I've used this unit now for some time and it's absolutely awesome. Highly recommended. The only downside is that you can only use it for one car at a time; if you want to use it for another car, you'll have to "unmarry" it from the previous car. Cobb also deliverys great support; they've added my model car within 24 hours with a new firmware update, as it didn't recognize my car out of the box or after the latest software update.

It holds many tunes created by Cobb and reflashing only takes a few minutes. Each tune is for specific recommended or mandatory upgrades. Of course it also features "Stage 1" tunes that require no hardware upgrade.

I did get quite some error codes after installing my tune, but i think it's due to faulty hardware (either my HPFP pump which was installed the day after i installed the Cobb module) and/or my turbo, which has been making strange noises (wastegate rattle). I do not see how it's linked to the Cobb map/tune, as i have gotten these codes after unmarrying the unit.

One map, the Stage 1+FMIC aggresive is not making more power than my Stage 1 LT Sport, which is strange. It's currently under investigation, i need to collect more data and send it to Cobb for further analysis.

Last but not least, the on board diagnostic info and the ability to save a run is critical for custom tuning the module, which is allowed with Cobb's software.

Alternatives would by the BMS unit (JB4), but i have no first hand experience with it.

Greetings,
Jeroen
