MS3Pro Module PNP - can you make this for a 99? I'll be buying a mspnp this winter.

Your OP leaves out 99-00 from the new offerings.

For those in the cheap seats, would you care to elaborate at all on what the added benefits are vs the MS3X?
I see internal datalogging, sequential spark, traction control (for ABS cars?), better MAP sensor, stock knock module (?), water injection and/or 5th injector setup (8 inj banks), better table switching, launch control... and?

whoops. should be 99-05. thanks.

Benefits:
  • An OTS, stamped, ECU--not hand-populated and soldered--with integrated RTC and Knock modules. It is essentially the same board used in the MS3 Pro.
  • An OTS, printed adapter-board which allows the omission of a hand-built/soldered patch harness that could lead to errors/failure.
  • The adapter board is populated with the required circuits to run a miata, as well as additional popular circuits for customization:
    • constant barometric corrections
    • additional analog and digital inputs
    • bluetooth module
    • wifi module
    • alternator circuit -- if you dont wanna use the software to control it
    • alternator charge light circuit -- if youre out of outputs to waste on this
    • Speeduino VR conditioner
    • (4) additional VR conditioners -- these can be used to add traction control
    • EGT circuit
    • TinyIOX circuit -- for additional sensor inputs via CAN
    • Active low circuits
    • Accelometer circuit
  • Installs within the OE ECU case (requires some cutting/drilling the case) for easier installs -- no zip ties needed for NBs.
  • Should take considerably less time to assemble/deliver.
One downside with Frank's design is the lack of an input/output connector. The reason the 96-97 costs a little more is because I can utilize the extra 12-pin connector on the ECU harness and bring any inputs/outputs into the ECU through a provided pigtail -- Don't really have this option with the other model years.

So until I come up with a better solution, there will be be some wires coming directly off the board (like for wbo2 12v, ground, signal) for all other units -- which i still have to do on my current 96-05 ms3x builds.

Oh that sounds awesome.

Re: Zip ties for the ECU. I drilled holes in the singular bracket and have my MS3X mounted in the stock-ish location. I did use zipties to put the ecu on the bracket because I didn't have the right sized bolts lol.

As an aside, the base MAP sensor on the MS3X is 2.5 bar vs 4 bar for the MS3 Pro, correct? That's also a factor for anyone considering things. 2.5 bar is dandy for a stock motor, the second you build it you're going to want something that goes higher.

For these, it's still a 2.5bar as default -- that's ~22psi.

I can offer them with a 4bar, but it will change the cost a little; not much. Or you could use the GM 3bar and install it remotely inside the engine bay.


The MS3 module has no map sensor on it.

I guess offering the 4 bar would be helpful unless you think the resolution is crap. 22 PSI limit means that's where overboost should be set, so realistically you're looking at a MAP of 235-240 tops so you have a bit of wiggle room for overboost protection. That leaves you at about 20psi. Still plenty, but you always end up wanting more lol.

I need to clear my stock of NB boards, so I'm dropping the price of the NB units for a limited time [till the 26th].

99-05 w/o baro - $950 shipped
99-05 with baro - $965 shipped
