We don't have any particular issue with the CAS. It works fine as far as I know.
As far as the OMP goes, how many other ECUs have their developer posting on this forum? I am going to write OMP support for the MS3. In most cases when people with S5's find out we don't support the stock OMP (or just because the OMP isn't a very good way to lubricate the seals anyway), they go to premix.
The thread you reference is a VERY poor example. That user showed up at my house with an MS1 (we have moved WAY past that in terms of capabilities, and we aren't even usig anything like the code that was used there) that he had spliced into his stock harness using radioshack wire splicers that weren't even the right size for the wire. If you moved his harness a little it went from starting up to not starting. If that install is what you are basing everything on then you should get the facts straight. ANY ECU would have problems wired that way.
The MS3 is a completely different and essentially unrelated ECU. So much different in fact that I would still say that nobody has tried to install MS on an FD. It is not because we can't run the FD engine that nobody has used it, I will guaruntee we can run that engine just as well as any other ECU; it is because nobody is willing to be first.

That user also didn't work on his install for the entire 1.5 years. He was in the military and got deployed shortly after starting his install IIRC (In any case he stopped working on it and was not in town).

Head over to the Megasquirt forum in the Engine Management section and do a bit of reading. Installing a Megasquirt is like installing any other standalone, really.
MS3 supports E85 using a flex fuel sensor: http://www.msextra.com/doc/ms3/flexfuel.html
The MS has supported the FD crank sensor and ignition since MS1, but MS3 being the newest version with sequential injection and a host of new features, it is the 'Squirt you want to use. You'll need the V3.57 main board, MS3X expander, MS3 daughtercard, and then the typical MS wiring harness as well as the MS3X harness. You can buy all this pre-assembled from DIY AutoTune, no electronics knowledge necessary.
You can control the twin turbos with some work since there are plenty of spare outputs, but as far as I know at the moment there is no plug and play setup for that. You'll have to set it up yourself and experiment a bit.
It sounds like you have a lot of experience with MegaSquirt to be making such a bold statement. I'm eager to hear of exactly what your basis is for this opinion.

[QUOTE=Sgtblue;10928216]Oh really. Take your rotary powered car to any experienced piston mechanic and have him rebuild it, modify it and then tune it. Let us know how that goes.
The rotary engine is the most simple engine to rebuilt and any experienced piston engine mechanic will be able to build one if shown how to. And on tunning its all the same just some engines will req more fuel than others.
And for the megasquirt the reason some shops would not recommend them is because they are stuck to what they have been using for years..search for a 2.3 ford mustang own by huber on youtube and you might change your mind about megasquirt.

I ‘m considering the Megasquirt3, currently I’m putting together a single turbo high HP, track/street FD, (hoping to get the motor and trans in by the end of the month) E85 for fuel, I’ll get all the great benefits of E85 and will simplify things a bit which is a plus.
I currently have a PFC along with a Datalogit. I read on the forum how it’s difficult to control larger injectors on the primary side especially with E85, also it’s a ECM with no further advancements other than its current state. I have an automotive background but I am new to the FD /Rotary, (my first import) the Rotary has been a learning process since day 1 (2 years or so ago). I’m looking into the MS3, I need to learn about its features, tuning flexibility, fuel flexibility and data logging capabilities (very important to me) and if it’s fully capable to manage the FD completely. If I have to learn a standalone why not use something that’s current, has the potential for further growth, also there’s a software engineer associated with the MS (muythaibxr)
, (I believe, correct me if I’m wrong ) that’s into Rotarys and on the forum (both a big plus). The MS3 is very affordable, especially if I build it myself. On the flip side, the PFC is very popular, with that comes a sense of ease because it’s a common platform in my area and has a lot of great support here on the forum. Don’t know, I’ll keep doing the R&D.

We shouldn't have any problems with E85... that's just tuning really.

Also, if there's anyone in the Maryland/DC/VA/PA area who has an FD and wants to run MS3, I'd be happy to help you get it up and running.

Hi Ken, your recommendation going the pre-built route makes sense to me especially because I bought the car disassembled, I don't want to add any more headaches trying to track down something I did in the ECM. As far as the OMP, I’m going to do the pre-mix so, all is good. Thanks

You should use the flex fuel sensor because you never know when you may need to fill up with regular gasoline, or a mixture that isn't E85 (half a tank of gasoline, half a tank of E85).
Don't just add 30% fuel, because stoich on E85 is 9.76:1. You may be tuning down into the 6s under high boost, and you can run much more timing advance. Plus the entire fuel system must be E85 compatible, which means no aluminum, among other things.

No, it's not quite that easy.

since lambda is set for gasoline it'll read just like gasoline. 14.7 actually is 9.1
