C-Engine)

Engine
parameters Signification
Values expected
when engine is
OFF
Values expected when Engine is
running
RPM Engine revs 0 - Idle > 1200rpm
- WaterT<50°c : RPM limiter = 4500rpm
- 50°c - WaterT > 100°c, rpm limiter decrease
progressively to reach 3500rpm at 120°c
VBatt (V) Battery voltage 11.5V to 12.5V > 13.5V
OilP (b) Oil pressure 0 >1.5b when engine RPM>3000
WaterT (°C) Water temp
#ambient temp when the
car is cold Water temp progressively increase to 87°c
(Water fan goes ON at low speed)
AirT (°C) Air intake temp #ambient temp when the
car is cold Air temp progressively increase when the car is
in static position
Pedal (%) Gas Pedal
potentiometer position 0 > 100% depending on
Gas pedal position 0 > 100% depending on Gas pedal position
Throttle (°) Throttle
potentiometer position <9°
(depends on water temp) 0> 100° depending on Gas pedal position
FBW Fly by wire status OK
OK
Manifold P Manifold air pressure Atmospheric pressure - Idle : Manifold P< 350mb
- When Water T >55°c Manifold P follows strictly
the BoostP (at 100% throttle)
Boost P Boost pressure Atmospheric pressure - Boost P < 1.1b when Water T <30°c
- When 30°c < Water T < 50°c => BoostP
increase progressively
- when water T > 50°c => BoostP can go to its
maximum value (2.1b)
VVT1_tg (°)
VVT1 target =
instruction sent by
ECU to the dephaser 0
If WaterT < 55°, VVT1_tg =0
As soon as WaterT>55°, VVT1_tg=100
VVT1_pos (°) Intake
camshaft pos :
depends on VVT1_tg 0 - After starting : automatic calibration (10sec)
- Then VVT1_pos = 100°
- when water T>55°, VVT1_pos must strictly
follows VVT1_tg
Fuel (L) Fuel level Fuel Level Fuel level
Fuel LP (b)
Fuel press
(measured at the
exit of the fuel cell) 0b / 5b maxi when “fuel
pump” button is pressed 4.7 Fuel HP (b) Fuel press (HP rail) <10b - 18b < fuel HP <180b
-If fuel HP < 15b during starter excitation, the
engine will not start, it’s necessary to bleed the
air inside of the rail
(see procedure in chapter
C-Engine)
Water Fan Water fan speed OFF
(depends on water temp) LOW (Low speed) when Water T >87°C
OFF when Water T <86°C
HIGH (High speed) when Water T >90°C
LOW when WaterT <88°C
See chapter
C-Engine
Turbo Fan Turbo fan OFF
(depends on Air temp) ON if Air temp is > 50°C
OFF when Air temp is <48°C
Waste Gate (%)
Waste gate duty 0
Depends on Boost pressure target
Must always be under 70%
Pop off (%) Pop off valve pos 0 (close) - 100% (open) after an complete closure of the
throttle and Boost P > 1400 mbar (to reduce the
pressure upstream to the closed throttle)
- 100% if WaterT <50°c
ID Not used

For reliability reasons and to avoid alarms risings,
it’s strongly
recommended to let the engine warm up to a water temp > 60°C
before any practising. If this condition is not respec ted, the full engine
power won’t be available.

B.6.3.4 Alarms displayed on the dashboard

Alarms are generated by the ICD depending on engine / gearbox sensors values sent by
the ECU for display.
The alarm/default message disappears only when the problem is solved. Even if the
problem is solved, till the power supply is ON :
- The top left and/or right LEds alarms remain ON
- The letter in the area “event” is displayed

We distinguish 2 categories of alarms : A and B
B.6.3.4.1 M
AIN ALARMS (CATEGORY A)

The following alarms are displayed to the driver, m eaning that he must immediately
stop the car and cut the engine.
o Water T max
o Oil P min
o Vbatt min

See List on next page with the corresponding thresh olds.

A message is displayed on the full screen on the da shboard + in the Area ‘Default” to
force the driver to stop
In addition with the message displayed, all the fol lowing LEDs become RED:
- 3 on the Right column (above gearbox diagnostic L ED)
- 3 on the Left column (above engine diagnostic LED )
+ 1 engine alarm LED in RED

B.6.4 BASIC PROCEDURES
B.6.4.1 Power-up

Press the “ON” button of the facia switch panel
(See B.6.1) to power supply the vehicle
The “COSWORTH” home page appears when the dashboard display first comes on, and
then moves to the first driver page (RACE Page)
B.6.4.2 Starting

Once the vehicle’s electrics are on, flick the vehi cle's “IGNITION” switch to the up (ON)
position.
Check that no gear is engaged (the letter “N” is di splayed on one of the display screen’s
driver pages).
Press on the “START” button without touching the Gas Pedal


The vehicle will only start if the following elect ronic equipments are connected
and are working properly:
- ECU
- CBNT
- Master relay
It is possible to start without plugging the dashbo ard
NOTE :
For the first engine start after engine refitting, it’s necessary to bleed the fuel
rail. To make it properly, please follow carefully the procedure indicated in chapter C-
Engine

B.6.4.3 Turning off the engine

Flick the “IGNITION” switch to the down (OFF) posit ion

NOTE : The vehicle’s electrics remain switched on
Except in the event of an emergency stop, it’s stri ctly not advised to turn off the
engine using the power supply switch (OFF button).
It is also recommended to wait 30seconds between sw itching off the engine and
switching off the power supply.
Respecting these two recommendations will guarantee optimum operation of the power
steering.
B.6.4.4 Switching off the power supply

Press the “OFF” button of the facia switch panel an d hold there for at least half a second.
The dashboard display is switched off.
NOTE: Switching off the power supply also switches off th e engine.

B.6.4.5 Changing gears

2 modes are possible and are completely independent . It’s possible to make randomly
upshift and downshift manually (using the lever) or in semi-auto using paddle shift kit.

Please refer to Chapter D-Transmission/shifting for a complete description of the shifting
modes.
B.6.4.6 Pit limiter

The purpose of this function is to limit the vehicl e's speed to 60kph
. It is enabled and
disabled by the driver.
Principle:
By pressing the button “PIT” of the steering wheel, Engine revs are thus limited (by the
ECU) to those corresponding to a speed of 60kph and the message “PIT LIMITER” is
displayed on the dashboard in the RPM Area :
