1st Tooth position

[smalcol]

Hi all,
Trying to determine the correct setting for my first tooth location. I am using a BMW M62 V8 engine with a 60-2 wheel on the flywheel. The sensor pokes through the bellhousing, I recorded a video of the teeth passing this point.

So, I started at TDC and turned the motor by hand counter clockwise. Counting the gaps, I get 12, including the missing two teeth. If I am understanding this each tooth or gap is 6 degrees and my setting should be 72 degress BTDC. Does that seem right?

Thanks in advance,
Seth

That sounds about right - try putting that in, disconnecting the injectors, and using a timing light to fine tune the angle.

Thanks, will do. I've never used a timing light with COP's. They sit right on top of the sparkplug in the head, is the signal from my coil driver enough to trigger the inductive light?

I doubt it, they are used to triggering off of tens of thousands of volts.

You need a plug wire, just one, pull the COP from #1 cylinder and connect the wire from the COP to the plug. Now put your inductive timing light on that wire. Watch where you lay the COP as you don't want the path of least resistance to be anywhere but the plug wire.

funnily enough my cheap timing light fires correctly if i put it round the 2 small wires (power and switch ground) on the denso cop my bike runs.

Wondering did this work for you. Im troubleshooting mine right now...as you know we have the same engine and 60-2 wheel only difference is MS2for me.

I already check for spark and had wasted spark C and B wired wrong but now I want to double check timing... we are sure the angle is infact 72 degree? for MS2 and MS3 is it setup the same? does the VR count after the 2 missing tooth or before?

the tooth1# is worked out the same between ms2 and ms3
