Crank Sensor Wiring
Right, looks like our block has the later 12+1 crank trigger wheel, and 4+1 exhaust cam setup with a hall effect sensor, rather than the earlier setup which I already had an ECU setting for, not a massive issue, but I'm just wondering if the early crank sensor wiring is different to the later ones.
The pinout I have for the early ones is:
Pin1: Signal
Pin2: Ground
Pin3: Shield
From left to right looking into the sensor. Now, since the later cars seem to borrowing their trigger wheel and sensor setup from the K20 engines, does the later sensor follow that pinout, or is it the K20's pinout?
Pin1: Signal
Pin2: Ground
Pin3: 12v
Anyone know?

The pinout is different.
The old VR sensors are 2 wire, where the 3rd pin is used to ground the shielding. It's still a 2 wire sensor tho.
The 06+ uses HALL effect sensors as you said. These sensors are almost always 3-wires. Power (+12v), Signal and Ground.
What are you trying to figure out exactly?

Thanks, it should be the second pinout then.
Just checking, I don't have the car to hand at the minute but was trying to write the ECU map whilst I'd got some time spare, unfortunately, the base settings I have for our standalone were for an S2k with VR sensors. The cam sensor isn't an issue as I realised that wasn't a VR when I saw it and tested it, so it's wired as hall effect, but it just struck me that I never looked at the crank sensor, and after finding some info about the trigger wheel changes I assumed the crank would be hall effect as well, since it seems to be the K20 setup that's been fitted on the later/DBW cars.

What ECU are you running?
Correct, the 06+ trigger wheels are the same tooth pattern as most K20's.
If you're using a preset K series trigger profile provided by your standalone, note that the offset will be off. Unplug the injectors, and sync the timing before trying to start the motor.
