Cam teeth setup?

[Borgli1]

So I figured out all my info when it comes to cam and crank degrees. I can see where I need to enter Tooth 1 degree BTDC but where do I enter all the info for the CAM? The trigger on the cam hits the sensor at 330 degrees btdc or -30 tdc.

Also, my cam has two teeth on it, one is about 100 degrees of from the other. Do I have to remove it?

Thanks!

Basic info:
MS3 Pro
VR sensors
60 - 2 trigger wheel

If you are not using variable valve timing, for a cam with two teeth, you would use "poll level" mode and specify which crank tooth the cam tooth lines up with.

I am planning on using VVT, but that is just the intake. The teiggers are on the exhaust. Im betting there are two because the var had two ecus one for each row og six cylinders.

Do you have diagrams or photos of the cam triggers? It's rather tricky to guess an answer otherwise.

I'll just remove one of them instead of finding a way around it. Thanks guys!

One last question.
Where do I input the can degree in the software? I can only find tooth #1 BTDC for the crank

[jsmcortina]

You don't.

Read the Hardware manual for your product and see the diagrams for phasing the cam and crank wheels.

I have read all og chapter 5 in the ms3 pro manual, but my dyslexia is screwing with me. Making it hard to wrap my head around it.
There are diagrams of the engine being rotated forwards and backwards to find tooth one degree and to find when the cam trigger passes the sensor. I just can't make out what to do with the info.

"5.3.4.8 Missing tooth crank wheel and single tooth cam wheel This is an very common arrangement that supports full sequential and coil on plug. (For 50/50 type polled cam wheels, see the next sub-section.) The definition of tooth#1 is the same as the basic missing tooth crank wheel and should be phased in the same way. Ensure you also read the section above. The cam input tells the code which engine cycle/phase it is on. From the crank wheel alone, the code knows when cylinder one is at TDC, but it cannot distinguish TDC compression or TDC exhaust. The cam sensor adds this information, which is why it needs to be one pulse only per engine cycle. The cam signal is a single pulse, usually generated by a narrow tooth, vane, or window. Technically, it is edge triggered. For VR type sensors, the edge setting will depend on the wiring you use (typically Rising) as the signal is a very short pulse. For a hall type sensors you need to ensure that the edge you choose matches up with the phasing as below. To confirm correct cam sensor phasing proceed as follows. First, set your engine at TDC compression #1. Nowrotate the engine backwards to tooth #1. The angle read off the damper is the tooth#1 angle. Now rotate the engine backwards some more, at least one or two teeth -this is the best place for the cam tooth to pass the sensor, if you are retrofitting a trigger setup. However, the cam sensor can be at any angle except having the active edge aligned in the tooth gap."

[Matt Cramer]

The code does not try to "pin down" the cam angle, as this can move by several degrees if you have timing chain stretch issues. Instead, it simply checks "Has the cam signal arrived before the missing tooth on the last crank revolution?" It doesn't matter WHERE it arrived on that revolution at all.

Makes sende! Thanks for clarifying.
I almost got it started last night, but one of the cylinders got flodded. Now I'm just hoping nothing broke, gas came gushing out when I turned it wit the sparkplug removed.
