John Deere 50G–85G Mini Excavator DPF & EGR Delete Tune

John Deere’s 50G, 60G, 75G and 85G minis spend much of the day trenching, grading and swinging at part throttle, then sit idling between truckloads. That light duty clogs a DPF quickly. Send us the Yanmar engine control module and we bench flash it with EGR and DPF turned off, then return it the next business day. We ship all across the US and Canada.

STEP 04ReinstallPlug the ECM back in, then gut or pipe the DPF.

After the tune

EXHAUSTHollow out or straight pipe the DPFWith regens disabled, empty the DPF canister or replace it with a straight section of pipe. These minis have no DEF tank or SCR catalyst, so the rest of the exhaust is left alone.
EGRShut off in the softwareThe file holds the EGR valve shut at all times, so exhaust stops cycling back into the intake. No parts need to come off the engine.

Why delete the DPF and EGR on a John Deere mini excavator?

DPF

Diesel particulate filter

A mini excavator digs in short bursts, then idles while the truck is loaded or the crew sets pipe. The small Yanmar seldom builds enough exhaust heat to burn soot passively, so the machine keeps asking for parked regens that stop work on site. A replacement filter is a big bill for a machine this size. Gutting or straight piping the DPF puts an end to regens.

EGR

Exhaust gas recirculation

The Yanmar EGR system feeds a share of exhaust back into the intake to cut NOx. Hours of idling and light digging coat the valve and intake with sticky carbon, and once the valve sticks you get hard starts, black smoke and a machine that won’t pull a full bucket through clay. Our file switches the EGR off inside the ECM, so the engine breathes clean air.

Frequently asked questions

Q1Which part do I send in?+

Just the Yanmar engine ECM. That one module controls the EGR and DPF on these minis, so nothing else needs to come off the machine.

Q2How long will my excavator be down?+

We program the ECM and ship it back the next business day after it reaches us, so the downtime is mostly transit in each direction.

Q3What happens to the DPF after the flash?+

Once the ECM is back in, empty the canister or fit a straight pipe. These minis carry no DEF or SCR, so the DPF is the only exhaust part to deal with.

Q4Can the dealer wipe the tune?+

Yes. A dealer reflash or software update may replace our file, so let us know before the machine goes in for service and we can help you plan around it.
