Visit Preferences to set your user name Summary of change: '''Introduction''' In the progress of installing Genboard 3.3 on a Yamaha R6 engine, a 600cc motorcycle engine from the year 2000. Had som initial problems, but now the engine has fired up! Just have to adjust it to run properly. '''Data on the setup/install''' The engine is an 600cc, inline 4-cyl, fourstroke motorcycle engine. Revlimit ~15500rpm, firingorder 1342. I'm using the stock passive COP, connected in series (=> wastefire). Injectors are high impedance Bosch-units of standard design. The CPS is working together with a 8-1 wheel (modified stock wheel from a '05 Yamaha Fazor motorcycle, perfect fit on this engine). No cam sensor. [http://www.tfd.chalmers.se/~burenius/vems/cellen.jpg Current picture of the engine, in its cell] The GenBoard is a preassembled v3.3-board with the following options: 4+4 ignition drivers Knock + 2 EGT 250kPa onboard MAP PowerFlyBack VR Primary Trigger Hall Secondary trigger [http://www.tfd.chalmers.se/~burenius/vems/vems-schematics.gif Schematics]. ---- '''Trigger problem''' The engine currently runs fine on the dyno, but I have an ignition timing problem. * '''8-1 trigger wheel: 1 tooth is 45 crankdegrees''' * triggering on the second tooth. What does this mean ? trigger_tooth=02 ? (dump config with Manmcd, and publish it) ** which gives only fifteen degrees to TDC. Since I want to be able to run with an advance of about 50-55 deg, this is way to little. * When I try to change configuration to trigger on another teeth (e.g. teeth #1, which gives 60 degrees to play, not 75!) - the engine won't start. I've tried every possible configuration. ** Publish what you try in exact terms (trigger_tooth=..). ** You likely made a mistake in the calculation. '''Decreasing trigger_tooth by one''' means going from 15 to 60 degrees, NOT 75 as you wrote !!! So you '''change ign_tdcdelay by adding 45 degrees''' (add decimal 90 if you do it in the config.txt file, because unit is 1/2 degree) Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
