Special Thanks: Tephra, celica2evo, & my wife for ****ting a brick!

• 0.1" female connectors (Need at LEAST 15)
• Heat shrink tubing or electrical tape

Tools Required

• Brick (aka ECU)
• Tactrix Cable
• Power Supply
• Wire Cutters

• Heat Shrink Gun or Small Lighter (optional)

Recommended Number of People[/LIST][*]1 (+1 to taunt you incessantly about how the Evo is supposed to be a tuner friendly car…)[/LIST]
Difficulty

• 3 (10 if you drink a beer for every connector you make)

Time to complete

• 30-60 minutes

Step by Step Instructions

1. **** a brick.
   
   
   
2. Be a real man and make a pile of them!
   
   
   
3. Correct your grammar. ****, a brick! (If you don't get this, stop here, you can't handle this.)
   
   
   
4. Create a group of wires to power the ECU
   ECU Pins:
   71 -> GROUND
   82 -> +12V
   92 -> +12V
   104 -> +12V
   
   
   
5. Create a group of wires to power the ODBII
   OBDII Pins:
   4 -> GROUND
   5 -> GROUND
   16 -> +12V
   
   
   
6. Create a group of wires to connect the ECU to OBDII
   ECU to OBDII Pins:
   ECU 80 -> OBD 7
   ECU 90 -> OBD 6
   ECU 91 -> OBD 14
   ECU 103 -> OBD 12
   
   
   
7. Connect the wires to the appropriate pins
   
   
   
8. Hook it up to a 12V Power Supply.
   
   
   
9. Choose "Alternate flash method" in ECUFlash options.
   
   
   
   
   
10. Load up your “Last Known Good ROM”
    
    
    
11. Flash your Last Known Good ROM - this will take at least a minute.
    
    
    
12. Now deselect "Alternate flash method" in ECUFlash options.
    
    
    
    
    
13. Flash your “Last Known Good ROM” AGAIN (This will configure the ECU properly.)
    
    
    
14. Stick the ECU back in the car - it should work properly!

nice work koroshiya!

 

your little test bench looks like my office at work lol

good job, wanna come to my place and help me with the rest of the entire electrical system ?

 

Haha Hey Jason if I could give you a hand I would. Let me see if I can get through my Chem work then I'll come over and lick wires to find the power for you.

 

Can you use this method to just put the ecu back to stock? I think i have done something terribly wrong and I'm trying to undo any XML mods I did on my laptop that, "of all things" CRASHED a few days ago and I lost all of my modded XMLs. How can you just put my evo x MR back to stock everything?!?

 

good stuff

 

Simply flash a stock ROM back. But the changes are in your ROM, not the XML definitions.

Just Read the ROM off your ECU and get new definitions. Simple. Done.

 

Is this the same for evo 9

 

God bless you !

"The operation completed successfully."

 

I used the how to as well to unbrick my ecu. After I flash in my stock map and load it into the car. The car still has the fans blazing away and all the check lights popping up on the dash. I dont know what to do. The car will also not crank at all. Can somebody help please?
