thats not going to work with the stock ecm. a cobra maf requires a subtractor program to work with a nissan since it uses a wider voltage range. The only way to know if your proplems are maf related is to swap maf's and see if the problem goes away or data logging the maf signal to see it you are maxing out the signal at wot. since the stock maf is 70mm I would think it should be able to meter up to at least 350whp but I have not seen the voltage readings off a turbo car to gauge where the maf maxes out.RedVRy81 said:hmmm maybe i should try a different maf? cobra?

The Cobra MAF only requires the subtractor program if you want to use it to make over 350 whp or so. JWT can program for the Cobra MAF with or without the subtractor circuit, depending on how much power you want.cortrim1 said:thats not going to work with the stock ecm. a cobra maf requires a subtractor program to work with a nissan since it uses a wider voltage range.

but this will not work with out a reprogrammed ecm and thats not availible for the qr25de.NiceGuy said:The Cobra MAF only requires the subtractor program if you want to use it to make over 350 whp or so.
