60-2 Pattern for GenIV GM LS engines

Postby 5.3LS10 » Sun Feb 07, 2016 7:22 pm

Will the 60-2 pattern (Sw4) work for simulating a GM LS Gen IV engine? I do not feel that the cam signal is correct but I want to verify that before I make any assumptions.

I know the crank pattern is a 60-2 pattern but the camshaft is a 4x and after reviewing the wheel pattern code it does not look to be equivalent to the 4x.

The reason I ask this is that I have a cam fault in TunerStudio and have gone through all the documentation to make sure that I have everything else configured correctly and have came back to the JimStim might not be outputting the correct wheel pattern.

Thanks,
Shane

The cam pattern for the 60-2 signal is a simple single tooth pattern.

Thank you for the response Jean.

So that would answer my question that it will not do a GEN IV LS Cam sensor. I will see if I can rewrite the pattern and make it work.

The MS3 documentation tells you to check at tooth 20 which 360*/60 teeth is 6* per tooth so tooth 20 is at 120*(of second revolution)

Thanks for the input

So it is actually the first revolution. I also ran into an issue where the cam sensor signal was slightly delayed (confirmed with composite logger) that it was not picking up so I made tooth 19 high as well and it worked! I will post up the pattern for anyone interested in using the 60-2 pattern for a Gen IV LS engine.
