Are you experiencing problems with your Isuzu Truck with DPF doing DPF Re-generations more frequently ?

Or is the DPF light now flashing but the truck won’t do a Regeneration?
Is the AdBlue causing issues?
All of these troubles can be an issue for your work truck off the road not earning money.

These errors, before long, will cause the engine to go into Derate-power (Limp) mode causing it an issue to drive and can lead to further problems.  This can be a sign leading to a failing DPF unit or AdBlue Module.  We have seen these symptom more and more on Isuzu “N” and “F”, GX and Giga series trucks.

Unfortunately the DPF unit on these trucks are not suited for low speed, urban type driving on the 3.0L & 5.2L 4HK1 & the 7.8L 6HK1, and 9.8L engines.

These engines are a magnificent, well designed and reliable engine and over the years we’ve seen these engines prove their effortless reliability.

Clearly, they are not designed around the emissions systems that are on them fitted to them, and the side effect is EGR, DPF and AdBlue problems that have been encountered by many owners of these trucks.

However, with a straight forward and reliable solution we have fixed this issue on the 3.0 right up to the large FX Range (FXY and FXM) and Giga 9.8L engines.  (NB This mod is technically for off road use only).

By only having the DPF removed out of the System the vehicle will detect the change and eventually cause the engine to go into Limp mode.  That’s where Chip Tuning come in.  We can remove the EGR System, the DPF unit and the AdBlue all together in a professional way that is nearly untraceable externally.  We also tend to keep the Catalytic Converter in place as that is the Primary source of emissions control.  This assists in keeping the toxic gases to a minimum.  The “Cat” also are not an issues for a Diesel engine.

As we Remap the Engine ECU  to Deactivate the EGR, DPF and AdBlue.  We have seen customers notice and report much better torque gains and better fuel economy as well.
This was even achieved on late model Isuzu fitted with either the Denso or Transtron ECUs.
On a 3.0 N Series you will pick up an extra 55NM of torque JUST WITH the DPF removed from the exhaust allowing the engine to breathe better.   On top of that we have a customized economy tune that will help the vehicle perform, making maximum efficiency out of a bigger size engine.  The Giga picked up 200NM of torque.

Each ECU has its own original file modified.  This preserves the factory key coding and vehicle/ECU matching.
