You could always just use a MBC and mechanical boost gauge. That's what I do on my LNF and I still have stock 2 bar map sensors.

the problem is I only have 1 iat so I have to run a mass airflow its a 2.2 with a m62 blower on it and we are only able to tune it on a 1 bar with hp tuners it doesn't support 2 bar or 3 bar so were stuck

maf tune

ezjarecki

I believe the maf is maxing out if that makes sense right now? bc I still have it now could that be correct?

its scaled differently.

im kinda confused sorry I know it runs off of frequency right? it keeps clipping the maf and throwing codes

I got maf frequency too high also. Just turned that code off. You scale the maf then according to fuel trims i think

you can run and tune a 3 bar map on these cars because i did it on my car with a 3 bar but did a maf only tune no ve table. and you shouldnt be maxing the maf out on a m62 i had a bnr 2871r on 25 psi and never maxed my maf out
