Pretty sure the 8 function Imperium is the wrong type of function output for the Class 22 and it needs the original Imperium 1 (6 function).

I'm slightly surprised at them offering sound fitted while staying with the 8pin socket. Be interesting to see what speakers are used.

Bachmann's own product page tells you its an MX634C https://www.Bachmann.co.uk/product/class-90-dcc-loco-decoder-with-servo-motor-operation-and-brake-function/36-569a

Factory sound will be a Loksound 5 DCC.

Not convinced an ESU decoder needs 14V+ to work otherwise they'd never work in DC mode. The whole thing about the stayalives needing 14V to work is another of these ESU things that doesn't seem to be documented anywhere in ESU's own manual.

No real risk other than things randomly not working correctly. Unless you have pretty much hundreds of devices connected to your home network at once, I wouldn't give it a second thought. For what its worth, the router that came with my Z21 has never left the box. The Z21 gets plugged into my network by ethernet whenever I'm using it. I could change the IP settings but there physically isn't enough networkable devices in the house to make the router get to the stage of trying to assign .111 to anything...

Sadly in my experience most smaller model shops only give extremely basic receipts that have the amount of money spent listed but no details of any use on what the money was spent on.

The Lokprogrammer's method of reading an ESU decoder doesn't normally care about a motor being present.

One of these: https://www.esu.eu/en/products/former-products/lokpilot-standard/ Think a Lokpilot v1 is something else .

Fairly sure thats the Lokpilot Standard v1.0 version so miles better than the Soundtraxx version but not quite as good as a full fat Lokpilot 5. Not sure if they have it but have you tried the CV54 autotune? (Place loco on a decent bit of straight track, set CV54 to 0 and activate F1)?

Looking at the sound function list posted earlier in the thread I can't help think 2 separate functions just for the bell on Evening Star seems a tad excessive 🤔

It should fit fine, like most modern Dapol diesels there's plenty of space because of the speaker space. You might need to use a smaller speaker to leave space for the stayalive. I'd be questioning why your 22 needs a stay alive though, 4 axle twin bogie diesel usually means at least one bogie is safely off the pointwork at any given time.

I'd be trying disabling DC running in CV29 based on getting one of them to respond for a bit. I also recommend investing in a decoder tester (Both Zimo and ESU do one or if you are really cheap considering its basically a clone of the ESU one, LaisDCC do them as well). Very handy to test decoders out of locos. Unlikely to matter but could be a similar issue, the new tooling Class 47 I had (got rid cause I really need to stop getting big huge locos on a 6x4 roundy layout) almost always refused to program via my Lokprogrammer but if the decoder was removed and programmed outside of the loco it was fine. One thing just dawned me, what is the Bachmann product code of your decoders? The B versions are the new MN decoders and my honest opinion of the Zimo MS/MN series just now is the firmware is extremely half baked compared with the MX and they just seem much more flakey.

What vintage is the decoder? Annoyingly Bachmann used the same product code for 2 completely different 21pin decoders (1 was a Soundtraxx, the other an ESU LokPilot Standard 1.0). Bachmann tender locos quite often don't have tender pickups so a stay alive is worth considering.

Nope, the Baby Deltic models are 8pin and predate independant lights. Would require rewiring to have separate control of the tail lights although it might be possible to just unplug them.
