Used MembersPage/PhatBob/UserGuide
I'm using a BMW M20 6 cylinder engine simular to MembersPage/GergelyLezsak
It uses the following sensors and injectors:
-440CC injectors
-Stock single coil distributer
-VEMS Internal Map sensor (working)
-VEMS shop IAT sensor (values below)
-WB02 5057 sensor
-Other CLT sensor (values below)
-Volvo TPS sensor (working)
-Stock VR sensor (working)
I've downloaded the [VemsMT1.0.30rc3.zip] package and updated the firmware using UploadFirmware.bat. All sensors are connected and need to be calibrated. This is where the problems start:
'IAT and CLT:'
I downloaded EasyTherm and filled in my three reference points:
CLT:
; -2 6500
; 20 2500
; 160 50
IAT:
; 0 5000
; 20 2200
; 100 300
EasyTherm converts them into other values and makes the next three files:
-airdenfactor.inc
-matfactor.inc
-thermfactor.inc
These three files now contain the right sensor resistance/temperature tables. So both my Firmware and Megatune needs to be updated. I found the same files in the following folders:
VemsMT1.0.30rc3\VemsMT1.0.30rc3\MegaTune2.25b748\mtCfg
VemsMT1.0.30rc3\VemsMT1.0.30rc3\firmware\inc
So I figured I needed to replace these files and unload the firmware again, using Upload-Firmware.bat
This didn't work so I also tried using Tempsensor-upload.bat. This also didn't work.
I checked-out EasyTherm but don't understand what I need to do.
Can someone explain this to me in plain English I just don't understand the short talk on the Wiki as I don't understand the basics. For excample:
hexpatch.exe vems.hex < airXfactor_3000_287.hex > vems_1.0.30_airXfactor_3000_287.hex
Where should I run this?? Cprompt??
- 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 don't know how the battery calibration is being done. I'll try to find out.
'WB02 sensor:'
I'm looking into it right now. I tried yesterday but couldn't figure out how to do MembersPage/PhatBob/UserGuide instructions.
- 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 ?)
There are differences. But how can I reuse his setup? I don't know what files I should put in what place.
