  1. Sticky: You would still need to figure out all the...

    You would still need to figure out all the checksums. Every command you send would need to have that on the end of the command string.

    Post a picture of each injector's bar code and I can generate...
  2. Sticky: Even with the wrong injectors the engine should...

    Even with the wrong injectors the engine should still start. If it won't start then the problem is elsewhere, likely a faulty EMM. The C89 capacitor is a known failure item in the EMM and the likely...

    I'll certainly be buying a GPS module for the MSX and maybe one for the FXHO if I decide to keep it.
    What is the projected cost of the Polaris software?
  4. Sticky: Not to steal anyones business, but I posted the...

    Not to steal anyones business, but I posted the information on how to run Digital Wrench, and now the information on how to DIY all the EMM programming. From the 8 pages in this thread, I've only...
  5. Sticky: More updates... Found out that all my changes...

    More updates...

    Found out that all my changes were not there after going back into the EMM. Previously I sent the commands and confirmed them with DW, but *didn't power down everything* and...
  6. Sticky: I think "He" is me. The barcode is called...

    I think "He" is me.

    The barcode is called "DataMatrix" there are various encoding schemes for them, or error correction to be more precise. The older injectors were ECC140, an older method that I...

    Keith, can we clean out all the 'extras' from this thread and make the EMM data portion a sticky?
  8. Sticky: I'd be interested in seeing what the part numbers...

    I'd be interested in seeing what the part numbers are on the Carter pumps inside the housings.
    I thought the Weber motors ran around 50psi. When I clamp my return hose I get 50. Normal operating psi...
  9. Sticky: I did verify accuracy of my gauge. It's good to...

    I did verify accuracy of my gauge. It's good to at least 1-2psi accuracy.
    It does get up to 50psi when the return is fully clamped off. I suspect the fuel pumps for the MSX110/150 are identical with...

    Cheap harbor freight gauge. Probably not very accurate.
  11. Sticky: Problem is with ski 2. Last week it wouldn't...

    Problem is with ski 2.
    Last week it wouldn't fire the fuel pump. Took the EMM out of ski 1 and tried it in ski 2 and the pump worked.
    I did remove the logic board from the EMM case to have a look,...
  12. Sticky: Yeah well now maybe a few Polaris' will be back...

    Yeah well now maybe a few Polaris' will be back on the water where they belong, and not in pieces on ebay.

    Some of my best work comes from the NEED, and being too cheap to spend $400 to have Ghost...
  13. Sticky: Confirmed. Injector serial numbers and...

    Confirmed. Injector serial numbers and coefficients have been loaded. Engine sounds much better. Still has 2-3yo fuel in it, and the damn FPR must have fallen in the tank.
    This is on "Virage 2",...
  14. Sticky: No worries there. I was an Electronics Technician...

    No worries there. I was an Electronics Technician in the Navy, and know 2M repair. I already figured something, probably a cap as you said, would be bad. No harm in trying.... so long as there is a...
  15. Sticky: I actually just got it out of my fathers attic...

    I actually just got it out of my fathers attic this past weekend so he could sell the house. It's been up there since the mid 90's. I didn't even try to power it up, and just put it in storage....
  16. Sticky: I got my start with CP/M - the predecessor to...

    I got my start with CP/M - the predecessor to DOS. It was on the very first portable PC, the Osborne Executive - about the size of a carry on suitcase. And I'm only 36.

    I design networks, and...
  17. Sticky: Here is what I have come up with to write my...

    Here is what I have come up with to write my injectors into the EMM. I'm at work right now, so I can't test until later, and it's also why the serial number is 1-7. I'll correct that later. Also...
  18. Sticky: Ill be doing that tomorrow night. I already...

    Ill be doing that tomorrow night. I already mapped that out in a previous post.
  19. Sticky: I just successfully changed the serial number in...

    I just successfully changed the serial number in the EMM of my MAG injector!
    I have it all figured out now. The conversions to DIY are not fun, but the only thing you need is a diagnostic cable...
  20. Sticky: Bravo! Looks like I overcomplicated it. Sad...

    Bravo!
    Looks like I overcomplicated it. Sad thing is, I hate math, and generally suck at it.

    I can't wait till I get some data dumps of writes. I'm going to try and clone an EMM to see if I can...
  21. Sticky: Yes you are right. Too much thinking all day at...

    Yes you are right. Too much thinking all day at work with IP address and subnets, then to come home and sort this out. I'm a bit fried.

    Hope I'm on the road to paying you back for that .dat file...
  22. Sticky: Figured out what the last bit is. A checksum for...

    Figured out what the last bit is. A checksum for the previous bits.

    01 10 00 00 0D 14 00 00 0A 32 00 00 04 1D 00 00 51 7C 5C

    Take the first 17 bits and convert each hex code into a decimal...
  23. Sticky: I also suspect that the "01" preceding each line...

    I also suspect that the "01" preceding each line is a "read" request. I'm thinking a "write" request will be an "02" or similar.
  24. Sticky: Made some progress decoding the data today. Not...

    Made some progress decoding the data today. Not done yet my eyes are tired.

    My injector data if you want to follow along:

    Serial # - 03134040123564
    A-1648
    B-1116
    C-677
    D-23173
  25. Sticky: Had a thought.... I think that copying all the...

    Had a thought.... I think that copying all the data from one EMM to another includes the injector data as well. I'm going to try to write all data to another EMM and verify the coefficients moved...
