We're getting right to work on the 94-95, the real work will begin as soon as I actually buy the car, as I decided the first time around it's probably better just to buy one, do the work, keep it around for a while, drive the crap out of it, and oh yeah, maybe sell it one day
I'm shopping now. I can't give you a solid date as once I do you'll hold me to it
-- But I'm going to make it happen as quickly as possible, and on paper it looks like it will come together pretty quickly based on all the work we've do so far. The case doesn't have to change which is a big deal, we have tons of connectors in stock so there will be no leadtime issues there. Those were the big issues the first time around. This time will be a cakewalk compared to round 1.
I'll update you guys as it progresses...
As for 3.57, it is like 90% surface mount, meaning there is better quality control on the assembly and better vibration resistance as well. It also has a much improved idle control circuit that is loads better than the TIP12x solution in my experience. It gives you a broader range of idle speed control, much more like what the stock ECU offered on a Miata.
Other than that the whole board was looked over, a few bits were updated here and there where it made sense. Outputs were made easier to get to on the board, etc. Most of that doesn't directly effect the MSPNP user though...
