2007 STI stage 2 Flat Foot question

set it to 0 RPM. Also if you're not pressing the gas at the same time as the clutch it shouldn't be doing anything anyway.

It shouldn't affect your regular driving regardless of what RPM is set at. You shouldn't be on the gas while upshifting (clutch depressed) unless you are trying to use FFS. This is the only circumstance where FFS would be active. I think I have mine set at 5k or 5.5k. I think you can go into the AP and press reset ECU and that should keep the flash and all of the data and blast FFS and Launch Control settings. It also clears all the CELs and clears out the Learned Knock table. Not a bad idea to do once in a while.

Just to add to this- whenever I would reset my ECU, I would have to up the FFS to 7800+rpm (I never went that high) otherwise the car would act pissy. It would hesitate before taking off between shifts. I was not on the gas/clutch at the same time, but it was still interfering.

I set mine to 7200 rpm.

I have had issues while driving spirited. I rest my foot on the clutch between shifts. Sometimes this is enough to trigger the clutch switch, and FFS. This makes the car jerk violently, so I have set it high enough to stay off. I do not set it too high over the rpm limit just in case it gets activated.

Honestly not sure if the normal rev limiter will kick in over the FFS limiter. I believe it does, but not taking that chance.

The normal rev limiter will kick in. This is what solved my problem. It may be different for others. YMMV

I have mine set to 5,800 and it doesn't affect normal driving.

i think it depends on the version software/firmware your running in your AP... bc i have seen it set any way but no clutch switch, no issues... also seen it do like some of you said above, where it would blip the ignition advance or throttle slightly just when shifting from WOT/high RPM no two at the same time. my personal car has no issues like that tho, and i think its still enabled to 7100, it was at least.

btw, the clutch switch is nearly impossible to get any input unless the pedal is almost to the floor... they arent variable sensors like a throttle position sensor, they are on/off and dont engage until on the floor for safety of you and the drivetrain.

Yes the switch is at the top of travel, not at the bottom. At least according to Cobb. I will see if I can find the post.

Found the thread........ http://www.iwsti.com/forums/ecu-tun...hifting-cause-engine-damage-when-not-use.html

its actually both... i just went and looked at my STi. there is a switch that is in the closed position when the pedal is all the way up, untouched. then above that, there is a second switch that is in the open position when the clutch is up, untouched. however, resting your foot will not open the first switch or close the second switch until you have it pressed down about an inch... then both switches are open, and as you get towards the floor the second switch closes.

so if the FFS uses the first switch from closed-open to "start" the FFS process then resting your foot on the clutch enough to press down the pedal an inch or so could screw with the FFS... best to just disable it if you heavily rest on the clutch IMO.
