GPR (M150).July 2019 (1.11)

GPR (M150).February 2016 (1.07)

Current Version

• Update Anti Lag class: adds Anti Lag Fuel Margin
• Update Coolant Fan class: possibility for inverted output, uses maximum axis value for Coolant Temperature if Coolant Temperature is invalid.
• Coolant Pump: can be activated in after run conditions, or after run pump uses additional output
• Bugfix Nine Position Switch External: fallback to Default when CAN timeout
• Update LTC class: reports NAN in case of errors
• Update Launch class: Vehicle Speed dependency now on Engine Speed table axis
• Add 2x Driver Switch and 2x Driver CAN Switch
• Change Airbox Mass Flow to Hybrid Sensor.
• Update Ambient Pressure class: uses Airbox Pressure Sensor OR MAP Sensor for Estimate.
• Update Boost class: add second (inverted) actuator output and test mode, bugfix on Boost Aim State reporting
• Clutch State added
• Update Dual Throttle Servo class: report rest position if positions sensors are faulty, link Sensor Mode to Mode, change scheduling, bugfix Position report scheduling, 200Hz feedback filter.
• Update Wheel Speed class: considers Sample Teeth for determining 2 revolutions when Sensor Noise is reported
• Engine Crank Idle Mass Flow introduced, deleted Engine Crank Throttle Aim. Throttle Aim in cranking therefore now determined by Idle Mass Flow Feed Forward.
• Idle State = Enabled only when Engine State = Run
• Idle Ignition Timing initialised with cranking ignition timing when engines cranks
• Engine Crank Cycles: calculation corrected, increase cycle in full numbers when all cylinders are processed
• Engine Oil Pressure Warning: Enable, Activation and Reset Delay exposed
• Engine Load calculation can use Airbox Pressure
• Engine Speed Limit Fuel Margin: can be negative now, allows fuel cut first then ignition cut
• Engine Speed Limit Fuel Range parameter and channel introduced
• Engine Speed Limiting: only consider Anti Lag values if Anti Lag Mode is Enabled
• Engine Run Switch changed to type 'Indexed switch' with input from a selectable 'Driver' switch
• E8XX: CAN ID Base exposed
• Added Exhaust Lambda warning
• Added Exhaust Temperature warning
• Fuel Cut State now also reports cuts induced by engine speed limiting
• Injector differential pressure can use inlet manifold pressure sensor even when Inlet Manifold Pressure Mode is Estimated.
• Bugfix Fuel Closed Loop: clamp trim average also in shutdown
• Gear Lever Up Switch changed to type 'Indexed switch' with input from a selectable 'Driver' switch
• Gear Lever Down Switch changed to type 'Indexed switch' with input from a selectable 'Driver' switch
• Gear Shift: Allow Fuel Cut during shifts
• Gear Shift: Ramp out Engine Speed Limit during Recover
• Gear Shift Engine Speed Limit: use specific Fuel/Ignition Cut and Margin values
• Gear Shift: cut and retard table axis changed from Gear to Engine Speed + Engine Load Normalised, throttle aim table axis to Engine Speed
• Gear Shift: Power Off cases and Downshift Power On have additional Pre Shift and Post Shift states with fuel/ignition cut and retard, plus ignition retard in Recover State
• Bug Fix: downshifts can now be processed when Traction Control is active. New channel Engine Speed Limit Nominal.
• Gear Shift Request: check for Vehicle Speed greater zero and Wheel Speed source, debounce after shifts
• Gear Lever: use Lockout to get to Idle when going back to Sensor value after error healing
• Gear Shift/Engine Overrun/Idle: Disable Engine Overrun and Idle control when Gear Shift State is Pre Shift, Shift, Post Shift or Recover
• Gear Shift: Ignition Timing Normal is used at throttle blip
• Exhaust Lambda: only Bank 1 can fall back to Collector, not Bank 2
• Support of 2 injectors per cylinder ('high/low') with dual fuel film compensation and transport delay compensation
• Fuel Film Compensation activation: dependency from Engine Post Start Fuel Volume Compensation deleted
• Update Fuel Pump class: pump gets switched off when Hold is zero
• Fuel Pressure Warning: Enable, Activation and Reset Delay exposed
• Gear becomes Default if no source for Gear and Vehicle Speed is available
• Bugfix Ignition Timing Mode = Check Timing: Check now has priority over all other Ignition Timings
• Vehicle Speed Estimate logic slightly changed, renamed Throttle parameters
• Gear Input Shaft Speed becomes NAN if Gear Output Shaft Speed is NAN
• Idle Ignition Timing Limit Advance Target: changed to table, dependent from Coolant Temperature
• Idle activation only below a defined engine speed
• Inlet Manifold Pressure: introduce Correction for faster reaction
• Inlet Manifold Pressure Estimate: Mode introduced to select between ambient pressure reference, boost pressure reference or 100kPa reference, Filter introduced to filter estimated value
• Intercooler Temperature: now has Inlet Manifold Temperature fallback
• Ignition Timing Trim: Engine Load Average, Race Time, Auxiliary Output 1, Auxiliary Time ignition compensations/trims all are now trims, calculated into Ignition Timing Trim instead of Ignition Timing Compensation
• Ignition Mode introduced to allow for selective ignition disabling of cylinders/banks
• Ignition Output: Cut pattern can be selected
• Ignition Outputs now have voltage measurement for pins
• Ignition Cut State now also reports cuts induced by engine speed limiting
• Knock: highest knock level of all selected frequencies is used to adjust ignition timing
• Race Time: Activation and Reset work only if at least one condition is active
• Throttle Pedal: set to 0 if sensor is faulty
• Throttle Position: introduce dedicated sensor, set to 0 if sensor is not configured/faulty and Throttle Servo is also not configured
• Throttle static test parameter added
• Traction Engine Speed Limit Fuel Range introduced
• Traction Aim Compensation: additional gear compensation introduced
• Vehicle Speed Limit Engine Speed Limit Fuel Range introduced
• Wheel Speed CAN Scale: unit changed
• Warning: changed order of preferences, report system debug without delay of 1 event, hold Warning Source together with Warning Light
• MAP estimate calibration method uses Mode and Airbox Pressure and Ambient Pressure fall back, equal to MAP Estimate calculation.
• Documentation updates.
