Approximately 95 miles on the tune so far. I double checked my o2 sensor connections and have thoroughly checked for exhaust leaks. Unpluged the precat o2 (which forces the ecu into open loop mode) and it idles fine. Reconnect the sensors and the problems back. |

Nope I've tried it with the air-con on and off. No difference.
I'm thinking that maybe the car doesn't like either the reduced EGTs or the reduced pressure at the o2 sensors. Then again maybe not. The Bosch LSUs BMW used for the precats have some of the best heaters and have a pretty wide operating range as far as pressure and temperature. |

I may have resolved my idle problem! Salman over at evolve suggested that it may just take more time idling for the idle to adapt, and suggested that I let the car idle for at least 20 minutes. After a couple of long idling sessions the fluctuations are only occassional. It will idle fine for a few minutes and fluctuate and shake for 20 seconds and then go back to normal. Before, they were constant. Hopefully my idle will continue to improve. |

It did this for about a week and a half and gradually got better after a few 20to 30 minute sessions of idling the last few days. This evening the problem was almost completely gone! I guess idle adaptation takes a while! |

Wow our ecu suck, it took me 25-50 miles in my last car to adapte and log before I could revise my tune again.

The instructions with the Evolve-R state that it generally takes 15 miles for most gains to be realized but that it may be take a couple tanks of gas for full adaptation to occur.
In my case the car performed great right from the moment I installed the tune, with and felt like it had great gains. The exception was at idle speed. In my case I had to spend a lot of time actually idling to get the idle smoothed out. Maybe it's due to the fact that I did do quite a bit of WOT redline and near redline pulls immediatly after the tune I'm happy to say that my car now idles perfectly. I'm sure adaptation varies greatly based on driving style and modifications. |
