Actually I think you will probably still run into an issue as the consult connector is unusual and most workshops won't have that available (everything modern is OBD). It might require a trip to a friendly nissan dealer who does have the right connector (but may not be interested in helping). Alternative is remove the airbag globe and disconnect the airbag computer, if that is legal

AFM is undoubtedly the best way to do things for an OEM, with driveability and emissions very high up in the list of priorities. But as Murray said above, they start to become problematic for modifiers. BOVs are a particular pain point.

It doesn't get tuned to handle the BOV as such, with an aftermarket ECU, you can use a MAP sensor instead of the MAF sensor. In short, the MAP sensor doesn't care about your atmo venting BOV and your mixtures will remain correct. An aftermarket ECU could choose to use a MAF sensor, but not many people do. I haven't used a MAF sensor in something like 20 years. They are a pain in the arse to mount correctly so that the air flows through the way the sensor wants it to (in your now custom intake to suit your bigger turbo etc), they are a restriction in the intake, they have limitations in the volume of air they can accurately measure, you can't use an atmo BOV as you've discovered, etc. -
yep, looks like the wiring guide has me wiring white to trigger 2 and black to 12v (on 34 wiring), even if i went off the 32 wiring, the sensor is still wrong isnt it? white to ground, black to trig 1? I'm assuming black is ground and white needs to go to trig 1?

So with an aftermarket ECU it gets tuned to handle the BOV? and why doesn't an aftermarket ECU use the MAF sensor? Do they all not use the MAF? Do they just have everything programmed into the ECU?
