hello there guys i have a mugen ECU. IT take way too much fuel when just crusing. I know they run a closed loop. So with the V-AFC how can i lean it out without killing performance. I know theres 2 setting for throttle settings (wide, Narrow). If i remove fuel out of the Narrow throttle will that fix it. And setting the Narrow throttle in the [TH-Point] for eg if Narr. is set to %20 would the [Narr.Thr] be used from %0-20, or is it from %20 to what the high point is set to (%).

So if TH points are set to %20 for low and %50 for high what % would the Narrow throttle be used %0-20 or %20-%50 thanks again

 

no one here us a V-AFC please help

 

TTT

 

4in 4 out i thought is should be 6in and 6out and what about setting the high and low throttle setting

 

what settings do u change when on the dyno?

wide throttle ?

 

4 in 4 out?!! mine are ay 6&6. oh crap!


but when i tried to mess with it the other night, i changed it to 4 and the car died. whats up with that?

 

You can't change sensor input settings while the car is running. I'm running 6 in 6 out like the manual says. I know it works on 6..6 because if I drop my fuel way low at idle I can make the car want to cut off...

 

ok guys what about the low and hight throttle settings if there set to %10 low and %50 high does that mean narrow throttle is better %0-10 or between %10-50 please guys i need to know this one thanks

 

at those settings, the VAFC will follow the low throttle correction up until 10%, and use the high throttle after 50%. in between, it makes an average between your two curves.
