Thanks Wreckleford and grants for all the info in this thread.

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 :D

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 :cool:

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 ;)

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).

New contacts(terminals) available :D

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 :eek: :moon: :crackup: 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.

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 ?

no it aint as on the 7 ecu the SAS is pin 53, ;)

evo 4,5,6 didn't have egr

Ok a little update about my questions above.

Wreckleford sent me a PM, as he has run out of posts for this month, but asked me to post the info here.

If you swap over the SAS wire, you will get a check engine light for the EGR code, which is why I don't recommend doing it. The EGR and SAS solenoids are the same, and the SAS is not essential anyway.

BTW - Ralliart 7 ECUs don't have immobilizers. Also, from what I have seen any 8 ECU will require the 8 and 22 to be swapped, even if the immobilizer is bypassed.

Pin 91 can be left to ground without any adverse effects I am aware of. The ECU grounds it anyway when the water spray is in automatic mode.

usdm e8 ecu in an JDM e6 RS

i've pm'd a few of you in this thread, but i'm hoping now to get some dialogue going about the possibility of this working.

usdm e8 pinout diagram (i don't know how correct it is and they dont specify which is hi and lo ac fan).

http://www.evomoto.com/tech_info.php?tPath=3_5&tech_id=19

if i follow Wreckleford's instructions on how to get the e6 fans going on the e7, and assume that pin 31 is ac/hi and pin 32 is ac/low on the e8 then i would:

disconnect the idle switch wire 87
repin wire 34 into 31
repin wire 32 into 34
disconnect 20 and reconnect to 31
disconnect 21 and reconnect to 34

what will need to be done to the following that exist neither on the e6 or e7? someone suggested you might be able reflash an e7 rom over an e8, but i don't know.

75 REAR LAMBDA - which as far as i know requires and combination of rom and hardware fix
43 CLUTCH POS SWITCH INP
46 FUEL LEVEL INP
55 EVAP VENT SOLENOID
57 FMIC SPRAYER
61 FUEL TANK DIFF PRES SNSR
73 MAN DIFF PRESS SNSR
74 SUB FUEL SNSR
77 FUEL TEMP SNSR

side by side pinout comparison
