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 ---- Genboard unit specification: Serial no.: 1433 pump- = 4.12 V wbo2pumppwzero = 0x66 (102) wbo2 nernstdctarget = 0x86 (134) pump+ = -3.5 mV/200 ohm AREF = 4.9 V ---- Calibrated values: Map sensor offset (kpa) = 6 WBO2 calibration constant = 199 *Differs for every sensor. Adjust until O2% on mlp07 is 20.95%: mde02 turn the heater on: mde00 turn the heater off PUMP PID nernst target = 134 Problem at egt calibration: *In boiling water vems shows 84 C with egt1_cal= 0x49. In water/ice shows 0 C every time, NOT depends on egt1_cal. There is no egt1_offs in config as PhatBob user guide said. *How calibrate the egt sensor correctly? ---- '''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 Ford Escort/Mondeo wasted-spark coil is good sollution against the original distributor+coil setup '''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) * Seems to "bleed-type" valve with two stages (In L8 P8 ECU there is possible pwm control) ---- Configuration advice: * Original VR sensors are usable, choose "auditrigger" option for the assembled ECU (EC36pin27 for primtrig VR, EC18pin12 for sectrig VR) * Recommended firmware: 1.1.27 with Lancia/Cosworth trigger setup ** do you have a full proven config + tables ? *** See KarolyBakos, but there is a crank pulse widht bug in 1.1.27 * Recommended 30V flyback (or at least power flyback, not low voltage flyback) ** With original injector + 6R8 serial resistor ** Or with high Z injector * 4+4 IGBT option ---- '''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. ---- See KarolyBakos
