I have now fitted an Evo 7 Ralliart Ecu to my 6 RSII.

As my car is an RSII there was no need to swap pins 8 and 22, not sure if this would need changing over on a GSR or not.

I did as Wreckleford said, and swapped 32 and 34 round, then wired 20 to 32 and 21 to 34, and left 87 disconnected.

All seems to be working as it should, including the fans and aircon systems

P.S don't know if it it is because my car is an RSII but 32 on my car was Blue with Red trace and not Blue with Yellow as in the diagram.

Once again, Thanks Guys for your help

Sounds good

You only need to swap pins 8 and 22 if your car used the factory imobilizer. JDM cars do not use the imobilizer.

With imobilizer
pin8 = A/C compressor
pin22 = fuel pump

Without imobilizer
pin8 = fuel pump
pin22 = A/C compressor

My car is an OZ delivered RSII which had the factory imobilizer so I did have to swap the pins.

Mine is a uk supplied RSII and have no idea if it uses the factory immobiliser or not

It must not use the imobilizer otherwise you would not be able to start the car

Could be right, although it wouldn't start when I had an evo8 Ralliart rom in it.

Have you rewired yours now to get the fans working ?

No not yet but I will do it on the weekend.

Also with the EVO7 ECU it gives us the possiblity (with a bit of wiring) of having the intercooler water spray work in auto

It took me about 20 mins all in, to get it all wired in as it should be, however I will connect it all up 100% when I get a little more time (as in I will solder the connections) for the moment I have used chop blocks just to test it with.

Ok then, tell me about this wiring up the auto ic spray

I have not done this myself yet but basically you just add the EVO7 intercooler spray wiring (including installing the switch).

Well as you and gtpumps had posted on previous pages on this thread that the evo7 ecu would not work on a 6, without the controler used on the evo 7 fans, I didn't want to go to the hasstle of soldering all the wires up nice and neatly, to findout that it didn't work and that you were both right.

Now I know you were both wrong

I will go back and solder the connections up tomorrow.

No need for new terminals, as the 2 wires that needed swapping over had to have 2 other wires attached to them, it was pointless removing the wires from the connector blocks in the end.

So I just cut them pretty high up the loom, and joined them in to chop blocks, Leaving the 3 pins with nothing connected taped up, so that nothing could short out, and cause problems.

Ok you test that bit out first then, and let me know how you get on

Now I have proved (thanks once again to Wreckleford) this methord sorts the fans problem with the 7 ecu on the 6

Ok fair enough.

Yes and thanks to Wreckleford as well.

Oh 1 other thing I noticed is, with the 7 ecu installed, logging with evoscan no longer requires pins 1 and 4 to be shorted out

Just plug the cable in, and it connects

cossie1 · 13-09-2007, 21:58

Looking at the pinouts again, pin 91 on the 6 is ground, and on the 7 it is IC spray manual.

Is it best to disconnect the ground or just leave it as it is ?

And I assume the Secondary Air Solenoid on pin 6 of the E6 is the same thing as the EGR Solenoid on the E7 ?

evo 4,5,6 didn't have egr
