EdC Posted December 18, 2012 Share Posted December 18, 2012 I received an email from my dealer requesting I bring my car in for a factory adjustment to the ECU, This is correct coolant temperature readout. Do you think this will affect the Cobb program installed on my ECU? Thanks, EdC Link to comment Share on other sites More sharing options...
urfsin Posted December 18, 2012 Share Posted December 18, 2012 Yes. Uninstall the Cobb then take it to the dealer...reinstall Cobb when you get home. Slide It Sideways Link to comment Share on other sites More sharing options...
MrTris Posted December 18, 2012 Share Posted December 18, 2012 @OP - Having the AP installed 'locks' the ECU from further writing/modification and technically voids your warranty. In order to properly fix the issue described in the TSB, your ECU needs to be writeable so that the dealer can reflash it. As was said, uninstall/un-marry your CobbAP, get the repairs done, and then reinstall the AP afterward. Link to comment Share on other sites More sharing options...
fishbone Posted December 18, 2012 Share Posted December 18, 2012 Wait what? So you take it in to the dealer, they reflash the ECU and then you wipe it and reflash it back to Cobb's tune? Unless I am misunderstanding what I am reading, you would essentially revert the dealer's changes. If you're worried about warranty issues, then proceed as outlined above. If not, sounds like a waste of time unless again, I misunderstood what is being done. Link to comment Share on other sites More sharing options...

It did however prevent me from using the AP afterwards since the AP was still married to the ECU which it no longer recognized due to the flash.

It may just update the coolant temp monitoring logic or it may be an entire new flash, including the tune. Either way, it's best to uninstall the AP (unless you have mods that would cause problems without the tune) let the dealer update, then re-flash with the AP. The AP *should* just update the "tune" and not touch the new dealer-updated coolant monitoring logic. Link to comment Share on other sites More sharing options...
