Re: Tuning Problems.

Someone else told me that despite the voltage almost maxing out , since the counts value stays below 1023 then the MAF probably isn't pegged. My tuner went ahead and sent me a new tune with the MAFia set on 4, but without some definative explaination as to why it is pegging on the number 3 setting, I am a little nervous changing anything on the intake. I don't want to blow it up. Plus I don't know if I need to take the car directly to the dyno again before getting into boost with this new tune.


According to James @ RWTD the calculation to go from counts displayed in the CMR_dat software that I am using to volts is

(Counts * 5) / 1024 = Voltage

(Go here to see his explaination: http://www.modularfords.com/forums/2...a-25368-3.html)

If I use this I end up with 4.14 volts @ 4529 RPM and 4.61 volts @ 6000 RPM.


Why is this different from what the Predator showed and which to I believe?
