Rob Humphris - Cambridge, UK. Members/PhatBob/PurchasePage ---- Currently working on VehicleFitment/Toyota for a customer's Drift car ---- Morphon download: http://www.morphon.com/cgi-bin/shop/free-register.cgi?cont_url=/download/download2.html Please look at: v3.2 How-to power-up a new board. http://vems.hu/www.vems.co.uk/VEMS/ Please give feedback WideBand assembly: http://vems.hu/www.vems.co.uk/VEMS/WBOne/ I have an issue with ProductDevelopment ---- 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. ---- v2.2 successfully controlling a Subaru EJ22 engine, using a Ford EDIS timing wheel and an EDIS-4 to provide the spark and TDC pulse. http://vems.hu/www.vems.co.uk/msavr/PullyMountedEDISWheel.jpg v3.1 will be used as a high boost fuel controller to drive an additional 4 injectors on a Nissan SR20DET using a basic fuel map and relying heavily on WBO2 and EGT to ensure that the engine is correctly fueled. ---- Interesting site GM parts company Delphi sell an injector for Methanol http://www.delphi.com/pdf/racing/multecbottomfeed_meth.pdf I have an EDIS problem - someone please help, the voltages shown are when the PIP is high, when it drops low nothing seems to happen. '''Circuit is bad.''' read PIP part on EdisIgnition/FaQ more carefully * AVR should be GND on the above drawing. * the midpoint of resistors go to AVR's IC3 pin directly (no zener) * the midpoint goes to 5V via a diode (zener is also OK, but check polarity). The voltage readings cannot be good (if you can, specify high/low voltages read from scope. The voltage levels on IC3 is the most interesting): http://vems.hu/www.vems.co.uk/msavr/EDISModificationVoltages.gif When I probe (with scope probe? likely 1MOhm? Measuring resistnace in powered up circuit is bad) the resistors output at J8 (to the AVR pin IC3??) the voltage gets pulled down and the injectors open. ---- After suggestions on IRC the new circuit looks like this: http://vems.hu/www.vems.co.uk/msavr/EDISModV2.gif ---- Ideas regarding Aquisition ShopKeeping/DefinativeListOfSensors ---- http://vems.hu/www.vems.co.uk/msavr/vems.gif http://vems.hu/www.vems.co.uk/msavr/vems3.1mk1.jpg http://vems.hu/www.vems.co.uk/msavr/vems3.1bottom.jpg http://vems.hu/www.vems.co.uk/msavr/vems3.1draft.gif http://vems.hu/www.vems.co.uk/msavr/vems3.1top.jpg ---- In an attempt to document my installation: * GenBoard/InstallPage/PowerUpToBootloader * GenBoard/InstallPage/PowerUpToBootloader My website is: http://www.vems.co.uk
