The circuit is based on MegaSquirt 3 and pinout of the KdFi1.4 modules. Making the SM3 backwards compatible with the MS2 KdFi1.4 users and boards. It was refined and build 100% AEC-Q100 compliant. A KPerformance Wideband Lambda Controller is also part of the SM3 board. A Bosch LSU 4.9 sensor can be connected directly without a extra controller. Included in Delivery SM3+ Module/KdFi and/or additional PCB USB plug* User manual Software Recommended tuning software TUNERSTUDIO and/or Megalog viewer USB Driver The onboard FTDI chip simulates a serial RS232 connection: TunerStudio Communications Settings: USB and Wireless (only in registered Version), Auto , 115200 Baud 2 Motronic DIY Base r2 User Manual Kperformance USB Port The Motronic DIY is smart, it will automatic revert to master USB connection as soon as the USB cable is plugged in! Without USB connection it will switch to Bluetooth(if installed). The USB chip is downwards compatible, it can be used both with USB 3.0, 2.0 and 1. Each standard USB cable can be used as connection cable, but preferable with FERRIT core further avoiding ESD spikes. Electrical connections Like all other voltage supplied parts - must be preceded by a fuse in function of cable section. Recommended cable types: Ignition: min 1.5 mm² Injection: min 1.5 mm² VR sensor: min 0.5 mm² Shielded Sensors: min 0.35 mm² Others: min 0.35 mm² Fuses Recommend using a 3A fuse for protecting the SM3. A automated 5A PTCC fuse is integrated on the board. It will reset itself after cooling down/solving issue or short circuit. 3 Motronic DIY Base r2 User Manual Kperformance Board Layout 4 Motronic DIY Base r2 User Manual Kperformance Pinouts KdFi Pin Label IGN1 IGN2 IGN3 IGN4 IGN5 IGN6 INJ1 INJ2 INJ3 INJ4 INJ5 INJ6 IGNA1 IGNB1 IGNC1 IGND1 IGNE1 IGNF1 12v GND FP FDLC FDLO RPM1 GND_RPM RPM2 IAC1 IAC2 AIR 5 In-/Output Function IGN output IGN output IGN output IGN output IGN output IGN output INJ output INJ output INJ output INJ output INJ output INJ output IGN output IGN output IGN output IGN output IGN output IGN output Power input Power Input Fuel Pump FIdle Valve Output FIdle Valve Output Trigger input GND VR input Trigger input General Output General Output Sensor input Passive coil cylinder 1 Passive coil cylinder 2 Passive coil cylinder 3 Passive coil cylinder 4 Passive coil cylinder 5 Passive coil cylinder 6 Injection valve 1 Injection valve 2 Injection valve 3 Injection valve 4 Injection valve 5 Injection valve 6 Active coil cylinder 1 Active coil cylinder 2 Active coil cylinder 3 Active coil cylinder 4 Active coil cylinder 5 Active coil cylinder 6 Input Voltage 8-16V Input Voltage GND Fuel Pump Relay Idle controller 3-pin -CLOSED Idle controller 3-pin -OPEN Input speed Crankshaft Ground speed sensor Input speed camshaft General Output 1 max2A General Output 2 max2A Air temperature sensor Motronic DIY Base r2 User Manual Kperformance CLT Sensor input Coolant Temp sensor input TPS Sensor input Throttle Position Signal OXY Input Lambda sensor signal bank 1 OXY_2 Input Lambda sensor signal bank 2 LSU BLACK O2 Sensor input Bosch LSU BLACK LSU YELLOW O2 Sensor input Bosch LSU YELLOW LSU RED O2 Sensor input Bosch LSU RED LSU GREY O2 Sensor Heating Bosch LSU GREY LSU WHITE O2 Sensor Heating Bosch LSU WHITE LSU GREEN O2 Sensor input Bosch LSU GREEN 5V Sensor Supply 5V Power Supply TBL Input Table Switch Additional P1 connector pinout SM3 (see image pg7) EGT+ K-Type Input EGT sensor input+ AIN1/Flex Analog Input General analog input AIN2/JS12 Analog Input General analog input PP1 Analog Input General analog input PT4 Spare CPU pin !!!Direct CPU pin!!!

