Summary of change:
Current state: 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 (working) *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:''' Remember to publish battery calibration so we know AREF (287 or 256) for proper temperature table selection (that also precise at very low temp) I downloaded EasyTherm and filled in my three reference points: CLT: ; -2 6500 ; 20 2500 ; 160 50 IAT: ; 0 5000 ; 20 2200 ; 100 300 See EasyTherm cltfactor_2400_287.hex and airXfactor_2252_287.hex seems close (for above data) that can be applied to vems.hex with hexpatch.exe (that upload the patched vems.hex and there you go!). No need to change MegaTune. *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. ---- ''''31-03-06'''' Didn't dive into the CLT and IAT changes. Hopefully I'll get around doing that this weekend. I did see a spark. Next is fuel and CLT IAT calibration.
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
