tow/haul mode

Post by trucks2361 »

2010 Silverado 1500 w/6 speed. How does tow/haul mode effect a Diablo ecu/tcm tune? Does the Diablo tune also change parameters in tow/haul?

tow/haul works the same as it always did, tune changes still apply, so more power no matter which mode.

thx for the reply. what about the diablo trans tune? The standard diablo tune changes shift points and shift TQ correct? doesn't the tow/haul also do this with the factory settings? so does the tow/haul alter the diablo shift points and other options?

No, shift points are not changed.... the preset canned TCM tune changes shift pressure/firmness, and shift quickness (how quick it performs the actual shift)...

You'd still use the tow/haul button like you normally would. That tells the transmission to use different shifting settings for towing (higher shift points), same as stock tune does...
