GTM Racelogic Traction control Review

Might be a dumb question, but whats flat foot shifting?

Mike@GTM

Flat foot shifting is keeping your right foot flat to the floorboard on the gas pedal while shifting without using the clutch.

The traction control system has the ability to cut power to the engine just enough to unload the dog gears in the transmission so you can engage the next gear instead of using the clutch to unload the dog gears.

I believe you are wrong. Flat foot shifting is not lifting your foot off the throttle but still using the clutch to switch gears just as you would. With the RLTC it kicks in a rev limiter that you set that is tripped when you press the clutch allowing you to hold the throttle at 100% and not bounce off the rev limiter.

Since you never let off the throttle you do not bleed off boost which according to RL can shave 0.10s off each shift.

I believe this is correct. Switchin gears without using clutch is power shifting. Something I've seen done but would never do to my own car.

Although quite expensive it seems it gets the job done with traction problems with this car and big power and having launch control would be great. Gonna have to get it down the road!

that's how the no lift shift worked on the Supercharged Cobalt.

I stand corrected. I was thinking of the FR-S/BRZ version of flat foot shifting via Ecutek software that does precisely what I described. You are correct, the Racelogic doesn't have an input for a gearshift sensor to accomplish true flat-foot shifting (no clutch).
