Standalone ECU? NB MSM
My 2004 MSM already has a Begi tune-chip in it with bigger injectors, but my AFR is still a bit leaner than I would like.....so I am looking at stand alone ECU so I can tailor the AFR a bit more rich (thinking 11.5 for track duty)....
ME442 looks good and lots of people use Megasquirt...... Since I have an innovate SCG-1 wideband/boost controller I could use the ME221...BUT it can't hurt to have 2 widebands to compare data too for not much more money in my opinion.....
What does everyone think?

Who is going to do your tuning?
Within some boundaries, I'm a fan of finding a local tuner with a stellar reputation and asking them for their recommendations. Do a sanity check on their recommendations. Then choose. If their recommendation is something from left field or if they refuse to tune anything except brand X, walk away. If they give you their preferred brand and one or two alternates, they're probably sane (if they're common brands).
A good tuner can tune any modern ECU, but they may work most effectively with a particular brand. If you're going to spend money on dyno time, you want to maximize the time they spend tuning, which means they should be very comfortable with your ECU software. Saving a couple hundred bucks on your ECU may be more expensive in the long run if your tuner is spending time learning/fighting the software on the dyno.
There are a lot of good options out there. There's a history of MegaSquirt love within this forum for reasons that could fill a dozen threads, but it is no longer the answer to every question.

I haven’t found a local tuner….everything is remote….. the upside the college where I work has a dyno….so dyno time is free, but I would have to tune…..I’m somewhat comfortable tuning the basics like fuel-spark-boost….but not as good at knock etc….. my last racer had a stand-alone that was very basic, but didn’t have knock control….which ultimately killed the engine :>(
I know the stock ecu has knock, which is great….I can always turn boost down if I encounter problems
