The EECU works the same between the Jake and the Power Leash correct? -

Jody Scott replied to Jody Scott's topic in Engine and Transmission
My thinking is that both the Jake and Power Leash work the same it is just that the Power Leash does it better. Nobody that I have read about or come access has been able to explain why the Power Leash works better other than being designed/ engineered to work with low volumes of oil. -

So basically you need a cam shaft, rocker shaft assemblies, EECU, valve covers with the stud for the engine brake celenoid, high volume oil pump, rocker shaft bolts,, thats all i can think of of the top of my head. As far as cam timing, im not sure if the EECU will take care of that, or if you will use an offset cam gear key. -

Personally never done it possible maybe! Programming may be an issue? If you remove the exhaust you’re putting more oxygen in leaning out the burn likly making more heat timing maybe an issue!

I was looking at that the cams part the other day and I was scratching my head over it. A cam normally is just a question of lift and duration but Mack has a strange grind on their cams that causes the valve train to get loose on the back side of the lobe, i dont understand why they do that but i dont think that has anything to do with the operation of the engine brake. They even put springs on the push rods to help with keeping the noise down on the valve train and other reasons i guess. So with the cam and engine brake operation it comes back to lift and duration on the exhaust lobe right? Don’t get mad at me over this, i am just trying to understand how and why this can or can’t work.
