Hi. should i wait my car to warm up 2 or 3 bars before i go. or should i just wait for the 'sound' to come before i go? (the sound that car makes like a blow-off valve)

And i m still confused about the ecu reseting . i got new stuff for my car (intake , header , exhaust with test pipe) do i have to reset my ecu? or just let it learn? if i let the ecu learn . whats the technique of that? like driving the car hard for 1-2 hours ? or letting it learn in a longer time like a month or so.



thanks

No. I think even your owner's manual tells you not to warm up before driving. Start it up, wait a few seconds for the idle to stabilize and start driving it easy. It'll warm up much better and more efficiently while being driven.

What the heck are you talking about?

Don't reset your ECU just because you put new stuff on the car. It'll learn on its own in time (several driving cycles). If you reset the thing, it'll go back to its default settings and have to learn everything all over again. Unless you have a problem with the car that you are trying to resolve, resetting the ECU is not necessary.

 

the sound he's talking about might be the whistle of the emissions air pump...?

 

Well, the air pump doesn't sound like a BOV to me and with the noises from the engine, exhaust and stereo, you shouldn't hear anything.
And no, you don't wait for the airpump to stop. Sometimes, it can run for 1/2 a minute and other times, it can run for several minutes.

 

the fuelpump is what your hearing probally

 

Duwhat?

 

Fuel pump is a continuous thing. Most of the time, it's silent and can barely be heard. Every now and then, it gets a bit louder and sounds like the distant whine of a jet engine. It doesn't sound like a BOV, either.

 

The airpump is probably what he is talking about. The fuelpump doesn't make any whistling noise (or none that I hear anyway)

 

I let my car idle for 2-5 minutes at times before i drive. This a no no???

 

I always let it warm up until I get 3 bars. The noise always goes off by the time I reached the 3 bars. Its being two years and my car has never burn a drop of oil and runs smooth and strong as a champ. I don't think that has nothing to do with it but I always like to think so.
