MSnS Timing

[jacob80]

Ok guys,

 

Soon I'm going to attempt to lock in my physical timing. Before I explain my proposed procedure, I do have a question. We have a performance products pulley and it has multiple tick marks. In addition to these tick marks, there is the timing tab that has the tick marks that max out at 30 degrees BTDC (correct me if I'm wrong) therfore introducing two variables. Shouldn't thereo only be one timing mark on the pulley? Which timing mark on the pulley represents TDC per say? Ok anyways, here is my procedure:

 

1. Turn engine back to ~50 degrees BTDC

2. Loosen distributor and lock it down when light comes on

3. Crank engine and see if timing light/timing tab/pulley marks agree with cranking value in megasquirt.

4. If they don't agree, adjust the timing inside MegatuneSS until its right.

 

Ok so does this sound right? Once I confirm the timing on the pulley and the computer agree, i don't have to mess with anything else other than the computer settings correct? Thanks guys

Or you could just TDC the motor per the FSM. That would be aligning the can marks. Then mark the damper with a paint pen or white-out.

I agree, only use MS to fine tune the timing if you can.

 

You should be able to find TDC using the 0 mark on the pulley/timing mark.
