Project: BMW E12 with an M30B35 engine from an E34 '88.
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.
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_cal=49 (that is decimal 73)
These are commonly used :
|Current consumer||Fuse rate||'Description/Comment|
|VEMS Genboard||1A .. 3A||It actually draws a couple of hundre mA, but 3A is the smallest automotive fuse commonly found in gas stations|
|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||7.5A||10A might be too high to effectively protect.|
