Additional Notes
Important Information regarding spark plug wires and spark plugs:
You must use noise suppression ignition wires AND resistor type spark plugs with this Controller.
The LNC-TRM controller contains High Frequency Digital Electronics and will NOT function
correctly without Noise Suppression Wires or resistor type spark plugs!
Nitrous, line-lock, trans-brake and other solenoid usage warning:
LPE has found that these solenoids can cause fly-back voltage levels at times in excess of 600 volts.
These voltage levels have the potential to damage sensitive electronics including the LNC-TRM,
the PCM/ECM and other modules in the vehicle. LPE has developed a transient voltage suppression
(TVS) diode kit (PN L450080000) for use with line-lock solenoids, trans-brake solenoids and other
aftermarket automotive solenoids of this type. The TVS diode is a special kind of diode used to
suppress voltage spikes.
Install the TVS diode across the solenoid
wires as close to the solenoid as possible.
Polarity does not matter (Red and Black
wires can go to either solenoid wire). If
there is no accessible ground terminal to
connect the diode to, as is the case with
many trans-brake solenoids, the diode should
be connected to the nearest ground source.
In the case of the diode for the trans-brake
solenoid, the diode should be connected to
the transmission case as it will provide a
ground path.
LPE recommends using TVS diodes on:
• Nitrous solenoids
• Nitrous purge solenoids
• Fuel solenoids
• Line-lock solenoids
• Trans-brake solenoids
