Not saying that warming up by driving gently (low loads, low/mid rpm) isn't the best way to warm it up. It's what i do every day!

IMO, if you wanna warm the car up before you drive it in the winter, that's fine.

the point is the ECU of 30 years ago were smart enough to adjust to ambient conditions, i doubt they have degraded since.

production cars were designed with the idiot driver in mind, turn key and go.


worth while to note i had a chance to talk to an owner of a Radical SR8, and boy does that thing have a complicated start procedure.

water/anti-freeze Starting Procedure
1.

Always start the engine with a laptop connected to the ECU so that all engine parameters canbe monitored during warm-up.2.

Check oil is visible in oil tank (aluminium casting between engine and gearbox). Check waterlevel, turn on electric water pump (if fitted) to check that the system is free of air (2
nd
switchfrom right, next to ignition switch). Actual oil level does not matter at this point, because anamount of oil has drained back into the engine
–
this returns to the tank when the engine isstarted.3.

Crank engine to get oil pressure with ignition coils disconnected.4.

Connect coils and turn ignition on. Start engine with no throttle, let engine idle atapproximately 2,000-3,000rpm. Check oil pressure is at 60psi minimum.5.

When engine water temperature reaches 50°C, rev engine several times to over 6,000rpmand turn off.6.

Immediately check oil level, it must be 250mm ± 10mm from the top of the filler neck
Restarting Procedure
1.

Ideally, the engine is started 45 minutes prior to going on track. Turn off when the watertemp. reaches 85°C and allow heat to soak into the engine. Restart 10 minutes before goingon track and get the temperature to 75°C.2.

The electric water pump is only used in the pits (if fitted). On track it is not necessary. Useelectric pump when the engine has stopped, to prevent engine from heat-soaking whilststationary. If no electric water pump is fitted, the engine must not be allowed to overheatwhilst stationary.3.

The oil level should be checked every hour of running and it should be topped up to the levelindicated above.
Running the Engine
Do not run the engine under load if:-a)

oil temperature is below 60°Cb)

oil temperature is above 120°Cc)

water temperature is below 60°Cd)

water temperature is above 100°Ce)

oil pressure when up to temperature at 4,000rpm is under 50psi.The oil pressure when the engine is started from cold should run at 90psi at 4,000rpm. When up totemperature the oil pressure should read 60psi at 4,000rpm
