B.6.3 DASHBOARD: COSWORTH ICD 01D-032954-RST

B.6.3.1 Pages


The display contains 8 pages classified in 2 differ ent families :
- Family 1 : 3 “driver” pages
-
Family 2 : 5 “diagnostic” pages
B.6.3.1.1 D
RIVER PAGE 1 : RACE PAGE


Area “LAP” :
Time : Current lap time (stay displayed 10s after having being cut)
Lap # : number of lap completed during the RUN
Area “Speed” : Current speed displayed (depends on tyre diameter, configurable in Toolset (see
chapter G - Softwares )

Area “Default” :

When 1 or several defaults appear, they are scrolli ng on this area when the default is still
present.
NOTE :
Even if the defaults disappears (Oil_P min, or GB_p ot_def for example) :
- A letter in the area “Event” is recorded depending on the kind of default.
- A alarm LED appears on top right or top left positi on (engine or Gearbox alarm)

Area “Event: Each letter means that during the last or current R UN, an
alarm was recorded (even if it disappeared after) t o
encourage team to check the default.
W : Water temp alarm recorded (min or max)
O : Oil pressure recorded (min or max)
B : Battery voltage recorded (min or max)
E : engine alarm recorded (other engine sensor than W, O, B)
G : gearbox alarm recorded

Default
Engine alarm LED
Gearbox alarm LED

Area “MAP” “DRY” or “WET” depending on the engine MAP selected on the Facia switch panel

Area “GEAR”
Corresponds to Gearbox ratio engaged (R, N, 1, 2, 3 , 4, 5, 6)

Area “RPM” Current engine speed in RPM (“xxxx RPM”)
Area “RAIN LIGHT”
“OFF” (grey background) or “ON” (green backgound) d epending on the Facia switch
panel interrupter position.
Area “Engine”
Engine oil pressure (bars)
Engine water temperature (°C)
Battery voltage (V)
NOTE :
these 3 Values corresponds to the Category A alarm s

B.6.3.1.2 D
RIVER PAGE 2 : QUALIFICATION PAGE



Area “LAP”, “Speed”, “MAP”, “Events”, “Default”, “r ain light”, “RPM”, “GEAR” and “alarms
LED” remains the same as the RACE PAGE. Only the “S plits” replace the “engine” area

Area “Splits” This Area represents the Qualifying mode (QM) confi guration

- Time difference : current split compared to split recorded from
the best lap
- Bargraph : 1 bar = 1 tenth (+/- 1 sec)
- Split : Current split time : reference


NOTE :
Refer to chapter G-Softwares for the full Qualifying mode configuration

Engine diagnostic parameters
: (see also chapter
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.

DIAGNOSTIC PAGE 4 : CBNT DIAGNOSTIC (PAGE 1/2 : STATUS)



Every indication corresponds to the XAP CBNT pinout and shows the status
(OK / FAULT)
of each Pin (one Letter = A, B, h, g…etc = 1 Pin). All values must be “OK” (green).
When “FAULT” appears, the Pin is not correctly supp lied. Please refer to chapter F- wiring
for more details.
