FTSPARK
2. Presentation
FTSPARK is a high energy capacitive ignition module that meets the highest
levels of spark energy demand, being able to generate a spark with 750mJ
(mJ = mili Joules guaranteed minimum energy, can reach up to 850mJ) or
1500mJ (FTSPARK EXTREME - guaranteed minimum energy, can reach up
to 1700mJ) and it is capable of discharging with currents up to 140Amps and
475V in the primary coil circuit. With these features, the FTSPARK generates
a spark with approximately 5 times more energy and 10 times more current
compared to a SparkPRO, ensuring a complete combustion in any condition,
especially in extremely rich air fuel ratios.
FTSPARK Differentials:
- Compatible with rotary engines
- Programmable energy level over CAN bus or analog input for energy
level conguration
- 475V in the primary coil circuit, helps avoiding electromagnetic noise in
the system
- Up to 140Amps in the primary coil circuit using FuelTech CDI Racing
Ignition Coil
- Up to 175Amps in the primary coil circuit using FuelTech CDI Racing
Ignition Coil and FTSPARK 1500mJ (FTSPARK EXTREME)
- CAN communication with FuelTech Power FT product line, for diagnostics
and data logging
- Anodized aluminum housing
- Automotive connector with gold-plated terminals
- Serial bus (1 wire) allows the use of only one ECU output to trigger all
FTSPARK ignition outputs
3. Warranty terms
The use of this equipment implies in total accordance with the terms described
in this manual and exempts the manufacturer from any responsibility regarding
product misuse.
This product must be installed and tuned by specialized auto shops
or professionals with experience on engine tuning.
The oversight of any of the warnings or precautions described in this manual
can cause engine damage and lead to warranty void of this product warranty.
Before starting any electrical installation, disconnect the battery.
This product is not certied for aeronautic purposes or any ying vehicles, as

- Voltage supply required for full power: 14-26V. Minimum voltage during
cranking 8V;
- Maximum operating frequency: 670 Hz;
In some countries where an annual inspection of vehicles is enforced, no
modication in the OEM ECU is permitted. Be informed about local laws and
regulations prior to the product installation.
Important warning for proper installation of this product:
Always remove and insulate unused wires. NEVER roll up excess
wiring as this may create an antenna that captures electromagnetic
interference that may generate product malfunction.
Limited Warranty
This product warranty is limited to one year from the purchase date, only
covering manufacturing defects and requiring purchase invoice presentation.
Damages caused by misuse of the unit are not covered by the warranty.
Warranty void analysis is done exclusively by FuelTech technical support team.
WARNING:
Warranty seal violation results in product warranty void.

5.1 Mounting
Mounting must be done using the rubber cushions. Always use the 4 spots
available on the FTSPARK body.
The FTSPARK must be installed as far away from heating sources as possible
(such as turbochargers and exhaust manifolds) because it generates a lot of
heat by itself.
If installed on the engine bay, it must be mounted where air ows best.
5.2 Power supply
Never Invert the FTSPARK power connections.
The FTSPARK power supply, as well as all other electric loads of the car, must
pass through the master switch for safety reasons and the master switch must
NEVER interrupt the battery ground, always the hot terminal.
IMPORTANT
- Always connect the power supply harness directly to the battery
with a 50A fuse for each FTSPARK BOX.
- Do not use the chassis or engine block to ground the FTSPARK.
Use the negative battery terminal.
To turn the FTSPARK on and off use a 12V switch connected to the analog
input on pin 12.
Do not connect the FTSPARK to a voltage booster, it demands current peaks
of more than 100A and will cause the system to malfunction. Do not use the
The FTSPARK on systems with over 20V power supply.
Do not use FTSPARK on systems with power supply voltage over 26V.
5. Installation
Capacitive ignition systems require special installation care for correct operation.
The vehicle’s electrical system suffers high current and voltage demand from
the FTSPARK ignition system. It is essential to follow the installation instructions
in this manual.
NOTE
If the LOG shows energy drop, it’s necessary to check the harness and
wires that go to the battery. And on situations where the FTSPARK is far
from the battery, it’s mandatory to increase wire gauge.
A good solution is to make a secondary power terminal from the battery,
using 2 AWG cable.
