Desired Shift Time

[A6sportsracer]

Hey Guys/Gals,

New member here, studying EFI Live tuniing and scanning. In the tuning calibrations under DESIRED SHIFT TIME there are parameters for 1->3, 1->4, 2->4, 2->6.... shifts, when do these "skip gear" shifts occur?

If you are accelerating with a high TPS value up to the top of a gear, then let off the throttle, the shift will skip a gear or two (or three) according to the upshift table.

that simple enough,
Thanks. I'll have many more question.

When does the Trans use "Base Desired Shift Time" as opposed to "Desired Shift Time Input Torque Mode"?

eg. D9000 or D9005

I think it adds the "Desired" time to the base shift time to get the final time. Less engine torque programmed for slower, softer shifts. The stock 2010 Camaro has some " .000 " shift times and longer "Desired" times and the Denali has longer shift times and shorter "Desired" times.

Could you post a Camaro 6L80 file? I be interested in seeing it.

I will try to post it, we'll see if it works. If it don't, PM me your email and I'll send it to you to post. I'm working on tuning mine now and it's close to where I want it. I have deleted all tq mgt and it's shifts good execpt for being a little too harsh on downshifts. Anyone have any suggestions?
