I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.

Excessive timing retard wot downshift

Hi all,

having some trouble getting around wot downshifts 6L90.

ive Had great results with limiting up shift timing retard.

im seeing massive timing retard on a wot downshift, I’d like to reduce this. I have changed the max torque timing in the ecu.

is there a way to soften the retard without manipulating minimum spark advance?

cheers.
