2011–2014 New Holland T9 Tractor DEF Delete Tune

An early T9 can spend more on DEF and SCR repairs in a season than many smaller tractors cost to run, and every failed sensor brings the job to a halt. Plug our Reflash Master handheld into the diagnostic port, and the engine file is rewritten to run without DEF while the exhaust stays as built. Add a Stage 1 or Stage 2 tune in the same visit for up to 30% more rated power. We ship all across the US and Canada.

Why delete the DEF on a Tier 4A T9?

DEF

Diesel exhaust fluid

Long days on a big cultivator or air cart mean a T9 drinks DEF almost as steadily as diesel, and keeping it topped up means hauling extra fluid to the field. DEF also has a limited shelf life, so fluid bought in spring can go off before fall work is done. Contaminated or aged DEF sets quality codes that reduce power. Once DEF is out of the file, the only tank you fill is the fuel tank.

SCR

Selective catalytic reduction

The first-generation SCR on these T9s uses a separate controller, a dosing pump, heated lines and NOx sensors, and all of them are now more than ten years old. When one of them drifts or fails, the ECM cuts torque, and on a 4WD that can stop a whole planting or tillage day. The reflash removes those checks from the engine file, so aging SCR parts can no longer cost you power.

Rated in software, built for more

From the T9.450 to the T9.670, the Tier 4A T9 shares one 12.9 L FPT Cursor engine. The gap between those models comes mostly from the factory calibration, and that leaves room a custom file can use without pushing the hardware past its design.

Frequently asked questions

Q1What makes a Reimer tune right for my T9?+

We build each Tier 4A T9 file in house from the read off your own ECM. It comes back in around 2 hours, includes a 1 year software warranty, and our techs will pick up the phone if you need help partway through.

Q2Will I have to change the exhaust?+

No. These T9s were built without a DPF or EGR, and the SCR catalyst does not restrict flow, so it stays on. If your tractor has very high hours, call us before you start.

Q3Is any extra hardware needed?+

No. The DEF/SCR system is switched off in the engine file itself, so the Reflash Master handheld is all you need.

Q4How do I handle the DEF tank afterward?+

The engine stops using DEF as soon as the new file is loaded. Drain what is left, flush the tank and lines with washer fluid, and leave them empty. DEF warnings stay off.

Q5Can I use the handheld on another machine?+

Yes. The Reflash Master is yours to keep. Call us and we can license it for your next tractor or machine.

Q6Does more horsepower mean more fuel?+

Not on the same job. The tune brings in torque lower in the rpm range, so the T9 is not working as hard to pull its usual load. You only burn more when you put the added power to work on wider or heavier tillage.

Q7How fast do you ship?+

Kits usually leave within 1 business day for the US and Canada. Expedited orders placed after 12 ET go out the next day.

Q8Disclaimer+

For off-road agricultural use only. Do not install on a machine registered for highway use. Check your state or provincial laws before you order.
