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 ...".
See EasyTherm on how to upload table with hexpatch.exe. With your temperature measurements (or sensor resistance at 1..2 temperature points) documented allows others to point to the best ntc curve (like 2700_287). For best result, do the battery calibration and publish the related config variable.
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??
Make pages for your subsystems and document your plans / progress / doubts / questions. Particular questions are easier to answer. If the engine is like MembersPage/GergelyLezsak you can focus on the differences (if no differences, you can reuse the setup - including config - as is, right ?)
