hi:

WHY my Power FC CELiglt flashes sometimes around 3.8k and mostley at 4k rpm? My tuner assured me that it is NOT engine knock via FC-Commander data, but I am CONCERNED.

Also, my muffler "puff" occasionally after the Power FC upgrade, WHY??? is the fuel too RICH or LEAN or something?

I will share my dyno. soon.

Thanks.

Sounds pretty unusual. Unfortunately not a lot of us are familiar with the Power FC. It isn't available for us in the states yet. There is someone named GOD on this forum that may have some experience.

What do you mean by muffler "puff"?? Is it black smoke coming out of your pipe or what? What code are you pulling?

 

what light are you refering to? b/c i've had my FC for a year now and no idea what light you're talking about, Eric

 

Go into the "Monitor Mode" and monitor your knock, injector duty cycle, and rpms...place it on peak hold...if your knock reads 60 or above, it is indeed your knock sensor warning...

NAB20....he is refering to the Check Engine Light that illuminates when you bounce off the rev limiter, you reach 98% injector duty cycle, or your knock sensor reads 60 or above..

I hope that this helps.
