New software version of the COMMANDER44 ECU




Improvement of sequential gearbox management:
• Optimization of the gear upshift time (faster upshifting).
• Ignition cutoff at gear downshift (faster downshifting on strong brakings of the vehicle).
• Possibility to select the old way of shifting on slower or less precise gearboxes.
• The ECU agrees to intervene on the engine even if the gear position measurement is in error.
Read carefully new documentation for sequential gearboxes.

 Improvement of the fly by wires security:
• Stop of the fly by wire electric motor (the throttle closes) when the position measurement potentiometer is in error.
This avoids that the ECU forces on the electric motor, which can cause damages.

(Improvements are added from a version to the next one)

Throttle/RPM : V440 (System V530)
Pressure/RPM : V440 (System V530)

1) Improvement of sequential gearbox management:
– A programmable ignition cutoff was already allowed on gear upshift.
– A programmable ignition cutoff has been added on gear downshift, facilitating the gears shifting during difficult conditions.
2) Auxiliary CAN-Bus management:
– Addition of two functions of simplified frames transmission toward the Sybele compatible dashboards.
  These functions allow a better confidenciality of the ECU tuning.

Throttle/RPM : V430 (System V530)
Pressure/RPM : V430 (System V530)

1) Securization of the wheels speed measurement:
– In the previous versions, when the wheels speeds were slow, a speed measurement error could happen which was causing a brief dysfunction of the anti skating.
– This version prevents from the speed measurement error.
2) Securization of the engine synchronization with a camshaft target with one supplementary tooth:
– In the previous versions, When the phase sensor was reading a camshaft target with one supplementary tooth, the engine synchronization could fail with an engine start not done.
  A second try of engine start was then necessary.
– This version ensures a perfect synchronization of the engine even in these conditions.
3)Improvement of the fuel high pressure control on direct injection engines
The new possibilities of tuning of the high pressure fuel pump in direct injection allow a very improved control of the fuel pressure.
4) Adding of a variable displaying the status of the engine synchronization
This variable gives in real time the engine synchronization and can be recorded with the Winjal scopes to visualize possible problems of synchronization lost causing engine misfires.

Throttle/RPM : V420 (System V520)
Pressure/RPM : V420 (System V520)

1) Significant improvement of the engine startup security:
– In the previous versions, during difficult conditions of engine start-up, the microprocessor could lose the capacity to perform its measurements (throttle, pressures, temperatures, …), causing an engine stalling.
– This version prevents the loss of the measurements even in case of battery tension drop down at the engine start.
2) Very efficient improvement of the launch procedure by a sliding of the launch limiter toward the race limiter:
To avoid the skating at the vehicle take-off, rather than going up suddenty from the launch to the race limiter, the rpm limiter is gradually raised from the launch limiter to the race limiter, at the maximum speed at which you allow the engine to rev up (tunable) – see new limiter documentation.

Throttle/RPM : V410 (System V510)
Pressure/RPM : V410 (System V510)

1) New calibration of the Auxiliary CAN-Bus for new Dashboards:
– A new “Extension” type allows to directly inform the new Dashboards type, like RgCartronic, Gems, Motec, …, and the data recordings devices. With this new type, almost all the measurements and calculation results of the ECU are automatically sent by the Auxiliary CAN-Bus in a simple way.
– This is in addition to the old “Injall” type which allows to directly inform the AIM type Dashboards.
2) Sequential gearbox
– Improvement of the calculation security of the ignition advance modification while gear upshifting: maps of advance modification are not used if “Ignition adavance modification” box is not checked. Whatever is their value, they do not change the ignition advance behavior.

Throttle/RPM : V400 (System V500)
Pressure/RPM : V400 (System V500)

1) Improvement of quality and robustness of the injection command:
– When engine speed instabilities of a sufficient level (due to vibrations or else) happened, the previous versions may lose one or more injections, up to making thinking to a small limiter.
– This new version never loses any injection (nor ignition) whichever is the engine operation.

