Summary of change:
Project: BMW E12 with an M30B35 engine from an E34 '88 currently controlled with standard motronic and running great. However I want more control and learn more about engine management systems. So I will make a break out box where I can measure all signals without cutting in the original wiring. I'll post a picture when it's installed. I installed a vaporized injection LPG system with Keihin injectors based on a master slave principle. Hence my interest in the new firmware release with dual mapping capabilities. ---- Current running affairs: *Waiting on loom connectors and some additional items so I can start my initial testing and datalogging with Motronic still in control. *I love to learn more about the firmware itself an more detailed inside information for development purposes in the future. Hence the BOB so I can preform easy testing. ---- [\ MembersPage/JanSaenen/Links Links] [\ MembersPage/JanSaenen/Buylist Buylist] [\ MembersPage/JanSaenen/Vapourised Injection] [\ MembersPage/JanSaenen/Progress] [\ MembersPage/JanSaenen/Config] ---- '''EGT''' My GenBoard (preassembled '''serialNr=355''') MegaTune will log both mcp3208channel4 and mcp3208channel3 (raw values). However, only mcp3208channel4 is displayed on LCD page0 (mlp00). Raw values mean that the * real_celsius_value = egt1_offs + (raw_value * egt1_cal / 256) where typical values: ** egt1_offs=00 ** egt1_cal=49 (that is decimal 73) '''Fuses''' These are commonly used : ||'''Current consumer'''||'''Fuse rate'''||'''Description/Comment''|| ||VEMS Genboard||'''3A'''|| It actually draws a couple of hundre mA, but this is the smallest automotive fuse commonly found in gas stations|| ||Lambda||'''5A'''|| || ||Injectors||'''10A'''||This could be the main fuse, and a separate 3A fuse for each injector for safety if you get a short in an injector you could fry the driver with only one main fuse|| ||Ignition coil||'''10A'''||Possibly even higher, depending on the coil primary resistance|| ----
