Feature request TCC Lockup curve

Post by 280GE 1JZ »

Hi James,

Is it possible to create a TCC lockup curve based on load and speed? Or is the feature already there? Thanks.

It isn't there already, there are TPS, RPM and VSS thresholds.

Hi James,

I just found this issue last week when I was on the dyno. I set the TCC lockup speed to 200kph so it wont engage during dyno but it still engage at 50. So I set the max TPS value to 0%. 50kph was the speed I set for 3rd gear in lockup each gear setting. Is this normal? Thanks.

Regards,
Doddy

My hardware are MS3pro with prealpha7 and GPIO with trans firmware 028

The "Lockup speed" in the top left is no longer used. Only the RPMs/VSSs to the right are used.

The next release (in a few minutes) will have that rogue setting removed from the screen.
