Someone makes a plug and play MS for the M50NV (and others). Not too sure who. Anybody know?

so I'm at $315 for the ms and daughter board.
then i need a wideband and some dyno time. right?

why would you use EDIS these days.. with a 60-2 crank wheel and built in coil ingitors there's just no need.
did M88s use 55pin motronic setups? If I were any of you guys I'd seriously be looking at the DIYpnp from www.diyautotune.com.

btw, I think I'm going to use the cheap GM coil packs for V6 motors, the "two tower" style ones. They're DIRT cheap and work great for wasted spark and they have well documented specs for megasquirt. I'm still trying to decide how I'm going to get crank position information - I have an eta which doesn't have the 60-2 trigger wheel. I can buy the trigger wheel which will bolt on and the sensor, use a board to translate my current reference sensor & TDC sensor to generate the input megasquirt wants, or use another solution. Etas are a PITA to get working without a prior 327i build! I will be swapping the 885 on to the car, but I'm planning to keep my existing harness because I won't be using the 173 DME.1997 540i/6 - stock

link?
also, whyt wouldn't he just swap out to a M20B25 crank pulley and use that for crank reference?

he could but it still needs wires, and you still need things like a real TPS, a coolant sensor, IAT, etc. etc. It's just easier with the later harness. also etas fire all 6 injectors at once, B25s alternate in banks of 3 which isn't fantastic but it's certainly an improvement. Along with all the other improvements starting with an eta harness would be a waste of time.

sorry for all the questions, but i have more.
How reliable are these setups? I can solder just fine and reading a schematic and wiring isn't a challenge either. My only concern is that i spend the money to build this and then it is a nightmare to keep running.
Also if i have a few spare 55 pin DME's whay couldn't i just use that for a "direct plug in" setup? is that possible?

yes but you'll have to figure out what pins should go where between MS and Motronic, and of course build it, and add modifications, etc. etc. There's a few writeups on your own PnP setup. I've created a chart that shows how I built mine:
otherwise they're pretty reliable - it's been about 3 years with mine. Hell, maybe even more reliable, since when something goes wrong, you plug in a laptop, see exactly what's happening and fix it.. with the stock computer you're shooting in the dark most of the time, or relying on the somewhat useless check codes.
of course this is assuming you don't fuck something up to begin with (wiring, soldering, etc).. which is why I like telling people about the DIYpnp option. So many people get screwed up on the hardware side that they never get their car running well enough (or at all) to take advantage of the power and options before them..

And yes, I know I need all those sensors. I'm really considering a custom harness using the diyauto harness... then the labels would be printed on the wires.1997 540i/6 - stock

M88 uses the 35 pin motronic, same as eta. I've heard of people using an M20 harness with it when they go standalone, so PnP may still be a viable option... Need more specific information sources...

it's pointless. you can do wasted spark without it, all you need are a couple $5 coil drivers (Bosch BIP373s) and somewhere to mount them.
it was the "hot" setup like 5 years ago, before MS really had developed built in spark control. think V2.2 boards, which were only meant to control fuel. Now you can buy a DIYpnp with everything built in.
you could also use an M30 harness, the M20 harness will fit but it's tight. M30s used the exact same 55 pin 1.3 ecus.
