Well, I didnt know you would be running a MAP sensor, But there is still a problem, unless you tweek the fuel curve with a chip or a ARC2 setup the DME only has the NA fuel/ignition maps to look at so it will see what the MAP sensor is telling it and go to the closes map it has to try and compensate. This is the reason why Speed force racing includes what I think is the ARC2 so you can trick the DME to putting in more fuel. Im not sure what setup you are running, If it came with a MAP sensor then Im sure they gave you the proper tools to tune with. Im talking more along the lines of someone just bolting on a supercharger and thinking the DME knows whats happening. The stock DME has no way to know what boost is or how to deal with it, Infact the stock NA DME has a hard time dealing with the extra air from a MAF setup. Thats why there are signal massagers like the ARC2, Also I know that GURU RACING has some sweet MAP and MAF setups that would be great to use if your making your own SC system.