Throttle/RPM : V370 (System V460)
Pressure/RPM : V370 (System V460)

1) Use of wide band Labda sensors:
– Improvement of the reliability of the injection time self learning at high richness.
– Better detection of Lambda sensor failure.
2) Sequential gearbox
– Automatic boost (autoblip) by the mean of the motorized throttle on gear downshift (needs an analogical powershift switch allowing to detect the downshifting, like strain gauge switches).
– Removal of interventions on injection time on gear upshift – quite never used – (only remains interventions on ignition, used by the whole of the motorists).
– Permission for the user to make the calibration of the gear position potentiometer and of the detection thresholds of the analogical powershift switch, even when the ECU has been locked by a professionnal license.

Throttle/RPM : V360 (System V450)
Pressure/RPM : V360 (System V450)

1) Direct injection:
Modification of injection pressure calculation for gasoline direct injection.
Gives a better adaptation of the injection times to the fuel pressure.
2) Richness correction:
Significant acceleration of richness correction recovery on re-synchronization on exit of rpm sensor signal loss.

Throttle/RPM : V350 (System V450)
Pressure/RPM : V350 (System V450)

1) Sequential gearbox:
More and more gearboxes are equipped with a strain gauge switch, and no more with a On-Off switch.
This version makes much more easier the tuning of this kind of switches.
The new version of the document “sequential gearbox” explains fully how to tune them with this new firmware.
2) RPM sensor signal loss:
Improvement of the resynchronization in case of rpm sensor signal lost.

Throttle/RPM : V340 (System V440)
Pressure/RPM : V340 (System V440)

1) Fuel pressure management:
Improvement of calculations for injection time correction in function of the fuel pressure (see documentation ‘Fuel pressure management’ chapter ‘Fuel pressure reference’).
– The fuel pressure reference, in case of specific calculations for injection time correction in function of the fuel pressure, is now given in pressure relative to atmospheric pressure and no more in absolute pressure.
– If you import the data from an old Tuneware with which the injection time was corrected by the low fuel pressure (not direct injection management), in this old Tuneware, the fuel pressure reference was given in absolute pressure. So you will have to correct the fuel low pressure reference in the new Tuneware.

Throttle/RPM : V330 (System V440)
Pressure/RPM : V330 (System V440)

1) Fly by wire:
– Allows adjusting the detection of a short circuit of the fly by wire.
– Allows the selection between synchronous command mode (standard mode) and asynchronous mode (advised new mode).
The asynchronous mode is preferably to use because
– it allow to manage a more precise position on very small openings, giving a better control of the tick over rpm,
– it consumes less current,
– it makes the electric motor runs cooler,
– it produces less spikes and less noise.
2) Electrical noise:
The interferences filtering on analog inputs have been improved, giving a better stability of the general operation.

Throttle/RPM : V320 (System V430)
Pressure/RPM : V320 (System V430)

1) Ignition:
– Allows the use of coil loading time extremely short (<500 microseconds) for very high efficiency coils or capacitive discharges
– Allows a better load of the coils at engine startup
2) Fly by wire:
– Allowed stop of the fly by wire command below a tuneable rpm, to avoid spikes at the engine start with inductive sensors and save power when the engine does not run
– Allowed stop of the fly by wire command if engine stalls, to avoid spikes with inductive sensors and and allow the automatic cutoff of the fuel pump

Throttle/RPM : V310 (System V420)
Pressure/RPM : V310 (System V420)

1) Injection:
– Self learning of the injection time base map (needs a professionnal license, or on option for standard licenses)
2) Fly by wire:
– Stop of the fly by wire command allowed below a tuneable rpm, to avoid spikes at the engine start with inductive sensors and save power when the engine does not run
3) Camshaft:
– The main camshaft (engine phase) can be the intake or the exhaust one as well
– Reading of camshafts targets with one missing tooth, one supplementary tooth and regular teeth

Throttle/RPM : V300 (System V400)
Pressure/RPM : V300 (System V400)

