VJ23 ECU
ECU for the VJ23 - fully programmable via USB or Handheld

Number of Points for each ignition map can be set from 4 to 20.
RPM of each ignition point can be set from 100rpm to 20000rpm in 100rpm steps.
deg...advance of each ignition point can be set from 0deg to 85deg in 0,1deg steps
increasing, or decreasing advance of all ignition points in same ignition map .. 3D Map...when checked enables programming of 3D interpolated map.
When unchecked the ignition curve is the same for all throttle positions.
Ignition Map Switch...enables, or disables ignition map switch.
When checked the ignition map can be selected with the switch.
Select Ignition Map...selection is active only when Ignition Map Switch is not checked.
Static Angle is pickup advance position from TDC (Top Dead Centre)
Advance...advances, or retards whole ignition map from -10deg to 10deg in 0,1deg steps. Positive value advances and negative value retards.
Advance Out 1...advances, or retards ignition advance on ignition channel 1, from -10deg to 10deg in 0,1deg steps. Positive value advances and negative value retards.
Advance Out 2...advances, or retards ignition advance on ignition channel 2, from -10deg to 10deg in 0,1deg steps. Positive value advances and negative value retards.

Delay Compensation...ensure correct ignition angle through whole revs. Default value is 30us.
.. TCT mode... Throttle Close spark Termination mode, reduces number of sparks
(spark is active every third revolution) above 8000rpm, when throttle is closed. TCT mode ensure better engine cooling.
.. Dynamic TPS...After fast throttle opening, ignition timing is advanced for short time. PV Parameters

Nr. of Points for each PV map can be set from 2 to 8.
RPM of each PV point can be set from 100rpm to 20000rpm in 100rpm steps.
%...PV position of each PV point can be set from 0% to 100% in 1% steps.
Power-up Test...enables, or disables PV test at switching on power supply.
Select PV Map... selection is active only when PV Map Switch is not checked.
Close Position of PV servo. Close position is 0% on PV map.
Open Position of PV servo. Open position is 100% on PV map.
Test Close...clicking on Test Close button, opens Test Close window. Function is active when PC-USB programmer and control unit are connected.
Test Open...clicking on Test Open button, opens Test Open window. Function is active when PC-USB programmer and control unit are connected.
Deviation...prevents 'hunting' of PV servo.


Misc Parameters

Pulses per Rev...set to 1
Rev limit...limits maximum revolutions. Set to maximum 20000rpm in 100rpm steps.
Shift light...activate shift light output above programmed revs. Set to maximum
20000rpm in 100rpm steps.
.. TPS closed (0%)... close position of throttle sensor
.. TPS opened (100%)... open position of throttle sensor
.. Smart Shift... when checked, kill time is automatically set dependent from revs and based on programmed Kill Time
Kill Time...for shifting without using clutch - shift sensor is required. Function is disabled with setting to 0ms.

Power Jet (Output Type)...when checked, solenoid output function is power jet
.. Duty Solenoid (Output Type)... when checked, solenoid output is duty solenoid
.. 'ON' rpm (Power Jet)... revs for activating power jet output
.. 'OFF' rpm (Power Jet)... revs for deactivating power jet output
.. 'ON' TPS (Power Jet)... throttle position for activating power jet output
.. 'OFF' TPS (Power Jet)... throttle position for deactivating power jet output

RPM of each duty solenoid operation point can be set from 100rpm to 20000rpm in 100rpm steps.

Supplied with 2 curves already programmed: 1 is slightly modified stock and 2nd may be suitable for unleaded race use.
