DS, sorry your thread got highjacked.  This is the last post on this, when I have more questions I will start a new thread.  Thanks for inputs everyone, I am also looking at MoTec because the shop in Tulsa uses them and you can get a tune for a subi 2.5 turbo which will at least get it running.

Don't mind at all. Mo tec is a solid system.

Throwing out my 2 cents. I use CB Performances ecu on my trike motor. it is completely unlocked and tunable.  the same ecu can be used on a subaru Motor. Mark at CB Performance has allways been helpful with set up. mark can VPN to your ecu and assist with the tune. for a fee of course. i have been very happy with the tune on my VW motor. i can't say what his Subaru tuning skill set is,  but it might be worth the call. https://www.cbperformance.com/Injection-Kits-s/288.htm

Good info !

Didn't you have your suby tuned by chris?

What ecu was that?

not the 2.5 suby. i had him attempted to do the 2.0 suby. i basically ran into the same thing as fabr. when i got home and put it in the sand,it would put me in a limp mode. i finally dumped the old program back in it. that motor is still running in my buddy's street car just fine.

This pic is from Ron Williams, he rebuilds transaxles. This one 8s an s4.  He said the owner g'd out to hard at the bottom of the dune and broke the case.  So I consider that bottoming out really bad and I have to wonder how hard they felt it.

I am losing my enthusiasm for this whole deal.  May need a new ECU, they don't make the stinger any longer anyway.  I have a name of another dyno shop here local and may try them.

What engine do you run again?? Factory butchered harness??
There are a couple plug-and-play options out there for a Subaru using a factory style harness. Otherwise update to a modern stand alone ECU with all the options. Holly, Link, MS3 all do the same thing, it is how many inputs and outputs the board supports. I have run them all but keep going back to the MS platform because of the tuning software that runs it. (I cant stand the clunky feel of the holly terminator software)

This is the new MS3, excellent bang for the buck. Wire it in, set up your project, hit the MS forum and grab a base timing map and start tuning.
