ok i have noticed a lag when punching it from a roll and i noticed the timing drop..
now besides that my tune feels and works great
here is a punch from 54 or so and a few dead stop logs...

i have TM disabled for upshift and power downshift i guess one of the other tm tables in the tranny side is doing this...

any advice is welcome


the roll is log AA

[04blackgmc]

as you can see from 1800 to 5000 rpm's its dead on the timing

[04blackgmc]

no one?

We need your tune, the log is worthless without it. You probably have a torque management pull going on.

Have you changed your tune since the last one you sent me? If not, maybe some bad fuel or too much ethanol.?

[04blackgmc]

here was the tune

[04blackgmc]

changed a few tm things still there....

I don't see anything in your tune that would cause such a huge timing pull. It is diffenately not your tranny. Put some Octane booster in it or a wiff of race gas and see if the timing comes back. Thats alot of timing pull from what you are commanding.

no knock or anything

Same problem mine is having. A couple reputable tuners have all looked at my tune and my logs and both said the same thing, they cant see anythig in my tune pulling the timing.

My guess is still something ECT related to the timing pull.

oh this is the issue you posted up about now i remember

[04blackgmc]

ok i think i figured it out its in the tranny somewhere...

here is a few logs to show
qst log you will see i am holding the gear and not letting it downshift.. already selected the gear..

2nd log i let it downshift look at the timing drop

Yeah Kirk At Vector Motorsports Said There Are Still Some Limitations To Hp Tuners That We Dont See In The Torque Management Side That They Can Access And Change.

They Use Another Form Of Programming Which From What I Gather Is Close To Gm Stuff So They Can See These Tables And Change Them If Need Be.

well im just glad i got it figured out, ive been meaning to test this theory but kept forgeting
