Engine: Lancia Thema 2,0 16V Turbo (834 C 1.000)
- 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
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):
- Option 1:
- pulley: 1 tooth
- sensor type: VR (Magneti Marelli SEN 8D – 700 Ohm) from Lancia Delta/Escort RS
- low toothcount VR sensors are more sensitive to signal conditioning (pullup, pulldown) and noise
- Option 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
Throttle position sensor (TPS):
-type: Bosch 0 280 122 001
-total resistance : cca 2 kOhm
-number of wires: 3
Water temperature sensor (WT):
-type: negative temperature NTC (appr. 2252 Ohm at 25C)
-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 25C)
-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
-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)
.........Which knock sensor will be better? I preffered Marelli, because it is stock sensor used by Lancia...but if i cant use it for Vems, i can change it with Bosch one.
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)
-Primary coil resistance: 0,54 Ohm
-Secondary coil resistance: 7500 Ohm
-Spark plugs: NGK BP6ET (3 electrodes in circle)
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?
-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
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.
Thank you support crew ;) But before i order my V3, i have some questions...i send an e-mail to info@vems.hu and waiting for answer.
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:
