Is this true about running in new engine?

[Whyeme]

Got this quote from someone from sgkiaclub:

 

'The initial run-in is to let the ECU get use to the owner driving pattern....so if u drive like ku ku during run in, yr ride will perform like ku ku too...'

 

True? experts pls advise

thks

 

[Byond]

i am not an expert..but i don think so....

how ku ku is ku ku?

can define?

maybe that is for those ku ku owner??? NOT TURE dun apply to all car.

 

I know BMW dun seem to need run in, on the other hand, on Honda Car owner's manual it say 1st 300km no hard braking and 1st 1000km no hard driving after 1000km?? do whatever you like Open V-TEC lor

[Watwheels]

I didn't know ECU nowadays got built-in AI (artificial intelligence) or Fuzzy Logic like a washing machine.

 

I wonder which ku ku came up with the theory....

[Macrosszero]

People who drive your brand new car on and off the boat, between the dealer's yard to the various outfitters eg. leather seats, window film, audio, don't give a flying f*** about running in. They drive like ku ku also. Then how?

[Hermitage]

Ain't no expert but I really don't think so mate. Most modern cars are more intelligent than we think and won't get 'stuck' in one mode just because you've been driving it like that all along! How to buy 2nd hand like that?!? It should be able to 'learn' each drivers' presonal habits & preferences and set itself as optimally as the stock ECU will allow.

thks bros

 

enuff said.

the guy who made that ku ku remark is the kuku one

[Jonbummer]

if the ECU can get use to a driving pattern i'm quite sure it can also learn or relearn

a new pattern

 

unless the ECU is designed to learn only up to 300km of driving

which is of cos very unlikely..

 

just my thots

[Tanly]

That someone knows sh1t abt cars.Most prob he's a 1st or 2nd time car owner trying to act smart.Run in is to make sure all engine components well seated and to prevent any leftover manufacturing waste bits from doing damage to the engine internals.But alas most of our new cars already 'run-in' by ppl handling the cars.

Disconnect batt for 5 mins, then re-connect.

 

ECU "may" forget your fuzzy logic driving pattern to optimise fuel economy.

 

Whack hard -> ECU thinks you like power over FC.

[Espire]

watz so important of letting the ECU get used to the driver patterns...

 

jus remove the fuse to it.. it resets by itself.. back to factory state... tada....

[Vblaster_w211]

For new engines, the run in is to ensure good sealing of pistons rings for compression. Run the engines by driving normally/aggressively, and bring the throttle to near redline. Run in through all rev range. We have a short time before it's set. Never drive new engines gingerly. The sealing will be less than perfect and engine will never be as powerful as it could be.

 

The ECU will learn our driving. But it's no big deal, just a reset and the ECU will clear its memory and relearn.

 

 

 

[Kyojin]

he is partly right but inaccurate.

 

the running in process is to ensure that the metal parts of the engine are "gently" worn in. but not for the ECU to learn your driving pattern.

 

that said, the ECU does "learn", but not your driving pattern. it learns when to advance/retard timing and stores it in its memory so that when it detects that same parameters (RPM vs engine load/vacuum) it will correct the timing automatically. this is why when you reset your ECU by removing your battery, initial driving response might feel different from before the reset. this gives the impression that the car is actually learning your driving pattern. it's not as smart as fuzzy logic.

thks for the advice. does all new car manuals (the instruction booklet) teach this method too?

[Kyojin]

there are two schools of thought on how to run in the engine - either the gentle way or the aggressive way

 

i personally am more comfortable with the gentle way and most owner's manuals recommend this way too.

[Vblaster_w211]

The aggressive way is proven and adopted by garages and tuners, locally and overseas.

 

Mercedes also recommends stressing their new engines.

it's not proven and you make it sound like every respectable tuner does it. that's simply not true. rather, there are just two camps and it depends on which you want to believe.

 

manufacturers, including MB (AMG too) and Porsche, recommend the gentle method. the break-in period not only allows the engine to break-in, the gears as well and for the brakes to bed-in.

There are 2 camps. And one right answer. And we don't mean driving hard beyond redline. Vary the rpm, and push below redline by 1-2K or so.

 

Mercedes does not endorse baby throttling new engines.
