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.

Cummins Custom ECM Programming & Diesel Particulate Filter DPF Deletion Tuning for Cummins Paccar, Caterpillar, International & Maxxforce export/offroad diesel trucks. It is much easier to simply make small adjustments over time. The constants, the numbers programmed into the ECU, are used to try and get as close as possible to the 'perfect' fuel delivery, the O2 sensor is used for fine tuning those numbers. Here is what i would consider a minimalistic blue print for an ECU main processor.
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. Unfortunately 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 and 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.For further inquiries please contact us via email: [email protected] or call 02 8090 1881 (+612 8090 1881 internationally)If you are interested to send us your vehicles ECU for DPF OFF and performance tuning you will need also to download the 2x forms from this link below and send together WITH the ECU. See link below.
EGR DELETE / EGR BYPASSThe EGR valve (Exhaust Gas Recirculation) is an emission control device designed to reduce NOx emissions to help towards the ever more stringent Euro Emission Regulations. Celtic Tuning EGR Delete and EGR bypass software is designed to remove the functionality of the EGR valve to ensure it removes the running issues associated with these devices. Having your EGR Delete software can save you money in repairs and in fuel costs. Celtic Tuning are at the forefront of EGR Removal and EGR Bypass software and can correctly remove the functionality from the software of most ECU types.
Some companies will simply turn off the codes associated with it being unplugged but this is not the correct way. The EGR valve needs properly disabling to ensure it is not trying to recirculate exhausts gases whilst still physically working in the engine.IS EGR REMOVAL LEGAL?Please note that we only offer EGR solutions for Off-Road Usage only. Although it is not illegal to remove the EGR from your vehicle, it is an offence under the Road vehicles (Construction and Use) Regulations (Regulation 61a(3))1 to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet. Removal of the EGR will almost invariably contravene these requirements.The potential penalties for failing to comply with Regulation 61a are fines of up to £1,000 for a car or £2,500 for a light goods vehicle.
