25.3 ECU setup
First, go to Fuel Injection Setup and enter the following:
•
Max RPM: setup according to your engine;
•
Injection mode: setup according to your engine;
•
Idle by: TPS (fixed injection time on idle), MAP (injection time
by MAP readings);
•
Engine type: Rotary;
•
Max boost pressure: setup according to your engine;
•
Injectors banks: FT has two banks, setup how you want to use
them (both as primary or A as primary and B as secondary);
•
Acceleration fuel enrich: use by TPS, it’s more accurate;
•
Number of cylinders/rotors: setup according to your engine;
•
Fuel injectors deadtime: if you don’t have this info about your
injectors, use 1,00ms;
Now, go to Ignition Setup and select:
•
Ignition: Crank/Cam Ref. w/ Multi Coils;
•
Crank Trigger Pattern: select option “12 (at crank) 24 (at cam)”;
•
First Tooth Alignment: 5 tooth BTDC;
•
Crank Ref Sensor: Magnetic;
•
Crank Ref Edge: Falling edge;
•
Cam Sync Sensor: Magnetic;
•
Cam Sync Polarity: Falling edge;
•
Ignition Mode: Wasted Spark;
•
Ignition Output Edge: see table below;
•
Ignition Dwell: setup according to your coils, default is 3,60ms;
•
Ignition Output Voltage: 12V.

Notes:
1. Use two (2) ignition units
2. Considering that MW PRO-14/R trigger edge need to be configured as Falling Dwell leaving pins 9 to 10 unconnected. See page 9
of MW Ignition manual for more details
3. There is no set up the trigger edge of Pro-Drag 4/R. Trigger edge is Falling Dwell by default.
After setting up Fuel Injection Setup and Ignition Setup menus, make sure you go through chapter 11.3 to generate a fuel and timing base
map for your engine.
25.4 Ignition coils wiring
After setting everything up, the ignition outputs of the ECU are ready to be connected to your coils or ignition modules. FT ECU ignition outputs
cannot be connected directly to dumb coils, only to smart coils (coils with integrated ignition module) or ignition modules.
For 2 rotor engines, the gray wires are connected as the table below shows:
