6.7.2.1 Timing Configuration
Maximum Timing – this is the max timing allowed by all the timing maps combined.
Coil time – 2ms
to 5ms. This is the maximum charge time that the user can select. The ECU will
vary the charge time automatically according to vacuum load from 2ms to the user selected value.
If the ECU heats up it is a result of too large charge times. 3.5 is a preferred starting value.
Rotary Trailing Degrees – set the trailing timing for rotary engines
Low / High Vacuum Timing Split – this sets the RPM split between the Low & High Vacuum
Timing maps.
6.7.2.2 Crank Angle Sensor
Gear Teeth – set the amount of teeth to align the crank sensor with ignition timing. Refer to the
installation section “Setting Crank Trigger Timing”
Timing sensor °BTDC – set the correction factor here to line timing up with timing light. Refer to
the installation section “Setting Distributor Timing and Setting Crank Trigger Timing”
6.7.2.3 Coil Combination
Coil combination – select the type of coil combinations you are using if not preset. On most
ECU’s this is determined by the firmware loaded into it and cannot be adjustable.
Two Stroke – this will select 2 or 4 stroke to correct injector % indication bar. It will be forced on or
off from the ECU. If it is on 4 stroke the injector time is calculated over 2 RPM’s while on 2 stroke
the injector time is calculated over 1 RPM. If you have an engine that does not rev high and the
injectors is too small you may put it on 2 stroke to double the injector time. Note however the
injector % during tuning not to go over 100% as this will occur at lower RPM.
6.7.2.4 Coil Driver Trigger Level
Coil Driver Trigger Level– this setting is very important and a mistake here can damage the ECU
or Coil. If you have a coil with no driver in the coil use Internal setting. If you use a TP100 or have
an internal driver in the coil use External setting with a pull-up resistor. To change this setting, click
on internal or external and type in YES. Then save the data to the ECU.
NB! This setting must be done before the ECU 10 way connector is connected.
