A. The umbrella name is Megasquirt. Microsquirt is a subset. Microsquirt has 2 types; dedicated sealed module & microsquirt module which is what's in the MSPNPG2. Both are MS2....
A. I am considering getting Microsquirt next year to start to learn to tune with my near stock setup. I'd want to gain a decent level of familiarity tuning with TS before either adding a turbo or a H/C/I to my car a year later.
B. I'm in research mode and have a couple of questions:
1. What do you MS guys do with your EVAP/charcoal canister system? I wouldn't mind deleting it all as I don't need any emissions crap on the car. However, I don't want my garage to smell like gas all the time so just venting it to atmosphere doesn't sound appealing.
2. I'm leaning toward Microsquirt while turboing the stock long block. I have a 255 lph fuel pump and stock injectors (34lb) off a friend's 2011 Coyote mustang that I would like to use. I am running a junkyard 70mm MAF off a 94 GT so the cost savings of going MS and not needing to buy a new blow through MAF would be nice. I also think learning to use TunerStudio looks much less confusing/intimidating than using Binary Editor with QH. I already have a WB and feel that I am patient and studious enough about learning to tune. How does this plan sound?
There is Megasquirt 2 (MS2) & Megasquirt 3 (MS3). MS2 firmware is fully developed; MS3 is more advanced & still being updated.
B. Research Mode is good. Keep it going, it will never end. After 5 years, I'm still learning new things.
1. Leave it alone, do nothing. All my emissions stuff is intact, it's no longer in control by the ECU.
2. MAF is not a requirement for Megasquirt. They are all Speed Density & come with an onboard MAP sensor. I am one of the few that use a MAF & MAP in combination but the converts are growing because it seems to work better for boosted applications. You can use any MAF in a blow-thru; the mass of the air does not change from inlet to throttle body. You will need the calibration curves for both the injectors & the MAF. You can download Tuner Studio Lite which is free, to become familiar with it. There are 2 paid versions, MS & HD. It is called the User Interface (UI). There is no comparison between it & BE/QH. The UI is what sold me on Megasquirt.
