Dfco Enable Clutch Transition. DFCO Enable Max Load: Above this Load value, DFCO will be disabled.
DFCO Enable Max Load: Above this Load value, DFCO will be disabled. This reverses the transfer of torque. The Temp parameter says that the temp must be above XXX to enable the clutch transition mode and its set to 284. The In the DFCO tab on the left side about 3/4 of the way down is an option to disable fuel cutoff will this choice also mean that I lose fuel cutoff ability of the ECM program at the DFCO (Deceleration Fuel Cut Off) Tables While tuning, you want to disable DFCO so your scanner does not pick up skewed data. A control system for enabling an engine to operate in a deceleration fuel cutoff (DFCO) mode is provided. At those speeds, I don't like to allow engine overrun as it tends to get jerky below that point. Also in DFCO, what is "Enable Clutch Transition"? Is it something with the TCC? If so, mine looks to be turned off. How do I reset and disable trims in the VCM? The guys having trouble with poping when dfco is enabled what is your spark advance set to while in dcfo mode? Stock on my car was 10 dec ATDC as soon as i changed it The problem with DFCO and popping is the time frame where it's running pig rich during overrun, then DFCO finally engages and the lean transition creates an AFR in the I see where I can set DFCO to 284*, but I also see DFCO Enable Clutch Transition set to 104*. What does that do? Seems like it means when I push in the clutch, it will Yea, it's not enabled by default in the vettes but it is the only thing that has solved my decel surging. now the PCM cuts fuel on clutch transitions and whenever you decelerate. So you have to be in your gear and let off the gas (without clutch) for DFCO to activate. . The DFCO MAP settings are well below my idle readings. " This is set to 322kmh stock, which means DFCO M6 will never be In order to enter the DFCO mode, it is desirable for the torque converter clutch to be applied. This is used for re-entering DFCO. I'll have to look at my logs I see where I can set DFCO to 284*, but I also see DFCO Enable Clutch Transition set to 104*. I'll try this when I take lunch today. I had it disabled from the I found that DFCO doesn't work during clutch transitions (aka: shifting through the gears). I'm playing Decel Fuel Cut (DFCO)So why bother? Easy. For clarity, on decel with clutch in there is no pops and bangs which leads me to believe if CFCO is enabled and a good thing, therefore I want DFCO enabled? If I want DFCO The wackiest one is the "DFCO Enable Clutch Transition" as all the parameters under that section definately won't be met during normal driving. The only problem was that it caused the engine to stall when the clutch was LSxpwrdZ, I appreciate the look-see. I've gotten into the habit of pushing the clutch in and with this new-found DFCO There is B3312 DFCO M6 Speed, which has the description, "Vehicle speed must be above this to allow DFCO M6 to occur. DFCO Torque Ramp On Rate: DFCO Torque LSxpwrdZ, I appreciate the look-see. I think the DFCO enable clutch transition may be the culprit; I 'll let you know how it goes. A big Thanks to Ed Mowton, from whom I purchaced my HPT Pro, DFCO Closed Throttle Delay Extended: This is the delay after DFCO conditions are satisfied that injectors will be disabled. (DFCO is considered active and Fuel is These values over ride ANY of the DFCO Enable Normal Section qualifications (Enable, Entering, Exit) if recent clutch activity has been detected. More specifically, the applied clutch allows torque to be Disable P0068 by jacking up the Enable RPM to a high number, I used 8000. The system includes: an enable module that selectively enables a DFCO mode I have the DFCO Enable ECT set to 284 and the Clutch transition set to 284, I do have an option to disable STFT. This translates to much more effective engine I took a look into my HPTuners suite last night and these parameters take into consideration transmission (manual clutch It doesnt seem like it is enabled on the F bodies either. Also return the DFCO Enable Clutch Transition tables to stock as I never But, for those of you doing your own tuning (LSx), you'll need to send a clutch switch signal to the PCM if you want DFCO to function out of the box. What does that do? Seems like it means when I push in the clutch, it will DFCO is an acronym for "deceleration fuel cut off" It's programming in the engine computer that allows the fuel injectors to turn off anytime the car has enough momentum to I found that DFCO doesn't work during clutch transitions (aka: shifting through the gears). These values will remain As with an open switch, the PCM thinks that the clutch pedal is pressed, thus the DFCO won't enable. DFCO Entry: Enable tests passed, VCM selects spark threshold/ ramp down values and Enable Qualification hysteresis values while getting to fuel cut. DFCO Enable N/V: Above this N/V value, DFCO will be disabled.
