Summary of change:
---- '''Wheelspeed''' v3.8 or older PCB ? InputTrigger/WheelSpeed (and GenBoard/VerThree/Schematic ) ) * '''Wheelspeed 1''' (PS2 clock pin). On v3.8 onboard protection (SMD resistor, diode), on older throughole components can be installed at PS2 header * '''Wheelspeed 2''' SCL pin. Needs protection of course (0/5V signal. No negative, or +12V on CPU pin please :-) If/when ordering assembled ECU, request "2 wheelspeed input", made for no extra charge. ---- Have been using a vems 3.6 for 3 years now, and quite happy with most of it. But with my latest engine modifications do I reuire more outputs, and want to integrate additional connectivity. So It's time for a brand new and expanded VEMS. So I have the following HW: VEMS bare SMD board unconfigured v.3.8b ETC/DBW board for additional 6 high current outputs 2x VR to Hall wheel speed dividers Airconsole Vlan/BT/USB interface 12V-5V converter for the airconsole. My planned configuration is: 8+8 drivers for 6 coils and 6 primary injectors, 4 spare High current fets used for fan1, fan2, fuel and pwm control of Exup valve. one knock channel Primary VR, secondary Hall Stepper output for Idle air valve 2x lambda 4.9 2x wheelspeed one from gearbox and one from front abs sensor DBW 6 fet outputs connected to P259 used for 6 secondary injectors. Engine is a heavyly modified Jaguar AJ30 duratec with 285 deg high lift cams and 6 ducati ITB's. Redline at 9000 rmp with aprox 330 hp. For the questions: I need to configure the SMD PCB and it seems that 3.8b differ a bit from the 3.3 documentation I can find. Fet's, flyback RS232 knock is pretty straight forward. But can you help me with HW setup for the dual wheel speed input ? And did anything change on the dual lambda setup, for 2x LSU4.9, compared to v3.3 ? I will add an aitional EC18 connector to the case and pin the secondary injectors and wheelspeed input there
