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)
Peak and Hold
PWM % lasts typically 1.0 ms.
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 |
MegaTune is a software to change / tune config/table values in VEMS controller:
- How can I select full sequential injection?
- alternate=... (cylcount - 1)
- injection sequence h[0]= ...
