Default Which ECM, and why?

Okay, if you could run ANY ECM on your ride, which would you choose? Looking for possible replacement of my MAST electronics. Money is no issue, and of course Id need a custom harness as well.
Assuming I ditch my MAST electronics, which at this point is a possibility, due to a wideband issue, Id love to know which way to go. The MAST stuff runs my gauge controls, has a simple to use software program, and is very high quality, so if I swap, Id like something similar. GM has made a gazillion ecms, so tell me whats the best in that line, if you suggest GM. Does GM offer a wideband setup?
Let me know whats out there guys...

the m90 was/is pretty advanced. perhaps the holley dominator or the fast xfi 2.0 are on that level. MS3 Pro for a more savvy diy type or go upmarket like MoTeC maybe?
are your gauges canbus or are you using the built in drivers on the mast ecm?

434” RED sleeved block with Mamo 265 LS7 heads. Mamo ported MSD intake, solid roller 254/268. T56 manual, with stage 2 kit. Made 616 last week, with faulty wideband circuit (not the sensor)

Analog gauges, driven from the M90 ECM.
I love the MAST setup, but if we cant get this wideband figured out soon, Im done. Been screwing around with issues since January, and Im ready to put my ECM issues to bed.

If your swapping, I would probably go with a Holley Dominator setup. It simply has the most options for the $, and is fairly user friendly. With built in controls for N20, boost, traction control etc, it's hard to beat it.

I prefer megasquirt because it's flexibility, options and community support. Open source software and hardware. And of course price.
Haltec is another good option, but up there on the price range.
I stay away from microtec.

Work with your tuner, if thats you? Stock GM or Holley will have the best tuning support. Holley maybe moreso these days
