ms3 with 36-1 cam wheel on V8
I have a Ford V8 that I have retrofitted with a Ford 36-1 wheel mounted on the camshaft. When I try to configure MS3 it gives me an error: number of teeth/cylinder mismatch.
Is there any way around this? Should I grind all the teeth but one off the wheel? I have a MSD distributor and 6AL-2 box. The induction is an ITB. I was hoping to run sequential.
Any help would be appreciated. P.S. I can't mount a 36-1 wheel on the crank.

Correct, 36-1 on the cam won't work on a V8, it gives 4.5 teeth per cylinder. 24-1 would work.
I can't think of any way to modify the existing 36-1 wheel.

Re: ms3 with 36-1 cam wheel on V8
Just curious: would it work to remove more teeth and make it a 12-1 wheel, with longer "gaps" than teeth, or does the arithmetic still come out uneven?

Re: ms3 with 36-1 cam wheel on V8
12-1 on cam = 12 teeth per 720 degrees / 8 cylinders = 1.5 teeth per cylinder = fail
36-1 on cam = 36 teeth per 720 degrees / 8 cylinders = 2.5 teeth per cylinder = fail
while
24-1 on cam = 24 teeth per 720 degrees / 8 cylinders = 3 teeth per cylinder = ok
36-1 on crank = 72 teeth per 720 degrees / 8 cylinders = 9 teeth per cylinder = ok

Re: ms3 with 36-1 cam wheel on V8
Thanks for explaining. I know it is in the manual, but have only used 60-2 and 24-1 wheels, so never bothered to learn about it.
Re: ms3 with 36-1 cam wheel on V8
thanks for the help. I'll cut off all the teeth but one.

That won't help either unless you also install a crank wheel such as a 36-1.pkm123 wrote:thanks for the help. I'll cut off all the teeth but one.

I thought I could use the VR off the distributor (MSD) for the main wheel (Basic Trigger) and the cam for the sync?

Re: ms3 with 36-1 cam wheel on V8
If you still have the distributor in place, then kind of yes. It work like a "dual-sync distributor" with "toothed wheel" mode. See the MS3 Hardware manual PDF.

There are these two stock Ford cam sensors.
