Awesome data. That's some pretty impressive error at low flow rates. The report says that this test was run with a stock airbox. Is that correct? What intake pipe was used?

 

The error numbers aren't really relevant they are based on a generic curve fit equation I used. I have not curve fit the evolution maf yet.

It was flowed with the stock airbox and filter. Things downstream of the maf do not affect the flow readings. the maf and airbox were flowed without the intake tube.

 

Isn't the MAF in the intake tube?

 

I think you guys are both saying the same thing. The MAF is in it's own housing, which happens to be a tube form. However the actual induction tube, the accordian style rubber piece is after the MAF housing.

 

This should be doable if you correct the MAF IAT load modifier to a range that the MAF IAT sensor would actually see. I don't know how the ecu would react to a drastically high MAF IAT. If a DTC threshold exists for MAF IAT it might need to be adjusted or disabled. Someone who actually does dis-assembly could probably find it. Or there is the "try it and find out" methodology.

We do this on n/a Nissans all the time when converting them to forced induction. It works pretty well, other than the ecu not liking some of the really high IAT readings.
