Crankshaft reluctor wheel teeth?
Anyone know how many "teeth" are on the crankshaft reluctor wheel that the crank position sensor gets info from? Are there differences between a 2006 or 2007 motor in this aspect?
I found this info, "Early LS engines mostly used 24-tooth wheels and upgraded a few years ago to 58-tooth". Not sure if it applies to us and if we are in fact 58-tooth on all LS4 motors for all years. I have found that 2006 motor uses a different part number for the crank position sensor vs. a 2007 motor.
Thanks!

07, but not all. The easiest way is to just check your PCM, E40 old/ 24 tooth. E67 new 58 tooth.
One easy method is to look for the MAP sensor, E40 has it in manifold neck at the TB, E67 has it towards the rear of the manifold.

Lingenfelter has a box to fix that I guess.

Some people have had issues using it though.
