I have had loads of problems trying to map my car using a map sensor. It is a homemade ecu so no help mapping.
I was wondering if anyone knows where I can find a maf sensor (either an aftermarket or a normal car type) with the calibration data for it (flow verses output voltage).
I have a wideband sensor but it is of limited use as the map value and af dont match up (af sesnor will always be a few seconds behind map value)

Thanks
Darren
