He's done some good work for my son's turbo-Subaru bug. I don't know cost or anything, just noticed those while looking for some other things.

Microsquirt doesn't have a built in MAP sensor. But I'd wager on an external MAP sensor. It's the easiest to set up. I wouldn't be surprised if there is a TPS involved, but usually it's pretty much ignored unless you have a wild cam at idle.

That is also correct, the Microsquirt does not carry an internal MAP like it's big brother. Another reason the MS2 V3 is my goto.

I disagree on the external MAP being easier to set up. It adds wiring, and if you want barometric correction for spirited mountain driving you need 2. Adding more wiring. On the V3 board you just add the MapDaddy sensor and call it a day. Using the same singe vacuum line that is going to the ECU.

TPS isn't necessary with Speed Density fueling using a map sensor, but it sure helps with acceleration enrichment. I've always had a hard time getting reliable acceleration enrichment's just using engine vacuum variation. Not that is can't be done...

TPS data in a log is invaluable IMHO, it really tells you what the driver is trying to accomplish during the drive.
