2011–2014 New Holland T6–T8 Tractor DEF Delete Tune

Tier 4A T6, T7 and T8 tractors were among the first New Hollands to run on DEF, and their dosing pumps, heaters and NOx sensors are now well past their prime. Our Reflash Master handheld switches off the DEF/SCR system straight from the diagnostic port, with no extra hardware and no change to the exhaust. Load a horsepower tune at the same time for up to 20% more rated power. We ship all across the US and Canada.

Why delete the DEF on a Tier 4A T6–T8?

DEF

Diesel exhaust fluid

A T7 on the baler or a T8 on the air seeder can burn through a lot of DEF in a season, and every tote has to be bought, stored and kept clean. Fluid left in the tank over winter breaks down and leaves deposits in the pump and supply lines. On these early systems, poor-quality DEF is one of the most common reasons for a derate. With DEF removed from the software, the tractor runs on diesel alone.

SCR

Selective catalytic reduction

The 2011–2014 T6 to T8 tractors meet Tier 4A with SCR alone, so the engine controller keeps a close eye on every part of it. Ten-year-old NOx sensors, line heaters and dosing modules fail often, and each one can set a code that cuts power mid-job. Parts for these early systems are costly and sometimes back-ordered. The reflash takes SCR monitoring out of the file, so a failed part can no longer limit power.

More power from the same hardware

Within each Tier 4A series, New Holland used one FPT engine family and set each model’s rating in the calibration. A T8.275 and a T8.420 share the same 8.7 L block, and the T6 and T7 ranges work the same way. That leaves headroom a custom tune can use safely.

01Calibration sets the ratingFrom the T8.275 to the T8.420, the hardware is shared and the file is what changes.
02Up to 402 rated hpA Stage 2 tune takes a T8.390 from 335 to 402 rated hp.

Frequently asked questions

Q1Why choose Reimer Tuning for my Tier 4A New Holland?+

We write every T6, T7 and T8 file ourselves, built from your tractor’s own ECM read. Files come back in about 2 hours with a 1 year software warranty, and you can call a tech if you need help while flashing.

Q2Does the exhaust need any changes?+

No. These tractors have no DPF and no EGR, and the SCR catalyst stays in place because it flows freely. If your tractor has very high hours, call us and we can check it with you.

Q3Do I need any extra hardware for the DEF delete?+

No. The DEF/SCR system is turned off entirely in the engine software. The Reflash Master handheld is the only tool you need.

Q4What should I do with the DEF tank?+

Once the tune is loaded, the engine no longer uses DEF. Empty the tank, rinse the system with washer fluid so nothing crystallizes, and leave it dry. The DEF warnings will not come back.

Q5Can I use the handheld on another machine?+

Yes, you keep the Reflash Master. Get in touch and we can license it for another tractor or machine on your operation.

Q6Will a horsepower tune burn more fuel?+

Usually not for the same job. The engine builds torque lower in the rpm range, so it works less hard under a normal load. Fuel use only goes up when you use the extra power on a bigger implement or a heavier pull.

Q7How fast do you ship?+

Most orders go out the next business day to anywhere in the US and Canada. Expedited orders placed after 12 ET ship the following day.
