Waste spark config.

Post by johntramp »

Hi. I am attempting to get a waste spark setup running on
a 4age engine. I am not 100% sure what I have is correct
and would like it if somebody could have a quick look at this
setup.

I am using a CAS like this with a 4+1 wheel on the cam.
Setup as explained on this DIY Autotune page.

I am using a Mitsubishi igniter connected to the spark A/B
LED's.

Cheers.

If that's a 4+1 wheel instead of the 4+2 used on DSMs, set it to 4 base teeth, and set the trigger points to 1,2,3,4 instead of 1,2. Then enable dual distributor mode.

The wheel has one trigger per spark event on the first wheel, and then one trigger per 4 stroke cycle of #1 on the second wheel. Is that what you mean?
I guess it is 2+1/2 on the crank?

Cheers.

Yes, that's what I mean - a 4+1 wheel will need all 4 trigger positions set.

Ok cool. Cheers for that Matt, I don't think I would have figured that out myself.
