[2011 USDM STi Denso ECU WRX11X]

I just looked at my notes again and I had that wrong in my head sorry, it looks like 2011 was the pinout changeover.  The change in 2012 that I was confusing myself with is related to the AC and CE light wiring.    

So yes, your pic confirms you have the USDM ECU pinout.  

If you are not in a desperate panic, we may have a product coming in the next couple of months that would probably be the best option for you, I will PM you some info since I dont want to give too much away before it is in stock and announced.

Otherwise, yes, a wire-in ecu with an adapter loom is probably the next best option, this is quite an IO hungry car though so depending if you have TGV etc you might have to lose some factory functionality with this option.  The final option is to either re-pin the factory loom to work with the international plug-in ecu which I have never tried but I imagine would be a difficult job, or have someone make an adapter loom to adapt to the international plug-in.     

...I may be tempted and interested in this if it's still in the works. I've researched which pins I would need to swap to make the g4x work. 18 out of roughly 124 pinouts are the same. Also, some would have to be unpinned and re-crimped for the bigger or smaller terminal.
It looked liked the grounds are also changed a little bit.
Running a g4x in my miata made me highly consider getting one for my WRX and ditching the Cobb. But since I own a 11 it would be quite a bit of work to make a PNP... actually be pnp lol.

Okay, after some digging it's because of the R8 coil conversion.
GoFlowForce removes the wires that send the signal to the tach. The reason it worked with the speeduino, is that speeduino has 2I as a tach output. Link has 2I as an input.

The tacho jumper is needed on the 1.8's with 4 pin coils, I dont know for the '96/97 that had the 3 pin coils (looks like same coil but 1 pin missing).  I havent heard of anyone needing to do anything with pin 50 or 37 though. 

What coils does your car have?  

I think the jumper is needed regardless for all 1.8? So I put it in.
It's a 94, so its originally got a 4 pin, but I put 3 pin on for an r8 coil pack conversion. It was installed before the linkecu, while running a speedyefi.

Just put my g4x in and everything is working great and fired right up.  Except for tach. I noticed there was no jumper so I grabbed one I had laying around and installed it. From another post on here, I read someone had to swap in pin 50 into 37 and set up the tach thru PCLink and Aux3? I checked my harness and it has nothing pinned in 37.

[MX5NAX and R8 coils]

Before I make a purchase, can anyone tell me if the MX5NAX PNP can run R8 coils?
