Software version E89x-10-06-502 question

My car is currently equipped with software version E89x-10-06-502. Is this version old enough where I would see some HP gains if I updated?

Thanks.

PM Tom@EAS.
He updated multiple cars and backed it up with Dyno to prove it so he can tell you what you need !

Good Luck !

Scheduled an appt at Sterling BMW for the update. They were the cheapest around at $155. Ill let you guys know if I feel any difference between the new and old firmwares.

It appears the latest firmware if you go by date code is ISTA/P;2.48.0;E89X-12-11-507? I also see one referred to as 2.48.2 but the date code is E89X-12-07-508. I'm a bit confused because the 2nd one has an earlier date code but the last three numbers and the "2.48.2" seem to indicate it is a newer firmware?

Beware of Sterling. Not the brightest of techs. Just had a customer's car there and they were very unsatisfied and will not be using them again. I suggest contacting Marco at McKenna Performance if you want a dealer to do it.

Yeah, it seems all of the dealers around here are terrible. I have been going to Sterling for awhile but after having some problems with them during my last visit (they replaced my battery and charged me $500 without even giving me a quote for the work and I had explicitly told them beforehand NOT to change the battery unless it was covered under warranty) I decided to try Crevier.

Upon getting my car back from Crevier yesterday I discovered they put a small gouge in the intake manifold while changing the plugs and also scratched the hell out of the intake pipe while reinstalling it (looks like they were prying on it pretty hard trying to get it to slip over the airbox).

My steering wheel also had some nice abrasion marks (thankfully cleaned off with some elbow grease) from what looks like someone driving the car while wearing a ring and to top it off a big brown mark on the lower part of the door where someone kicked it while wearing brown soled shoes (brown mark came off but looks like theres some permanent marring). There was also a mystery scratch on the rear bumper I just noticed today but who knows if that happened while at the dealer. Also, they filled my tires with air pressures varying randomly between 31 and 37 PSI.

Different integration levels can have the same date code

Take a look at the 231E update thread, I think I posted the integration levels there awhile back. Once I get back in town I can give you a more definitive answer
