Brefore running: check / set gearbox potentiometer

To avoid damage to the gearbox, the potentiometer setting need to be checked (or corrected)

before each running of the car

Check potentiometer: - switch on main switch and ignition

- engage neutral (N) in gearbox

- switch dashboard to page 5 and check value “gearpot“

- value should be 850 mV 10 mV

Set potentiometer: - if value “gearpot“ is out of range it need to be adjusted

- loosen fixing screws

- turn potentiometer until dashboard shows 850 mV

- tighten screws

R8 LMS Handbook

Before running: fuel / cooling fluid

Before running the engine check level of all fluids:

FUEL

Quality: 98 ROZ unleaded or gasoline > ROZ 98

95 ROZ usable with powerloss, not for race purposes

Tank capacity: max. 120L

COOLING FLUID

Coolant: equivalent to VW G12 ++, specification N.052.774.G0

mixture 40 / 60 (coolant / water) for -30°C

mixture 30 / 70 (coolant / water for -25°C

Recommended XXXXXXXXXX for max. cooling

Capacity: 14,5 L total

Checking fluid level: Level must be checked with cold engine

R8 LMS Handbook

Cooling fluid

minimum / maximum

Before running: engine oil

ENGINE OIL

Type: Castrol EDGE FORMULA RS 10W-60

Alternative: Shell Helix Ultra Racing 10W-60

Capacity: first filling (dry engine) 11,8L

refilling (oil change) 8,5L

Filter 0,3L

Check oil level: - put the car on a flat, even surface

- run engine (see Warm-up) until oil temperature reach 100°C to 110°C

(watch dashboard)

- keep engine running on idle speed for about 2 minutes

- switch off engine and check oil level after approx. 2 min time

- oil level in “Fill“-area: fill up 1l of oil until level is in “Do not fill“-area

- oillevel has to be in the upper third of ”Do not fill “(2) area

Refill: - fill up 7l

- run engine on idle mode for about 30s

- fill in 1,5l

- warm up engine to 100°C and check oil level again (see above)

R8 LMS Handbook

Brefore running: gearbox oil

GEARBOX OIL

Type: Castrol SAF XJ 75W140

Capacity: 3,5l with dry gearbox-oil-cooler

3,0l with full gearbox-oil-cooler

Check oil level: - new or revised gearboxes have to be runned about 2 minutes in neutral (N)

- after that bring gearbox temperature to a minimum of 60° (see Warm-up).

- use dip stick to check oil level, the dip stick has to be covered up to the upper

end of the marked area

R8 LMS Handbook

R8 LMS Handbook

Warm-up preparation

• Please ensure that the complete car is in roadworthy condition and stands on flat surface

• Remove engine bonnet

• Lift the car with the air-jack system and mount the safeties

• Check the level off all fluids (see engine and gearbox setup)

• The battery has to be charged and/or should be connected to a charging station

• Mount the start-up-wheel-hub at the rear axle

• Check the gearpotentiometer value in neutral position (850 mV)

• Care for a good ventilation in the pit box / garage …

• Main switch on, then ignition on

• Switch ASR off = switch to position zero (far left)

• Connect the Lite-XS Cable into the plug at the drivers door, read out the failure memory of the car via

DIAGRA-LE, if necessary delete it. But keep in mind, that some adaption values are zero after

deleting the failure protocol

• Ensure that the neutral gear position is engaged

R8 LMS Handbook

Warm-up / Cool down of engine & gearbox

Warm up procedure

• Start the car -> Press the clutch and the start button

• Shift up to the sixth gear (see Upshifting)

If the gearbox is cold (t_gearbox < 50°C) it is better to use the clutch for upshifting to 6th gear.

• Heat up engine oil with ~2500rpm in sixth gear to ~ 60°C

• From this point continue with 3500rpm until the gearbox oil temperature is ~ 60°C

• Have a look at the water temperature, it should not rise above 115°C,

if necessary put a fan in front of the car

• Check that the fan in front of the water radiator starts to rotate at 100°C

Cool down procedure

• Shift down from sixth gear to neutral (see Downshifting)

• Run the engine 2 minutes in idle speed

• Switch off ignition, the engine stops and switch on ignition again without starting the engine

• Wait one minute and check the oil level of the engine (see Engine setup)

• Visual check of all fluid levels

• Inspect the engine in matter of leakages, damages, electrical and wiring problems

• Connect the Lite-XS Cable into the plug at the drivers door, read out the failure memory of the car via

DIAGRA-LE, if necessary delete it.

• Switch of Ignition and main switch

Shifting

Generally

• Before driving heat up gearbox to a minimum of 60° (see Warm-up)

• For upshifting you have to apply a minimum of 10% throttle!

• For downshifting you have to be off throttle!

• Watch display for gear engaged

Upshifting

• Use clutch for

– Shifting from neutral to 1st gear

– Shifting from reverse to neutral

• Do not use clutch for

– Shifting up from 1st gear to 6th gear

Downshifting

• Use clutch for

– Shifting from 1st gear to neutral

– Shifting from neutral to reverse

• Do not use clutch for

– Shifting up down from 6th gear to 1st gear

R8 LMS Handbook

Shifting

Shifting problems

• If you are stuck between two gears, what may happen e.g. caused by a dog to dog situation

- press clutch

- apply shifting paddle in the direction you want

- release cluch gently

- carry on shifting without using the clutch

• If you are not able to shift in neither direction:

- use switch “Gear Shift Emergency“ on dashboard. This mode will enable you to continue shifting

bypassing the sensor input values

- for upshift use no clutch

- for downshift without clutch a throttle blib need to be applied manually. If this is not possible, use

clutch

- return to the pit and check compressor, shift-cylinder and gear potentiometer

R8 LMS Handbook

R8 LMS Handbook

Pitspeed limiter

Pispeed Limiter handling / setting

• The pitspeedlimiter is activated by pushing the “cruise control“ lever to the front.

• It limits the revs in first gear to 4880 rpm ± a configurable offset value so you can apply full throttle

without overstepping.

• A warning will appear on the first three DDU-pages.

• To deactivate the limiter push back the lever.

• To set the offset value do the following steps:

– open Diagra_LE

– open "motorelectronic 01"

– open "10 - adaption"

– open "channel 1" – "vstnls offset neutral/idle set speed "

Factory setting is a speed of 4880 rpm

– on "test value" enter an offset. For example „-100“. Click „test“ – „save“ – „yes“

– now the neutral / idle set speed is saved by 4780 rpm. The pitspeed in first gear is now a

little bit slower as factory setting. 100rpm ≈ 1,239km/h

– with "read" you are able to check the actual entry

– make the same procedure also with „motorelectronic 11“

– The value in both motorelectronic devices have to be the same!
