Visit Preferences to set your user name Summary of change: Rob Humphris - Cambridge, UK. http://www.vems.co.uk ---- Well two days work and we have the Toyota running on Mitsubishi coil packs, they were simple to install and configure and seem to be plentiful. It was simple to get running on VEMS because its such a good system. Thanks to all those that helped with all my dumb questions. ---- Today's question... Rob, have you found a way to move the injector pulse through the 720 degree cycle? Thanks, Bill Hart Bill, After running batch fire every 720 I was advised to use semi-sequential, which I set to inject in the firing order of the engine, because I have two trigger events per rev I know that I am either 0 or 180 degrees out, it does not seem to matter. What trigger type do you have? ---- How is the knock sensor connected with assembled units? Is it: EC18-pin3 Signal EC18-pin2 Sensor Ground As specified http://www.vems.hu/manual/html/ch09s09.html If so what happens with external MAP? ---- MembersPage/PhatBob/MagnettiMarelliSensorProblem MembersPage/PhatBob/PurchasePage MembersPage/PhatBob/ConfigProblem ---- '''Currently Developing''' UsabiLity UsabiLity/GenBoard/WinTools PIDControlTuning MembersPage/PhatBob/UserGuide MembersPage/PhatBob/ToyotaFitting VehicleFitment/Toyota VehicleFitment/Honda ---- 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) ---- '''Nissan S14 components''' Coil on plug http://vems.hu/www.vems.co.uk/VEMSWB/COPAndSchematic.JPG Having checked the wiring pins relate to the schematic: http://vems.hu/www.vems.co.uk/VEMSWB/NissanCoilOnPlugSchematic.png http://vems.hu/www.vems.co.uk/VEMSWB/S14CAS.JPG ---- 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/ ---- '''Marketing pap''' VEMS gives you the full engine control that you need to bring out the best performance from your turbo/supercharged or normally aspirated engine. VEMS can be configured to use almost any standard OEM sensor for Throttle position. Coolant temperature. Air temperature. Crank and Cam sensors, Configurable for the 'standard' 36-1, 60-2 and customizable for different timing configurations. VEMS has an onboard Air pressure sensor (maximum XXXpsi) Additionally VEMS also provides the ability to use far more advanced sensors such as Up to 2 Wideband O2 (Low cost Bosch LSU4). Up to 2 Knock sensors. Up to 2 Exhaust Gas temperature. Using these sensors and sophisticated real-time software VEMS controls Sequential Injection of 1 to 8 fuel high or low-impedance injectors. (A Maximum of XXX injectors). Control of 1 to 8 coils for anything from single coil to wasted spark or coil on plug installations. Idle air control Fuel pump And unlike the competition with VEMS you don't have to have a costly Laptop to tune your car with, as a multiline LCD screen and PC keyboard can be plugged-in, which will provide you with all you need to monitor and tune the maps and enrichment settings. Throughout the development of VEMS, Customization has been by-word, we have provided miscellaneous control outputs for anything from Boost controllers, Nitrous solenoids, to Water Injection. As well as the capacity to measure two additional resistive values such as pressure or position. Datalogging capability is provided either direct to Laptop, or using an addtion Multimedia card interface. Rob, thanx, these are great. I guess we must split GenBoard/Marketing to GenBoard/Marketing/Logos and GenBoard/Marketing/Generic or GenBoard/Marketing/Features and move there. ---- In an attempt to document my installation: * GenBoard/InstallPage/PowerUpToBootloader * GenBoard/InstallPage/PowerUpToBootloader Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
