Yes, get a wideband guage, it will make it much easier to tune.

Do you plan on building the MS ECU yourself? Or does the Miata 1.8 lt plug and play work? MAP or Ron will be tuning my car. I would like to have Ron do it, but I just don't know if he'll touch MS or not.no there is a guy on club protoge that builds megasquirt for escorts, protoges,323's and tracers. the miata one doesnt work due to their distributorless ignition. yea from what ive heard a lot of tuners wont even touch MS. i might try to tune myself. many people have bought from him and i guess he is really good with helping out on tuning.

i have an aem ems in my car and everyone i talk to with my platform doesnt use baro corrections. if you are using speed density why do you need baro corrections.. matt, dave, nate, and anyone else i dont konw about, maybe you can help with this question too?

cant use with distributorless ignition???? hmm you can use it with just about anything, with the right parts. building it yourself is part of the fun.

baro correction is only relevant if you'll be changing altitutdes (or if you drive into a hurricane or something) during the same "boot" of the MS ECU. Otherwise, it reads the base pressure upon bootup and that's what it goes with.
Last time I had looked, multi-sensor baro correction in MS was quite primitive.
I think I'd skip fooling with it for your first build, to be honest. I'd also stick with the normal map sensor.
A distributorless ignition isn't necessarily a problem with MS. On some builds you'd want to read the crank position via the hall sensor on the distributor, but a 60-2 wheel is a better place to read from anyway. For actually getting the spark to the right hole at the right time you've got a few options, espeically if you load the MS2-Extra software into the system.
I've got a built MS2 setup that I never got around to installing that is forsale, btw.
