A PROPER ECM tuning MUST include mechanically fine tuning the fuel injectors and checking the cam shaft timing that opens and closes the intake and exhaust valves. in each piston. They co$t a lot because you're paying for the special hardware tools and software needed to do this job; AND the tech who performs this operation had to travel to the factory to receive special training. Its pricey, but its a qualified business tax write off. Assuming you write down your odometer mileage to calculate your MPG after each full tank, you should notice an increase in MPG fuel economy. If not, don't go back to the same shop.

PDI, Bully Dog, PP, Area Diesel, etc. I guess it is a hit or miss thing on whether they deliver what they promise. I have always wondered why they charge so much. Now the ones like PP and Area Diesel that offer add on control boxes, those parts do cost. But those that offer just a custom tuning of the ECM, why is the price so high. I did a custom tune, complete with paying for my tuner box, for my '06 Jeep Liberty Diesel that deleted EGR, increased power/torque, and balanced injectors for around $450. Yet the big truck folks want anywhere from $2000 to $3000 to do the same thing.

This leads me to another option. I just had my DDEC IV Series 60 tuned by Trent "Diesel Doctor". Actually I got it done by his sister at Walcott, since she does it there while Trent does it at Effingham. Got in there and balanced the injectors, upped the HP, upped the torque, removed the EPA Low NOx settings, streamlined the power curve. All for a whopping $300. And all future tweaks and changes are for free.

Will see how much the improvements make, but first results are interesting. To get a true picture, I am going to have to run this for a month and track fuelings to see how this plays out.

I started the day, before the tune, and fueled in Crawfordsville, IN. I ran to Walcott, on flat I-74, a 10 mph cross/tail wind, at around 62 mph. Nice, leisurely run. Averaged 7.5 mpg on the display. Then we did the tune at Walcott and I reset the mpg display. When I left there, I had a 20 mph crosswind, and running west, the rolling hills of Iowa, some which require a full power pull. And I bumped up the speed to between 65 and 70 mph. Results? When I got to just shy of Des Moines, I almost the same 7.5 mpg running that hard as I did running flat ground, slower, with a tail wind, same load, same fuel. If the run had been under the same conditions as earlier in the day, I would bet the mpg would have been over 8 mpg easily. The engine ran much more smoothly, and the response was considerably better. On the harder pulls, the EGT's never got over 750F. Minor changes on the accelerator netted better performance than before. This was a real pleasure to drive.

I would recommend anyone interested in something like this give Trent a call or stop in where he or his sister does the tunes. You can reach him at 217-994-1831. He is not going to try to turn an engine into a Pike Peak race truck blowing 1000 hp. He is tuning for maximum performance and economy. My 500hp 12.7 Series 60 got bumped up to 550 hp, and the torque got bumped up from 1650 to 1850. Nice performance bump without risking damage. They will tune CAT, Cummins, Detroit, Volvo, Mack and Maxxforce engines. What they can do for each, you need to check with them.

As a side note.... for those that have company trucks. A neat feature that most do not know is in the ECM is called "Driver Reward". It is a feature in a lot of ECM's. Just have to check to see if yours has it. Basically, if you reach certain criteria, you can go over the speed limiter. Trent can go in there and set the criteria to, say, 1 mpg. If you are getting 1 mpg or better, you can them go over the speed limiter if the driver reward feature is turned on, which Trent can also do. So there is your speed limiter override solution, without messing with the speed limiter. Have fun!
Ok, first of all, when you increase HP in a S60, say 10 percent, you change one parameter from 1 to 1.10, it is a multiplier. If you do not make the same change to the setting for fuel usage, the ecm will show 10% better MPG than you are really getting. You need to track it tank to tank.

If you are looking for a tune by someone that really knows his s$*%, go to the Diesel Dr in Little Rock, AR. Now he has trained ONE of the guys operating in Effingham, and to be honest I forget which one. And yes, I do some of this myself, for my trucks, and a couple select friends. Anyone that wants a commercial job done, i refer to Little Rock. Drive Safe!

EGR deletes are relativly simple in the ECM, but requires changing the turbo to really get an efficient engine.

I take back what I said above. Companies like PDI charge so much only because they get away with it. They will mess your engine so bad that you will think you need a new non-vgt style turbo because they screw up the vgt settings so bad. They delete several safety features that prevent the engine and turbo from exceeding dangerous specs. Just ask anyone with a PDI delete that has replaced several turbos and possibly engine head.

If the delete is done properly, you DO NOT need a new turbo. Nor do you need to fine tune injectors or check cam timing. The guys like Diesel Doctor that do it for far less might(?) actually know what they are doing.

There is an article about how to do your own delete to the Cummins ISX CM871 only. This is an extremely eye opening read even though its just for the 871. For more info on this, search for "Mama's EGR Milk Money" written by Rawze.

Uh, duh... I do check the fuel tank to tank. I also have a Scangauge D on the OBD port that is calibrated to reflect the actual fuel economy I am getting. The ECM stuff we all know can be very inaccurate.

But I am quite happy with the ECM work that I got done. Not even interested in getting anyone else to fiddle with it. It is like chasing your tail, you never catch it. I got great results for the cost and recovered any costs within the first couple of weeks. That is about as good as an ROI as anyone can hope for. Not sure if the one that did my truck was trained by the guy in Little Rock, and not really worrying about it. If I have the results I like, have been running it for over a year now, and I feel that sometimes it is just best to stick with what is working. I don't have the same mentality as Tim Allen.... "If it ain't broke, you can probably still fix it".

Iím going to agree with you guys that the diesel doctor is definitely worth a try he did wonders for me. The problem I had though is I apparently got lied to by a girl in a suv with a laptop in davenport she assured me that she was the sister of the "real diesel doctor" Trent she said. I believed her and paid 300 cash for my Detroit 60 for more power she plugs in and does her thing I get a hand written receipt, which is fishy to me. So I leave the next morning and I can drive faster but thatís all I notice still dropping gears same fuel mileage I try to call her and no answer after 5 or 6 phone calls I just say f### it I got screwed. Couple weeks later I'm in Effingham so I stop behind Hardees there at the petro exit and I see a grey trailer with diesel doctor on it so I go and explain I didn't get what I paid for. He laughed and said let me guess a person with a laptop in a vehicle cash only and now they won't answer. He said we get this story a lot. He then explained he sued that group and that they are still apparently able to survive by suckers like me. He plugged in couple mins later he said give that a try boy could I tell the difference I gladly paid him he said please spread the word against these imitators out there he showed me his trade mark from 2002 and he owns the lot he sits on. He is the real diesel doctor and stands behind what he does anyone looking for the real diesel doctor be aware the only one is in Effingham behind Hardees at the 159 anyone else is a imitator Iím a avid forum believer in getting the truth out here in this trucking industry I'm so mad that there are people out there low enough to lie and take my money without batting a eye I will post this everywhere to let the truth be know that the real diesel doctor is Diesel Dr. Diagnostics - Auto Repair Shop | Effingham, IL and hope that I can help detour anyone else from also loosing their money to those imitators

Guess those other guys have to pay for all the truck stop rag advertising and such.
Just talked to DD to reprogram my ECU and he said $350 than when I told him about EGR delete the price just jumped to $1500. I'm not sure if he did it for you just to have it advertised or what but hes right there with the other guys on the price.

You have to keep in mind, I had mine done two years ago, see the first post date. I am sure the price went up for basic ECM work. I have no clue on the EGR delete stuff because I didn't have EGR on my 60. Truck still doing great.
