2011–Present New Holland Sprayer DEF Delete Tune

A DEF fault on a Guardian always seems to land in the middle of a spray window. On FPT-powered sprayers, our Reflash Master handheld turns off the DEF/SCR system from the diagnostic port, and the exhaust stays as it is. Add a Stage 1 or Stage 2 tune at the same time for up to 20% more rated power. Earlier Guardians with a Cummins engine are tuned remotely instead. We ship all across the US and Canada.

Why delete the DEF on a New Holland sprayer?

DEF

Diesel exhaust fluid

Sprayers work in short, intense windows and then sit for weeks, which is hard on DEF. Fluid ages in the tank between passes, and by next season it can leave crystals in the pump, filter and dosing lines. On top of chemical, water and fuel, it is one more product your tender has to carry. Removing DEF from the software takes it off the list.

SCR

Selective catalytic reduction

The SCR system watches NOx sensors, line heaters and the doser all the time it runs. If one of them reads wrong, the engine drops power, and a slow sprayer in a narrow weather window means acres that never get covered. Once SCR monitoring comes out of the engine file, a tired sensor can no longer hold you back.

Two FPT engines in the current Guardian line

The newer SP310F, SP370F and SP410F Guardians run FPT engines, either the 6.7 L NEF or the 8.7 L Cursor 9. Every tune starts from a read of your own ECM, so the file fits the exact engine and rating in your sprayer.

02FPT Cursor 9 (8.7 L)Powers the larger Guardians. Stage 2 takes an SP410F to 480 rated hp.

Frequently asked questions

Q1How do I know if my sprayer has an FPT or a Cummins engine?+

Check the data plate on the engine and email us a clear photo. Current Guardians like the SP310F, SP370F and SP410F use FPT engines. Earlier models such as the SP.240F through SP.400F use a Cummins QSB 6.7 L or QSL 8.9 L.

Q2My sprayer has a Cummins engine. What do I order?+

Cummins-powered sprayers are not supported by the handheld. Order through our Cummins Engine Tunes page instead, and we tune the engine remotely over TeamViewer.

Q3Why choose Reimer Tuning for my New Holland sprayer?+

Every file is written by our own team from your sprayer’s ECM read. Files are returned in about 2 hours with a 1 year software warranty, and a tech is a phone call away during the flash.

Q4Do I need to change the exhaust?+

No. On FPT-powered Guardians the SCR catalyst stays on, and only the engine software changes.

Q5What do I do with the DEF tank?+

After the tune the engine stops using DEF. Drain the tank, flush the lines with washer fluid so nothing crystallizes, and leave it empty.

Q6Will a horsepower tune burn more fuel?+

For the same spraying, usually not. Torque comes in lower, so the engine works less hard under a normal load. Fuel only goes up when you put the added power to use on hills or in heavy, wet ground.

Q7How fast do you ship?+

FPT kits usually ship the next business day to the US and Canada. Expedited orders placed after 12 ET go out the following day.
