Megasquirt ECU

Has anyone had experience with a Megasquirt ECU and the associated
tuning software, etc? I am considering installing one of these in my
1996 Miata and would like some first-hand tales about the
effectiveness and any power gains experienced. If the unit simply
emulates a stock ECU then I don't see the advantage.

Thanks

IIRC, FM says a Link ECU can add 20 hp to an NA, if it's fine tuned on a
dyno. I doubt the Megasquirt is much different, except for the much
lower initial cost and the much steeper learning curve. Note that you
lose emissions control, if that's a factor in your location. I don't
know how OBD-II is affected, but at a guess it will be disabled.

These replacement computers are intended for cars with more than 6 psi
of boost, for which the inflexible OEM ECU cannot provide proper fuel
and timing control. 20 hp is barely enough to feel a difference; a
low-end supercharger should add over twice as much power, and be
considerably easier to install.

It would be an interesting project for someone who's more concerned with
gaining an education than ultimate results.
