Elan Sprint 123 Bluetooth Distributor for Weber engine
Posted: Fri Jun 26, 2020 8:33 pm
Has anyone got a good ignition map they could share? The one 123 suggest is hopeless.
Thanks in advance

I could have spent approx £240 and sent my Distributor for a complete overhaul to “Distributor Doctor”, but concluded to keep my original and invest in one from 123 Ignition at £399 + £12 postage.
I purchased the Bluetooth model 123/tune +4-A-V-F, along with a Pertronix Flame Thrower 1.5 Ohm coil and Silicon/carbon leads.
Had no problems with the installation and setting static to 10 degrees BTDC that was straight forward.
The fun was selecting which advance curve to use!!
My engine has cams with single groove so a “C” type cam and so my first curve was from Miles Wilkins book, for the above cam with Webber carbs.
1) Settings for “C” cam
The result was terrible, right up to 4000 RPM. This being my current max for running in the engine. I was surprised by this result.
I then tried the built in default, which was certainly better, but not correct.
2) Settings: - Default.
Finally I found this thread and I tried those listed by “nmauduit”
Wow, what a difference, Thank you “nmauduit” for your contribution.
3) Settings “nmauduit”
I can now “fine tune” this curve by driving the car while the passenger presses the “Tune” button. Each press will reduce or increase the advance curve in increments of 1 degree to see if there is any improvement, on any of the curve points, on what is already a good running engine.
4) Dashboard with Tune button.

Are the advance numbers displayed on the app just distributor advance (in crankshaft degrees), or does it also include static?
