RPM Limiters

• RPM Limit Cutoff: Above this RPM, injector fuel cut will occur.
• RPM Limit Launch RPM: Above this RPM, injector fuel cut will occur.
• RPM Limit Oil Overtemp RPM Max: Below this RPM, Oil Overtemp RPM Limiting will be allowed.
• RPM Limit Neutral: RPM Limit when in neutral.
• RPM Limit Neutral Cutoff: Above this RPM, injector fuel cut will occur for manual transmissions in neutral.
• RPM Limit Neutral Cutoff Auto: Above this RPM, injector fuel cut will occur for auto transmissions in neutral.
• RPM Limit Neutral Exit Speed: Below this speed for manual transmissions the neutral RPM limit will be used.
• RPM Limit Neutral Min Load: Neutral will not be used if below this load.
• RPM Limit Neutral Max Load: Neutral will not be used if above this load.
• RPM Limit Drive: RPM Limit when in drive.
• RPM Limit ETC: Above this RPM the RPM will be limited using the electronic throttle control(ETC).
• RPM Limit ETC Hyst: RPM must drop by this amount to disable ETC RPM limit.
• RPM Limit ETC Integral Initial: The initial value of the RPM Limit integral term.
• RPM Limit ETC Integral Max: The maximum value of the RPM Limit integral term.
• RPM Limit ETC Integral Min: The minimum value of the RPM Limit integral term.
• RPM Limit ETC Integral Gain: The integral gain for the RPM Limit.
• RPM Limit ETC Proportional Gain: The proportional gain for the RPM Limit.
• RPM Limit vs. Output shaft RPM: RPM Limit in relation to output shaft RPM.

Deceleration Fuel Cutoff (DFCO)

• DFCO Enable RPM: Above this RPM, DFCO can be enabled.
• DFCO Disable RPM: Below this RPM, DFCO will be disabled.
• DFCO Enable Speed: Above this vehicle speed, DFCO can be enabled.
• DFCO Disable Speed: Below this vehicle speed, DFCO will be disabled.
• DFCO Enable Max Load: Above this Load value, DFCO will be disabled.
• DFCO Enable N/V: Above this N/V value, DFCO will be disabled.
• DFCO Torque Ramp On Rate:
• DFCO Torque Ramp Off Rate:
• DFCO Closed Throttle Delay: This is the delay after DFCO conditions are satisfied that injectors will be disabled.
• DFCO Closed Throttle Delay Extended: This is the delay after DFCO conditions are satisfied that injectors will be disabled. This is used for re-entering DFCO.
