| + | **__NOTE__: THE INFORMATION ON THIS PAGE IS DATED. THE INFORMATION BELOW IS BASED ON DOING YOUR OWN WIRE SWAPS USING A PLUG-N-PLAY HARNESS ADAPTER. WE NOW PROVIDE A MODIFICATION SERVICE TO MAKE A 2G ECU PLUG-COMPATIBLE WITH AN EVO8 HARNESS. WHEN USING A 2G ECU THAT'S BEEN MODIFIED LIKE THIS, MUCH OF THE STUFF LISTED BELOW CAN BE IGNORED.** | ||

| This used to be a popular swap for a while back when the EVOs were new. The interest seemed to die down a bit as guys started playing around with ECUFlash and EVOScan. But for some reason, we're getting more and more requests for this information lately. | This used to be a popular swap for a while back when the EVOs were new.

| 37 Cut this wire. It provides the ECU with a power steering pressure switch indication. This is used to raise idle when you turn the steering wheel. But it causes more problems than anything else when running a 2G DSM ECU. Just cut it. It's not needed. I have no dips in idle when turning my steering wheel with this wire cut. | 37 Cut this wire.

Cut pin 1 wire at OBD2 port, do not splice this in. You want the 95 ECU to be the only thing connected to this pin on the OBD2 port. | + | 56 Cut this wire, run a wire from 56 at the 95 ECU to pin 1 at the [[https://www.ecmtuning.com/images/forums/obdiiconnector.gif|OBD2 port in the car]] (note that the image is of the OBD2 connector in the car).

| The EVO ISC motor must provide more airflow per "step" because default operation with a 2G DSM ECU results in idle surges as the car starts to move. You can disable this using the patch listed below (you'll want to grab the moving idle disable file towards the bottom). | The EVO ISC motor must provide more airflow per "step" because default operation with a 2G DSM ECU results in idle surges as the car starts to move.

| You may also find that having the power steering pump signal connected to the ECU can cause crazy ramps up in idle too. To "work around" that, simply disconnect the wire leading to the pressure sensor on the power steering pump. That way the ECU will simply never "see" this signal and won't respond to it. | You may also find that having the power steering pump signal connected to the ECU can cause crazy ramps up in idle too.
