Programming your ideal advance curve? The 123/TUNE ignition enables you to do so. Just using a (shielded) USB cable and notebook. So if you want to tune your engine or have an engine that does not have a standard distributor available... the 123/TUNE can help you out. You can easily setup the 123/TUNE to fulfill even the most demanding requirements.

The "BMW" model will replace as used in combination with BMW M10 engines that don't need a trigger pulse for injection. Please check dimensions and installation manual before ordering.

123/TUNE the USB programmable electronic 123ignition

Programming your ideal advance curve? The 123/TUNE ignition enables you to do so. Just using a (shielded) USB cable and notebook. So if you want to tune your engine or have an engine that does not have a standard distributor available... the 123/TUNE can help you out. You can easily setup the 123/TUNE to fulfill even the most demanding requirements.

The unit offers two sets of curves that can be selected by placing power on the yellow wire from the 123/TUNE. By using this function you will be able to switch between two pre-programmed curves without having to use a computer. Particularly apt when you are (also) driving on LPG.

Model "BMW"

The "BMW" model replaces distributors used in BMW M10 engines that don't need a trigger pulse for injection (please check dimensions before ordering).

Features of the 123/TUNE-4-R-V-BMW

- For positive and negative grounded cars
- Variable dwell constant current, fully autom. (autodetect)
- Coil current protection time-out after 1 second (autodetect)

- Two centrifugal advance curves (500 to 8000 rpm)
- Two vacuum-advance and boost-retard curves (0 to 200 kPa or -30 inHg to +15 psi) with MAP-start fields
- Two rev. limiters (advanced random spark stealing)
- Real-time tuning under keyboard-control (ideal for working on a rolling road)
- Rpm-stopwatch (ideal for tuning using the road itself as a rolling road)
- Luxurious import-from-file and export-to-file (curves can easily be exchanged over the internet).

While using the software an electronic 'dashboard' will show you

- Temperature gauge (selectable in degrees Celsius or Fahrenheit)
- Manifold pressure (selectable in Bar or inches Hg/Psi)
- Tachometer (0 to 8000 rpm crankshaft)

- Total-advance gauge (in degrees crankshaft)

Before you order, please note about this 123/TUNE

Please note: The gear wheel of the TUNE 4-R-V-BMW ensures that the ignition rotates 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 wheel from the old ignition and fits on our following distributor: see 123/TUNE+ 4-R-V-BMW CCW.

We strongly advise you to check the dimensions of the 123/TUNE with the original distributor cap AND to carefully read the installation manual before you order! In the installation manual you'll find more information and a few examples with a step by step explanation on how to install and program the 123/TUNE.

You can download the latest version of the 123/TUNE software here: www.123ignition.nl.

The minimum system requirements for the 123-tune software are:
• MS Windows XP
• 1 gigahertz (GHz) processor
• 256 megabytes (MB) RAM
• Free (powered!) USB port
• Shielded USB cable with mini-B plug (male) – also available in our webshop

USB cable, coil and spark plugs

Please note: the 123/TUNE will be delivered WITHOUT shielded USB-cable. The manufacturer advises you to use a Belkin cable, of course you can also order this here. Below you’ll find a picture from the cable at ‘Accessories’ and you can easily add it to your cart.

In the same way you can easily order a new coil. Although used coils all look alike, they should be viewed with suspicion since one cannot tell from the outside whether and how often they were exposed to overheating in the past. Installing the 123ignition system will ensure that the coil will never overheat again in the future. We recommend the High Energy #2020 coil.

Perhaps you will also need new spark plugs? At 123ignitionshop we’ve added the spark plugs most commonly used in addition to the 123ignitions we offer. See: the spark plugs list.
