DC to DC needs convertor?

OIL: Shell TMO synthetic 5W40

5W40? I saw use 10W60 only from a pic..

Ps: About the ECU , do you think M POWER using "Motech" too ?

the detail for the formula 1 E. controller ...

ps: and shock to know more about The F1 have no Flywheel (only the side gear for the start up) ? any expert can tell the theory about it ? Maybe I wrong .... I love to discover technical thing
