Engine is a M73 from a 1995 BMW 750IL.
V12, built like 2 inline 6 single cam sharing a crankshaft.
First try will be from 2x OPF racing 54 way teensy 3.6, slightly modified:
-Ignition control removed (that engine come with 2 distributor)
***Will be change later as the target is sequential ignition
***Thank to "Ben" ? for the boards
-Wideband O2 sensor integrated modules
***Thank to "CANBED" ? for the module : https://easyeda.com/CANBED/slc_free_min ... controller
As soon as I have more info about "Ben" and "CANBED" Ill update the post.. (contacted them on easyeda..)
I will 100% need help with the firmware, so if anyone is interested please let me know. as I have to order the boards in batch I could exchange the extras for firmware work..
