Had mine done today. Fuel economy did seem better on the way home. Was averaging 11.8 city traffic, but got 9.8 on the 20km drive home, which included some full throttle traffic light take offs.

Pre new DPF ave 11.5 and climbing. New DPF first tank 10.32l/100km and looking to be just under 10 for second currently sitting on 9.9l/100km. I have seen low 5's while cruising at 70km/h. Cruising freeway at 100km/h uses 7.6l/100km at the moment.2018 150 Series Crystal Pearl Prado VX 2.8l. 2 inch King springs and Bilstein shocks, Airtek TJM snorkel.

Just had the 1 year /20000km service [ at 10000km!]. I specifically asked them to do the DPF update and it was done. According to the service bloke, issues with the DPF revolve around the front of the DPF. Apparently it was not getting sprayed enough diesel to burn off the crud. The update changes the spray pattern to make sure that the front does get sprayed properly. He also said the problems were showing up in those towing long distances so the build up of crud didn't get cleared. The explanation makes sense. Time will tell.

I'm guessing they were referring to the volume the injector sprays out, cant see how software would alter the shape of the injector nozzle to change the spray patten.
I've had the update too now and going by my ODO I'm due for a burn in the coming days so looking forward to seeing if there is any difference to the burn duration.Cheers

Hey there,
I'm getting a little confused. Does the ECU upgrade have an effect on fuel economy or is that just the DPF replacement. It looks like everybody is talking about 2 different issues, or maybe they are related, I don't know anymore!!!!!!!! We have a 2016 Kakadu and we don't generally get too much better than 10L/100km on a trip, generally 10.4 and 12-14 around town.
Thanks for your help
Paul

I took a photo somewhere at half way 800km down and DTE said 800km to go. Started at about 1400 from memory.
