How to lower Trans Engine Torque calculated in tune

Hi

I am chasing a Transmission shift command problem that occur only when the Transmission Engine torque is over 1000Nm, If in some log, I stay under 1000Nm Exemple 996Nm That I got some time for no reason, transmission shift where I wanted.

Can someone point me in witch table I can change the value to lower this torque calculation value ?

Thanks

I believe this is what you are looking for...

Do you see it?

Also there is way more that can be done to tune that trans... P.M. me.

Also, am I reading you right that you are actually producing over 1000 FT Lbs of torque? What mods both Engine and Trans?

Hi

I managed to correct the calculated torque in the tune, I now see about 850Nm at Shift, This have solve 1 of the problem of shifting too low, So now it shifted close of my shift point, but still flare few 2-300 Rpm before shift.

Here are my Mod:
405Ci fully forge Block
Ported head and intake
Vortech V7 race blower at 18PSI
Custom Water to air intercooler

Transmission is a fully built SHR war viking Max capable of 1400Hp

Car actualy ran 9,82 sec at 138MPH at 4600 Lbs car

Hi Magmax06,

How's the torque behaving? Have the same issue with my turbo Jeep SRT... too much torque when shifting to 6th gear and PCM closes throttle and injectors around +120mph (scary sh*t at those speeds white wot). Care to share your method of correcting (lowering) the calculated torque?

Best,
Daniel
