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]= ...
- See GenBoard/Manual/DigitalOut, GenBoard/Manual/DigitalOut/Table,
Last update:
I've a lot of problems configuring my sensors.
I'm unable to find a write-up of what I'm supposed to do that I understand. I'm currently using Phat bob's MembersPage/PhatBob/UserGuide but I don't understand simple lines like:
Use EasyTherm to build tables.
Upload tables.
I got some new tables but don't know how I should upload them. Same about calibrating the WBO2 sensor. enz enz enz....
I put to much hours trying to find out how I have to do things. There's a lot of old info. Please can someone help me here??
