For 1st generation AiM SOLO DL.For 1999+ models with 16-pin OBD-II port under the dash or an aftermarket motorsport ECU.
The AiM SOLO logger needs to get ECU data from somewhere and this hardwired install is our preferred method. On modern cars with OBD-II electronics a lot of data is running through the factory ECU wiring or the plug-in diagnostic port in the dash. For most 1999+ BMWs this is the most valuable data*: RPM, speed, throttle position, water and oil temperatures, individual wheel speeds, brake switch, gear indicator, and more from just two wires.
This kit uses a open-ended wire leads for you to splice or tap into existing wiring near the ECU or OBD port. They can also be used with the RS232 protocol for connecting to an aftermarket ECU. Data is then transferred along the 4 meter data cable to your SOLO unit with a metal Binder 712 connector. No other cables should be required. The cable also includes power and ground leads to provide constant power to the SOLO (tip: find a 12v power source activated by your ignition switch, not constant 12v).
A plug-in version is also available (see OBD kit). There are pros and cons to both types. The hardwired RS232 version has a faster data transfer rate than through the OBD plug. There is also more data available by tapping the CAN wires directly. Hardwiring is more involved but no different than a stereo install. Professional install is recommended if you're not comfortable with splicing or soldering. Hardwiring is our preferred method for the faster transfer rate and it will leave the OBD port free for diagnostics or other uses.
* - not all functions may be available on BMW CAN sources. BMW decides which data is available through the CAN and it can vary from model-to-model. For more details on your BMW check out our AiM documentation
