Evo 8 ECU in a 2g - Your Visual Guide
By Knochgoon24
Difficulty: 3 out of 5 - Intermediate wiring skills
The difficulty is not from the install. It's from the learning curve on how to actually tune it.
This is a VFAQ on how to do this swap. I'm not responsible for any damage to your car from doing this mod. Do it at your own risk. Also, this was done on an automatic '97. You may find slight differences between this and your car.
Ignore the red electrical tape. That's covering pinholes from removing an SAFC 2.
There are additional steps that need to be taken to swap this into a 95/96. It's basically opposite what the 97+ have to do to run a 95 Ecu. If someone would like to send me the steps (photos a bonus) I'll add it with credit to you.
You'll need:
Evo 8 ECU
Openport/Tactrix 1.3 or 2.0 cable
male and female crimp/solder connector
Tools you'll need:
10mm socket or wrench
short phillips screwdriver
mini flat screwdriver or paperclip
solderng iron
Stuff you should have already:
Wideband o2 sensor
---------------------------------------------------------------------------------------------------------------
Step 1:
Disconnect your battery.
Turn your boost down. You're installing a completely new computer in your car that isn't tuned for your car. Crawl before you run.
I pulled my MBC out and ran direct WG pressure on my s16g.
Step 2:
Remove your driver and passenger center kick panels.
Step 3:
Unplug the 4 connectors from your ECU. Just squeeze the tab down and pull. I like to start with the bottom one and work my way up.
Step 4:
Remove the 3 screws that hold your ECU in.
(Someone send me a photo.)
You'll also need to remove one screw off your HVAC ducting so that it moves enough to let you pull the ecu out.
Pull the ECU free. Put the HVAC screw back in.
Step 5:
Get oriented. This is the view of the connectors that is used in the two diagrams. Printing the diagrams out is helpful.
Here's a good link to a full list of pins and wire colors on the 2g. Very helpful. http://www.dsmtuners.com/forums/articles-tuning-ecu/281763-2g-turbo-ecu-pinout-w-wire-colors.html -Thanks Eric (turbosax2)
Step 6:
Our first pin to remove will be pin #58, the tach pin. It isn't used after the swap, so it makes a good pin to practice on. If you damage it while getting it out, don't worry. But it's best to practice trying to remove them undamaged.
It's the white wire here.
To remove a pin, first pop up the white lock on the connector. I just used a mini screw driver to get under the small tabs and pop it up. (First photo is a different connector - I know )
Now take that small screwdriver, a paperclip, or some other small implement, and push down near the front of the pin. It may help to push the wire into the connector as you push down on this. When you pull the pin out, it comes out freely with little or no resistance. DO NOT PULL HARD!
The part that's shiny is what you want to press down on.
(I'll try to get a better image later)
The pin itself looks like this. You're pressing down on the one tab. (Facing left)
