"it will be released sometime in 2013"

Comes out Jan 2nd.

You guys don't mess around

Quick question: the wiring harness you talk about, is that a pnp one or generic that one would have to modify to fit their year?

I had two weeks to make a harness for mine; I'm so lazy.

I believe the harness that comes with it is a generic harness. You could always pick up the DIYBOB and build a PNP harness with it.

It's generic. there's 8' of wire on each of the two connectors you see on the MS3pro. One has integrated USB input, the other a serial.

You'll want to get a DIYBOB to complete the harness for most "PNP" installs. you can then put your MAP sensor inside the proto area of the BOB, which is what I plan on doing. Maybe I'll do it today and show you.

challenge accepted.


Matt, am I correct in thinking that the serial cable port and/or the USB port can pull off the internal datalogs on the SD card inside?

Yes it can, albeit it will take ages to pull significant amounts of data off the SD card through the serial/USB (about 72 seconds for each MB of datalog).

Actually it was released on Dec 31, 2012. We just didn't post on web forums until Jan 2.

I think this is how I'm going to do the MAP sensor. I can put the resistor and caps I need in there easily. This version of the connectorboard on the BOB doesn't have the proto area the last I had in my possession had so I'm just going to use the 12 pin connector pins, since I wont need it; I already have the spare 16 pin to populate with spares i/o's.







Here's the last one I had:

Is that what that extra circuit board is for? Ive spent the last year and a half second guessing myself for leaving it out. lmfao

High side driver circuit:



For use in 1.6 Miata, the fuel pump out pin goes to "VTEC Out from MS" and "VTEC Out" is your +12V to backfeed the fuel pump circuit.

Was kinda wondering how this was put into a DIYBOB board? I'm using a solid state relay instead... But this might be cheaper?! Not much though.

I do something different now: I just send the fuel pump out to 2O, then jump the corresponding pin on the AFM connector to the fuel pump relay.

Harness is 98% complete. I dont have written down my 16-pin connector pinout, so I need to go pull my harness and match up the wires.

I have my: 2 extra fuel outputs, two spark outputs, o2 IN, boost OUT, a spare 12v, ground, VVS IN, and knock IN.



Rough idea what the harness looks like:



I would have finished this a while ago, but I was slowed by the new connectors and the labeled wires which don't necessarily match the function of the ms3pro; yet?
