123 Distributor
Discussion
Hi guys.
Just fitted the Bluetooth version of the 123 Distributor to my car. I fitted this at TDC so all the advanced is done by the 123. The curve I’m using is this as downloaded from the 123 website. I know I need to to get a RR session booked and will do after I have fitted the upgraded Bosch injectors. In the meantime your thoughts would be much appreciated.

The Rover V8 owners and enthusiasts group on Facebook will probably have an answer for this as I know a lot have them fitted.
It probably needs a bit more at idle I would say, maybe 12 degrees.
Let me know if your not part of it or cant join for a while, I can ask the question for you.

You can join the group quite readily.
Hopefully Steve Sprint will be along soon with his experience of the 123.
Without having a 123, I would say 8 degrees at idle is too low - but this is based on what I know of the mechanical dizzy.
8 degrees is setting it like the ported system, so might be necessary for MOT emissions, but not ideal for the engine.
My mechanical dizzy is set to 8 degrees without vacuum advance.
The advance module is connected to a full manifold vacuum connection, except for MOT day when it goes back to ported on top of the throttle body.
With full vacuum, the advance sits at 18-20 degrees at idle.
The engine picks up from idle better with that level of advance.
It obviously has a limit due to being mechanical as the engine spins faster, but should be getting up around 38 degrees I believe when reaching 4k rpm.
If you have the ability to play with that, I'd certainly look at it!
The thread on 'god damn shunt' goes into this detail, and is quite informative when StuVT starts experimenting on his car.
