Summary of change:
Engine: Lancia Thema 2,0 16V Turbo (834 C 1.000) Same engine type like all Fiat group 16V engines. (Fiat Coupe,Tipo,Tempra,Croma,Lancia Delta,Thema,Kappa,Alfa 155 Q4) Engines are different only in electrical components and some mechanical details. - Displacement: 1995ccm - Bore: 84mm - Stroke: 90mm - Cilinders: 4 in line - Firing order: 1-3-4-2 - Distribution: by belt, DOHC (2 cams in head) - Rotation: right Engine tuned parts: - Turbocharger: Garrett GT3076R, (internal wastegate), assumed pressure: little more than 2 bar - Throttle butterfly: Jaguar 4,0L, Diameter: 73mm - Exhaust manifold: tubular type, diameter of each pipe: 42mm - Intercooler: Water to Air type -car will be used for DRAG RACING ONLY '''Engine sensors (which will be used in my project):''' '''Crankshaft (Trigger 1):''' -'''pulley(Crank): 60 teeth -2''' -sensor type: '''VR''' (Magneti Marelli SEN 8D - '''700 Ohm''') from Lancia Delta/Escort RS http://www.vems.hu/files/LanciaSlovakia/Sen%208D.jpg '''Camshaft (Trigger 2):''' (if using wasted spark - dont need trigger 2) ** pulley: 1 tooth ** sensor type: '''HALL'''( Bosch 0 232 103 039) from Fiat Punto,Doblo,... http://www.vems.hu/files/LanciaSlovakia/Bosch%200232103039.jpg *** if you have the option, HALL sensor is a better choice than VR, because low toothcount VR sensors are more sensitive to signal conditioning (pullup, pulldown) and noise Throttle position sensor (TPS): http://www.vems.hu/files/LanciaSlovakia/Bosch%200280122001%20TPS.jpg -type: Bosch 0 280 122 001 -total resistance : cca 2 kOhm -number of wires: 3 -rotation: optional left or right (only need to swap wires) Water temperature sensor (WT): http://www.vems.hu/files/LanciaSlovakia/Bosch%200%20280%20130%20026%20WT.jpg -type: negative temperature NTC (appr. 2252 Ohm at 25°C) -mark: Bosch 0 280 130 026 -impedance at -10°C = 9 kOhm -impedance at +20°C : 2,5 kOhm -impedance at +80°C : 0,3 kOhm -voltage: 5V -number of wires: 2 Intake Air Temperature sensor (IAT): -type: negative temperature NTC (appr. 2252 Ohm at 25°C) -mark: Bosch 0 280 130 060 ( from Lancia Kappa 2,0 16V Turbo) -impedance at -10°C = 9 kOhm -impedance at +20°C : 2,5 kOhm -impedance at +80°C : 0,3 kOhm (this values are only informative, because i cant find values for this specific sensor - but i will measure it) -number of wires: 2 Manifold Absolute Pressure sensor (MAP): -VEMS external MAP sensor -Max. pressure: 400 kpa -Voltage: 12V Knock sensor: Option 1: -mark: Magneti Marelli SEN 14B -operation frequecy: 12-16 kHz Option 2: -mark: Bosch 0 261 231 006 (usualy used by VEMS) * Knock sensing is not perfectly implemented, and i don't recommend using it for now, but stock sensor should work once the functions is good. Lambda sensor (O2): -type: Wideband (5V) -mark: Bosch 0 258 007 351 (recommended by Vems) -number of wires: 6 Exhaust Gas Temperature sensor (EGT): * type: VEMS * diameter: 2mm * without amplifier. VEMS ECU (if chosen with 1 or 2 EGT inputs) does NOT need external amplifier. For VEMS v3, external amplifier only needed for more than 2 EGT inputs. Other (non-VEMS) ECU-s that lack K-thermocouple inputs (but have 0-5V or 0-10V input) need external amplifier for K-thermocouples ----- '''Engine actuators (which will be used):''' Ignition: -wasted spark type with 2 coils -Coils type: Marelli BAE 800B (060708038010) (Fiat Punto,Coupe, Lancia Delta,Thema,Y,...) http://www.vems.hu/files/LanciaSlovakia/MARELLI%20BAE%20800B.jpg -Primary coil resistance: 0,54 Ohm -Secondary coil resistance: 7500 Ohm -Spark plugs: NGK BP6ET (3 electrodes in circle) -- I would do BP6 or 7ES instead, plain copper electrode, regap to 0.4mm. (will see...) Injection: -Injectors type: Peak & Hold -Number of injectors: 4 -Resistance of 1 injector: '''2,5 Ohm''' @ 68F -Injectors mark: RC Engineering, 750 cc/min @ 43,5 PSI http://www.vems.hu/files/LanciaSlovakia/RC%20inj%20750cc.jpg -Injectors drivers: one driver per one cilinder -'''Additional series resistor for injectors''': OEM type, cca '''7 Ohm''' per each inj. (for higher flowrate, eg. 1200-2400cc low-Z injectors, the [http://shop.vems.hu/catalog/lowz-extension-channel-p-160.html low-Z extension 4channel] would be better, but at 750cc/min (where idle pulsewidth not extremely short) the gains are negligible compared to the simpler series-resistors ........'''So, if i understand it right, if i order ECU with lowZ-4channel, i cant use additional series resistors for injectors and i can plug injectors directly to ECU?''' * I would choose the low-z drivers anyway, they are fully compatible with your resistors, but give you the possibility of removing them if you like to at a later point. -Fuel pump: Bosch 0 580 254 044 -Fuel pressure: 3-5 bar Boost Control Valve: -for this time unconnected...after: OEM Solenoid Bosch or Pierburg * We now have [http://shop.vems.hu/catalog/high-capacity-pneumatic-valve-3way-p-171.html?osCsid=54b7a923c6ea25bba50728da234a7d28 a new solenoid] in stock, higher flow Display: - VEMS LCD Display (green) http://www.vems.hu/files/LanciaSlovakia/Wiring%20diagram%20%28VEMS%29%20Tomas%20Polonec%20Fiat%20127%20Lancia%20engine.jpg ---- Note from support crew: You've made '''good plans, and a nice description of your project''', include the page URL in your order comment and negotiate some '''discount''' for v3. ---- '''Note from Tomas to support crew: Thank you very much support crew! ;)''' ---- Here is my project car (the white one), which actualy runs with Lancia 2,0 16V Turbo engine with stock ECU and it is tuned for 290HP and 400 Nm. I hope with VEMS it will be better :) This is actualy result without Vems (for this time): http://www.vems.hu/files/LanciaSlovakia/Fiat%20127%20Luigi.jpg
