Could someone verify this pinout diagram for me.....

I'm using Ian C's pinout diagram from the following thread....

 

http://www.mkivsupra.net/vbb/showthread.php?35919-ECU-Pinouts

 

The following picture shows the pin I am querying....

I believe this is the air intake temperature pin. Am I right in saying that this won't be used with a single install? Is there an air temperature sensor with the stock JSpec setup? Just wondering if this is a UK only thing.

 

Thanks :)

Just realised something. I'm holding the loom, rather than the ECU. Am I right in thinking that the pinout diagram is for the loom.... rather than for the ECU itself. It would make sense for it to be the loom but I don't want to confuse the issue by having to mirror what I'm seeing in the pinout diagram :)

There is an Intake air temp sensor on the stock manifold yes. It's just behind the throttle body on the inside.

 

It's 100% used on a single install.

Pinout diagram is for the ECU yes, imagine you're looking at the ECU side on.

I don't think I've connected it. Got any pictures of it?

Ok that muddies the water slightly then. Are you absolutely categorically sure on this? That would mean that it's definitely not the air intake sensor wire.

I've ran out of inputs and Ryan is adamant that I should have pin 65 spare. I need one more input for the TC switch.

 

I currently have:

 

AN1 - Cam Sensor

AN2 - Crank Sensor

AN3 - Wheel Speed RL

AN4 - Wheel Speed RR

AN5 - I don't seem to have anything here. Could I use this? Says in the pinout that it's vehicle speed?

AN6 - Air Con Switch

AN7 - Wheel Speed FL

AN8 - Wheel Speed FR

AN9 - TPS

AN10 - MAP Sensor

AN11 - Fuel Pressure

AN12 - Oil Pressure

AN13 - Coolant Temp

AN14 - Oil Temp

AN15 - Not set to anything but currently pin 65 going into harness pin 25 as per the pic.

 

Cheers :)

Just went out and had another look at it to source pin 58.

 

First of all, of course that's the ECU pinout. The harness is effectively mimicking the ECU, doh!!

 

Secondly, it appears that pin 58 from the syvecs is going to either pin 1 or pin 2 on the ecu harness (E10). This wouldn't make any sense as pin 1 is for auto and pin 2 isn't for anything. Does that mean that I can use pin 58 for the TC switch and set pin 65 as the IAT? What benefit will I have of using the IAT, the ECU doesn't seem bothered that it's not there at the moment lol.

I think I've sussed it out.

 

Pin 64 is for the IAT, my pin 64 is clear.

Pin 65 is a spare input, my pin 65 is connected to the IAT.

 

Having seen the above pattern it's clear to me that I should use AN14 for the IAT.

 

Pin 58 is the Vehicle Speed Input. I believe this is an Auto characteristic. It goes to either pin 1 or pin 2 on E10. Pin 1 is for Auto and pin 2 is meant to be empty. I'll verify this before doing anything though. Once that's done I'll use pin 58 to connect the TC cal switch and configure AN5 accordingly.

 

That should hopefully sort out my issues :)
