6.4 Regen Info

[bowtiehatr]

Diesel particulates in the exhaust are trapped by the DPF. Regeneration is the process by which exhaust temperatures are increased so the particulates are combusted. The frequency and length of regeneration will fluctuate as both are determined by the drive cycle. For most drive conditions, regeneration frequency will vary from 100 - 600 miles (161 - 804 Km) between occurrence and last from 10 to 40 minutes. The first regeneration does not require 100 miles (161 Km) and may occur at any time. The length of regeneration is usually reduced if a constant speed above 30 MPH (48 Km/h) is maintained.
The following is a list of normal operation while the vehicle is in regeneration, and do not require repair. If you are not sure if the vehicle is in regeneration,
IDS can be used to monitor the Diesel Particulate Filter (DPF) PID.

• Engine idle speed can be 1100 to 1200 RPM in park/neutral with foot off
brake.
• High idle speed drops to within 50 RPM of normal idle when the brake pedal is touched, PRNDL is actuated, or clutch is actuated.
• White smoke in cold ambients is normal and the mount will be increased
during regeneration.
• Powertrain power is limited to 325 horsepower(HP).
• Engine responsiveness may be slightly different than normal operation.
• During initiation of regeneration, exhaust smell may be noticed - especially
on new vehicles.
• Powertrain sound will be different including air induction noise (including
flutter on deceleration or engine shut down), exhaust noise, and
changes in engine radiated noise.
• During regeneration, exhaust temperatures are elevated.

i'm curious.. the 450's and 550's that are detuned to 325..i wonder what their hp numbers drop to while in regen.

I was at a drive thru with my foot on the brake when the truck jumped idle up to 1200, needless to say I was not paying attention, and almost smacked into the women in front of me. I put it in park and then tapped the brakes again, and the idle dropped. Took it to Ford and what else would they say... can't find a problem, bring it back if it does it agian.

same thing would happen to me with 20K on board sitting at red light. It felt like I was begging the truck not to run the light or over the car in front of me. I had to manually hold the trailer brakes down to keep it from taking off on its own, and Ford said " What problem, seems to drive ok to us, but bring it back in if it does it again" But with the KEM no more worries!!!be happy!!!

has the truck been programed to the lastest level

No, I do too much haulin for all that power, I have it in the prompts but it is in just tow mode for me., I have played with it when I first got it though, and WOW its awesome!!! but tow mode is still with no trailer = 4 smokin tires!
