60-2 crank pickup on 5cyl audi??

[83quattro]

I'm currently planning a MS'ed 2.5litre 5cylinder audi engine for my 4000q, and I vould HATE using the distributor for ignition pickup.

Is it possible to use a 60-2 crank wheel and a MSD 6 CD unit with a single coil. distributing through the original 5-way dissy?

I can't see why not ( 60 / 5 = 12 ) .

Am I missing something fundamental.??
I realize that the coil will fire 10 times / 720 crank degrees, but I think the MSD coil will still perform better than the original (remember, no boost)..

Please enlighten me!!

I just realized that the dizzy will be out of phase for one of two sparks.
to make this work the MS must fire on every 24. tooth. ( 5 times / 720 crank-degrees).

is there a 10cyl edis ??? (worst case senario)


I really need to work out the setup so I can order the parts.
The car arrives from the body-shop in less than one week.
It would be a waste of summertime too run out of work before the engine-parts arrive.(or even ordered.. )

please help!!!!

Using MS1/Extra, the 60-2 wheel and a single window dizzy as cam sync you should be able to run distributor spark or COP if you wish.

So the MS II code does'nt support a 60-2 wheel (even beta) ?

"Coil per plug can be achieved with a crank wheel and single-tooth cam wheel OR a dual wheel cam setup OR a missing-tooth cam-wheel alone."

According to the MSnSe thread, I should use 60-0 wheel at the crank and a single tooth wheel on the cam, or a missing tooth wheel at the cam,, but why not at the crank??

I'snt the missing tooth to reset the teeth count? Why do I need two wheels?

Sorry if my questions seems stopid, but I have dificulties understanding the need for tw wheels. (I'm keeping the dissy for now, so no problem, but I need to understand this fully before ordering)


Thanks for the input. Great Forum!!

5 cylinder COP on MS1/Extra ?? Is that possible ??
Wasted spark is not an option (uneven no. of cylinders)
I just want to use a more acurate trigger than the distributor hall sensor, does'nt really matter if it's COP or a single MSD coil,using the stock distributor cap and a crank/cam trigger.

I would prefer using MS II, but MS1/extra could do.

Can I use a even 60 tooth crank wheel, and a single tooth cam wheel + the distributor cap for ehh.. distributing?? remember, It's a 5cylinder engine!

A lot of questions, but if this works out, I'm ordering 3-4 kits for testing with the local Audi club. Better order the right thing!! If not, I guess they will go for 034EFI. Not a bad word about their kits, but not nearly as inspiring and educational as MS. (as I am car,pc AND solder-experienced)

Summary: How to get a vr crank or cam trigger to work on a 5 cylinder engine? (can use distributor cap for spark routing) preferrably with MS II

The 60-2 wheel + msd, distributor should work with the MS II beta code (v2.672x7b). If it is set up to fire once every 24 teeth, the dizzy should take care of the routing.

Thanks a million times!! That's all I need to know!

Even with a distributor, with only crank trigger, how do you know it's not going to be 360 degrees out of phase? There's something I'm not getting here.

The distributor only rotates once per 720 degrees of crank rotation. The rotor is always only pointing at the cylinder in the compression stroke.
