@Chris60M8 MS3 tunes are unheard of for this engine, unfortunately. Mike & Alan have leads on a supplier for ECU's that will come pre-loaded with base tunes for stock & boosted however(soon to be developed), so I'm not too worried. The series of MS boards were my first choice too, but now I'm conflicted. Performance Electronics have some quality options, but MS has an extraordinary amount of expansion capability. Really just looking for some guidance from the men in charge at this point. @hinton & @vt951 , I know which ones y'all will be going for, but what are your thoughts on the MS system vs. everything else?

Personally I don’t have a complete cooling system plan yet. I think I’ll use the factory thermostat and it’s housing on the left/driver side of the engine. The coolant port on the back of the engine does need a fitting that clears the firewall. If JWebber comes up with a good solution, I plan to use that. Otherwise, I’m guessing it will be fairly simple to fabricate a piece.

traction control? Yup
boost by speed? Yup
electronic boost control? Yup
two step? Yup
flex fuel capable? Yup
meth injection controlling? Yup
VVT capability with development support? Yup
cost effective digital race dash? Yup
its very promising!

I have an MS3 for my widebody car and I am selling it to go PE instead. After discussing everything with PE, I believe they have the same functionality with a superior UI and factory support. Alan and I both left feeling very impressed and believing that the support we will receive for development will be unmatched. I’m going to do a video soon of a shop tour and technology overview, and that may help you decide.

I've been planning on going MS for a while to control the 2.5, but nothing is in stone, yet, so depending on pricing and packaging, my options are open.

We will be taking our cars, Turbo and NA to their shop for them to do base maps that we can then share with the rest of the community.
They will also be developing a swap harness for us. The plan is to have integration with their digital race dash or the factory instrument cluster.

Performance Electronics. That’s the manufacturer of the ECU that we are partnering with.

I do 12v electrical as my daily living, so the megasquirt has never intimidated me, and I've never really looked for a "Plug & Play" solution, to be honest. I had planned on tuning the 944 2.5 myself, and would not entirely fight the idea with an 07K, either.
I am intrigued to hear about where that goes, but does anyone know if these engines are controllable by Megasquirt? I don't see why they wouldn't/couldn't be.
Either way, I'm all for whatever will make this work in the end. I love the entire concept.

With that being said, if you need an MS3, mine is sitting on the shelf waiting for someone to come along with a wad of cash 😂

Hmmm. Upon reading into the PE, further, I do see where you guys are coming from. What an awesome system. I like the idea, definitely. I'm assuming a knock sensor can be hooked up to it somehow through one of those many inputs?
Also, does the 2.5 have a knock sensor? I'd assume so.

It really is a perfect fit! I ran across them at the PRI show not even knowing they were 5 minutes away from my house. Small world!

It does have knock sensors and the PE ECU has comparability with them. We will be able to ignition tune for peak torque while monitoring knock sensors, pull a couple degrees after finding the limit, and then the ECU will be able to pull timing if there are issues with fuel/heat etc in the real world.

Since you are proficient in wiring it would likely be more cost effective to do it yourself. However, tracking down all the correct connectors etc can be a pain. I’m guessing the harness will be around $500, although it depends on what loom / heat shrink we use etc. some of that stuff is $2.50 a foot, crazy. Will also vary drastically based on how many we can have made at one time.

The engine guru/master fabricator I know has an 07K sitting in his garage right now as far as I'm aware, and may be willing to help come up with something for us.

I saw what they were talking about earlier when I pulled my 07K for the swap. The coolant port on the back has 3 outputs, and they're all angled outwards. It's designed for the lateral setup for front wheel drive cars, so the ports are made to be accessable. If you were to drop the engine in as it is, the plastic port would hit the firewall, so ideally what we need is a low profile replacement with like a 90° elbow for a hose to hook onto in order to run it back to the radiator. Of course, there's the exhaust to worry about too, because running it on the other side would mean weaving it around the intake, and that side of the bay is already pretty much taken. So there might need to be a metal pipe in place of rubber hose so that nothing melts, but that all depends on your radiator you choose.
