What an amazing place this is!!!
On to ECU's
I'd been thinking about Megsquirt for my build but their DBW stuff seems to be a bit behind in development compared to the commercial vendors. There's so many to choose from.
MaxxECU, thanks Rivet, at least it has Bluetooth. To get Wifi with Haltech, it's going to be about $2,500. I don't think it's even an option with Link. Since Link only sells through dealers, it's hard to get a handle on there pricing. I checked with four vendors near me, based on Link's website, none of them even list Link as a brand they sell. That's troubling all by itself. I did find a dealer in Florida with pricing.
It looks like MaxxECU sport is a good fit but it doesn't have knock sensing. For that, I'd need to move to a more expensive ECU or use an external module. Adding anything external adds cost so it doesn't make much sense.
All Link ECU's have knock sensing.
So it looks right now I'm looking at:
MaxxECU Race Premium for about $1900
or
Link for at least that much, probably more
Any other vendors I should be looking at?
I don't know of any tuners near me that will help. If I find one, that may change my choices too.
EDIT - I forgot to add that the Haltech Nexus R3, although a lot more money, has power distribution built in. I'm not sure I care about that but if you do, $2500 will likely be substantially less than a MaxxECU Race ECU plus a MaxxECU PDM.

My pleasure, montauk.
I think if you decide on purchasing a Maxxecu EMS the Race model is a good choice if the budget allows as you will gain not only two knock sensor inputs but you will also gain H bridge control for drive by wire and additional inputs and outputs for future expansion.
Knock sensing is a valuable feature for sure but it does take considerable time to tune as an FYI. Our motors have quite a bit of mechanical noise to begin with and will take some trial and error to set the knock detection filtering to properly work along with adapting knock sensors in a correct spot (i.e not on the cam case nor on the heads). I do this on the dyno in conjunction with stand alone knock detection tools to dial it in and can be time intensive.
The newest Haltech products and their new NSP software/firmware has been a bit buggy lately as they polish the feature set and have a few idiosyncrasies when updating that need to be adhered to but it is a good option. The hardware is quite nice I have to say. I am a dealer for them as well.
The two other brands not mentioned that do an excellent job both in hardware and software is Emtron, and Motec obviously. While I am not a dealer for either of them I do have experience with tuning both of these in a race setting and think they are great options while not my personal preferred choice.
