N55 DPFIX!! - Page 2 - BMW 3-Series (E90 E92) Forum

Mike, does this play with air/fuel ratios very much? I've read some N54 guys have needed to remove theirs because over time their afr gets out of sync.

Hey guys, I'm a little confused. What does this DP fix exactly do other than keep the DME happy so I don't get a code cuz of the catless dp? Will it change my fuel ratios to keep the car running normal?
On the BMS website it says you don't need this is you have a JB4. Well I have a JB4, but I keep it on map 0 most of the time. So I think buying the DP Fix would be good in my case?

Hey guys,

Some bad news on this project. The downpipe fix logic implemented is working well for the N20 motor and it was expected to also work for the N55, since they use the same O2 sensors and connectors, but during testing that has proven not to be the case. The design is not compatible with the N55 DME. So a new product will need to be redesigned for the N55 downpipe fix. Unfortunately BMS does not have an ETA for doing this so as of now this project is on ice. Sorry for getting everyone's hopes up.
