Summary of change:
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''' * adjust "battery calibration" in MegaTune * or (same, just different way) "batt_cal=A3" in etc/config.txt (or similar value; maybe higher like B8 depending if you have the AREF=287 or AREF=256 as on the bottom of BuildProcedures/SectionThree) until your battery reading is very close to your DVM measurement (like 12.4 V); and publish the related config variable. ---- ''''11-04-06'''' It seems to be working now but clt is slightly off. My batt calibration is 163. Atleast that's the value where megatune shows the same value as my multimeter.
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.
