Discussion and questions related to the course Practical Diesel Tuning
Hello! I want to start by saying I have enrolled and completed your diesel tuning course and I thought it was great and very detailed. I have a 2012 Ram 3500 6.7 cummins with 68rfe transmission. I had purchased a EFI live autocal v3 from dpfdeleteshop.com with the 5 tune switch. My truck does have the egr and dpf deleted. My truck has a knock at low load and cruise which I believe is from the pilot injection tables being out a little. It does is on all 5 tunes. 20,40,60,80, and 100 hp tunes are what I am suppose to have. Here is where I run into trouble because the tunes are locked and cannot be viewed or modified from the tuner. Now I did do the unlink the process thru efi live. I do not have my stock tune files. I should have saved them before loading these tunes into my truck and that is 100% my fault. I am use to other tuners that store stock files to return a truck back to stock. Is there anyway I can purchase a tune from you that is egr and dpf deleted that I could modify myself or is there anyway I could purchase custom tunes from you that are in the same 20,40,60,80,and 100hp range that can still be modify and have already been egr and dpf deleted? Any and all help would be greatly appreciated and I do not expect anything for free. I am a diesel mechanic by trade for the last 15 years and want to start getting my feet wet in the world of diesel tuning. Don't get me wrong my truck runs great with very little smoke haze on the highest tune but is a little noisy I believe. Truck is in great shape with only 59,342 miles on it and only 1990 engine hours. Its still a baby. I do have the Banks cold air intake on it with the upgraded boost and charge air tubes and the monster ram air intake. Bare bones on the truck are all else relatively stock. Stock Injectors and stock transmission with the upgrades transmission case brace and deep sump pan. Thank you again for your help
Thanks for the support and appreciation around the course material.
Regarding your 2012 Ram, I have a couple of suggestions. First, I would start logging the truck using EFILive with the cummins EDA PID group. This should give you a great picture of what's going on as you drive the truck. You'll certainly be able to tell if the pilot event/quantity is associated with your noise or if it's related to fuel pressure/Timing.
Second, I can not offer you delete base files. I would imagine there's somebody out there still willing to risk the associated legal problems of that business but I'm not. Sorry I cannot be more useful here.
as a tech I would also wonder if you have a leaking injector. A single knock is usually an injector. If it sounds metallically on tip in and part throttle I have learned that its too much timing... I would eliminate injectors by using a block off tool and see if knock goes away by blocking off one injector at a time. As a suggestion.
