Then he cracked the intercooler (only found out about that at the 120,000km service) but I don't know if that had anything to do with the chip.įuel consumption never improved after the intercooler was replaced (for $1500 mind you!), and power didn't increase. When new the diesel everage 1100kms per tank, after 6 months of the dtronic chip is was down to 750km. He also noticed major fuel consumption increases.
With the chip it did pull harder earlier, about 1800rpm but didn't pull any harder and still died at 3500rpm. The original motor pulled hard from 2000-3500rpm with absolutely nothing above or below that. And to be honest it made two parts of fukall difference. My boss had one installed on his GU IV Patrol Manual 3.0TD about 4 years ago. They are in your sump and you need to halve your service intervals to get them out.
But most of these didn't come out the exhaust. The smoke is unburned hydrocarbons and particulates and are highly carcinogenic. If you re-chip the ECU and are marvelled at the extra power but a bit concerned about the extra smoke from the exhaust, be very concerned. Add to that the reduction gearing that these vehicles offer in 1st gear, low range and you have a prescription for disaster for transmissions, transfer cases, prop shafts, differentials and axles all working beyond their designed loads.Īnd a final word. This is because they share transmissions with their petrol equivalents that don't produce the huge lump of torque that diesels do. It is usual that the engine power of modern diesels is not fully tapped. In the Patrol 3.0lt, this engine suffers oil starvation to the top of the engine running at high revs. In the Jackaroo it may be critical to lubrication of the common rail fuel injection system which is already vulnerable to degraded or substandard oil quality. In Jackaroo and Patrol 3.0lt extreme duty (which includes getting the most out of the engine in traffic light drag races) may result in inadequate lubrication and result in engine failure.
Putting power chips in ECUs that control diesel engines is fraught with danger.
