The LC Engineering Pro Fuel Injection System will give you total control over the fuel and ignition curve of your engine. This system can be programmed to handle unlimited engine modification, performance options and environmental changes. With this level of performance, careful engine tuning is required. Keep records on what your settings are and what changes you make. This will give you a reference tool regarding the setup you use for your system.
NOTE: Improper ignition timing and/or setting the fuel mixture too lean or too rich will damage your engine.
Throttle Position Sensor Installation Instructions:
Connect the SDS wiring harness TPS wires to the stock Toyota 85-95 TPS Switch. Unscrew the TPS switch and reposition it pointing toward the fire wall for wire layout convenience. We recommend soldering and shrink wrapping your wire connections to ensure a strong connection that will not loosen up over time. We also recommend testing your throttle position sensor and replacing as needed. It can be very frustrating to track down a running issue when it is caused by a bad TPS. LC Engineering also has a TPS mounting kit that consist of allen head screws and a with a ball headed allen wrench for easier accessibility and adjustment.
Connect wires as follows:
- Red Wire = Vcc
- White or GreenWire = VTA
- No Wire = IDL
- Black Wire = E2
