So I'm the proud new owner of a 3rd e36 (all bought in the past 60 days). Lol. This one is a 95 M3 so no emissions required. Still wanting to be on the OBD2 list
So I'm going to need someone to fill me in on this dead time stuff and it's going to be a deal breaker rolling between 93 and e85.
Also, launch and traction control would be icing on the cake

He just meant that you can blend between all the fueling and timing settings. For example you can have cranking pulse widths set for gas and for e85 and it will automatically figure out the right amount for E45 or whatever. You cant do this for the injector dead time, but you will not need to do that anyway because dead time will not change between ethanol and gas unless you are also changing fuel pressure. Trust me, this is a non issue, your reading to much into it.

Launch control is super easy, you just need to hook up a switch going to ground and turn it on in the software. I use the horn buttons for launch control in my car and I can build 20 pounds of boost in neutral at 4Krpm
I don't know alot about traction control but it is natively supported in MS so yes you can make it work. I think the stock wheel speed sensors are VR sensors so they will need a signal conditioner in order to wire them to the MS. They just need one drive, and one driven wheel sensor. If you have the two wheel speed sensors reading you will be also be able to do boost by gear.
traction control can be done a bunch of different ways. The way that works best for me is progressive spark cut using a front wheel speed vs a rear wheel speed (so stock rear diff sensor compared to stock ABS sensor) Like SG2800 stated, you will need to convert the VR signal to square wave, which can be done via a 50$ converter or make it your self for very little.

Theoretically, the dead time might change a tiny bit between gasoline and ethanol, but the change is tiny and almost nobody actually has the right info for performance injectors anyway. It's the kind of hairsplitting that is needed to hit factory emissions targets but not something your average enthusiast will need to get dialed in. So we made it so that it can blend everything you would reasonably be able to get the data for.

Thanks for all the info. I'll have to do some reading about everything.
Any recommendations on a compatible ignition coil upgrade?

the stock coils are pretty stout, but if your going to upgrade to a coil that doesnt have OEM fitment, then id suggest the LS truck coil. Cheap and awesome, and they dont require a coil driver (good for non-PNP installs.)

I'm interested in an OBD2 unit

Well, can someone confirm if this is a good idea for me?
Right now I've got a VF Engineering Kit with the VF Tune. My plans were to go E85 and more boost with an RKTunes tune but theres still no true flex fuel capabilities on OEM ECU.
With this MSPNP, can I adjust the base map for my supercharger setup and from there tune for flex fuel? I've got a lot to learn
Flex Fuel is one of only 2 or 3 reasons I chose a stand alone over the stock ECU tuned.
My main reasons were these:
1. True Flex fuel! Not map switching or anything like that but a true blended map that goes off ethanol content.
2. Integrated Boost control! The ECU can control it and cut boost if it's running lean.
3. A full Wideband sensor input instead of the stock lambda sensors. Gives true control over the fuel maps for safety and for better tuning.
PNP setup will be awesome but I'm also glad I built my ECU. It was a ton of fun to build and that moment when it finally fires up and you realize you built all of it is quite a proud moment.

Yeah this sounds like a better idea then. I'm in.
Please put me down for an OBD2 in the group buy. I assume by PNP you mean unplug stock ECU, plug in MS3 unit to connector you unplug from ECU, tune and drive?
Looks like OBD2 now has 10+
