Lingenfelter L460145297 Lingenfelter LNC-2001 LS Timing Retard Launch Controller LSA LS9 v1.7 - Manual (Page 11)

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-2001 Controller contains High Frequency Digital Electronics and will NOT function correctly
without Noise Suppression Wires!
Note about manual transmission clutch switch/position sensor on GM vehicles:
For LNC-2001 applicable vehicles (2009-2013 Corvette ZR1, 2012-2014 Camaro ZL1, and 2009-2014
CTS-V) with manual transmissions, the clutch position is observed by the ECM through the clutch
pedal position (CPP) sensor, which will have a falling voltage output as the pedal is depressed. Because
the signal is a variable analog voltage instead of a switched 12 volt signal, the LNC-2001 cannot be
directly triggered by the sensor. For this reason, a TPS/clutch switch such as the Lingenfelter CTAP-
001 (PN: L460190108) must be wired into these vehicles in order to trigger the LNC-2001 based on
clutch position.
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-2001, 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. LPE recommends the use of our TVS diode on all vehicles that have a line lock or trans-
brake. This kit comes with three TVS diodes, enough for most common installations. If you have a
vehicle with multiple solenoids we recommend obtaining additional TVS diodes for those solenoids.
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, such as the case
with a trans-brake solenoid, 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
