Visit Preferences to set your user name 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.

IGBT´s have been placed in this board because original genboard will be cuted to reduce dimensions. '''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 R1 engines. --------------------------------- The R1 engine is here! ||http://www.nmine.com/msavr/122_2281p.jpg||http://www.nmine.com/msavr/122_2289p.jpg|| ||[http://www.nmine.com/msavr/122_2281.jpg 122_2281.jpg]||[http://www.nmine.com/msavr/122_2289.jpg 122_2289.jpg]|| Our mision is to install a Motec, but I hope to get install and test genboard in this engine, it is completely new engine, from a absolutely 0 km motobike!!! --------------------------------- '''My configuration questions''' --------------------------------- I have my engine running with fully sequencial ignition!!!, At the moment I have found one only minor problem, It seems to it mainly accurs with low battery. The first turn during crancking seems to apears strange firing sequence, the sequence is ign03, ign03, ign2 and ign1 (yes!!! ign03 are fired two times) and only one ignition is fired in correct cylinder!!! , With low battery it ocurrs continuously and engine don´t start, with charged battery it occurs one only time and the next cycle the engine starts without problem (some times it makes a ugly explosions when start for intake or exhaust) http://www.nmine.com/msavr/longcranking.txt It '''looks like some of the current to the starter motor goes through the ground that is used for trigger'''. This is called "ground loop". Make sure to avoid ground loops: * disconnect the onboard bridge ("arch") between GND and GND5 * connect all GND and GND5 ground pins with separate, sufficiently thick wires (0.75mm2 or above preferred) to a ground you call engine-ground (often at the battery). * shielded cable for trigger would be nice: the shield must be grounded on one end only ! * the trigger ground connects to GND close to the EC36 connector (not close to the engine-ground, and especially not tapping GND5) I think it's a '''firmware problem'''. Because i've got the same cranking trouble wirh the new firmware. The same system works OK with the older(2 month ago) firmware. I've got 4 cylinder with wastedspark. - Fero ----------------------------------- Hi, I am testing the last version v3_firmware_2004-11-24_v12, I don´t know if there are any of my problems solved, but I using this last version for my last testings. I have making a documented report of first cycle strange firing sequence. I have not a multichannel oscilloscope but I have builded a "channel multiplier": I have fit a diferent resistor (1k, 2.2k, 4.7k and 9.4k resistor) on each ignition output and i have mixed it to a only one oscilloscope input. This is the result: http://www.nmine.com/msavr/firstcycle2.gif Another test: http://www.nmine.com/msavr/firstcycle1.gif It is evident why the engine make a intake explosions during cranking. It seem only a minor problem in my old test engine (seat ibiza 1500cc), but it could be harmful for the yamaha R1 2005 engine.
