Right this is doing my nut in, could someone please help!?

Have managed to wire in the RPM, Power, Throttle but got too issues.

I can't work out which is the correct MAP sensor wire into the ECU.
And the battery volt meter on the AFC is reading 3.2v and flashing.

I am lost and very confused! LOL!

Would a MAP sensor also been known as a Vacuum sensor?

Yep. Toyota seem to call them all sorts of different things, mine says TURBO PRESSURE SENSOR on it.

Presumably it measures the voltage over the positive and negative wires you have it connected to for power, so I'd double check the positive you've got, and also that you've got a good ground for the negative.

Right i have managed to locate the right wire for the MAP sensor. But once its cut so you get a line in and out for the AFC and you try start the car, it starts up then stalls straight away. :crying:
I can't understand where i am going wrong.

sounds like its got some settings already installed on the neo that are running the wrong signals...

what the output voltage of the neo on the neo output...

Edit: I'm being dense, it'll be pressure.

Wicked, and just to double check, this is the wire I have tapped into!

The green/red one, coming from vacuum sensor.
