Unique Crank trigger wheel
Hello, I am intending to install a parallel MS3 + MS3X for sequential COP ignition control of an inline 6 engine. The crank trigger wheel seems to be very unique (yay for me). Does the MS team or community support coding in these unique wheel patterns?
The wheel is 60-6. The missing teeth are not evenly distributed; the pattern is 16-2-15-3-14-4-; where each "-" represents 1 skipped tooth.
The cam pattern is a 5v, digital signal, switching every half revolution. Since a picture is worth a thousand words, the waveform from oscilloscope is attached.
If, on the otherhand, I need to write the code myself, is the only file requiring a new if statement in the "ms3_ign_wheel.c"? Does any other code need to be adjusted?

No help for unique crank wheels?
I am compiling from code what I think is the right pattern for the wheel, but it won't sync with the engine. Any help on the other files that need to be modified would be appreciated.

Have you tried to do a composite log of the ignition inputs to see if you are in fact getting the signal that was showing on on the oscilloscope?

Yes, it appears correct to me. But I will try to get a screen cap/data log later today.bcrx7 wrote:Have you tried to do a composite log of the ignition inputs to see if you are in fact getting the signal that was showing on on the oscilloscope?

Re: Unique Crank trigger wheel
i managed to do this in the ms2 extra code

http://www.msextra.com/forums/viewtopic ... 91&t=37073
i was trying to get this added to the code
http://www.msextra.com/forums/viewtopic ... 25&t=50520
maybe it will be more succesfull now that someone is actually working on one
btw i tried to assemble the code with the latest ms3 but got an assembly error
and lost interest
i could do it again so someone could chip in
think it,s a memory space issue

Re: Unique Crank trigger wheel
did manage to do it with the 123 code
but got uneven triggers
look at the ms2 code triggers

Re: Unique Crank trigger wheel
you could try out the 1.2.3 code
as there is no camshaft defined
but at least you try if it sink up and possible run

i did it this way something about board quata been reached

Re: Unique Crank trigger wheel
Thanks MS2tester. I had developed a similar code. I haven't compared it to yours line by line though. We did some initial testing on my code and got it to sync. Unfortunately, we are now working on a different engine. We hope to get back to this one in a couple weeks. Please check back then on our progress.
