I personally would wait for a handheld OBII style plug in device that will let you easily remove/install the tune. At least that's my plan. I had a dinan tune on my N54 but it was a nightmare because I had to keep getting the car reflashed every time BMW came out with a CPU update which seemed to be at least 2 times a year. I know ESS made one for the E9x N55 models that was about $1000 and made about 40rwhp/60rwtq over stock....or about 45-50hp/70-75tq at the crank over stock. |

For the e9x cars those that tuned them had a Bavarian Tech (BavTech) code reader that was capable of not just reading the universal codes but BMW specific codes and was capable of clearing them. This is ABSOLUTELY CRITICAL because BMW developed "shadow codes" that are hidden and, if triggered, will tell the dealer that the car has been tuned. There was also a possibility that for cars with BMW Assist these codes were TRANSMITTED TO BMW before they could be cleared. I don't know if that's true or was ever resolved, but the shadow codes are FOR REAL.
For me this was all too much and I just decided against any non-factory tune altogether. Be careful before and after you tune. Just taking it out probably will not be enough. Too many people have had their warranties voided after removing the tune because they failed to clear the shadow codes. Have fun but be careful. The BMW warranty is worth its weight in gold, but its as fragile as an eggshell.

You guys make it such a big deal, install the JB and when you take it for service shut it off or leave it on. I have a 2009 335i face lift for almost 3 years and I have the dual cone intake jb3 then went to JB4 also have straight pipe, hid fog lights paint my top of the car black plus other shit. And I bring my car to any dealer for service no one has said shit to me. I'm getting my 2013 335 I M next week after this bitch Sandy came thru and everything is in hold.

Same thing i'm wondering about. Maybe the poster above had a dealership that didn't care about modified cars? Also, with the mods that you did including your painted roof, you had your car purchased right? No way a dealer would allow a painted roof.

If this whole BMW assist thing is true and it cant be disconnected, I think everyone is pretty much screwed as far as tuning goes, unless you are willing to give up your warranty. We all may be monopolized into BMW's PPK I also know there are a few members on here already with a JB in their cars, maybe they can chime in and tell us if they have BMW assist and how/if it does send shadow codes to BMW. Maybe this can be bypassed or tricked as well.

I talked to a service technician at BMW and straight up asked him if I brought a modded car to them would it be a big deal?
He basically said they do not care about mods when it comes to simple services like oil changes. So basically if you have your car tuned for a regular service, you should be cool. Just take it off and clear it before taking it for warranty related issues or engine related issues. I just ordered my JB4, so I am excited to be getting some extra HP out of it. |
