Summary of change:
The University Of Hertfordshire has a lot of research into engine development. The university has got 20 years experience building competition cars, both in Formula Student and Shell Eco-Marathon. We are asking for help and support, in order to teach more automotive students about mapping and engine configurations using VEMS products, previously using Life Racing products. We aim to have a working dyno using the ECU and other VEMS components in a month, then implementing the system onto a larger '''forced induction engine.''' Just curious: * Why is a "larger" engine used for education ? * Smaller engines are more suitable for education (for several reasons). [http://shop.vems.hu/catalog/vems-p-48.html VEMS ECU with EC36 and EC18] * and what '''type of trigger inputs ?''' VR, HALL ? Or HALL,HALL ? ** please check the options, at least the important ones ('''select options''', and add to cart, and '''copy here for discussion reference'''). '''Specs''' * 4 ignition drivers (IGBT for passive igncoils ??) * 2 EGT inputs * 2 knock inputs * LSU4.9 wideband lambda control (1ch) * LCD connection * and removable SD card compatibility ---- '''Shop items''' * [https://shop.vems.hu/catalog/v3harness-pi-175.html Harnes to save time implementing the system] ** please note that even with a generic harness, detailed plans are still needed, of what to connect, and how * [https://shop.vems.hu/catalog/roundv2-wbo2-controller-p-166.html Vems Round] (or displayonly round to display data measured by VEMS ECU ?) ** Please create a page of what data is needed on LED and LCD displays. [http://vems.hu/android/ android] is usually favored nowadays (although some data on LED is more visible). The items can be donated, if * it's clear what IO (inputs, outputs) are planned to be used, * and what data would be displayed ** at least some initial plans / examples; of course many things can be reconfigured in software, but some things We obviously understand if you cannot donate all of these items but we have a keen interest in your products and aim to get our motorsport students using VEMS equipment. Thank you for your support VEMS Team! With your help, we can be much more successful at Shell Eco-marathon 2018 and we aim to travel to the Americas, Asia and the European events! ---- Please detail subsystems somewhat, so better verification of extra IO is possible. '''Analog inputs''' * TPS * MAP * CLT * MAT * VBATT (internally measured) '''extra Analog inputs''' * fuel pressure ? '''Activation inputs''' * shiftcut ? --- "Just curious: Why is a "larger" engine used for education ? Smaller engines are more suitable for education (for several reasons)." We have an initial testing/dyno rig that we want to implement VEMS onto which was using Life Racing F88 ECU. This is a Yamaha YN50F 4T and this was the engine used for this years Shell Eco Marathon car. We aim to downsize the engine for this specific application which should be carried out in the next 3 months with drivetrain. I suspect that if the VEMS is proven to be a contender for the Life Racing F88 ECU that we were using, I think that other projects such as Formula Student that are partaken at this University will also consider using VEMS, this is where the larger CC engines come into the formula. Other Projects that I have access to is a 20v Turbo VW engine that I'd like to do some testing with in the future, but for educational and development strategies, the smaller capacity engines will be the main priority. The setup is ideally looking to display data such as specific fuel consumption, EGT, IAT, CLT, RPM, VBat, Lambda, MAP. The rig will also be coupled to combustion analysis equipment from NI, so the more data that can be gathered, the better. Initial setup uses a 12.7ohm, 54cc/min injector, but as I will be building a bespoke engine for next years Shell Eco-Marathon and for research purposes, the setup is likely to change quite significantly as it is developed. The university is also wanting to take this engine development into the aspects of combustion analysis with an optical engine, hence validating any combustion analysis data gathered on burn fraction, knock etc etc.... Many thanks! :)
