Apparently, they have a prototype just about worked up, according to the ms3efi site and a grassroots article. Seems like its going to have a whole lot more inputs and outputs, USB support, SDCARD data logging and even more. That upgrade card is HUGE.
It was noted that the first version of 1.0 will be ready by summer, possibly in a price range of double of what the MSII board costs. I've been procrastinating on installing an MSII to use stock sensors, but im a little glad now that this new news has developed.
Damn, and I just got a MS-1 (for the second time). I was talking about resolution with a shop guy one day and he said that it really helps when you have some of the bigger cams - at least on the LSx platforms. From my limited experience with the gto, the stock cam is pretty good in a turbo car unless you're trying to squeeze out the last few % (or just want lope).
Does Hydra allow you to edit the bins though? I was under the impression they were static?
IMO above 16 x 16 unless you have a full on race engine more cells don't actually help any, especially if there's intorpolation in between them.
MSIII looks hot, It might be out in the summer but It's gonna be at least another 12 months IMO before it's close to viable for our use. it's taken 3+ years for a full release of extra code to come out for MSII!
So has the MS2 for the past couple of years. It was 12x12 before that, which is what the MS1 runs currently on the Extra code. Heck, the good ole' Link only had six MAP rows.
I think we're hitting diminishing returns, here. Beyond a certain point, more cells is just more tuning. It's not like the engine's VE is changing radically within the space of 250 RPM. Folks need to remember that MAP is still the primary input into the equation. Even if the VE table were 4x4, it'd still run reasonably well.

Could be, we'll have to see how things go. I'm pretty excited to see that MS3 is up and running at all, given that they're still debating how the memory is going to be mapped on the FreeEMS.
Assuming it does everything they claim (VVT, knock windowing, blah blah blah), and gets here within a reasonable space of time, this is going to be THE engine management system to have.
Its no a matter of how big you need the table to be its just that every other engine managment system Ive looked into offers much larger tables. My car runs fine with the HR code, but it would be cool to have a larger table.
I don't know why everyone thinks they need more resolution...most people don't even use what they have effectively. Too many people have VE table with these big blocks of linear change. Make that all one step (row) since it interpolates the **** anyway. Then use that saved resolution elsewhere, like where you have non-linear VE changes (eg. boost onset, where the motor "comes on cam").
