How to filter load when imrc is open/close

[Pappacosworth]

I'm trying to make histograms, so I could tune failed maf table. I can't find suitable parameter for filter so I could populate table for both situations: imrc open or closed. If someone has made them, could you help. I have histogram but it has both values mixed in on histogram.

Car is Mustang 2006 GT, rather stock, long headers and rear gears.

Post a log and tune and I will make histograms for you.

you will have to apply a few conditions as IMRC opens based on varying RPM and load.

So what I did was find an equation that fits your IMRC open VS RPM table values by putting them into this website. http://www.mathportal.org/calculator...calculator.php I used x as load and Y as RPM. Pictured below is the result. Its not exact but its close enough and gives you something to use in a filter.

The filter will then look like whats pictured below. Just replace MAF with inffered MAP and reverse the greater than/ less than sign to filter out data when IMRC is open or closed.

IMRC Closed = RPM < -2574 * LOAD(as number) + 3616
IMRC Open = RPM > -2574 * LOAD(as number) + 3616

Thanks! Now I understand this better and maybe next time I can figure it out myself.

I updated failed maf tables, there was noticeable effect even values were rather different. Both trims were ok after two trips. But car works fine and stays in commanded a/f ratio.
