Just installed ECIS intake on my 04 330CI. Car feels slower at low end, when i get close to 5k it starts to pull fast. Should I reset the ECU? Get a Dinan Chip? Thanks

Ecis Cai

Your car may need a week or two to adjust to the new air ratio. Give it a little time to settle and change settings before making your final judgement :)
:werd:, give it a little time to make the needed adjustments and once it does you'll definately know :woot:

I would reset the ECU, then wait a couple days after hard driving to see the final results ... :)

I had a ECIS before... Make sure you didn't put the K&N filter too far onto the metal pipe, this will block lots of air. I did this on accident the first time I installed it, and I actually got a SES light, due to the restricted air flow.

And as the other poeple said, you need to drive around 150+ miles for the ECU to fully adapt to the increased airflow.

I reset the ECU, left the negative battery terminal unplugged overnight and when I started it up this morning i gave it some guess and there was TONS of hesitation and it died. Kept doing the same off and on. Havent had the chnace to drive it yet though. Is that normal for that to happy?

Could be....

^^^ Sounds like you might have screwed up your "MAF" during your install of the CAI. Got to be super gentle when affixing it to your heat shield and or inlet tube :yikes: Do a quick Search re: MAF sensor;signs of hesitation, stalling, loss of power :idea:

Yes, it does sound like a case of a faulty MAF ...

So how do you do the 10 sec key thing? Please don't tell to search.

FYI - that does not reset the DME. The only way to really reset the DME is with the dealer's GT1 service computer.

If any mod you do requires adaptation, that will occur all by itself... just drive the car and let it happen.

Place your key in the ignition and turn it to position 1 for exactly 10 seconds. Then turn the key back to the off position for exactly 10 seconds again. After the 10 seconds is up, immediately turn your car on.

If you mess up, you can't do it again for something like another 10-15 minutes.

That's the silly "throttle adaptation reset" procedure. That doesn't "reset" the computer. If there is adaptation going on then do as Rob stated, let it ADAPT.

To the guy asking, maybe you didn't get things on tightly enough and you've got a leak. Make sure your connections are nice and secure, don't overtighten as that can cause leaks as well.

Yea, I know... was merely throwing out an idea. Not sure why it's "silly" though.

Might as well let it adapt from ground zero with the intake on though.

Nothing personal. I wasn't saying that your comment was silly, just the procedure.
If you want to know why I think the "reset" is silly, it's because the throttle ADAPTATION does not need a reset. The reason is in the name.
If it's "adapting" then you do not need to reset it. Why?
Because it will ADAPT to your driving. :)

Fun with terminology.
