Re: Map output offset

Oh it's already ugly. I stayed up all night making a new map but; I've yet to try it. Basically I just made new pressure intervals with the 12 wide interpolated version of my original 8 columns at the bottom, used the the remaining top 4 rows for boost figures, and made sure the 70 kPa A fell where ...

Re: Map output offset

I'm a victim of my own ignorance. This evening I charted the voltages at 10KPa increments on the bench (picked off R2), compared them with calculated values and was only about 100 to 170mv off in each case. Then I searched and found a chart that equated "Hg vacuum to kPa. I saw then that I've been ...

Re: Map output offset

Just took the ECM out of the case and looked. The MAP sensor does have MPX4250 printed on it but; with the suffix letters AP. I don't see any physical damage, the 6 solder joints look OK, though I have often wondered if the measly 3lbs of boost I was getting before could have done something to it. I ...

Map output offset

I recently upgraded my 16 bit MS (green board) that I've been running since about 02' or 03' with the new 32 bit MS II daughter-board to rid myself of centrifugal advance mechanism issues. I imported my VE table because it worked well enough but; I've also stepped up to an Autometer WB and the IAC ...
