hows that ford going i can give some help if you still need it

does this mean exactly what is says?

torque max.png

should this be maxed out to get rid of some more torque management?

[Russ K]

Never had a reason to change that table. I just disable the trans torque management drop down boxes.

what exactly here are you disabling? master and shift? if those two are disabled does that disable all torque management for the trans making it not necessary to mess with the upshift/downshift torque reduction?

also, what is truncation?

[Russ K]

Yes, just need to disable the master & shift drop down boxes. The truncation is also some type of torque management, but it is already disabled in your tune.

It means what it says, its a torque clip in park or neutral. A lot of times this is the reason for the neutral rev limit.

how does this affect drivability? this shouldnt mess with shift speed or firmness right?

so im guessing the neutral rev limit is 4000 based on the table?

Yeah

It just eliminates spark timing retard during upshifts & downshifts. You must raise the trans shift pressure tables to prevent slip when disabling the trans torque mangement.

so if i disable the trans torque management i should also, at the same time, increase the shift pressures to keep the clutches from slipping?

Yes, that's what I said in post #30.

im guessing that the upshift and downshift pressure, desired upshift time, and clutch fill time will all need to be modified after disabling torque management?

any threads or ideas on where to start modifying these tables so i dont kill my tranny?

I just add 20 psi to the entire upshift pressure tables, no need to change the downshift pressure tables. Then fine tune your upshift tables by adding or subtracting 5 psi at a time until you get the shift firmness you like. Leave the desired upshift & clutch fill time tables stock.

is there a way to make a histo that mimics this table?

trans 1-2pressure.png

seems like i would need one to set part throttle and wot firmness separately. id like a firmer shift part throttle and not neck snapping but wot can can be harder.

or will the table just work itself out like that naturally but adjusting it the way you described across the board?

Works well the way I do it, has firmer shifts at high torque loads & softer at part throttle.

yeah thats what i figured after thinking about it for a while. guess ill have to try this out soon and see how it feels.

anything specific for the trans i should be logging?

[|V3nom|]

another question, how does disabling the master torque management affect acceleration before/after shifting? does it put more power to the ground? i cant find anything about non-shifting (normal driving/accel/decel) transmission pressure but since theres 2 torque reduction settings, master and shift, im assuming 2 different things are happen, one is shifting and the other is everything other than shifting.

am i close or way off?
