injector cycle time?
Hey yall my buddie's got a late 04 350 6.0 i stopped by for a beer and he had to move his truck real quick. While drinking my ice cold refreshing can of goodness he shut the beast down and i heard the injectors pulse for like an extra 15 seconds.
He said he brought the truck in for EGR issue and they also updated the pcm for the injector run time. Supposedly it extends the life of the injectors tremendously. I want nothin but the best for my super duty like all you guys and just curious the seriousness of this. I've checked TSB's, recall's, and haven't received and letters from my dealer indicating to bring her in. Just wonderin if any you guys know about this and any advice on addressing this issue. Thanks again boys

I had that flash on mine, but I took in back in for an EGR cooler replacement and they updated the PCM again. The newest flash doesn't buzz. If you search there is threads about what each flash does.

If you are having the issues and take the truck in under warranty, the tech will update your PCM with the inductive heating flash. The buzz flash is no longer being used by Ford.

With the inductive heating flash, the injectors are not purged of oil upon shutdown, but they use a technology to warm the oil in the injectors. The cold-start injector issues are known as "stiction". The 6.0L techs that are on this board say the inductive heating flash has been very good at resolving stiction.

is this "flash" something that can be done with the SCT, or will the SCT override it or something ??
