I looking to wire a Ms3x3.57-c With 1.3.4 Can Enabled firmware with the DIYbob PNP. Also Have the have a innovate lc-2 and the Gm- AIT.
Car 1990 Miata 100% stock low mile (80,000miles) Runs great has no starting no running problems, Looking to get the car running on the MS3 1st and maybe boosted it this winter. I have searched lots on how to wire it found some pinout pics and such just not sure on if i need to add jumper in the box to even run the expansion board yet or just wait till the car is Boosted to run the spark, fuel and boost of it.
Do you mean it doesn't have starting or running problems, since you said it runs great? If it does have issues, I would solve them before going Megasquirt, or at least narrow them down to an ECU issue. If it runs poorly, you'll be chasing issues when you're trying to start on a new ECU.
http://westfieldmx5.devocht.com/ Find the 90-97 MS3 build manual in here. Follow the guide on how to build the board. Just ignore the parts about mounting the stock ECU connector in the case. Then use the pinouts to make your DIYBOB.
Don't wait until the car is boosted to sort this out. Get it running well on MS3+MS3x first.

OK one question with step 2 fuel pump for 90-93 looks like there is a link missing. Also my ms3x was pre build do I need to open the box and add jumper or anything.
ignore the westfield since yours is prebuilt. I am not sure if you need to add jumpers on the prebuilt units or not, i would let someone like Brain respond on that. As for the chassis wiring, see the pic below. That is how i have my ms3x wired up to my stock 93. Yours should be the same.
I have a wire going from sj10 - Q16 center hole. This wire Needed or it should be remove?
The s12c to js9 is alread done. A long with the the 2 white wire and 4 Orange in the link you sent
js10 to q16 is setup for a simple dizzy wheel output. no harm in being there.
Ok sounds good. Would you have to have a start up file?
Also can the be started with the maf still in or am im better to just instal the AIT. I have the part on hand just want to get it started on ms3 before i make a cold air intake
just hook it up the IAT and stick it in the intake. easy and quick. You can use a startup map for the ms3 pro. That is what i am running. I can send you my map since your car is bone stock still but i cant do that till i get home.
