does bmw have a clear flood mode?

[b*saint]

I know most modern cars do. If so is it the same technique (hold pedal to the floor?)

on e30s? not to my knowledge. pull the relay and crank the motor over instead.

never been sure why this would be needed on an EFI car though. bad CLT sensor? leaky FPR/Injector?

No they don't. I tried it on my 325.. It started up and just hit the limiter lol.
