Hey guys just installed some HFC's on my 2008 and they work great etc, but the idle is just a little "surgey" and off.....

I reset the ecu etc... but i was wondering if anybody worked at a service department in a dealership that could reflash the ecu or something for me?

I don't want to void my warranty either with HFC's thats why I am asking in here

Thanks everyone! Hope to meet everyone soon!

 

The dealership won't be able to reflash your ECU. What exactly do you mean by surgey?

 

My idle surges.

For example from 700rpm to 800rpm and then back down..

It's not a huge surge as if I had a cam or anything but i can feel that the idle is a tad rougher than stock.

What can I do ?

 

How long have your HFC's been installed? After a reset the car should relearn and adapt after a day or two of driving.

 

For what it's worth my idle fluctuates all the time a few hundred RPM...although I'm highly modded.

 

I installed them on Saturday morning.

I did the ecu reset by disconnecting the negative on the battery for about 10mins.

That should do it right?

 

Disconnect the battery and step on your brakes to discharge any residual power.
