Avcr Trouble

[r34unit]

Sup guys
I Installed a apexi avcr boost controller in my r34gtt the other day. And the only way I can get it to work with the revs and speed is like this.

Cylinder 1. Speed 2.

im pretty sure it should be on on cylinder 6.



also when i rev it out to like 7000rpm the avcr will read 8500, 9000 but at idle the controller reads pretty much spot on.

Bad wiring ? Or faulty controller ?

any one else had this kind of issue ?

Cylinder is set to 6 for RBs and 4 for SRs

Speed is set at 2 for Nissan speed sensors

Throttle is set to point up, i.e. when pressed will trigger 5V or so

I would also check if there's a proper +12V feed going into it. I've seen dodgy installations where it's fed off the ECU harness for power.

But when I set it to cylinder 6

The revs are way out !

My power is from ecu, in the manual it say to the pull the power from the ecu

Pull it from the ignition and ground off a clean point.

[r34unit]

Where did you pull a clean ignition from ?

the green wire and the black wire which are grounds, which are also spliced at different points off the ground wire from the ecu should they be done the same way off a clean ground ?

From memory I just used one of the bolts/screws inside the kick panel for my earth.. (green wire) works fine

[Dose Pipe Sutututu]

Under the steering column, so it's a constant +12V / +13.8 when running... as Joey said, just have a clean earth point using a spade terminal to the body of the car.

Where you located? I can have a look for you, if I can fix it a case of beer will do the trick haha

the easiest spot (imo) for the IGN and ACC wires are behind the stereo. very easy to get to.

you would be surprised how many problems can be created by shitty grounding

While sniping the injector single wire make a difference for the rev settings ?
