Aaron's 1972 BMW 2002 Tii

Aaron's BMW has always stood out as an example of a well rounded 2002. Wanting to add a little character, tuneability, and power, Aaron chose to replace the Kugelfischer mechanical fuel injection with a modern electronic fuel injection system. A set of TWM 48mm throttle bodies replaced the stock intake manifold setup. Aaron came to me to develop a fuel injection and ignition setup around the engine's new induction configuration.

MegaSquirt II was the engine management of choice for this setup due to cost and flexibility to be adapted to this project. Josh at Yoshifab provided the laser cut the 36-1 trigger wheel that mounted to the engine's crank pulley. The MegaSquirt ECU was assembled and configured to run the fuel injection and distributorless wasted spark ignition system. A set of 24# Bosch injectors were fitted to the TWM throttles. The ignition system consists of a Mitsubishi Power TR ignition module and a pair of DSM wasted spark coils. The factory distributor has been eliminated. Air/Fuel ratios are monitored with a JAW wideband controller.

Aaron keeps a build thread on SDDSM, covering the details of the build.
