Tuning Question regarding my EJ20 Twin Turbo Build

[mripod64]

Hello all, ive recently joined to ask a couple questions About ecu swapping and tune-ability.

 

i have a JDM EJ20 Twin Turbo with harness and ECU, now Tuning for the E20TT is extremely limited (at least here in the states) so that will make it quite difficult for me to tune the ECU for running 90 octane (That's the highest we have in Alaska) The only company that i found (Enduring Solutions Limited) that can do anything with these engines hasn't responded to my attempts at contacting them.

 

so as it stands my options are

-Meth Kit

-Standalone ECU

 

But then i discovered something while searching for information about standalone ECU's, and i found that a 97-02 Forester SF5 ECU has the exact same plugs as my EJ20TT ECU!

 

So now that youve heard the story, heres the question.

Can i use the Forester SF5 ECU and simply have it tuned to run my engine?

I'll talk to Mike our Tuner and see if we can do anything.

Mike wants to know what year the ECU is from

[mripod64]

Not sure of the exact year, but its from a 3rd gen Legacy B4.

 

ECU numbers are

 

Y9

22611 AG302

A18-000 D3U|0920

unfortunately that ECU is not reflashable

Tuning the ecu is very easy. I have done many of them including the S401.

What is important is the year. 2001-2002/3 is easy tuneable. But I would say to you that rhe single conversion is better, but the engine response would not be the same. Hence why TT owners keep it.

 

PM me if you need any more information.
