Motronic 1.3 OEM Sensors Usage

• Pre CAT Lambda sensors are not used - but can be wired if needed
• AC signals from vehicle - can be used but not wired
• Automatic torque reduction - can be used but not wired
• Automatic Park or Neutral - can be used but not wired
• Torque converter clutch active switch - can be used but not wired
• Electric fan - can be used but not wired, not available in all cars.
• A/C Compressor active - can be used but not wired

• Crank sensor - used as OEM
• AFM is monitored and can be used - usually removed, the adapter harness for new air temp sensor makes it unusable
• Coolant temperature - used as OEM
• Air temp sensor - used as OEM, new air temp sensor usually replaces the oem air temp sensor as it´s fitted inside the AFM.
• TPS sensors - fit M50 TPS, no additional wiring required, if the car is automatic TPS signal for transmission controller must be wired to the adapter, ECU will then use it for TPS same for EML vehicles.
Cyl 6 spark signal - wired as cam signal, can be replaced by a cam sensor.
• Vehicle Speed Sensor Rear Right - used as OEM

Motronic 1.3 OEM Actuator Usage

• Ignition coil wiring - stock coil supported, wasted spark dumb and smart coils supported, individual coils smart and dumb supported.
• Tachometer signal
• Fuel pump relay
• Idle control valve
• Main relay
• Econometer
• Check engine light

CAN BUS Compatibility

Motronic 1.3 cars never had any canbus, the LPC8 has two canbuses which allows for near endless expansion.

LPC8 has higly versatile canbus system, discuss your requirements with PNPECU if you are unsure.

Options at ordering

Not everyone is going to need or want the same thing with their ECU conversion.

Ignition outputs
• Stock coils - jumpers in the ignition driver set to IGBT
• Smart coils - jumper in the ignition driver set to smart coils.

ECU Model
• LPC8 GEN2 DUAL WIDEBAND: 11 Analog inputs are spare, 4 Digital input are spare, 10 Low side outputs are spare, CAN1 and CAN2 are spare, 1 Relay output is spare. Adapter is wired to be Drive By Wire ready. 2 knock sensor inputs are spare

Injectors
This is a selectable option so that the webstore doesn´t incorrectly calculate shipping cost when customer wants bigger injectors