1) Camshafts:
– Management of proportional positioning of exhaust camshaft
– Reading of camshafts targets with one missing tooth and regular teeth
2) Injection:
– Up to 4 cylinders, management of not phased sequential injection allowed when phase sensor is missing – better than semi sequential injection. Allows to use cylinder by cylinder injection correction maps (see Engine configuration documentation)
– Up to 4 cylinders, semi-sequential injection commands one injector per cylinder, in place of one command for two cylinders previously (warning, the injectors wiring differs from previous versions of semi-sequential injection : it is now the same than the sequential injection one – see installation documentation)
3) Ignition:
– Up to 4 cylinders, management allowed of not phased static ignition when phase sensor is missing – better than twin spark ignition. Allows to use cylinder by cylinder advance correction maps (warning, the coils wiring differs from twin sparks ignition one: see installation documentation)

Throttle/RPM : V280 (System V360)
Pressure/RPM : V280 (System V360)

1) Better fault tolerance with CAN-bus sensors WinjNet (including Lambda controller DigiLSU)
– If you use a WinjNet sensor (connected to the ECU by CAN-bus), as for example the Lambda controller DigiLSU, it is mandatory to update your ECU.
– If you also use an injectors driver IMg06 (i.e. gasoline direct injection), this driver also being connected to the ECU by CAN-bus, it is also mandatory to update your driver with a CAN-bus error-tolerant software version (report to drivers dwonloads).
2) Full Display of calculation results of the auxiliary commands.

Throttle/RPM : V270 (System V350)
Pressure/RPM : V270 (System V350)

1) Auxiliary CAN-bus works with standard frames (11 bits identifiers) or extended frames (29 bits identifiers), with frame by frame selection.
2) Full display of PID calculations (Results, proportional, derived and integral).
3) Improvement of Lambda sensors fault detection.

Throttle/RPM : V260 (System V330)
Pressure/RPM : V260 (System V330)

1) Full management of turbos by turbo rpm or turbo pressure or both with dynamic selection of the management mode.
2) Dynamic management of fuel pressure with rail emptying at deceleration cutoff (see documentation ‘Fuel pressure’).
3) Advanced detection of speeds measurements errors.
4) Inverted management of on-off auxiliary outputs allowed.

Throttle/RPM : V240 (System V300)
Pressure/RPM : V240 (System V300)

1) Improvement of machine internal security and Tunewares security.
2) Improvement of the engine RPM measurement dynamic to get an even more precise following of the accelerations.
3) Modification of the tick over dynamic advance correction : this modification can induce a correction of the tuning of the tick over dynamic advance coefficient compared with the former versions.
– Modification of the average RPM at tick over.
– Adding of mini and maxi tunable limits of dynamic advance correction.
4) Adding of PWM software possibility on auxiliary outputs 4B et 5B.
5) Impovement of electrical spikes withstanding when using motorised throttles.

Throttle/RPM : V220 (System V250)
Pressure/RPM : V220 (System V250)

1) Added modification groups that allow to run in multi-maps without using advanced functionalities:
(Allows for example to get several engine tunings selected by a rotactor, but also allows many other applications).
Each modification group allows a specific engine tuning on ignition advance, injection time, richness target and turbo pressure target (if turbo exists).
Selection of the activation condition for each modification group.
See new documentation ‘Engine Tuning modification groups’.
2) Modification of the injection time correction by fuel pressure : the correction is done by a differential pressure calculation (see documentation ‘Fuel pressure’).

Throttle/RPM : V210 et V211 (System V250)
Pressure/RPM : V210 et 211 (System V250)

The throttle/RPM software has been modified to V211 version, as a small improvement has been done on injection phase calculation.
The vacuum/RPM software has been modified to V211 version, to fix a bug in the communications with Winjall.
This bug is only seen when using the atmospheric version (and not the turbo one) of the Commander44:
When Winjall is connected to the ECU and if you switch off and on the ECU, Winjall displays a reset request from the ECU, as if a major calibration had been executed, which is not the case.
This bug does not concern at all the engine working, but only the display of the reset request by Winjall.

For the remaining, the V211 version works the same than the V210 version:
1) Repetition of the CAN frames for slow dash boards. This kind of dashboard could not answer to the Commander which then stopped  to send dashboard informations
2) Impovement of the detection and display of the CAN bus errors.
3) Improved management of the sequential gear box.
4) Allows a fast and easy tune of the turbo pressure loop control.
5) Improved bang-bang management.
6) Allows getting the bang-bang from the tick over for canon ball move off.
