The DIY aspect of MS seems to bring it a lot of critism, as if it should be dismissed as a backyard EMS. This isn't the case, there's thousands of electronic kits out there doing all sorts of things, that are as good as commercial products. As long as the electronic components are of sufficiently high quality, assembly & soldering skills up to standard, there's no difference.
Hell, if you had a circuit diagram, you could duplicate an AEM or Motec or any other EMS for that matter.

What I'm interested in is how the MS&S is configured. As in does it function with stock MR2 sensors, or do they need to be re-configured or replaced. Is it compatible with the OEM wiring and adapt to OEM connector. What type of knock control options etc. Are there any deficienties in the programming.

All EMS's do the same thing basically, it's just a matter of what whistles and bells they have, what options, and aditional outputs etc. They all have to be programmed and tuned to the specific vehicle.
I'm interested also, but I don't want to mess around forever pioneering the best setup for the 3SGTE, I want to get what's necessary, and fit it. Do it once, and get it right.

^^ BTW doesn't the 'error' board deal with the 3SGTE dual trigger distributor.
and really, I wouldn't install the MS without setting up a crank trigger anyhow.

Oh, and I doubt if anyone could get this setup right for a couple of hundred bucks. By the time you look at multiple outputs, sensors, O2 WB, data-loging, triggering, ignition etc...gonna be like 5 times that. But maybe it's worth it, it's still half the cost of an AEM with all the options as well.
Just my thoughts..
