i-ACC Cruise control problem under 70kph

Post by AaronEG » Tue Apr 16, 2019 2:01 am

Hey Guys,

i have flashed a customer FK7 1.5 Turbo European model with i-ACC
tune is perfect and working great, the only thing since i tuned the car,

the adaptive cruise control isnt working right under 70kph or in in the lower rpm
it starts to accelerate and decelerate slightly above and below 70kph so it has got a bigger hysterese or something,
if you use it at 100kp or 60mph evrything works flawless

maybe somebody has had the same issue, or a tip what it could be.

Regards Aaron

Make sure overrun throttle (rev hang) is enabled for cruise control.

any other ideas ? maybe its a firmware issue ?
or is it the increased throttle response maybe ? so that the PID algorythim of the cruise control isn't working like it should ?

You have to put tables back to stock and then narrow down the cause. We have not seem problems as long as rev hang is enabled.

I had the same issue with my 2017 1.5T Sport Plus (FK7).
Flashed in a new tune with rev hang enabled, and everything works fine.

Also, when you flash a tune with rev hang disabled you get an LKAS error on the first start.
With rev hang enabled you dont get any errors.

@Hondata, Maybe you should make a note on the rev hang option in the program, that it must be enabled if you want the adaptive cruise control to work.
