Kubota M6 DPF, EGR & DEF Delete Tune

Stop losing bale-wrapping days to regens and DEF warnings. Ship us your M6 ECM and ACM, and we bench flash both modules to switch off the EGR, DPF and DEF/SCR on the 3.8L and 6.1L engines. Stage 2 takes the M6-141 to 170 hp. We ship all across the US and Canada.

Why delete the DPF, EGR and DEF on a Kubota M6?

DPF

Diesel particulate filter

Soot keeps loading the M6 filter until the ECM forces a burn-off, dosing extra fuel and heat into the exhaust while you wait. Interrupted burns stack up, and eventually the filter has to come off for cleaning or replacement. Delete it and nothing restricts the exhaust.

EGR

Exhaust gas recirculation

Exhaust routed back into the M6 intake brings carbon with it, and over the seasons it crusts the EGR valve and cooler. Once the valve sticks the tractor throws codes and loses pull. Our file disables the EGR; the 3.8L gets a blocker plate with OEM gasket, and on the 6.1L the valve is simply unplugged.

DEF

Diesel exhaust fluid / SCR

The SCR side relies on fluid, a dosing module, line heaters and NOx sensors, and any one of them can derate the tractor with a full field still to wrap. The reflash turns the SCR off, so DEF is no longer part of your routine.

Kubota M6 for round baling

A round baler keeps the M6 at high PTO load for hours, which is exactly when the aftertreatment system acts up. What the tune changes:

PTO LOADFull chamber, no derateNo DEF or sensor faults cutting power while the bale is forming.
NET & WRAPKeep the cycle movingStop, wrap, kick out and go without a parked regen in between.
WET HAYPower for heavy cropStage 1 or Stage 2 keeps PTO speed up when the windrows are thick and damp.

Frequently asked questions

Q1My aftertreatment harness is damaged. Do I need to repair it?+

No. Our M6 file disables the full aftertreatment harness, and the CAN bus keeps working without it. You will not need resistors, and the sensors can stay unplugged.

Q2Should I hollow out the DPF or straight pipe it?+

Either is fine with the reflash. Hollowing leaves the factory canister in place. Our DPF/SCR straight pipe is made for the M6S only and is chosen in the options above; it is not sold separately.

Q3Does a Stage 1 or Stage 2 tune raise fuel use on an M6?+

We lift the fuel and boost maps evenly, so the M6 makes its working power earlier and runs at lighter load for the same job. Run it as usual and fuel use typically holds steady or drops, with the extra power on tap for a dense windrow or a full bale chamber.

Q4Do you ship to the United States and Canada?+

Yes. We flash M6 modules for owners in both countries. After checkout you get an email with shipping and customs instructions for the ECM and ACM.
