No DI 3 - Subaru V10, Ethanol Sensor hook up

[Levon Luther]

Am I reading this right - there is no DI3 on the pin out list, even though there is Air Conditioning Request from it? I have a plug in V10 board

Trying to hook up my Ethanol sensor to something, and I dont see anything I can get rid of for sure. Maybe Simon or someone from link can advise what the three bolded items are and maybe correct some of my thinking if I am incorrect.

DI#1 Speed - is this needed?

DI#2 VVT Position - AVCS Cams

DI#3 Air Conditioning Request. This is what I want to use. What pin is it on the Subaru Wiring loom??

DI#4 Clutch Switch - Needed to start the car

DI#5 Brake Switch - Is this needed?

DI#6 Digital Knock Feed Back - Using Knockblock G4

DI#7 Cruise Switch - Only DI 1-6 allow the E85 Sensor; Not needed.

DI#8 Start Position - Needed.

DI#9 Neutral / Park - Not needed in my opinion

DI#10 Cruise Switch - Not Needed

Ideally, I'd like to just delete the speed DI#1 or DI#5 and run my ethanol sensor to it. I am assuming that wont work.

My Idea is that I could move my Brake switch from DI#5 to DI#7 / DI#9 / DI#10, and then wire up my ethanol sensor to DI#5. This isn't the ideal situation because I don't want to swap wires for no reason when there should be a wire somewhere. I was trying to track down where this DI#3 might be located on the pin out.

I appreciate any help offered!

Do you have the 04-06 board or the 06-07?

On the later ecu the AC request can be on one of two pins depending on ECU jumper configuration.

[Levon Luther]

I have the 04-06. 04 Specifically. I noticed that on the late model 06 and 07s that it was there, but I didn't see it on mine, yet there is a Air Con Request as a digital input.

[Simon]

It will be on D16 or 17 depending on jumper locations.

If you wanted to use other Di inputs Di5 or 8 would be my picks. Both are not needed for good running of the engine.

[Levon Luther]

10-4. I'll do some investigation to see what I can come up with. DI#8 wont work because it isn't DI#1-6 which are the only ones that the ethanol sensor is 'allowed' to go onto. Thanks Simon!

[Levon Luther]

I'm not sure how you come up with that, but at this point I dont care

D16 - Winning Ticket

D17 - Sorry try again next time.

Many thanks Simon

It depends on the model as to what each pin does on some models the functions are reversed.

[Levon Luther]

I checked it with that service manual and traced out the wire, I'm pretty confident it will work . The other wire went to a relay and the color didn't match per my 04 STi manual.

I'll hope for the best tomorrow. I  am planning on firing it up.

[Levon Luther]

I just want to report back that pin D16 did work flawlessly. I have 9% ethanol in my tank right now.

Thanks Simon

Another Question some what relating to the DIs on the Link platform

I am trying to setup ECU logging, I can use either 'Subaru Cruise switch B'  or ' Cruise Switch' Problem is I dont know which way is which.. The lever goes up,down,in, and there is a button on the end. ... I'm leaning towards cruise switch is the button on the end, but I dont know this to be certain. 

Any help appreciated.

[Simon]

Only advise I can suggest is to set the DI you want to us to a GP input and then try the switches with pull up off. If no action at all try again with pull up on.

[Levon Luther]

Thanks. Another user on the subaru forums suggested I open the status tab to see what lever action activated which DI.

Appreciate it Simon