EGT sensor input- Engine Speed Measurement 1. VR Sensor The measurement via VR sensor is the most widespread way in Europe for car engines. An AC voltage is induced in the coil of the VR sensor by a trigger wheel with 60-2 or 36-1 tooth. Connect VR-1N & VR-1P and/or VR-2N & VR-2P. 2. HALL sensor may require a pull-up resistor of 1k to 10k ohm between signal-out and +5V. Leave VR-1N & VR-2N floating (do not connect) Please use the DIP switches to activate HALL-sensor Pull-Up's Throttle Potentiometer The throttle potentiometer is connected up by a 3-wire cable. +5V and GND are connected to the outer static pins of the potentiometer. The voltage relating to the throttle position is tapped via the sliding contact and connected to the input TPS (Throttle Position Sensor). The covered distance of the potentiometer may be longer than the rotation of the throttle axle. The corresponding calibration is done via "Tools" "Calibrate TPS" Digital Inputs 7 Motronic DIY Base r2 User Manual Kperformance There are digital inputs that can be used for example as "Launch Control". The corresponding function has to be defined in TunerStudio. Spare CPU pins BE very careful when using these !!Direct CPU Pins!! they have no RC-filtering nor safety components. Incorrect usage can destroy CPU inputs, Preferable use GND activated inputs Analog Inputs There are analog inputs that can be used for example as "Additional temp". The corresponding function has to be defined in TunerStudio. Idle Speed Controller (Fidle) Supports both the 2-pin and the 3-pin idle speed valves. Pin connections of the idle speed control: 2-pin: +12V & FDLO 3-pin: +12V & FDLO (open) & FDLC (closed) The FDLO & FDLC are automatic inverted on the PCB, use Fidle control under TunerStudio, Ignition 8 Motronic DIY Base r2 User Manual Kperformance The Passive ignition coils can be activated by the integrated power drivers the PCB is equipped with 6 power drivers enabling sequential activation of passive ignition coils. The active coils can also be activated, by using the active coil solder pads. Injection There are 6 injector outputs (INJ1-6) ; The injection valves are supplied with +12 V via the ignition switch and the ground wires of the injectors are activated via the SM3 Attention: The setting whether the injection valves are of high or of low resistance has to be entered in Basic Settings" "Injector Characteristics" strictly before the first test run because wrong settings can cause destruction of the injection valves or of the SM3a. Starting values (no guarantee): High impedance: PWM Current Limit (%): 100 PWM Time Threshold (ms): 25.5 Low impedance: PWM Current Limit (%): 30 PWM Time Threshold (ms): 1.5 Bluetooth or Wifi Connection Optional bleutooth or wifi connection only in combination with Full SM3+ ECU Onboard Wideband Lambda Controller 9 Motronic DIY Base r2 User Manual Kperformance A Bosch LSU 4.9 sensor can be connected directly without the need to buy a further controller. Starting of the controller is done by: · activating DIP switch GP2-GND · activating DIP switch OUTO2-OXY1 Calibration data TUNERSTUDIO custom linear wideband: 0V = Lambda 10.20 = AFR 22.35 5V = Lambda 0.650 = AFR 9.50 Onboard Knock The knock IC uses a purpose designed knock sensing amplifier chip to filter knock signals. Knock Wiring: Knock Sensor1-> Knock1 ECU input and ECU ground Knock Sensor2-> Knock2 ECU input and ECU ground Onboard datalogging The board is equipped with 1Gb of onboard SMD-sized memory. Ready to be used under SD datalogging menu Onboard RTC (real time clock) 10 Motronic DIY Base r2 User Manual Kperformance The board is equipped with a very accurate RTC, giving the possibility to add 'time stamps' to the onboard data logging feature! Making data logs easier to read, easier fault and/or tuning improvements. CAN Bus Like MegaSquirt the CAN Bus hardware is populated on the board, but has to be programmed accordingly by the user if desired.
