New Holland CR / CX Combine DEF Delete Tune

When the crop is ready, a DEF fault on a CR or CX can cost you the best hours of the day. The Reflash Master handheld turns off the DEF/SCR system on Tier 4B New Holland combines through the diagnostic port, and nothing on the exhaust has to change. Choose a Stage 1 or Stage 2 file for up to 20% more horsepower in heavy crop. We ship all across the US and Canada.

Why delete the DEF on a Tier 4B New Holland combine?

DEF

Diesel exhaust fluid

DEF is mostly water, so a CR or CX parked in a cold shed all winter risks a frozen tank or split lines by spring. In the heat of harvest, stored fluid breaks down and leftover DEF can dry into crystals inside the pump. Add the cost of keeping it on hand and the stops to fill it, and the system costs time when you have none to spare. Shutting it off removes all of it.

SCR

Selective catalytic reduction

Years of harvest hours wear down SCR parts. A tired NOx sensor, a plugged doser or a failed heater circuit can all set a fault and pull engine power with the hopper filling. Dealer parts and service calls in the middle of harvest are slow and costly. With SCR monitoring turned off in the file, those components can no longer derate the combine.

A custom file for every CR and CX

This kit covers Tier 4B CR twin-rotor and CX conventional combines. We start from your own ECM read, so every file is matched to the engine and rating in your machine, from the CR6.80 up to the CR10.90.

01CR twin rotorCR6.80 through CR10.90, including both CR9 models.
02CX conventionalThe CX7 and CX8 straw-walker models use the same handheld and steps.
03More capacity per hourExtra power lets you keep ground speed up when yields are high or straw is tough.

Frequently asked questions

Q1Why choose Reimer Tuning for my CR or CX?+

We build our New Holland combine files ourselves, and the techs who write them are the ones you reach on the phone. Your file is ready in about 2 hours with a 1 year software warranty.

Q2Is any exhaust work needed?+

None. Tier 4B CR and CX combines have no DPF or EGR, and the SCR catalyst stays on. The job is software only.

Q3What should I do with the DEF tank?+

After the reflash, the engine no longer uses DEF. Drain the tank and flush the system with washer fluid so leftover fluid cannot crystallize.

Q4Will the handheld work on another machine?+

Yes. The handheld is locked to your combine’s VIN, but it is yours to keep. Call us and we will reset it for the next machine you want to tune.

Q5Does a horsepower tune use more fuel?+

More horsepower means you can push the combine faster through the field without the engine lugging down. You may burn a bit more per hour, but you finish each field sooner, so the fuel used per acre tends to hold steady or come down.

Q6When will my kit ship?+

We ship most orders the next business day across the US and Canada. Expedited orders received after 12 PM ET ship the following day.
