Pretty Good Read On Injectors

Was doing some browsing and I thought I'd share. The last paragraph that talks about 6.0 injectors is pretty interesting. I wonder with FICM tuning you get this back?

PowerStroke

Early 6.0's had a function similar to the split shot injection of the 7.3's called pilot injection. Instead of being a hydro/mechanical action, however, on each compression stoke the FICM would energize the injector once to start combustion, turn the injector off, then energize it again. This was to provide less engine noise and improved emissions. But, this programming caused timing problems on hot restarts, resulting in rough running and loping, so the strategy was programmed out in later calibrations.

Ya this is very good. Thanks

There is a big part on sensors and volts. Are there any sensors that fail or should be replaced to keep a good system? And is there anything to do to keep proper volts or improve them?

They can turn that back on with SCT tuning. Most choose to leave it off
