Hi Hotdog,
I wasnt planning on doing anything special with regard to checking the setting of the timing, was hoping to get something sorted so I didnt have to worry about synching the cylinders. chose the dyna 2000.with matching coils and leads etc. cos it was cheaper than the MSD
it does have the ability to have 4 preprogrammed advance curves in, and those curves can be modified by laptop if desired.
It also can synch cylinders 1&4 and 2&3 if you have a need to do that. Most of the 4 stroke cranks are well indexed unlike say 2 stroke cranks which are often 2 or 3 degrees out after a rebuild so wasnt planing to use the function. Dyna promote it as an ability to assist in temp control of middle cylinders but at this stage Ive gone from trying to be a hero to just trying to get to the other end of the lake.
Unless I have issues on the dyno I will start with timing off no 1 as usual, no index checking.
To find out the timing variation on the 4 coil power arc system I had to put a degree wheel on the alternator end and rotate the crank and watch for the spark to zap on each cylinder while observing the angle it fired. Discovered the 20 deg or more variation between 1&2 and 3&4 . It was hard at slow speed so I used an air drill on the crank end and a strobe light on each cyl lead
Interesting the unburned fuel in the exhaust made for real horny exhaust noise, pity it was so slow.
