Hi Jim. You got me thinking. Understand people intentionally vary cam timing to suit their needs. Am I understanding that correctly. If so and like you said the curve would change but never look like mine meaning something is totally wrong.
Please someone with real world experience jump in here but if I move the timing +/- 6 degrees it will NOT devastate the curve like that in the simulation model. Your curve is totally crazy. All it really does is shift the peak around, it does not make it collapse like yours does.
