Default MSPNP v3.57 Upgrade Help to MS2

So I recently bought a MSPNP v3.57 for my 94.

Its been great and I got the car all tuned up, but I went ahead and bought the MS2 daughterboard to make better use of my AC. I have read multiple threads in which many state completely different approaches other then replacing the board to upgrade. These are my goals.

I essentially want to continue to use my current set up.(on my MS1 board) with the addition of the idle up feature for my AC. From what I know the MSPNP I bought used on here has not been modified by anyone other the DIYAutotune. Everything works as it sits with MS1. I just want to upgrade to have better use of my AC. Attached is a picture of the jumpers if it helps at all. I have not touched anything other than opening the case. I want to do this right and not **** up an already decent set up. I am pretty good a soldering I just dont want to put the wrong jumper on the wrong spot.

Any comments or better yet help is always appreciated.

So I went ahead and took some initiative and jumped the s12C with js9 and removed the cap off of the mapdaddy. This is preety much what I am sure off. The rest I have no idea what it could be wired for or if some of the jumpers need to be relocated or if I even have any extra features installed.

Yeah. I found a post from a while back that I will post later today of a guy who opened his ms2 he bought from diyat and he has pictures and written the layout of the jumpers. I tried using the wikidot but it seems rather bare when it comes to info. I read the manual too and looked at other post but I'm sorry even though the 3.0 and 3.57 boards are very similar there are areas that are very confusing when comparing the two.

Calling for MS Gurus - Help with MS2 SMD v3.57 installation - Miata Turbo Forum - Turbo Kitten is watching you test compression. Ok so I have done all the wiring similar to this guy and still nothing. I am going to play with the fuel settings as I may be too lean but harware wise I have updated my megasquirt similar to his

Well I keep getting denied when uplading for some reason but here is the updated progress on what I have done

Here

https://www.dropbox.com/s/kg7s75feflv9c8w/IMAG0147.jpg

and here

https://www.dropbox.com/s/gu40ljpj67u2djn/IMAG0148.jpg

I noticed that I am missing the transistor that go on q16. Which happens to be VB921 dedicated coil driver chip. So I am thinking I need that soldered in and i might have some luck and gets this ****** started.

EDIT: Found this Bosch BIP373 Coil Driver Mod Kit DIYAutoTune.com going to probably go ahead and get it and I am hoping it will fix my problems.

that's not the issue. The crank and cam inputs (pins 24 & 25) need to have the polarity reversed when on ms2 from ms1, did you do this yet?

also, can you use something other than dropbox for your pics? that's not really the correct useage for it and they dont show.

I've been on vacation the past couple days, and it looks like Ben and Russ were pretty slammed. I just emailed you back a list of jumper changes. Note that it doesn't include the A/C idle up feature on the GSlender or 3.3.x code; we haven't tested these on a Gen 1 MSPNP.

Fixed sorry about that





And

I am not sure the best approach to switch the polarity of pins 24 and 25 when my DB 37 is integrated into the board and then into the Plug and play for the harness.

I received an email from Matt with some assistance. I am going to go ahead and when I get home follow this spreadsheet and see what I get.

Thanks Matt,

I appreciate it, I am going to try this when I get home tonight. At this point I just want the car running on MS2 and then I can see about the Gslender implementation. I updated the firmware to 3.2.1 so it can correlate to the base tune on the website. I figure I will keep it as bland as possible and get it to start first.

So this is where I am at all my gauges seem to be working. Still no start here is pictures of my wiring that Matt sent me. Ignore the yellow I ran out of red wire. I am also attaching my first attempt at data logging and the .msq file I loaded from Diy's website.

JP1 is the 3 pin header next to the DB37; was that set correctly? You don't seem to be getting RPM.

I put in the stock MAF and ECU and started it up to burn all the extra gas from all the FAIL. I then unplugged the coils and re flashed the ecu firmware and it flashed just fine. I burned the base map again and still no start still no tach signal. I still need help on wither or not to reverse the polarity of pins 24 and 25 and if so how. I have been reading and reading and still nothing on how to approach this on a v3.57 board. Trying to get this car started has been my LIFE lately and the Mrs is probably going to want a divorce after LOL. Once I get it to run I am going to do a write up for v3.57 MS1 users upgrading to MS2.
