Example: RPM for a shift light, RPM or TPS to switch nitrous on, water temp to control a fan relay.
Also set the appropriate values in the min and max blocks e.g. shift light – min 5000 max 8000.
The light will switch on at 5100 RPM’s and switch off at 8100 RPM’s. If the min value is smaller
than the max value, the relay will switch on between the limits. If the minimum value is higher than
the max value, the relay will switch off between the limits. Note also that the relay will switch on at
the value + 1 increment and off at the value – 1 increment. Thus for example if you select RPM
and set 4000 and 5500, it means that the relay will switch on at 4100 and 5400 and off at 3900
and 5600 rpm’s.
Note that on GP 1 the water temp works different from all the other logics. The output will go on
when Max + 1 is reached and go off when Min – 1 is reached. This is to allow the tuner to set a
dead band value for the fan to start and stop. This will prevent the fan from start and stopping too
much.
Note! The idle control also uses these outputs. For idle control the setting must be set to Idle
Control and then the parameters will be set on the Idle Control field. The Min and Max values does
not affect the idle control operation. They are not used.
Note! The Micro Fueling can also use these outputs and the take priority. If it is activated there the
selection will be off and the values ignored. The Min and Max values does not affect the Micro
Fueling operation. They are not used.
Note! Only on the Lexus program GP 2 can be used for RPM calibration for different rev counters.
This is due to the fact that the gearbox and idle control use the normal RPM output. Set it to RPM
and then set the Pulses / RPM for the required rev counter.
The following values need to be set for the different conditions:
RPM – RPM/min 100rpm increments
Lambda – voltage 0.01volt increments
Vacuum – pressure 10 Kpa increments
Water temp – degrees at 1°C increments
TPS – percentage at 1% increments
Air temp – Degrees at 1°C increments
Idle Control – if idle control is used
This block is for Rev counter calibration. You can adjust the number of pulses per revolution which
is handy for engine conversions.
