the siemens ECU is stupid bcoz it is a self-learning ECU.
if u REMBAT the car everyday, then ur car will be quite responsive.
but if u suddenly drive in a mild attitude, then it's hard to push the car to the max bcoz the ECU has learned the current driving behaviour.

that's y got some people claimed they can go up to 230kmh and some claimed can only go to 200.

more over, it is a mass production car fixed by mechanics with 'proton attitude', so some cars is quite perfect and some is rubbish.

response can affect top speed eh??? i thought only ratio and horsepower???

also, self-learning = stupid??? i thought intelligent???

but yeah, making things more and more intelligent, it can also become more and more stupid... laugh.gif

I dont remember ECU control the top speed... doesn't matter how I drive, still the same...

there's a shortcut to the good response when you need'em, and relaxing drive when you need'em... reset the ecu thumbup.gif

owh yeah? how to reset the ecu?
so there will be a big waste la to those people who bought piggyback like dastek unichip and haltech interceptor just to make the car more responsive and powerful.

you have to differentiate the reason of installing piggyback and default ECU limitation...

piggyback is not to adjust the response only...

what i'm saying here is, force the ECU to relearn everything from scratch... everytime ECU lost his power supply, he'll lost his memory and have to relearn by himself... since it seems to be ECU learning has become a big issue like it's the world's end to you, i told you a shortcut for the ECU to unlearn everything so it'll response by default setting and relearn your driving style...

dont tell me ECU have permanent learning memory... and i'm 100% confident i am not wrong here as my engine always acting differently after this "ECU reset" and it's the same characteristic all over again...

piggyback is another whole issue... not only to improve the response, but a lot more tweaking of input to the ECU and output of the ECU so the engine have different response where ECU limited the performance of the engine before...

so, if your engine is topped at 180km/h by default, no matter what driving style you have it'll only go for 180, never 200... just how fast it gets there... when you got a piggyback helping you, you might go over the limit... that's all...

mrl, i hope u don't mean reset ECU by disconect the battery...

i think there's a fuse connecting to the ECU??? just take out the fuse for a while and plug it back... you're good to go...

but unfortunately yeah, i always disconnect the battery though... because usually i reset my ECU in conjunction with my radio hanging up... and till now, i still cannot find the fuse connecting to the HU... lazy to find some more... sweat.gif

lol dat day i disconnect d battery to install my vs meaning to say i had reset-ed my ECU indirectly d lor? sweat.gif

yes... it'll have to re-learn your driving style all over again...

and guys, i'm not talking about resetting as in remapping or reflash the ECU with default firmware... i'm saying the ECU just have to relearn your driving style all over again... so, if you drive slow and having fuel economy response and it's a big issue to let the ECU learn for a while you want to drive fast, just force the ECU to learn all over again...
