megasquirt

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.

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.Im sure ron will do it with a little convincing. I have something to show you and I promise you will never go to MAP.
I really think on your first build you will have enough to deal with to not have to worry about a barometer setup. Unless you need a new map, i would start with the stock map sensor, and then upgrade when you need to. Saves some money and the start in case you have problems, and possibly saves some headaches if you have any problems with it.

i haven't looked @ms software in years, but 4 bar resolution sucks, plain and simple. street cars with 4 and 5 bars do not have proper idle properties and drivabilty ESPECIALLY if you have camshafts or low vacuum @ idle scenarios. Baro correction is generally not needed on street cars, but it is ALWAYS in OEM calibrations and there is reasons for that. Most of the stand alone systems are pretty gross in how they work compared to an OEM quality PMC/ software. Yes, anything you can get will work, but there is many disadvantages to stand-alones in alot of cases.

Arent there ones that have been put together to they a plug and play for certain cars...Yes they are. Lets leave this thread to the guys that actually KNOW ABOUT THE STUFF. If you dont know, or have a legitimate question pertaining to the thread topic, then stay off the thread.

also thanks for the input. and thats alright im having someone make me mine that will practicly be plug and play. and yes on their website their baro correction did appear to be kind of ghetto lol

well, weather you use the plug-n-play or use the non plug-n-play, if you've never used megasquirt or ms/ms extra software, try and find someone familiar with it to give you a helping hand with it, once you've used and gotten familiar with it you will love it, nothing like being able to tune your car from your laptop. as for my last post on the distributorless ign, i must have missed the fact you were planning on using the plug-n-play for a certain app, wasn't trying to be a smart ass, i was assuming you were going to build/have built a generic megasquirt, so i appoligize there.
