Summary of change:
Replaced stock Bosch Motronic M2.10.3 with VEMS 3.6 to use racing camshafts. Stock wiring is used for installation, so I had to use Motronic 55 pin connector and VEMS GenBoard. Also some very small adjustments to stock wiring were applied for MAP sensor instead of MAF. Original primary sensor (VR, 60-2) is used for triggering; secondary sensor and phase variator are disabled (no reason to use them for racing engine). Items used: * Vems GenBoard v3.6 * Alubos case with motronic55 frontplate * 8 x Ignition driver * 10 x Injector or WBO2 heater driver * Idle stepper motor driver * Wideband connector * Dual channel knock sensor interface * EGT amplifier chip Additionally were bought: * Wideband sensor * Cheapest external MAP sensor I've found from Reanult Logan. Wiring diagram for GenBoard and Motronic connector: http://www.vems.hu/files/ACH/VEMS%20pinout%20for%20Alfa%20145.jpg There are two changes in original wiring here: * MAF connector is cut and replaced with 3 wire MAP connector * Narrow-band lambda probe has been replaced with wide-band sensor. 3 wires are attached to unused pins on Motronic connector , 2 power wires for heater connected to original lambda connector Several files important for installation (some documents are copied from other pages, just want to keep all related stuff in one place) * [http://www.vems.hu/files/ACH/alfa%20145%20latest.vemscfg Basic VEMS config for starting engine] * [http://www.vems.hu/files/ACH/Injection%20&%20Ignition%202.0%20TS%2016v%20-%20Motronic%20M2.10.3%20.PDF Original Alfa 145 2.0 wiring] * [http://www.vems.hu/files/ACH/vems_v3_documentation.pdf VEMS v.3 documentation for soldering GenBoard] * [http://www.vems.hu/files/ACH/v3_top_channels_and_pins.jpg Output channels and transistor placement] TACHOMETER NOTE: don't use +5/+12V output to drive tacho, you can control it using grounding (i.e. any ignition/injection output, e.g. EC36-PIN9). If u use suggested standard VEMS tacho output, you'll fry P259 chip.
