With multiple devices on the bus make sure all are on separate IDs and are all operating at the same speed. The Dash has the option of having a terminating resistor in circuit or not. Make sure dash is on the end of the bus and terminating resistor is on and no other devices have a terminating resistor.

Pico Scope work well and we have sold these in the past. But there are many others out now. Others might pitch in with what they have found good.

You are going to have to get a scope on to the trigger signals to see what is going on other wise we are just guessing.

You could just had to the base maps folder in the PC link download and select the GTS base map as this will be MAP based for a starting point.

For that application the map will be relatively good as we had a car for full testing (assuming stock STi) However it should not be treated as tuned. The Skyline was supplied from a tuner so would only be considered a start up map.

Lowest is 0.2 Best bet will be to scope the signal to get the actual voltage and would also confirm the polarity is correct. If you keep the sensor to tooth gap as close as possible this will help keep the voltage up.

If you are not seeing the drives pull to ground in the test mode then that points heavily to a damaged Aux driver chip. Suspect this will need to come in for repair

No either will be fine. If one is happening close to when the gap goes past the crank sensor this would be the best one to remove.

CAN will be on a different connector it is not available on the XS connectors that would have been used for the ethanol sensor

The correct option where the stock crank trigger has been changed is to remove one of the cam teeth to leave only one. You will then be able to use the trig 2 set as Cam x1

Pot will need a 5V supply and a ground and then the signal will be wired back to a AN volt on the ECU. (Just like wiring in a TPS sensor)

Should be in the next day or two.

It effectively resets at each engine start. I would check the wiring to and from the sensor and the ground for the unit.

The 3SGE VVTi might work as this is a 36-2 on the crank and then 3 teeth on cam (4-1)

As much as the above suggestions will work there is still an issue in the wiring that should really be resolved as it effects more than just the ECU. With the likes of the fuel pump being supplied from this feed you will also have a slow fuel pump and then in turn low flow. There is every chance the factory is allowing the car to run and there is enough flow for a stock application. But start pushing things and there is every chance you will find other issues. My advice is diagnose and sort the issue properly rather than looking for a work around.

It would be assigned as a GP input. You can then label as Anti lag switch.

The MAP sensor on the late V6 wrx changed to what we consider the V7 map sensor. Other thing would be check the RPM reading is stable at around 200 on crank. If its jumpy or way off then it could be the dip switch settings on the board (for the trigger inputs) need to be changed to the alternative positions.

Hi all We have found that the 5.6.6 software is not happy connecting to firmware versions prior to 5.6.5. and the tune can be lost if not saved prior in PC link 5.6.5. We have decided to remove this update from the website for the time until we can resolve the issue.

The CAS wiring should not have any effect on the dropped connection but will impact the lack of RPM if incorrect.

Check your timing offset you might be 360 out and firing on the exhaust stroke.

The fact you have a reading of 140kpa would indicate its likely a 2 bar sensor you have got not a 3 bar. Assuming it is not in a fault mode and that is your fault value

I suspect that is a typo in the manual I would also expect them to be a 12V power supply as per factory.

The AC request is a 12 volt signal so the pullup should be set to off. Can you confirm your jumper settings and that the jumpers are making contact (maybe slide them on and off a couple of times) Di3 / AC request is via these.

Im assuming you had the engine running and there is only one output assigned as Engine Fan 1?
