Gentlemen: How exactly do you measure how far off the correct position your trigger wheel is? I'm about to start reprogramming (really have no idea how to determine the optimum values for my engine but that's another question)
In the Operation guide global setting window (4.3) it seems to expect me to know how far off the trigger wheel is and to enter that value... or when I start up the engine, will the MJLJ system magically measure how far off the wheel setting is for me?
This seems like a silly question to me but I'll ask for forgiveness later...

Basically you start the engine without the mjlj connected, so in limp home mode respectively. Then by using a timing light measure the timing off the timing marks on the engine. It should be at 10 degrees BTDC (Before Top Dead Centre) if its not then you just need to correct the trigger offset when MJLJ is ooperational so it is.
This will then ensure that what ever value you put in the table then you will get the exact value of timing.
You should be able to spot the trigger wheel to within approx 5 degrees with a keen eye, then you can just program the error out with the software.
Hope this helps
