agreed. but that is only a baseline. you are going to need to dyno tune that thing to get everything right. the S-AFC does not know the actual response curve of the MAFS, it only multiplies by a set percentage based on maximum airflow of the sensor. this is a common misconception for most people. they hthink that the S-AFC is will exactly compensate for a different MAF...it will not, it simply applies a percentage change to the reading of incomeing voltage from the MAF. for Z32 Maf on S13 SR it multiplies the incoming voltage by roughly 2.05... yet the 2 MAFS have different response curves so things dont work out exactly correct.
Launch can attest to that. we installed a Z32 MAF on his car and we had to do alot of tuning...even on stock injectors, to get the AFR's where they needed to be.
Definitely need to put that thing on the dyno. Big bonus here not only in getting things straightened out so you don't blow the thing up but also your gonna see some HP gains aswell.
