NB MAF voltage vs. RPM and MAP
 

Stock 2000 MAF voltage vs. RPM and MAP curve fit function.

I'm gonna upload this here for posterity. Not included is the MAF voltage when the engine is stalled.

The function in the file uses RPM and MAP in kPa.

This is awesome!

This should be close enough to get a lot of good things started, but shouldn't it technically have a temperature factor? What conditions were present when the data was logged? Was it truly a completely stock vehicle from airbox to exhaust tip?

Thanks again.

Jason, is this the whole equation? It looks truncated and when used in excel to create a 3D map, it diverges from your values as RPM and MAP increase...

PS. Newer versions of Mathcad do not support the viewer. And the 30 day trial requires a huge pain in the ass and jumping through hoops to register.

nevermind... it IS truncated. I already had jumped through some of the hoops and just regged my 30 day trial.

at the end of that should be:

+ 2.085015*10^-6 * RPM * MAP
