Yeah, I did the write-up, and Maf is wrong. I'll talk to Luke about changing it soon.

The blue wire, you'll hook that to the wire coming from the engine, that's in.

The purple wire, you'll hook that to the ECU, that's out.

On the write-up, I had to opposite. And I'm working on possibly correcting the VSS in and out corrections, too.

Sorry.

Be careful not to mix them up, if you wire it up wrong you could blow the chip on your ECU. I wired mine up incorrectly, I had the 5volt from the Ecu going to power, and the 12volt power wire going to the ECU, too much power and it kept blowing my custom chips.

i got the car running last night but the maf isnt connected to the emanage right now because were just bypassing it with the pressure sensor, i have direct controll over injectors which is better then having to controll them through a maf.

Seems you would use the white input to EU and green output to ECU on connector b per hotwire instructions instead of the purple/blue wires at all since that's the karman vortex setup???

When we wire the maf wire up wrongly, it'll just have 0 volts going into the EU and 0 volts conflicting to the possibly 0.9-1.7 volts coming from the Maf. This is not a big deal unless the car has started and reved high enough to send higher voltages into the EU. But even so, it will not fry up any EU chips because EU will detect an error code at this time and stop working.

So either way, it'll not damage the ECU at all.
