Just looking around finding out things about my F250 Powerstoke diesel
was just in the shop for 2 days for a 4 hour job...... one of the recalls was to reflash the ecu..... because it had a virus??? at least that what the service manager told me... QUOTE The Power Stroke Diesel is designed to last for 250,000 miles, more than twice the life expectancy of comparable gas engines. That translates to great resale value for Ford F-Series Super Duty owners. so they only expect the gas engine to last 100,000 miles I sol dmy mountaineer with 190,000 on the clock and it pulled strong and burned no oil... marketing.......... go figure.. |

'bug' i could believe. reflashing ECU maps happens all the time, for a vaariety of reasons. sometimes early cars develop driveability or economy issues in parts of the operating envelope that the factory engineers and tuners can correct. sometimes (this is pretty prevalent in the VW-Audi turbo circles) the service department will reflash a 'chipped' ECU that comes in with problems - they take out the 'unknown' stuff and replace it with 'factory' parts they're prepared to deal with. i don't think the mere presence of a "performance tuner" ship program will void a VW-Audi warranty, but there is the presumption that it was done to achieve higher boost levels and that -will- void the warranty... ECU mapping is part engineering, part black art. it's unsurprising minor changes occur from time to time. |
