pressure, current base timing and the bin file and a datalog .xdl file running on the current tune as well.
When I get back into town this evening I will look at it. I have a few ideas for it.
Here's the latest information email be me: see attached.

Data logs using updated .adx with altitude SA Zero and altitude SA 9.8: see attached

From first appearance looks to have way too much spark advance.
I will look at the actual bin when I get home.
My guess is that it does not have enough fuel in that area in the main fuel map. No amount of AE will permenately mask too little fuel.
