I want it i need it.....its time

It doesn't need to be permanent. Use a slip on extension,sealed up well for the tune session. Remove it after the tune session,run in open loop. The drawback to not running an O2 is no compensation for varying air conditions/altitude. It will only consider throttle position and  and airflow or mass. It will not be able to hit target AFR's via the O2.

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.

Where is that can of worms? Oh there it is ,we already opened it..................

So your ecu is like my megasand trans 

If I were considering a modern open source ecu and I had a tuner in mind I want ed to use locally, I would call and ask which ecu he know best.

I called Wichita dyno and they only work on domestic engines.  Maybe I didn't think this all the way thru.  I think I will just bolt a holley carb to it

Wonder when they changed policies? 

As far as the holly idea.

I haven't kept up with all that is available but I would consider Holley EFI. Not the base units though. I forget the name right now.I agree with DS about using a tuner that is very familiar with whatever you decide to use. That or learn to tune/log/tune/log/tune etc. yourself. I personally recommend that. If you understand tune basics ,and I think you do,it is not all that difficult. The bonus is that you KNOW your system when it tells you to pound sand.

I think both Glenn and Jerry were not really happy with their subi tunes. Maybe Chris found it best to concentrate on a well known segment of the aftermarket performance . I mean everyone has an LS and tunes are basically available everywhere. Not hard to just cut and paste an appropriate one in and presto! you're tuned.

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.

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?

This absolutely true!!

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.

[DeepBusch69]

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.

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.
