Fuel System 5
•Press and hold “Fuel Reset” on steering wheel for session reset
•Continue to hold for total reset
•Fuel drain procedure:
•Connect to Staubli dry break
•Master switch on
•Press “Lift Fuel” on keypad
Fuel reset procedure:
•Max. capacity - 103L
•Collector capacity - 7L
•External post pump filter - 10 Micron
•Baseline average consumption - 0.70 Ltrs / Km
•Fuel multiplier in dash:
1. Save current dash configuration to disk
2. Calculate actual consumption = (fuel in - fuel out)
3. Calculate actual fuel usage = actual consumption / No. laps
4. Calculate error factor = (dash consumption –actual consumption) / actual consumption
5. Identify current fuel multiplier in Dash Manager. “Calculations”, “Fuel Prediction”
6. Calculate new fuel multiplier = current multiplier / (1 + error factor)
7. Rename and save dash configuration to disk before sending to car

Oil dip procedure:
1. Oil temperature at 75°C (+/- 5°C)
2. Hold engine revs at 4000RPM for 10 seconds
3. Turn off the engine using the STOP button on the switch
panel keypad
4. Measure the oil level as quickly as possible after turning
off the engine
5. Adjust the oil level if necessary using the dip stick guide
Oil measurement:
Oil catch tank:
•Ensure catch tank is drained after every session
•Measure oil out of tank to calculate oil usage per hour

Engine Run Procedure 10
•Ensure car is sat on High stands or Air jack safeties. Skates as a minimum (Not hub stands, wheels or Air jacks)
•Install run up hubs. Rear wheels as a minimum
•Check engine coolant level
•Ensure water header tank, engine oil and engine oil catch tank caps are installed
•Turn master switch on
•Plug in jump battery
•ABS to position 12, TC to position 0
•Cycle through to main dash warm up page
•Crank for oil pressure (No ignition)
•Ignition on (Check for fuel pressure)
•Crank for engine start
•Let engine idle and systematically check the following systems for leaks: Fuel, Engine oil, Engine coolant, Transmission oil
•Run engine until engine oil temp reaches 75°C (+/- 5°C)
•Water radiator fans will turn on at 90 °C coolant temp, and turn off at 85 °C (Fans will not run when wheels are rotating)
•Hold engine speed at 4000 rpm for 10 seconds
•Kill engine using “STOP” button
•Measure engine oil level as quickly as possible
•Adjust the oil level and re-fit cap (Repeat oil dip procedure if required)
•“START” car and let the engine idle for 10 seconds
•Shift through all forward gears
•Hold 6th to build gearbox temperature (Ensure not to exceed 93-95 °C coolant temperature)
•Shift back to neutral
•Kill engine using “STOP” button
•Leave master switch on for 1-2 mins after engine stop. (Keeps water pumps running to prevent internal hot/cold spots)

Engine Temps/Pressures 11
•Stabilised temperatures and pressures should fall within the values shown
•If temperatures are too low, tape the radiator ducts vertically from the inside edge outwards
•If temperature are too high, reduce engine rpm until the temperature reduces

•Compare “Engine Oil Pressure” with “Engine Oil Pressure Warning Minimum Value”
•When minimum value > oil pressure investigate cause
•Start with checking correct oil level and dip procedure
•If persistent use low rpm through problem area of circuit
•Contact Ginetta if unsure about any parameters

Ride Height Adjustment 19
Measurement:
•Ride height is defined as the distance between the ground and the
cars floor (Not plank)
•Correct measurement location shown below:
•Front: level with Front axle centre, just behind nylon skid
•Rear: level with Rear axle centre, on flat section of floor
Adjustment Pushrod length change Front Ride height change Rear Ride Height change
One flat on adjuster 0.5 mm 0.86 mm 1.40 mm
Half turn on adjuster 1.5 mm 2.59 mm 4.20 mm
Full turn on adjuster 3 mm 5.18 mm 8.40 mm
Half turn on lower rod end 0.6 mm 1.09 mm 1.78 mm
Full turn on lower rod end 1.3 mm 2.18 mm 3.56 mm
Adjustment:
•Raise car on air jacks (ensure safety's or skates are in place)
•Loosen pinch bolt on pushrod
•Turn adjuster by required amount (Refer to table below, 22mm spanner)
•Ensure no more than 13mm thread showing
•For more adjustment reset the adjuster and wind out lower rod end
•Tighten pinch bolt to 16Nm (5mm hex key + 7mm spanner)
•Lower car and re-measure
13mm MAX

Corner Weight 20
Adjustment:
•Make small changes in ride height and document each change
•To increase a given corner weight raise the ride height on that corner
•This will also increase weight on the diagonally opposite corner
•And reduce weight on the other two corners
•Always attempt to maintain ideal ride heights.
•E.g. rather than one full turn up make two smaller changes of
half turn up on one side, half turn down on other side
•Ensure left –right ride heights difference is as small as possible
•Front ride height more critical than rear
•For small changes we recommend changing rear ride heights to keep
the front aero platform level
Measurement:
•Lower car onto corner weight scales
•Bounce front and rear end simultaneously
•Let car settle
•Target:
•0-2kg difference corner weight across front axle
•50/50 weight distribution left –right with driver weight
•Same ride height across front axle
