Hi all,

I few weeks ago I bought an Apexi AVC-R from a guy here on SN and today I wanted to connect it. The only problem is that the unit does not seem to work. I got all wires setup according to the manual, but the unit did not light up, so I disconnected everything and tried to connect the red wire to + on the battery and the black and green to the - on the battery, still nothing. I would thing that this means that I have been fu.... over? Can anybody confirm?

The unit is connected like this on a phase 1 car:

White: Speed Signal: B95-11
Gray: Throttle: B95-2
Black: Ground: B44-15
Green: Ground: B44-15
Purple: RPM/Injectors: B44-13
Red: Power: B96-12

Any input would be very welcome!! If the unit is broken I need a new ASAP :-(

Kindest regards

Rasmus

 

Does it have any sort of internal fuse?

Maybe its been blown on removal / fitting ?

Not any that I can find :-(

 

I used this ECU pinout:

Can anybody help me confirm the pinout? Please.... ;-)

 

Have you got the specific wiring diagram doc?

No I did not have that. Thanks!

 

there is no fuse in it so if it does not power up it will be fooked the ground however must be conected at 2 different points on the wire (NOT TOGATHER) or it will not work.

 

You have maybe fried it connecting it to the battery like that.

Wouldnt have thought the fella would have sold you a dodgy unit

 

I would not imagine that I would fry it connecting it to the battery, after alle it is supposed to run on 12 volts.

Anyway thanks for the replys. Are there any specific reason why I need to take the ground from two different places one the same wire?

 

the unit needs a very good ground.. hence the two wires.. when installed you should just take a different source for each ground or run a thick wire to the battery.. however you should cause no damage connecting it to the battery.. something wrong with the unit.

or the wiring loom of course..

 

Old post resurrected!

Has anyone had to run a new ground in for their AVC-R, i am getting funny readings on my speed display and wondered if this might be a cause?
