Power Fc - Fuel Cut And Limiter - Knock

[djvoodoo]

I've recently upgraded the 34R with N1 turbo's and a retune/ EBC. I've noticed the car rev's up so much quicker (i've purposely set the rpm limit to 7900) and I find myself on the limiter a bit more than i used to.

I know that the power fc cuts fuel, not ign, and have noticed the car will knock on the controller (have seen 60/70ish knock)

Apart from getting better at my reaction times when on boost and learning to drive..... Is there any way to combat det on the limiter?

Retard timing?

As it's a soft limiter, it still "bangs" on the limiter, but no flameage etc etc, Could the FC be picking up other noises associated with fuel cut?

water/meth injection? 60/70ish probably isn't too bad but you should have a listen with some knock ears if you can to see if its detonation or just some other driveline noise thats being picked up....

it isnt actually knocking or "pinging". its because your engine is at such a high rev range and when it does the limiter cut your knock sensor will pick it up as "knock"

it will always display high than usual knock readings when on the rev limiter.. its when you pick up high levels of knock when you're climbing the rev range you should be worried.

Set the limit higher and keep an eye on the tacho. Shift at an indicated 7000-7500 rpm and all will be fine.

Good point!
