    Installation Manual

    The 123\BMW-4-R-V is designed for M10 engines, in the BMW :

    – 1600, 1602, 1602Ti
    – 1800, 1800Ti, 1802

    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.

      If you're thinking about getting this, just do it...

      Posted by Eric on Jan 11th 2025

      This was so simple to install I thought I just got luck so I took it out and reinstalled it again and it was bang on. Excellent upgrade for your older vehicle. I love it.

      Distributor for 2002

      Posted by Rick on Dec 17th 2023

      I installed this along with a Weber carburetor. Between them they transformed the vehicle from anemic to strong. Highly recommended

      BMW 2002 distributor

      Posted by Chris Scott on Jan 4th 2021

      Everything that this product claims, it delivers. Easier starts, smoother running, better high rpm ability (doesnt break-up like points at high rpm). The only reason it didnt get 5 stars is because Ive only had it a short time and I dont know how reliable it will be. I will come back in a few years and report on that aspect!

      A smoother engine

      Posted by Marcel on Aug 23rd 2017

      I drove a few km so far, but since it was installed in my '73 BMW 2002, the engine runs smoother and cold starts are easier.

      Nice product and easy to install.

      Posted by Eric on Jan 25th 2017

      Installed and timed the switch version in my '75 BMW 2002 the other day replacing a fairly new IE full centrifugal advance unit that was in the car when purchased a few months ago. I'm currently evaluating advance curve 2 and notice the motor seems to run and accelerate better. As time allows I will try different advance curves but would like to see plots of the16 different advance curves. More information on these curves would be very helpful. Instructions were adequate to install the unit. The rotor seems to not fit as positively as I would have hoped but so far it has not been a problem. No oil leaks using the single rubber "O" ring seal included but do wonder if the second indent on the shaft higher up may also be used as a second O ring location for insurance.
