NOTE: Hardway Performance and Schober Motorsports do not offer any sort of delete tuning for any of the Cummins platform due to strict guidelines from the EPA. Please see the commonly asked questions below for further explanation.
First, get a list together of all modifications done to your truck. This includes, (but not limited to) any modifications done to the turbocharger(s), fueling, type of transmission, type of twin pump controller/splitter, rail pressure sensor details, map sensor (stock or aftermarket) and/or any specific CELs (check engine lights) that will need to be removed/disabled due to modifications (I.E. Removed grid heater). After this information is gathered, come on over to the website and fill in the blanks!
**IMPORTANT:
If you have a MPVI device, please pull a basefile and attach it above; MAKE SURE you also fill out the serial to the device as we cannot write the file without this!
If you do NOT have a MPVI device, you will need one. If you choose to buy one from us, it will ship without a file installed on it. You will need to pull a base file and email us the file and the serial from the device that was used.
The basefile is the file that is used from your specific truck that the tune file is written from! Also, processing time will begin at the moment a basefile is emailed to us. If you sent in a base file with your order, then the processing time starts then. Standard processing time from receiving your base file is 5-10 business days.
After receiving your file, use your PC and VCM Suite and upload the desired file into your MPVI device and flash the truck. After it is finished, attempt to start the truck. As long as it starts, the tune was successful! Congrats! You are ready to rip!
Cab & Chassis offerings will be coming very soon once further development is complete. This current tuning only works with 2500/3500 pickup trucks.
2022 and newer model years are SUPPORTED with a ECM replacement, please contact us if you have a 22+ that you are considering getting tuned.
Q: How do you change SOTF power levels?
A: Easy! You don’t need anything except your factory cruise control buttons. There are 6 total power levels (SOTF0-5) & you access these by pressing your cruise (Cancel) button and (RES+/SET-) buttons. When you first install the SOTF tune, it will default to SOTF0, if you’d like to go to SOTF5, press (CANCEL) 1X and then (RES+) 5 times quickly, the dash will ding while the lightning bolt flashes an appropriate amount of times for what SOTF level you’re on, so 5 dings = SOTF5. If you’re on SOTF5 and you want to go to SOTF3, press (CANCEL) and (SET-) twice, this will take you to SOTF3 and the dash will ding while the lightning bolt flashes 3 times. Also at any time you can press the (CANCEL) button without pressing anything else and the dash will tell you what SOTF it’s in. This sounds complicated but it makes perfect sense once you do it a few times in the truck.
Q: Will this improve fuel economy?
A: We wouldn’t expect any changes in fuel economy with this product. Although we surely know how to squeeze a few more drops of fuel per mile out of these trucks, all of our known methods also raise NOX emissions due to leaning out the combustion event, which is against the wishes of the powers that be so unfortunately our hands are tied. If you’re truly after economy our best suggestion is to stay away from the lift & leveling kits, big or aggressive tread tires, make the truck as aerodynamic as possible (say no to moose mirrors) and drive like you’ve got an egg under the skinny pedal.
Q: Will this increase regeneration events or hurt my emissions system?
A: We’ve seen no changes in regen frequency under normal driving circumstances. Think of your DPF as a big ugly filter that catches particulate matter (exhaust soot), if you drive stoplight to stop light with a heavy right foot, you can soot-load the DPF quickly causing frequent regen, this can be done regardless of if the truck is tuned. Lets say hypothetically you’re driving around on SOTF5 and flooring it from every stop light, you can surely expect to soot load the DPF quicker. Naturally diesels have smoke output especially before boost comes up, even though you can’t see it, your emissions equipped pickup truck is still “smoking”, your DPF however is catching it and processing it. In summary, enjoy the added power responsibly and you’ll notice no difference in DPF regenerations.
Q: Will this allow me to consume less or no diesel exhaust fluid at all?
A: This will not change the consumption of DEF whatsoever, the entire DPF/EGR/DEF subsystems of the truck remain fully functional as they were from the factory.
Q: Will this product allow me to remove my emissions components?
A: Definitely not, this is meant for all emissions components to be left intact and functional, no exceptions. Please do not contact us with your requests for this to be done, there are no secret codewords or passwords and we don’t care who you are, who you know or what you think about emissions regulations, we don’t like them either but our hands are tied and the answer is no.
