I believe the MS3 is required. DIYAutotune.com I think is their site

You know... we've been talking about swapping WRX ECUs into EJ251 RS's now for a while. Have any of you guys considered looking at running an EZ30 off something like a EZ36 Tribeca ECU? Then you could just do patch harnesses like we do in the WRX-RS instead of splicing harnesses.

Obviously this isn't really going to solve Vicious's issue right now...

TBW vs Cable to start with. Then there is the problem with immobilizes an lack of tuning. It would be the hardest way around I think.

Will the dude at iWire merge the harnesses for you?

I know they can merge all the ej's together and whatnot, but I don't know if they do h6 stuff.

If your willing to pay at this point, iWire would be a pretty good option.

Keener has said no. Not without the complete car in his hands to work with.

i've already contacted him about this and yes he will but he can't guarantee it's going to be a turn-key affair as he's never done one before. i still need an answer from dyne or 42 autosports or whoever about how the hell they dealt with the problem of TCU/automatic.

my car is also RHD and so is the front clip i got my engine/harness from. there's a link posted a few pages back with a bunch of wiring diagrams but they're all for LHD. i've just printed a couple pages out and spent an hour over in my shed dicking around to discover that the wires aren't the colour stated in the LHD diagrams or stuff isn't in the mirrored place or whatever.

will head into the dealership tomorrow and see if i can purchase the wiring diagrams from them, workshop manual, or something. i've well & truly had enough.

If you end up paying someone to make a harness, I'd be interested in one as well, so maybe we could get a little group buy together.

Why not just contact Phil at Element Tuning and get a Hydra? That's what i am doing for my EZ30R in a 2002 2.5TS. Phil was very confident it would be a no nonsense way to go.

If you go stand alone, will it pass an OBD2 state inspection scan for NY?

new solution: buy the workshop manuals (locally) for both my rs and the donor car, which have the wiring diagrams in them.

take to local wiring dude, drop off with harness, come back with money.

Standalones do not allow ODB2 plug in passing. Read further back about tandem ECUs where a tuneable ECU is wired in that can pass ODB2 and set to force ODB2 readieness and a standalone runs the actual motor.
Basically the short is a WRX or STI ECU is wired in and sent basically just power and can send the signals to the ODB2 port. Set the ECU to say everything is "working" and th standalone sits seperately running the rest of the show.

Have you looked here for wiring diagrams? I thought I got that link from this thread, but I didn't see it when I was looking earlier. Maybe I got it from the big H6 thread over on RS25.com?

there's a few people with successful swaps done. i'm interested to hear how they got around the wiring problem. a couple have talked about tandem ecu's, and a couple haven't. what's the skinny?


i would just hotwire the starter (run a direct line/pushbutton) and then splice in the fuel pump controls but i've since found a vipec v44 for cheap. checking the vipec page http://www.vi-pec.com/ecus/v44 it says support for 4 cylinders or with wasted spark, 8. i have no idea if ez30d are sequential or wasted spark?
What wiring problem? Just merge the harnesses, it'll take you a day or two to properly thin and match lengths then just put them together.

Still not sure why you're making this whole thing so difficult.

because i don't know what i'm doing RE: wiring and all the wiring diagrams are for LHD. i am RHD. if i can get my hands on the right wiring diagrams then i've got a local harness merger-ecu installer-wiring guru lined up to do the merge/install for me. though i keep reading that the lack of AT still wants to play havoc with things?


and what stuff does the ecu take care of aside from running the engine? will i still get the fuel pump priming, heater working, instrument panel etc etc without the stock one?


sigh. i'm great mechanically but wiring i'm hopeless

bro, the diagrams should be the same. The only difference is going to be the shape the harness is made in.

The actual ECU pins and such should all match up. lol, you're adding so much work to something so simple.

You're literally 3hrs from having a running swap. Just splice, dice and put it all back together again, turn the key, jiz, and love the sound of your H6.

yeah man i have no idea what i'm doing with wires

i've spliced in a piggyback ecu but that's about it. that took a couple hours or something and i absolutely hated it. probably one of my most loathed jobs.

i also don't have a wiring diagram for the recipient harness. well, i have the legacy LHD diagrams but i have no idea if the 2.5L section in it is congruent with my impreza RS. i'm going to print it off regardless and give it to the guy doing the merge. if it doesn't match up, i have the RHD ones from australia on the way. either way he can worry about it.

LHD and RHD wiring are not always the same, I cant speak for the early ez30d but i know for a fact that the ez30r RHD edu wiring is diferent than the LHD ecu wiring. I ran into this problem when I did my engine swap, I have the ez30r engine in my forester... The wiring is all US spec legacy bulkhead and engine wiring the ecu is from a uk legacy spec b 3.0. I needed the correct diagrams for the exact car my ecu came from in order to get the wiring right with my US harness.

I didn't know **** when I did my EG33 swap, now I can do a harness from stock to chopped and ready for install in 2 days. Ask Saraphinwolf, I was 100% retarded when i tried my swap.

Now I'm only about 97% retarded.

now all i need is the desire to learn. can't stand wiring.


much easier all round to just drop it off with someone that knows what they're doing. i have plenty of cash to spare at the moment so not like i'll have to live on mac & cheese for the next month or something.

True.

PS, you won't need the MS3 to run your engine, the MS2 can handle 6cylinders in batchfire no problem.
