odd issue with ms3x + d14 to igbtin in and ms3 outputs

Post by baz-r »

i have a bit of an odd one here with my fresh built ms3x in testing with jimstim v2.0.3 and jimstimx 0.2 fitted
i needed to drive a high current wasted spark coil directly on a 4cyl in my car so i did the old 2x bip373 off D14 and D16 mod and tested without the ms3x card fitted (all good) then i fitted the ms3x card and tweeked the settings for testing only after fitting the ms3x card with both stims conected to check cam trigger and outputs etc (8x spark, 8x inj on card) but i get a odd problem/effect i have no set output on d14 but its running d14 with the rpms and not in time with any the ms3x coil outputs (faster like its working a coil normaly in a dizzy setup) where as d16 stoped running when i switched settings over to 8cyl off ms3x drivers in tuner studio?

any idea if its hadrdware or code problem or me just making an dumb error?
im not using the coil outs on the ms3x for coils at the minute but want to prove my build and dont wand problems in the future if i make mods or usethe coil outs on the ms3x card for other things in the future (or vice versa)

Sounds like D14 is operating as "Squirt" which is what it will do if you have the spark outputs somewhere else.

It's pulsing once in time with every spark or injection output but as I have the ms3x set for all injection and coil outputs

It's the fact that I have no output shown in ts on D14 it's was making me think I had something wrong

baz-r , I know this thread is 2 years old, but hopefully you may remember some details of this build that may help mine:

When you had the BIP373 wired to D14, did the LED stay on initially when the MS powered-up, then flashed once the rpm synced?
thanks.
Want a neat way to Check & Set Ignition timing AND CRANK the motor at the same time BY YOURSELF?
