So I'm in the process of an e30 turbo build, I'm running a vanos M50 in the car now. I'm going to be using Megasquirt, I've been doing a lot of research on it thus far but I'd love some opinions from people who have actual experience using Megasquirt on an M50/S50 engine. I have a few basic questions between the differences of different MS options before I purchase.
If I bought MS3x I'd get the assembled kit, cause lets face it, I'm lazy... but I'd still wire a harness out of an old ECU so it would plug and play. So lets break this down by cost vs. time.
MS3x: Prebuilt $650 + wiring and harnesses $110 + IAT sensor $24 + Spark Boxes (in order to run M50 coils) $180
Total: Roughly $964ish

MSpro plug and play: $1500 total.

Questions:
With MSpro do I still need to buy spark boxes or coil drivers in order to run stock M50 coils? (I know thats a thing for MS3x)
With MSpro will I still need to put an 10k resistor on my crank sensor? (again I know its a thing on ms3x, but I'd assume since its plug and play they would have worked that out or they'd mention in on the page)
With MS3x is it easy to tune for water/meth injection? (they advertise this on the MSPRO page but I never seen it talked about with ms3x... This is something I'm planning for the future of the build so if this feature is much more simple with MSpro than thats a huge plus to me)
With MS3x would my stock MAF work just fine? I plan on running a blowthrough style system (MSpro has a built in MAP sensor that just needs a vacuum line to it, so that kind of eliminates the need for a MAF entirely... anyone running their M50 without a MAF on this system?)
Are they any other Major advantages to one over the other that I'm missing?
Do you think the Price difference is worth the lack of hassle and clean wire-free install of MSpro?
