Summary of change:
Ford Sierra Cosworth 2wd * '''4 cylinder inline engine, with fire order 1,3,4,2''' * displacement: 2L Originally with Weber-Marelli engine management. See InputTrigger/LanciaCosworth ---- '''Other sensors''' - seems very smooth The Throttle Position Sensor (TPS) This unit is fitted to the throttle shaft and senses the throttle position. at idle speed voltage is 5.0-4.5 volts and at full throttle the voltage drops to 0.5 volt. The Manifold Absolute Pressure (MAP) Sensor Depending on the manifold pressure, the sensor regulates between 0.25 to 4.75 volts. * If manifold pressure exceeds 0.9 bar, the sensor signals the ECU to cut-off fuel ** the threshold is just configured in the ECU, no plus wire. The Air Charge Temperature (ACT, MAT) Sensor This sensor is of the NTC resistor type, its resistance decreases as temperatures increase. Engine Coolant Temperature (ECT, CLT) Sensor The ECT is also of NTC resistor type and its operating range is identical to that of the ACT. ---- '''Actuators:''' Ignition module The ECU sends a Spark-out signal to the ignition module * by factory it's a simple distributor+coil setup, not wasted spark ** is it allowed to use wasted spark or COP / CNP ? The trigger does allow, but do the racing regulations also allow ? *** Engine is not homologed now. But in hungarian rallyecross this engine is running with wasted-spark configuration nowadays. * sounds like ECU needs to be ordered power (IGBT) output and dwell is controlled by ECU * dwell is totally governed by the module and cannot be adjusted, unfortunatelly no more data about ignition module * module input signal is ** logiclevel ?? ** or power signal (pulled to GND) ? '''Coil''' - would you really want to use the unknown ignition module when this coil could be driven directly ? * Bosch, high output breakerless ignition type * output 25.0 kV (min) - open circuit condition * primary resistance 0.7-0.9 ohm * secondary resistance 4500-7000 ohm '''The Fuel Injectors''' The ECU provides accurate control of the solenoid operated fuel injectors to discharge fuel. *The type of the standard injector is Weber/Marelli IW025, low impedance. So power resistor recommended. *Flow rate is approx 311 cc/min or 297 cc/min (not found exact spec.) at 3 bar fuel pressure. The '''Idle Speed Control (ISC) Valve''' This unit is regulates the engine demand for air depending on the engine temperature, engine load, or swithed on accessories. The valve, whichis controlled by a variable current from the ECU, adjust the air flow into the engine. The '''valve is pwm modulated'''. The Boost Pressure Control Valve This solenoid valve is directly connected to the high pressure side of the turbocharger by a hose. Depending upon whether the valve is open or closed it will either "vent-off" a portion of the boost to the inlet side of the compressor (valve open) or direct it to the wastegate actuator (valve closed) I need some advice about the hw configuration of vems. * Can I use this VR sensors? ** yes * Is this Vr sensor configuration suitable for VEMS? ** not in this form without firmware modifications * What type of ignition driver configuration do I need? ** sounsd like IGBT, but more info on the "ignition module" is needed to tell for sure. Since only 4 cyl, 4+4 can be a good bet to suit either. * Do I need power flyback? ** recommended. About analog / digital inputs From wiki and WebShop docs there are 3 spare analog input: EC18pin6 is set up for electronic MAP signal when no onboard MAP sensor is used. Otherwise EC18pin6 set up for MCP3208pin7, that is channel6 of the extra-ADC. USABLE because of onboard MAP EC18pin12 is set up for secondary_trigger VR when auditrigger is ordered. Otherwise EC18pin12 set up for MCP3208pin8, that is channel7 of the extra-ADC. NOT USABLE because of auditigger :( EC18pin16 is set up for MCP3208pin6 (channel5 of the extra-ADC) when 1-wire option is not selected (only after 2005 December). When will be the ibutton implemented? What features of it? * Is possible to order genboard with ibutton feature but not wired? ** it is possible to remove a 33 Ohm resistor, but how is the 1-wire useful at all than ? Maybe separate wire through endplate ? ** The ibutton use this analog input or a separated IC work with signals? (Installed ibutton for future using but not wired now) Or MCP3208pin6 would be routable to another econoseal pin? * yes, request so. Eg. instead of knock GND (EC18pin2 ? see WebShop text for the assembled controller) * EC18pin8 or EC18pin 17 is reserved? (If I need the knock sensor) What is the sollution for more analog / digital inputs? (For launch control, als on/off, fuel pressure sensor, oil pressure sensor etc.) We will make it possible to allow 3 digital inputs via 1 analog input (using a 10k ladder, pulling towards GND via 10k/4, 10k/2 and 10k. Pullup is 2k7 towards 5V, can be internal). Analog inputs are loggable. The MCP input could get electrical protections in the case? * Normally they are quite sensitive. Some more protection possible if you insist, request so.
