I am trying a new perfect power SMT7 piggy back, and having some ECU pinout problems. I have the pinout from RRE website, and it isnt correct as far as I know. The Shop trying to install it has a few questions about the Evo pinout. This is on a 2005 Evo MR. Does anyone have the voltages for the ECU? Wiring diagram of the air flow meter? Dealer pinout of a 05 MR? How many teeth on the crank sensor? Ingnition pattern on the crank 60-2? And is there any difference from the Evo 8 to the MR on the ECU pinout. We are wondering if my car has an Evo 9 ECU. If maybe mid year change is possible. Thanks for all of your input.

 

The '03-'05 have the same 4 plug ECU. The diagram on RRE's website is correct for all models except the EVO 9. The EVO 9 has a 3 plug ECU.

 

don't think the 05 could be the same

 

It's the same. ACD uses a seperate ECU.

This might help (03-05 EVO):

 

Thanks. Does anyone have any voltage info? Crank signal?

 

I did a search, so don't complain about "thread from the dead".

There are at least a few differences between the 03 and 05 ECU pintouts. For example the 03 ECU has inputs for the intercooler spray switch (pin 44 and pin 57) to the ECU and output from the ECU to the dash light (pin 35) indicating that the intercooler sprayer is spraying.

So, since we have established that they are NOT identical, does anyone have the pinout diagram for the 05 ECU?

Bump... I'd like to see this as well

 

03-05 evo ECU wiring is the same. trust me the RRE wiring diagram is correct unless your shop is looking at the connector at wrong angle. why are you installing that on your evo anyway ??

 

So are we to assume then that certain pins (such as intercooler spray) on the 03-04's is just a dead pin on the 05's? I'm certainly not doubting RRE or anyone here for that matter I think most people just want some sort of final verification or 05 specific ecu pinout.

 

yes, i have install over 26 SAFC from 03-06 evos. i can assure the 03-05 are the same wiring diagram. the biggest mistake people make is taping the wrong wire or not fully connected on there. I would solder it. half of the time they don't even read the diagram correctly.

 

Sounds good then...

 

feel free to pm me on any wiring into the harness or patch harness. i will tell you exactly what wires is what
