How to confirm or verify Dinan Stage 2 Installation

[ashleysaturdays]

I had a hard time finding out this info, so I figured I would post it for anyone if they ever need it in the future.

Car needs to go to an Authorized Dinan Dealer.

Connect to the DME using the Dinan Software.

You will see 2 screens, ie screen will be split in half.

One side will show the BMW software info, the other will show the Dinan software info.

Confirm that the Dinan software install date is AFTER the BMW software install date.

It should also show the Dinan Part number for Stage 2 which is D900-31T

Additionally you will see the "Route Tune #" It should read 2PW...
The 2PW is followed by a bunch of other stuff but it is only the first three that matter.

You can ask your dealer to show you this after the install.

Easiest way to tell w/o going to the dealer is to confirm your peak boost is hitting about 12.6 under ideal conditions. Stock is 9.4

I had read somewhere that the rev limiter is also increased, but according to my conversation with Dinan this is not true. The tune runs out of steam before the rev limiter kicks in so it made no sense to increase it.

Hope this helps anyone who has the same question!
