This is one of the most interesting solves in a while. Just last weekend, my wife re-told the story of how her dad would call her out for resting her foot on the clutch.

10/10 thread.

good steve finds always a way, he s the best:)

i got confused by the fact his. log didn t have all the normal values logged by default by ecutek, but now we know it s kind of easier to spot from the afr target he gets too

steve we love. you

+1 Steve. Even took the time to mostly spell-check. Maybe someone hacked his account. ;)

I was thinking that it would be interesting to log everything while playing with the switch, but it already makes perfect sense in hindsight.

yes when you log clutch switch (it s not default value) it shows immediately as clutch switch value would jump to 1 when it starts the bog

Finally putting this one to bed. PTuning sent me an update which turned off ffs and P0420. I can drive my car with my foot touching (but not riding, since I don't want to piss off @ultramoon's father in law)) the clutch before I shift. What a joy.

As per @steve99, I will have the tuner disable FFS since these transmissions would probably go bang after 2-3 FFS's. Thanks again.


the standard ecutek FFS setup is quite harsh as it actually hold the rpm 200 rpm above the rpm clutch was pressed. for smooth shifts you want to have the rpm hold between 200 less to 1200 rpm less than when clutch pressed ( depending on the rpm of shift, i calculated this of the average gear ratio change and this produces very smooth shifts like an auto actually smoother than you can do yourself.

On the dyno, it actually looks fairly smooth.

That's terrible! Why even bother having the feature?

tomm.brz 06-07-2022 07:23 PM

that' s terrible for the clutch and transmission. but allows for the quickest shift, as it "pushes" the car forward as you change gears


Wouldn t use it anyway. i put the rpm lower always like steve said

I have had the same problem with my car. Sudden cut of between 5 and 7k rpm about 5 times now. I went out driving today and tested the cruise. It took an unbelievably baby push on the clutch to turn it off. I usually run my car with the tune that includes racerom features. I like the auto blip.

So I tried to replicate the cutoff. Couldn't do it. Now going to run the tune without racerom and see if it happens again.
