Long story, i'll make it short. I just bought this truck 4 months ago, I installed a new to me motor that turned out to be built and running 11:1 compression. The truck has 172k miles on it, and a lot of deferred maintenance ("new" motor has 60k miles). I'm working through the bugs, so there are a lot of unknowns.
It has New Ford front O2 sensors, so i'm confident my readings are accurate.
It has a custom tune from a company up in Michigan, i purchased it for my SCT to get the truck on the road. The tuning is just not there, so i purchased HP Tuners so I can do my own work. That being said, I think i have a mechanical issue with the truck yet.
The guy who tuned the truck is well known for tuning these things with mods, I just can't imagine his tuning would be this far off (biggest mods are increase CR, headers, and Cold air intake using the stock MAF and a housing that should be very close to stock size).
Anyway, as i was digging through the data, it appears the values HP Scanner is providing for Injector Pulse Width is extremely low. Can someone take a look at the below log file:
- I don't think the Pulse width is correct, maybe off by a factor of 10
- Maybe you guys see something that stands out for why my LTFT's are so high. I have a fuel pump on order thinking my pump may not be keeping up . . . but when i calculate the Injector Duty Cycle with these numbers it is super low.
Thanks so much for the help!
