5.3 Ignition settings 5 SETTING UP A BASIC CONFIGURATION
5.3.19 Suzuki Vitara 2.0
This mode is considered experimental. It works for a later modification of Suzuki’s irregularly spaced teeth that
has 11 teeth instead of 12. Supports sequential injection. Because of the nature of the VR sensor, it can trigger off
either edge, depending on the wiring. Ignition input capture should be tried both ways and set to which one gives
you the most stable signal.
5.3.20 Daihatsu 3cyl
This mode is considered experimental. The Daihatsu three cylinder version has 3 equally spaced teeth in a
distributor with a fourth tooth adjacent to one of the teeth and a VR sensor. Supports sequential injection.
5.3.21 Daihatsu 4cyl
This mode is considered experimental. The Daihatsu four cylinder version has 4 equally spaced teeth in a distrib-
utor with a fifth tooth adjacent to one of the teeth and a VR sensor. Supports sequential injection.
5.3.22 VTR1000
This ignition appears on some Honda V-twin motorcycles. It uses a 12-3 crank trigger with a VR sensor and no
cam sensor. Sequential injection is not supported.
5.3.23 Rover #1
This mode is used on Rover K-series engines with a crank trigger wheel with 36 base teeth and two one tooth
gaps, 180 degrees apart. This only allows a single coil and batch fire injection. Cam input is not supported.
5.3.24 Rover #2
This mode is used on Rover K-series engines with a crank trigger wheel with 36 base teeth and four one tooth
gaps. This only allows a single coil or wasted spark ignition and batch fire or semi-sequential injection. Cam input
is not supported.
5.3.25 Rover #3
Similar to Rover #2, but the gaps are two teeth wide and positioned differently. As with Rover #2, supports wasted
spark and semi-sequential injection, but does not support cam input.
5.3.26 GM 7X
This appears on several GM four and six cylinder engines with distributorless ignitions. GM refers to the crank
wheel in their internal documentation as a 7X trigger wheel. It has six equally spaced teeth and a seventh tooth for
cylinder identification. Cam input is supported for sequential injection.
5.3.27 QR25DE
Used on the Nissan QR25DE and some other Nissan four cylinders with crank triggering. The crank wheel has 36
base teeth with two gaps two teeth wide. Supports fully sequential injection.
5.3.28 Honda RC51
