EVO ECU Pinout & Colour Chart - COMPLETED

Hi all. I've collected a few different ECU pinout drawings and wiring codes and combined the best descriptions into one. A couple were sourced from forums, one was a 3-page scan of a Mitsubishi document, and a couple were sourced from cross referencing to the 4G93 diagrams to see if the pinout had the same use or a better description. Nearly all of the info when put side between each of them matched up or made better sense which helped confirm each pinout. Basically I was comparing and confirming each pinout and entered the data into an excel spreadsheet (I sort of copied a layout someone did a while ago which I thought was a good idea but I added better descriptions to it).

Cheers. That's one of the ones I used to compare with and adopted his style because it is set out well. I have added to his with more info and I'll go through that site and update any extra stuff found out along the way Cool

. This is the original one from that site Smile

Cool thanks mate, from that site have since discovered these:

Pin 3 = RADIATOR FAN RELAY (A/C LOW)
Pin 16 = RADIATOR FAN RELAY (A/C HIGH)
Pin 41 = NEGATIVE TRIGGER FOR TURBO SPOOL ICON IN EVO 1/ GSR GAUGES CLUSTERS

Keep 'em coming boys Cool

Another source that might have the information, is somebody that has the Autronic Evo Plug-In ecu manual. I remember seeing the pinout diagrams at my tuners a few weeks ago. Unfortunately I dont have a copy Sad

I've also heard the E4 ecu pinouts are similar to E3. Not sure how true it is. But i know to install an Autronic for an E1-3, you can use their E4 designated model plug-in with a few plug changes.

here's another ECU tech referance for you rob

Pic I found along the way, looks like yours is WAY better tho!

Liberoz link is for a later model EVO which has 4 x ECU plugs, not 3 like in the GSR/EVO I-III. However some of the items that are located in the same pinout position add to a better description of the same pinout on the EVO I-III so I'll update the ECU drawing again Smile

i.e. Ignition signal amplifier A (transister) = now called Ignition Power Transister/Amplifier A for cyclinders 1 & 4 Wink

The other little pic above from Richard shows the wires you need to splice to when wiring in an Apexi AVC-R into a CC GSR/EVO/Libero Wink

used the complete wiring diagram on the weekend!!! THANK YOU VERRY MUCH!!!! Very Happy

Does anyone know the differences between the evo 1-3 ecu wiring and the Aus Spec GSR ecu? Been considering making up my own loom for the climate control.....

Anyone doing any serious work regarding these ECU pinouts (engine converions, different computers, rewiring etc) also needs to know the pinouts of the main relay. It is called the "MFI Relay". It has 2 relays in it, one controling the fuel pump. The other sends power to the sensors, injector resistor, and the ECU. It is important to see a wiring diagram to see how the relay interacts with the ECU, pinouts are not always enough.

On some Mitsubishis, the fuel pump side of the relay is momentarialy powered by the starter signal while cranking. On the Evo I,II,III the starter signal is sent to the ECU. The ECU then decides when to activate the fuel pump relay (and it does this while cranking).

Not all Mitsubishi MFI relays are wired the same. The Evo I is a 8 pin connector and these are the pinouts.

MFI Relay:
1. to fuel pump Black/blue
2. sensor power Red
3. Main power to ECU, pins 12 & 25 on ECU
4. 12V power Black/yellow

5. fuel pump signal, from ECU pin 8
6. power signal, from ECU pin 38
7. Ignition and also pin 62 on ECU
8. 12V power Black/yellow

Can you list the corresponding colours on the MFI (engine control relay) plug for us please? Smile

I've never had any issues with incompatible wiring of relays doing 4G93T/4G63T conversions to GLXi's or GSR's but it would be good to have the pinouts as reference. I've even put Proton Gti/M21 engines into GLXi's using the Proton ECU and engine loom and just used their twin relay setups which was virtually plug and play as well. Pretty easy to convert across the board if you get the corresponding relay with the engine loom. Gotta love Mitsus Twisted Evil

I just put up some colours there. Where the ECU pin is listed, it is the same wire and colour as at the ECU, (or MFI as Mitsubishi call it).
