APR Question

[Whubbsie]

My understanding is that the reason for not babying the car from new isn't because of the ecu adapting, but for the piston rings to bed in.

See: http://www.mototuneusa.com/break_in_secrets.htm

I would say that the reason why APR would be saying that it takes a couple of days to acheive full power after chipping would be that the ECU would run timing and fuel mixtures pretty conservatively and would slowly get more aggressive with timings until the knock sensor kicks in. Its the same system that allows our engines to survive but be slower if we put lower octane fuel in.

thats what i ment... but put much much better.... and with links

I think running a car hard , and gently running it in both have their own implications , run it too hard you will have crankcase breathing issues , run it too soft good chance you can glaze the bores . Just vary revs / load and you will be right . I also dont think that driving it gently then hard will really have implications at all .

And the adaption on a Polo should be much quicker than that , its the mk5 gti that seems to take forever to adapt !

Ive actually hear that its ok to rev a new engine hard, encouraged in fact, but dont load it up and to use the gearbox - probably just another opinion from another mechanic who thinks he has a better opinion LOL
