I can't get a meter on the harnesses with them plugged in, I don't want to strip any wires yet
Here's the info had from probing the harnesses, ignition on, MAF's unplugged Pass side Pin 2 (yellow) - 12v Pin 3 (green) - Signal from sensor to dme Pin 4 (teal) - Signal from sensor to dme Pin 5 (pink) - 5v from dme Pin 6 (black) - Ground Driver side Pin 2 (grey) - 12v Pin 3 (yellow) - Signal from sensor to dme Pin 4 (brown) - Signal from sensor to dme Pin 5 (green) - 5v from dme Pin 6 (black) - Ground Last edited by A4RingedONE8T; 07-21-2011 at 01:54 PM. |

Bridged the IAT and MAF +'s, using the signal from the passenger side (lower reading) MAF. First starting the car, the a/f's seem much better than previously, now around 14.6-15.5 sweeping at idle

At this point, why not just go standalone and MAP metering. Then the piping won't matter.

Doesn't UPREV allow you to switch to MAP sensors as opposed to MAF sensors? That would probably be the way to go, especially if you are running higher boost.....
I will be exploring this as well

I had a friend of mine took the ech and somehow rewired the harness to work on the 370z harness but yea that would be a whole other animal to deal with. stillen manifold will end all the bs lol.

MAP sensors run on 0-5v just as the MAF's do. You could most likely remove the MAF's and replace them with MAP on the stock ECU and with the proper tune it should work. You'd have to add a separate IAT sensor (also 0-5v) as well
