Hard reset improves performance?

I did a hard reset yesterday and afterwards the car seemed to have slightly better pickup and acceleration.
Is it just me? Confused

On many cars, a hard reset will cause the ECU learn your driving style so, a hard reset and drive like you stole it if you want more performance. Hard reset and drive like a nun and you'll get good economy. Past: FL2 TD4 HSE Auto

Yes I agree. On my FL1's I used to reset the 'driver learning' program after each time my ................. (now ex-) wife had driven it !!

Disconnect battery and hold leads together for ten seconds or so then leave disconnected for 20 mins (well thats what I did!)

It's something you may need due to old age.

You can get pills for it.

A "hard rest" can be a risk to modern vehicles with electronics. It's a myth from many years ago… the theory of disconnecting the battery leads then shorting them together to kill any power left and reset the car. It's no different to disconnecting the battery and allowing the car to use up any electricity still in it, which has the same effect but without the risk.

Shorting the disconnected battery leads together is a risk because in induces a sudden current flow. Hence the spark. Electronics does like sudden large currents discharged from itself. This can damage electronics. If you want to do this sort of thing yer would be better to disconnect the battery and just leave it disconnected for a bit. In truth the vehicle will lose power within seconds but if yer really concerned then leave the lights on and watch the power remaining in the vehicle disappear quicker. Hippo's videos - Honorary Tratterer

Is the point of leaving it for a suitable length of time not to allow any capacitors to discharge? Happy to be corrected, but I don’t understand how leaving the lights on would have any effect on anything that was not part of the lighting circuit? Confused 2005 D3 2.7 Auto

Yes, leaving for a bit of time to allow residual volt's in cap's to be used up and therefore disappear.

Some peeps are convinced cars can stay alive for some time after battery disconnection so leaving the lights on uses up any volts which may be present in the main power feed rails. Not really needed. When electronics is fed from the main +12 volt rail and has its own power supply circuit which converts to other volt ranges like +5 or +3.3vdc then these "inner" circuits can only dissipate the electrical energy stored in them by having their main power feed disconnected, then left like that for a bit. They then eat up any power within themselves and stop. Hippo's videos - Honorary Tratterer

we use a hard reset, to reset immobilizers on various vehicles,we disconnect leads and place a 12v light between them.using a volt meter between leads you can see milli volts gradually reduce,up tp 30 mins before it reads very near nought millivolts,then the immobilizer is usually reset.applys to ecu,and other body control modules.

That's a safe way to do it as your draining the power slowly. The computers would have fallen asleep long before yer meter can only count mV. Hippo's videos - Honorary Tratterer

Does anything need rest afterwards, apart from clock? I've read about window motors needing re calibrated? Landrover - turning owners into mechanics since 1948
