Overrun Fuel Cut


Recommended Posts

Hi Guys,

I've bought a vi-pec powered evo 6 that had been previously mapped. I've got a couple of running issues that hopefully you can help sort out (or correct me!) before I take it back having made other minor engine changes?

First simple question is that the stock mapped evo 6 would have the overrun fuel cut enabled but this car has turned up with it switched off. So on the overrun I am getting a few pops/bangs and of course using more fuel. Given the car has anti-lag and launch enabled via a switch and throttle has the tuner turned it off for this reason? Any other reasons why it has to be OFF?

Question the other way...can I have the overrun enabled and have the anti-lag switchable in the same map?

Easy one ;)
