The gear on the BMW 4-R-(V) causes the ignition to turn Clockwise.
If you have a newer type M10 engine (e.g. in the BMW E21 after 1978) a gear that turns Counter-Clockwise (CCW) is needed, as well as a distributor to which it fits.
You need to transfer this gear from the old ignition.
The 123\Switch units are easy to install. Preprogrammed original manufacturer ignition curves.
By selecting 1 of 16 available advance curves, this electronic distributor is suitable for many engines
Please take a look in the advance curve table of the specific unit for available advance curves.
