The challenge would be to find out what cycle. Because without knowing which is the true ignition stroke, it would start 50% of the time and be wrong the other 50% of the time.I don't know the software, but that seems something very-easy to program to work every-other cycle.
I`m wondering how you set it up. From what I read on other forums by birdoprey, this is the firing order of the Vmax:Well I'll add my 2 cents to this really old thread. While the F.I. sounds great as there is no more adjusting the carbs, the FI systems has the same issue. I had the Wild Bro FI on my bike for a while and I always had to travel with a tablet to do adjustments. You need to drill and weld a bung on your exhaust for an O2 sensor. You need to drill and install a fuel pump on your gas tank. You will need to dyno the bike to set up the base configuration. The FI system ran really rich and was hard to get that magic 14.7 -1 ratio. I never was able to get a nice curve but generally it performed pretty good. I'll see if I can find the dyno but I was able to get 120 hp out of with a kerker 4-1 with the small baffle. Unfortunately, unlike your car, this was not a set once and forget system.
*Cyl #1 fires, then the crank rotates 70deg
Cyl #2 fires, then the crank rotates 110deg
*Cyl #3 fires, then the crank rotates 70deg
Cyl #4 fires, then the crank rotates 110deg
Cyl #1 fires, then the crank rotates 70deg
*Cyl #2 fires, then the crank rotates 110deg
Cyl #3 fires, then the crank rotates 70deg
*Cyl #4 fires, then the crank rotates 110deg
*Cyl #1 fires(back at the start)
The "*" indicate when that cyl is TDC on its compression stroke(power stroke)
So next to squirting only on the correct stroke, you have to time the fuel injection correctly per cylinder. Since the V4 is configured in 70 degrees V instead of 90 degrees, the injection moments have an offset in timing as well.
Were you able to configure both correctly with the Microsquirt? If not, that might be reason why you ran rich and weren't able to make it run autonomously as it in theory should be able to.
