BMW 3-Series (E90 E92) Forum - View Single Post - Update for Engine Control Module. Should I Update?

WhiteFury · 10-11-2013, 05:53 PM

I just got my DME updated at the dealership, and my exhaust got quieter. Yesterday I had my secondary cats cut off and I love the way it sounds, now it sounds like crap.

I do I fix this, or get rid of this update?

Also idle isn't as smooth and my sputter has returned.

I am providing pictures of my update to see what software version I have and if you guys can tell me anything about it.

ISTA/P version - 50.4.002

Integration level - E89X-13-07-503
