MSefi.com read only forum (Jan.15,2018)

Id like to think that im not just throwing parts at the car, but my new plan is to run the ignition exactly as i had been running it on the carbed engine. I plan on picking up a crank trigger to isolate the efi from the ignition system. When the efi is up and running (and i get my second vehicle on ...

Thanks for looking, yea i know the msl didnt show much, i didnt think it was that important for tuning, mostly because i didnt know how to really read it...i understand the viewer better now though. i wish i couldve taken a log when it was running, i do have a video (not that that helps) but it ...

I dont have a recent data log of the issue...the only data log i have was taken on the weekend that it actually ran for several minutes. This is the current msq that i am running...i dont have a restore point back to what it was when it was running, but i see nothing that is wrong/different then ...

anyone have any ideas? I only get to work on it on the weekends, i need some backup ideas...any setting issues or anything to look at other then those wires. thanks

The light is approx 15yrs old, very basic light..there is a clip that goes over the spark plug wire, not a direct plug in...I had the exact same ignition system in the car for two years and had no problems whatsoever, the only thing that ive modified was the pull-up circuit and basically splicing ...

Got a new battery and am getting over 10v at cranking...im getting a spark, but i seems to have a 'roving' timing advance that doesnt want to stay near what it is set to (im using a different battery to power the timing light, so it isnt influencing the signal as previously stated)...thats one of ...

i installed c12, c30 and made sure that the input signal wire to the MS was completely shielded and i am still getting very weird signals ONLY when i have the timing light on. otherwise the tach and tunerstudios rpm gauge are very steady. I can get the engine to caugh over but that is all, nothing ...

Thanks for the reply, i did a few test and have come to the conclusion that my timing was off, BUT the TIMING LIGHT is causing noise in the signal... with the trigger pulled on the light the tachometer jumps up to 2000rpm when cranking...with the light off it seems to be giving true rpm readings ...

Well, i didnt fry the coil, but i havnt tested the Hyfire 6AL box yet-ive been bypassing it to try to get the engine going. What im confused about is what changed from last week to this week? Wiring is all the same, i dont know what could cause there to be no spark now...Im thinking that maybe the ...

...OK, now im not even getting a spark,im getting a cranking trigger from the distributor, but no output...I dont know if i fried the board or if its something stupid. Putting a multimeter to the + and - wires going to the coil: with the key on i get 12V, but while cranking voltage is going down ...

Thanks again Matt!

Im running a unilite distributor, since its running o.k. im not too worried about the input signal...i had also read about the going high vs going low output, that was the reason i started this thread. Ill try everything out this weekend and hopefully get it tuned well enough to ...

Thanks for the clarification, I was aware of the different codes, but not of their differences programatically. I am running MS II rev 2.90500.

As i had stated i had set the dwell and max spark to 25.5 but had also brought it down to 3.5ms and saw little difference between the two (granted i was ...

Thanks for the reply. I understand that must be the case since my posts keep getting moved...since im running MSII and have an ignition troubleshooting/tuning question about it i can see why i should be posting at MSextra.com instead of the forum titled EXACTLY what my issue is in ("MS-II Ignition ...

Anyone have an idea about the dwell settings at least?

Hello everyone,
after a lot of help and troubleshooting i finally got my car to start. I can barely get the car to run long enough to try and diagnose whether anything is wrong with the ignition, or if its just how far off my VE table is so...

The problem i am having is that it has a very unstable ...

Huh, thanks, that makes a bit more sense...i got the Dwell and spark set to 25.5 now. But can anyone else confirm that pin 24 goes to TACH on the relay board and pin 36 goes to S5? Also, are those the only two wires i need to connect for the MSD box and optical dist? it just seems like im missing ...

Sorry, just forgot to mention that i am unclear on the dwell and spark settings. Tunerstudio is telling me i cannot have a dwell greater than 8...im trying to search for why as you read this, thanks.

Hello everyone, Im at the stage of trying to figure out how to wire the car up. I have assembled my MS II and relay board already. I will be using my existing ignition: Mallory Hyfire 6al and Mallory unilite distributor-but of course controlling the advance/retarding by the MS. I want to make sure ...

Great! Thanks for your help! ...I do intend on running the electric pump, but it will be to a return style efi regulator, then thru another temporary cheap regulator to get the pressure from 20 to 5-7psi.

Hello everyone,
I am putting a MS II into my 1970 Duster with port injection. I Have just finished building my MS II board and everything checks out with the tests in the manual. The biggest issue i have with this conversion is that the duster is my only means of transportation, so i need to make ...
