This procedure is recommended in the Fiesta owners manual. It says the car should be raced above 3000 RPM for at least 30 seconds once a week. It doesn't do anything to the ECU. It clears the exhaust soot and makes the car smoother to drive.

GTO is right. A car that has never been high revved in its life will feel sluggish initially. Take the same car on a spirited highway run, and she will rev much more freely after that.

Hahahaha.... I am a sport alright. Just difficult to find roads for such spirited driving here in Mumbai and when I do, get pulled up by the law for speeding

When I'm clearing out whatever causes that black smoke, I rev hard in 2nd. High revs, but no excessive speed!

This is not a substitute for an extended period of highway driving, though.

Default Works for alto

I've been doing this since two months ever since I got a hard clutch to minimize gear changes. The clutch is still the same though the engine feels a little sprightly now. I just redlined her(or so I think) at a traffic signal by going over 30 in first much to the show of scared scooterists. IMO any engine should be allowed to fully flex all its muscles during its lifetime. In a sedatley run car, these muscles atrophy and give a hollow driving experience.

Mine definitely is better than my neighbour's now. Verified by him & me.

This is no sham as I initially presumed. It WORKS.

Applicable only to petrol or what?

Touched 70kmph in 1st gear once and felt guilty about it. This thread has brought some peace to me. Sigh.

OT: Mine is a VDI.

I guess you should go on feeling guilty about that!

No: mine's a diesel. I'd be quite worried if I got black smoke from a young petrol engine.

Saw the owner's manual. It said max speed in 1st should not exceed 45kmph (or in the whereabouts). My heart sank and to top it all, she had done 1300 on the odo when I did it.

A moment of passion and life long regret

My explanation , when you go with high rpm in low gears say 3d gear the fuel injectors nozzles open fully. This helps in spraying fuel fully & cleaning the fuel line. Any carbon deposits on the injectors will burn away. At the same time piston rings become free of any friction. Stand still revving will damage engine. You can also try getting injectors cleaned and recalibrated .
