Visit Preferences to set your user name Summary of change: 'Ignition Setup' I keep distributor only for distribution. I use Hall sensor on crank as a trigger input for the VEMS. Q: So actually I have to lock the plate in the distributor and remove the vacuumline in order to lock the vacuumadvance and let the distributor only distribute the spark? A: With the distributor used only for spark distribution, and not timing advance, none of what you described is necessary. The poles in the rotor cap are fixed, that is all that matters for spark distribution. Q: Do I need a triggerwheel or can I just bolt on two magnets 180° separate on the standardcrankwheel? A: With many auxiliary belts (air conditioner, servo steering, ..) this can be a problem to fit correctly. The main concern is that it must be rock solid and accurate, and be appropriate for the sensor you will use with the trigger solution. With a good Hall trigger (Honeywell GT1 is recommended) you don't have to use magnets, two slots or fields in a ferrous material is all that is needed and can be fastened in many ways depending on how the stock crank pulley is designed. In this day and age of cheap digital cameras, pictures still speak more than a thousand words, so get some snapshots. OK here is a pic from the crankpulley: http://www.vems.hu/files/Marteleur%20Tim/crankpulley.JPG This is how the engine looks on the output side of the crankpulley: http://www.vems.hu/files/Marteleur%20Tim/crankpulley2.JPG TODO: fabricate trigger setup with Hall sensor on original crankpulley I have setup the wheel with two bolts 180° separated and +- 60°BTDC. ---- '''Config''' * How do I determine the correct amount of degrees the trigger passes the sensor before the crank reaches TDC? ** remove a sparkplug so you can measure the piston height with a screwdriver or micrometer gauge. Rotate the engine slowly *** with wrench, from the crank (not cam!) *** or by moving the car, in gear 5 OK but then I still have to measure with a degreestool the exact amount of degrees the trigger is from TDC. This is not so easy to determine whether it is 60° or 61° or 58°? Measure the white dot (paint one if there is none) position precisely, and the trigger position only roughly. The dot is 0..10 degrees BTDC, quite easy to measure. This allows you to adjust the ign_tdcdelay with a TimingLight. You can also use permanent marker pen and use length-measuring tool (eg. at the circumference of a wheel) and calculate degrees. OK thanks I will do that. Here is my starting config and tables with a few questions in it: [http://www.vems.hu/files/Marteleur%20Tim/config.doc config] and [http://www.vems.hu/files/Marteleur%20Tim/tables.doc tables] * Can you publish the data in .txt format ? * space in file/directory name is not recommended, use "_" * good idea to write the questioned config variables in wiki (either bullet list or between <code> ... </code> (so it becomes editable, diffable) to increase the chance of getting answers (many people will not bother if they see that even you don't bother) Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
