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
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,...
- 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):
-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):
-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,...)
-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
-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 [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 [a new solenoid] in stock, higher flow
Display:
- VEMS LCD Display (green)
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):
