after I increased throttle sensitivity the engine has be revving up to 2000 randomly after I release the throttle completely at low speeds or at idle? is this some new thing I don't understand? does it have to do with the throttle sensitivity mod?

What vehicle are you referring to?

I've noticed this too with my 1.5T civic. I haven't played around with it too much, but any throttle response/sensitivity "stage" above stock results in a weird fluctuating rolling idle (only with cruise MAIN off). I first thought it was specific to my vehicle because it failed a flash right before and maybe got corrupted. I was just relieved to have it fixed by disabling the sensitivity mods that I haven't played around with every combination to see what factor is at fault though.

Attached is a datalog and calibration showing this behaviour.

I can confirm this on my car too. 1.5T CVT.

For all who havent updated yet. Please stay put as this version is bugged

Can you tell us what vehicle and what sensitivity setting you were using.

2018 si. It's worrisome and sometimes dangerous when i'm cruising on first.

Can you tell me the build number of the software?
