Summary of change:
Rob Humphris - Cambridge, UK. http://www.vems.co.uk ---- '''VEMS Wideband Guage Question''' I have been asked about the effective operating range of our Wideband system: What level of accuracy does it provide for ethanol fueled engines? ---- '''Currently Developing''' UsabiLity UsabiLity/GenBoard/WinTools PIDControlTuning MembersPage/PhatBob/UserGuide MembersPage/PhatBob/ToyotaFitting MembersPage/PhatBob/Marketing VehicleFitment/Toyota VehicleFitment/Honda VehicleFitment/Nissan ---- MembersPage/PhatBob/MagnettiMarelliSensorProblem MembersPage/PhatBob/PurchasePage MembersPage/PhatBob/ConfigProblem ---- The closing times are also needed (it is the function of injector current and flyback voltage). The flyback voltage actually makes a huge difference. The opening times are not (by far) enough to calculate GenBoard/Manual/Config/InjectorOpening parameters. You can start from other's values, make sure * injopen=00 (or very very short for low-voltage flyback, max 100 usec) * battfac=10 (256..700 usec is usually OK) * injocfuel=2C (500..1200 usec usually) * injrampup_battfac=FF (IIRC 4082 ... in MegaTune, it does not have a simple physical unit like "usec" or similar) ---- http://vems.hu/www.vems.co.uk/VEMSWB/VEMSlcdDark.jpg http://vems.hu/www.vems.co.uk/VEMSWB/VEMSlcdLight.JPG http://www.pgmfi.org/twiki/bin/view/Library/EcuSensors ---- v3.2 Assembly documentation: v3.2 How-to power-up a new board. http://vems.hu/www.vems.co.uk/VEMS/ ---- In an attempt to document my installation: * GenBoard/InstallPage/PowerUpToBootloader For UsabiLity to be more useable studies like this are of interest. http://www.useit.com/alertbox/reading_pattern.html

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.
