Summary of change:
I have used motec on GSXR1000 last year in a team which I had worked in. Motec M-800 is great but it is expensive. Genboard seem to have same or superior hardware specifications. http://www.nmine.com/msavr/newmironly.jpg '''Motorcycle racing aplication of Genboard''' On the other hand, Megasquirt is not designed for racing use and it haven´t some fuctions than are very usefull in racing: *Quick shifter - to shift up with full throttle. It is very simple method, if you are full throttle and you try to shift then you feel than lever is very hard and it is unable to move because torque make impossible gears to be un-engaged. If you make quick throttle closing movement then next gear will be quick engaged, but you have lost 0.5 full throttle seconds and some rider concentration. MembersPage/JoseLCortes/QuickShifterSensorsTypes *Lower gear power output reduction - The GSXR and motoGP bikes have a shift gear position sensor, In the lower gears the engine power output is decreased. By the time 6th gear is selected the engine realises its full potential. The natural way for controlling power would be drivebywire but stock motorbikes haven´t it. Without drivebywire (==manual throttle), it can be done with ignition retard. Ways for controlling power: **Ignition retard ::Gear...........1......2....3....4....5....6 ::ignition.....15.....10....5....0....0....0 Looks simple. (but I doubt it gives the desired power-cut without event-skipping or air-control; too much retard will have the destructive ALS exhaust-heating effect, without the turbo-spooling benefits that justify ALS). ::injection..-20....-10...-5....0....0....0 (would be simple to implement, but this must be a bad joke, read about melting valves?) **DriveByWire or secondary butterfly. GSXR have a secondary butterfly (servo controled) before main buterfly (manual handled). It is the correct way in GSXR but no other bikes have it, implementation would be exacty the same than drivebywire. [http://www.nmine.com/msavr/sec_throttle.jpg throttle_bodies] **event-skipping like F1 but very scandalous. '''GSXR1000RK3 Engine Sensors Description''' MembersPage/JoseLCortes/EngineSensorsDescription '''Simulator Experience''' MembersPage/JoseLCortes/SimulatorExperience '''Motorcycle Engine eddy current dynamometer''' We have instaled a motec to work with a gsxr600 engine, this engine have been installed on a engine dynamometer for long time to make a precise adjust work, and I want to test the genboard at the same time than motec ones. My new dyno photos, The brake is a eddy current retarder from Telma, The engine is connected to the brake by chain drive with the chainwheel mounted over torque dumper. ||http://www.nmine.com/msavr/dynop/120_2049.jpg||http://www.nmine.com/msavr/dynop/120_2060.jpg||http://www.nmine.com/msavr/dynop/120_2064.jpg||http://www.nmine.com/msavr/dynop/120_2073.jpg||http://www.nmine.com/msavr/dynop/120_2080.jpg||http://www.nmine.com/msavr/dynop/120_2085.jpg|| ||[http://www.nmine.com/msavr/dyno/120_2049.jpg 120_2049.JPG]||[http://www.nmine.com/msavr/dyno/120_2060.jpg 120_2060.JPG]||[http://www.nmine.com/msavr/dyno/120_2064.jpg 120_2064.JPG]||[http://www.nmine.com/msavr/dyno/120_2073.jpg 120_2073.JPG]||[http://www.nmine.com/msavr/dyno/120_2080.jpg 120_2080.JPG]||[http://www.nmine.com/msavr/dyno/120_2085.jpg 120_2085.JPG]|| '''Adaptor PCB with stock Suzuki GSXR connectors''' I prefer to build a PCB adaptor and use original connector, in this way, this ecu is plug and play in any efi suzuki engine. ||http://www.nmine.com/msavr/board/1p.jpg||http://www.nmine.com/msavr/board/2p.jpg||http://www.nmine.com/msavr/board/3p.jpg||http://www.nmine.com/msavr/board/4p.jpg|| ||[http://www.nmine.com/msavr/board/1.jpg Sandwich1.JPG]||[http://www.nmine.com/msavr/board/2.jpg Sandwich2.JPG]||[http://www.nmine.com/msavr/board/3.jpg Sandwich3.JPG]||[http://www.nmine.com/msavr/board/4.jpg Sandwich4.JPG]|| This adaptor have a conditioning circuit for original pick-ups (cam and crank) copied from original ecu (very small SMD and silicone packed). IGBT´s have been placed in this board because original genboard will be cuted to reduce dimensions. '''Configuration process''' I´m trying to understand how config and tables works, in this way, I have configured my simulator for MGB 4cyl triggering pattern (crank and cam sensors). I have instaled LEDs on all 4 ignition outputs Make sure the cam-trigger condition on GenBoard/Manual/InputTriggerCamSync is met (until new last-tooth code stabilizes). Describe where the cam pulses are with respect to TDC. http://www.nmine.com/msavr/timing.gif It is the crank-cam signal measured with my USB oscilloscope. I think, it is the expected signal for tables of MembersPage/MichaelKristensen. http://www.nmine.com/msavr/36-1cam.gif Dump Tables: [http://www.nmine.com/msavr/configdump.txt configdump] [http://www.nmine.com/msavr/tabledump.txt tabledump] Firmware is 24-11-2004 recommended version and global.h is not modified my problem is than only IGN0 and IGN1 are fired (like wasted spark mode). I think there are any problem with synchronizing, I have check to cam signal arrive to AVR (IC3), any idea? Actually, it seems that it's configured so both edges reset the igncount to config.ignchmax(=03). Check that you didn't accidentally enabled OnlineCourse/AlienIgnitionLogging --------------------------------- '''My first testings''' Last two weeks I have been building a test bench with a car engine, The reason is than I haven´t GSXR engine, the team i was working for have broken, and i want to have a stable test bench to test anything without ask to anybody. http://www.nmine.com/msavr/1st_start.htm I´m using GSXR COPS in wasted spark ,My objetive is to add a cam sensor and use it in fully sequencial. I´m going to continue trying to install a genboard in a motorbike, Now there are a posible project with yamaha R6 engines. Jose L Cortes joseluis_jlc@hotmail.com
