FTSPARK
NOTES
- This serial protocol is not compatible with any other ECU, it’s a FuelTech
exclusive compatibility.
- The serial bus triggering can
NOT
be used for rotary engines.
6.3 Input signal trigger edge
All the FTSPARK units are designed to receive FALLING TRIGGER EDGE signal
from the EFI, make sure you have your EFI settings for ignition output signal
as falling edge to assure accurate ignition timing.
6.4 CAN network
The CAN network allows the ECU to select the energy level without the use
of the energy level selection wire.
In addition, FTSPARK is capable of generating a series of CAN network
diagnostics that are recorded by the ECU (FuelTech FT500 or higher).
CAN Network connection
FTSPARK harness has 2 connectors for CAN network connection with
FuelTech products.
1 - Female connector
2 - Male connector
3 - CAN terminator
Plug the male connector from the FTSPARK harness (2) to the female connector
on the back of the ECU. In case you have other products that are already
connected to the CAN network (WB-O2 Nano, for instance), then connect
the male connector from FTSPARK to the female connector from the WB-O2
Nano. It may be necessary to remove the CAN terminator from the WB-O2
Nano harness.
The CAN terminator (3) must remain plugged to the female connector of the last
equipment on the network. This helps to prevent noise on the CAN network.
Male connector from the FTSPARK (1) MUST NOT be plugged to the female
connector on the same harness. CAN communication will work properly with
this connection.
FTSPARK EXTREME
For 8 Cylinder engines using 1500mJ (minimum energy, can reach up to
1700mJ) it’s mandatory to have the Serial bus activation wire shared between
Box A and Box B, connecting it to pin 24 in both boxes.
