Cummins lope?

[DRD]

Making a Cummins lope is silly proposition. I've done on it my truck just for the heck of it but I don't care to use it. I'm 40 and don't care for such anymore. But for anyone that does, all a lope is just having the fuel to shut off and on at idle and the low rpm ranges. Mechanical injected engines do it when the timing is cranked really high. What happens with high timing is that engine will want to rev up with fuel flow so the governor goes into a battle of shutting the fuel on and off to maintain a consistent low rpm setting. That makes a fast low rpm surge or lope. With computer controlled common rails, its just a matter tricking the ecm to shut the fuel off and on really fast in the desired rpm range to make it lope.

Sorry brother. You'll just to go through trial and error just like I did. You have the basic idea in the quote above...that's all the hint I can give. I make a living at selling tuning. You can't expect me to give my intellectual property away.

Over time I wouldn't be surprised if there isn't more self tuning enthusiasts like a few of you already are on here. Now that could be some interesting discussion. But ya I agree with Ray on secrets to his livelihood. Good luck though.

Yeah I'm wanting to learn tuning just for my own interests but honestly I have no idea where to even start. I understand bits and pieces of it but I'm wanting to understand it completely so I can put all of that knowledge into a tune . Since I'm on this topic do you know of any way I can learn this? Books, websites, etc?
