I have an M Tech unit which I bought a few years back but didn't get round to fitting until now but I've lost the set up instructions. Does anyone know what the various positions relate to?

Also any feedback on them would be appreciated.

Cheers

here you go.............

Chisel Speed Advance / Retard unit

The values are dependant on the tolerance of the rotor winding, and as such will vary from unit to unit.

With the static set at 25 degrees advance then at 8000 RPM the advance would be:

Unit Setting Advance
0 21.
1 20.5
2 20
3 19.4
4 18.5
5 17.9
6 17.3
7 16.7
8 15.5
9 15
A 14.3
B 13.8
C 12.8
D 12.3
E 11.6
F 11.1

Many thanks Mick, I didn't realize (forgot) it was marketed by Chiselspeed and I just found your chart and some more information on their website and also MB have some additional info BUT it seems a bit confusing to say the least :? Chiselspeed say it retards and MB says it advances :? I reckin I'll just have a play with it and see what it does, at least it's easy to adjust timings with the external pickup 8-)
