12 Ignition
FT500 has 8 ignition outputs that can be used according to the needs of the project, controlling a distributor or
a crank trigger.
12.1 Ignition with distributor
When using this ECU with a distributor, the only active ignition output is gray #1. This wire must trigger an
ignition module or a coil with integrated igniter.
Coil with integrated igniter (smart coil)
These are coils with at least 3 input wires and a single spark plug wire output. With coils like that, set the
For Honda distributors
Selecting the wrong option will damage the coil and the ECU in a few seconds.
FuelTech SparkPRO and dumb coil
FuelTech SparkPRO is a high energy inductive ignition module that can be used with any kind of coil with no
integrated igniter.
Notice also that this module must be placed the closest possible to the ignition coil.
Warning about the SparkPRO-1: An excessive charging time (Dwell) can damage the SparkPRO and the coil. It is
recommended to use a Dwell map with 6ms at 8V, 4ms at 10V, 3.60ms at 12V and 3.00ms at 15V and check coils
temperature at the beginning.
Capacitive discharge ignition module (MSD 6A, MSD 7AL, Crane, Mallory)
, usually, the white wire, but, for MSD,
the yellow wire is automatically set up as MSD output.
The installation of ignition modules must always follow what is indicated by its manufacturer in the instructions
manual. This ignition module will receive a Points signal from FuelTech. Ignition coil must follow the ignition module
manufacturer recommendations as well.
Important notes:
- The module must be placed the closest possible to the ignition coil, and never inside the car, in order to avoid
the risk of interference on electronic devices.
- The length of the wires that connect the ignition module to the ignition coil must be the shortest possible.
- ,
- It is not possible to control the ignition Dwell when using this type of module.
MSD Legacy input
When using MSD ignition modules with a distributor, it is necessary to connect a FuelTech white wire to the MSD
Legacy input. That makes FT ECU to perform a faster timing control, especially needed when using Drag Race Features.
