I dyno'd a 240z with a l28et swap yesterday. It's got a z31 ecu swap as well and developed 260hp at 5500rpm or so with the top maf voltage being 5.9vdc. This car didn't have a nistune ecu so I can't say for sure where the vq map was being accessed, but a good guess would be that the stock maf is good to around 400whp. Matt any thoughts on where the data is being accessed at this voltage?
My delay in reply usually means I dont know. But to answer this, you would need to look at the VQ map voltage levels translation to know for sure plus 1500mv
The VQ maptrace seems to be accurate to voltage levels we are reading based from hardware maptrace feedback
