Guest Posted January 14, 2018 Share Posted January 14, 2018 (edited) Btw, I think you'll have hard time adapting 2.5i ECU to a turbo engine, and a non-Subaru one no less. Not sure if 2.5i ECU can even be flashed with turbo rom, but even if I doubt all the inputs/outputs are there. Surely the harness won't have turbo bits. I am pretty sure your best bet is a standalone that supports that engine. Edited January 15, 2018 by unclemat Link to comment Share on other sites More sharing options...
Tuning Alliance Posted January 15, 2018 Share Posted January 15, 2018 How are the cam and crank sensors configured? Surprised it runs on that ecu.

dc90ms Posted January 16, 2018 Author Share Posted January 16, 2018 I got it running with the MAF unplugged I think it’s all in the tune now. I messed with the ignition timing btw there are 5 maps for it don’t know why. I used a dsm rom and set it up using that. Like I said it starts now and runs. Think it just needs fine tuned. I have to finish some plumping yet. I logged some time and have a file saved of it. I’m good with fab work and can make things work mechanically but when it come too the tune stuff I’m lost. Basically I had to machine a crank and cam trigger wheel to the 4g63. I can put up more pics of the progress that I did. I know there is a lot of people saying wtf haha.

JmP6889928 Posted January 18, 2018 Share Posted January 18, 2018 Outstanding work. Can't wait to hear how it runs once tuned in. Bummer you couldn't keep the AWD. I think it would be a beast if you could have. Link to comment Share on other sites More sharing options...

Gex Posted January 20, 2018 Share Posted January 20, 2018 (edited) Not so much wtf... More like well done! Interesting swap. Hope that thing doesn’t crank walk it’s way out the front! Best of luck on the rest. Be curious to see how it does on a dyno. What turbo is on it? Edited January 20, 2018 by Gex Link to comment Share on other sites More sharing options...

Carlz0r Posted September 23, 2018 Share Posted September 23, 2018 Interesting swap! I have a bit of experience tuning a 4g63 (though with an AEM EMS). Would love to hear if you've got it up and running yet. Link to comment Share on other sites More sharing options...
