AFC II for non DSM??

[LightningGSX]

The GM MAFs DSMers use are Hz output just like the OEM karman sensors.I'm not sure if the AFC is capable of the high frequencies GM MAFs output.If you use speed density, which depending on your ECU, is probably just a matter of changing EPROM code, you could use the AFC to alter the 0-5v MAP input like Ecoli said
