Thread: GXP vs a Comp G

TapShift makes the car slower.

Proven.

Should have ran him and told the silly guy to leave it in drive.

Good kill though.

What? please point me to that thread

TapShift has different electronic settings/restrictions such as lower line pressure and enhanced torque management/restriction active to protect the components from hardware failure.
The unit may likely end up shifting slower because of it. TapShift is really just for looks when it comes to the 4T65, not very useful especially on a factory transmission/valve body.

I went through again looking at factory cal's i see very similar tables between d and tapshift shift pressures tables and modifiers.however they vary through 04-08 calibrations from being better in D and some edge out in Tapshift. All barley noticeable.
My point is TAP shift on a factory cal cant hurt your performance enough to make that kind of statement. it seems to me there were other issues at play.
The way i have my setup is in tapshift mode zero tourqe mangment .100 on shift times line pressure increased 25% from regular shift pressures etc..... essentially "performance mode".

Common sense > any thread.

You can't shift faster than a computer, nor get the exact same shift points each time either.

Only thing Tap Shift is good for is holding a gear when: roll racing or tracking the car.

Tap shift does exactly that holds the gear as long ad I need it to do. It all depends on your cars setup. It has nothing to do with shift times its about keeping the power band and shift point where I want them instead of programmed logic doing the job. And if your car is tuned tap shift is a better solution then drive.

You get some black and white hard evidence on paper...such as...quicker times at the drag strip.

I already admitted to it being worthwhile if you autocross the car...I'm just willing to bet you can't go really any faster in the quarter with it, that's all.

Mine did not run any better with tapshift at the 1/8th mile, and mine is tuned. I think its only beneficial in a roll race/autocross and if you know what your doing, from a dig i think its pointless to make a difference

That's what I do, use it for holding a gear, then back into D.
