Device was fixed thanks to Bob and tune has been applied to the car.
The issue was - the software got corrupted during the update. The resolution was to remove app from the computer, install it again (flash drive) and update the app and the handheld device. This time around, the update process completed and the issue went away. Afterwards I was able to apply the tune to the car without any issue. Review of milvs coming up in few days after the car adapts to the tune. |

Lemme know how to get a set of MILVs.
Won't get to install them for a few months and I'll need to order the add-on tune for them from BPC but it'll be worth the wait, I think. At least it'll provide dyno info for the following config PI w/CAI and scoops RevMotorsports coupler WCRR bored TB 3IM Supersprint headers, coated and wrapped Supersprint secondary delete pipes Welded Burns merge to 3" thinwall 304SS exhaust Burns 4.5"x17" glass packed single stage race muffler just aft of merge Burns 6.25"x17" glass packed two stage race muffler/resonantor in stock muffler location Turndown tip

Mine arrived this week-thanks CM for your research and making this a reality.
VC gasket just removed and was not a jolly swell time. Went fine, no blunders but PITA. Gasket and hardware expected Monday. Have to have MILVS installed by then. Really excited. Full recipe BPC tune, soon.

For the people DIY tuning these, have you adjusted anything in the VE table? For the N55 we have one table listing rpm and you plug in a VE value. Stock is 93 across the board i think. Wondering if anyone has tested changing this table with MILVs.

There's no VE table on the N52 - well, there sort of is, but not really in the traditional sense. It's basically airflow over valve lift vs crankshaft position.
You need to alter the valvetronic maps of course, and maybe tweak the AFR target maps. I usually extend the airflow table mentioned above because by default it ends at 9.6mm of lift, but it's pretty linear so you can just scale that up to 11mm. The N55 probably uses VE because the MAP sensor is a much larger part of the engine control, where on the N52 it's assumed to be 100kpa most of the time and is more of a sanity check. |

Thank, only reason I ask is I don't think the currently available N55 table is the only one needed to be adjusted. Haven't found the angle vs valve lift table as seen with the N52. So wanted to look into other available tables that might need changing.
Currently I'm at the same boost and fuel consumption after milvs and the one table change. |

It is different from the MSx70 and MSx80 DMEs, but presumably the basic functions of valvetronic are similar. I think we have a Damos somewhere, I'll take a look. |

Unfortunately I'm pretty sure the table names are different between the N52 and N55. I have a document in german that lists all the functional table names and none of them match the N52 table names I've seen.

Got these bad boys today! Thanks again Marty for the fast shipping and smooth transaction. I'll send my returns back once these go in. Baseline dyno is booked for Wednesday. Aiming to install these this weekend if the weather warms up, along with the 3SIM and Bimmer Labs tune. Then get headers and do a final "after" dyno in May.
