okay how do you go about proving that it was the design ,etc that caused it and not the tuner that caused it to fail,
as far as the fuel I have always used a addative when ever I fill up
I talked to the service manger at the dealer and he was telling me it made no difference because of the tuner that would shoot it down I only have 78000 miles on my truck 2004
1) Ever noticed that injector failures happen to trucks that run tuners AND to trucks that have remained stock?
2) Injector failures have happened to trucks that run additives AND to trucks that run #2 straight.
3a) Injector failures happen to trucks with secondary filtration AND to trucks that only run the OEM filter.
3b) Failures happen to guys who change their filters religiously and those that have 30,000 miles on the same filter.
4) Ever noticed that LLYs and LBZs DO NOT have widespread injector issues like LB7s? The injector design was changed in the LLY, and the LBZ uses injectors very close in design to the LLY.
5) Ever noticed that injector failures seem to rise when the weather gets colder?
6) Ever noticed that injector failure rates rise just about the time a person posts that they're having issues with their batteries or some other electrical issue?
Place member "Oddplanes" has come up with some very interesting theories concerning the voltage that the injectors run on and how "clean" the power is. LB7s use 96volts, LLY 48volts, LBZ 24volts. The rate of failure drops off significantly as the firing voltage lowers in the later designs.
In the end, the only variables that consistantly point at the LB7 injector are the injector's design, its electronics and its supply voltage. If it were anything else, all the Dmax engine variants would have failures, let alone all the VW TDIs, Powerstrokes, and Cummins motors....
I could go on and on...but why? You're convinced that tuners are the only cause for injector failures.
