i just did the injector test mode this morning and they do work but now i m stuck in this mode , i will have to reflash MS to get out of it.

They ' ll probably fire in injector test mode cause if i enable auto-trigger i get injection and i m able to start the bike but its very hard to start that way
cause cranking rpm is jumping around from 200 to 700.

Hi there,

ive been playing around theses days with the dual tach input settings to try and control spark on my bike. Used to run fuel only via "the trigger off a negative side of coil".

i have microsquirt V3 and trigger setup is one teeth on crank for 2 vr sensor 180 deg apart from each other ...

ok im starting to get good results here but there is so much confusion about my understanding of the manual and how MS handles spark calculations for my setup.

1- Since in dual tach input mode M = 0 :

-how does MS knows the engine position and fire at an accurate position if there is only one ...

i tried different variation including what you told me to which is exemple #2 on this picture.

on exemple #2 , vr2 was connected too but signal didnt show up on tachRef thats why it only shows one signal.

Still no offset showing in tachRef , but i guess that its how tachRef ...

Update :

ok so now i got a signal like this on tachRef

Why cant tachRef see the 180 deg offset that seperates both signal like i see in my oscilloscope?
I mean in the picture they dont look like they are separate equally like an even-fire would be...

ok thanks !!

heres a pic of my VR1 wiring:

I used 1N4004 diodes which are rated for 400V i believe.

SO in the morning i wired up like this , only using VR1 and check the tachRef which gave me a nice reading , i tried it twice and worked great.

I was very happy and felt excited but ...

i ll try that tomorrow but what do you mean by "power GND"?

For the tachRef i showed at the begining of this post:

stock VR1 sensor+ to MS VR1+
stock VR1 sensor- to MS VR1-

stock VR2 sensor+ to MS VR2+
stock VR2 sensor- to MS VR2-

**note :stock VR connector was unplugged from the TCI unit.


For the latest tachRef :

VR1+ from MS and VR2+ from MS are left ...

i did another tachRef and here s what i got:
i dont understand why there isnt any offset from Vr2.
