Visit Preferences to set your user name Summary of change: Marcell Gal (from Budapest, Hungary born in 1976) worked with MembersPage/MichaelKristensen to enhance the design in several ways, eg. the improved controllable flyback and software EventQueue (that makes sequential injection and ignition possible) added GenBoard/MenuSystem, GenBoard/KeyBoard, WideBand, BoostController and many other stuff: this way founded the movement (which this site is part of). http://www.x-dsl.hu/~cell/cv/MarcellGal.jpg ---- '''Arranges logistics eg. WebShop''' Organized group manufacture, so 'assembled units are available': people have less work with collecting parts and soldering: except a few tall components like FETs and IGBTs are only mounted in the cased unit, while these few parts still need to be soldered onto the ultra-cost efficient still powerful 200 Euro GenBoard/VerThree assembled units. ---- '''current TODO:''' * ofbiz tasks * improved last-tooth trigger stuff * doc GenBoard/Manual * tuningsoftware ---- '''A proposal to mount ethernet''' - I bet it will never happen, we have RS232, 1-wire and soon CAN and USB. Maybe on a CAN-Ethernet board just for comm... <kakmnstr> approximately how much IO does the rtl8019 - avr interface use? <Letsmoveu> 8 for data <Letsmoveu> 5 for addresses <Letsmoveu> 3 for control lines <Letsmoveu> 2 ports <Letsmoveu> or, you may map rtl directly in high space of atmega128 <Letsmoveu> much better <Letsmoveu> or use other cheap avr, 8515 for example, and connect a port to atmega128 for data trasnfer <Letsmoveu> i like your project idea, maybe in extra time i'll write a module for your board <Letsmoveu> i have to go. my yahoo id is "seek25". if you go ethernet you can message me for some suggestions <Letsmoveu> have a nice day ---- '''Misc question on Honda cranking''' on a Honda Civic 1.4L 1998: is it possible that the engine won't start if I push the brake at cranking? (it's cranking normally, just doesn't start.) If I don't push the brake, it starts normally (not as fast as my Opel, but OK). '''A:''' Perhaps something to do with the brake booster feeding the engine "unaccounted for" air? Easy to check, just plug the hose. ---- '''Another 'little' meeting''' - happened in 2004. October * check mazda - nice * check Fero's another board, (AD597 needed supply) done * talk about OPEL tuning solutions * log the ignition map of OPEL pending * talk about future innovations * send out the EGT(in Celsius) and the AFR into the first page of the LCD * talk about other tuning softwares * .... ---- '''meeting in Budapest ...''' Next time: unscheduled * check out new Mazda with turbo * maybe install BoostController * talk about installation, usage * beer * review CAM-signal, maybe plan something * think about timing from last (crank) tooth * tuningsoftware related (Java, abeans) stuff ? (optional) please register here if you're interested (>10% probability) call me with any questions: +3670 2 654 789 ---- '''See also''' * MembersPage/MarcellGal/EngineSwap ---- '''VR polarity''' I have a little problem with VR polarity. On the Opel Astra (GM type engine, 1.6L 4cyl wasted spark, X16SZR ) 60-2 crankwheel transmitter. I think it must be VR not HALL, since there is no 5 or 12V supply on the connector when ignitions is switched on. # black-white (or black-grey ... it was a bit dark) # red-white (or red-grey) # black. this measures 0 Ohm from battery GND.''Probably shield'' ''I have never seen a multitrigger setup that use a hall sender. You can safely assume that it is VR. -Jörgen'' The car i v3-ed for a friend is an Opel engine with the 60-2 wheel connected at the crank, the VR sensor colors matched the colors you described. VR+ = red/grey, VR- = black/white and the black one is shield/gnd. With trigger_tooth = 08, another_trigger_tooth=1E and ign_tdc_delay turned out to be 0x9A. It's supposed to be the same for a Opel Motronic setups. - DB How to check? * connect DVM (200mV), move the hammer close to the sensor, than move away. One dir gives + voltage while the other - voltage. Which direction gives positive when the DVM is connected with correct polarity ? * apply a scope to check signal polarity * or make a histogram of times (reversed polarity has characteristic pattern). Thanx for the crank setup. I didn't expect so precise help so soon. In this case, I should ask about the coil-wires. It's a pack of 2 coils (bigger than the usual ford coilpack) with 4 signals: # black (I thought this can be 14V) # brown this measures GND # red-black # yellow-black possibilities for red-black and yellow-black: * 2 raw coil signals * 2 low-level coil-signals (IGBT in the coilpack). Polarity is question. * one is event signal, the other is home (only active for 1/4 or 2/3). Everything is question in this case. alien logging: * for now I assume I have 2 raw coil signals, which means falling edge means dwellstart, and rising edge is spark * try decimal 8 and 38 for trigger_tooth (depending on which coil-signal I tapped ) * while another_trigger_tooth=00 for alien logging (I just measure 1/4 or 2/3, not both) <Dave24_> we obtained ign_tdc delay with timing light (checked on both tooth 8 and 38) <Dave24_> so i think it should be pretty accurate <Dave24_> but there is a timing mark on the crank pully, when mark and the timing pin align is that is tdc I took some logs (in binary 22-byte and [http://www.vems.hu/files/MembersPage/MarcellGal/tmp/alien1xisRising2xisfalling.zip log in freetext megatune format] * RPM signal - the 60-2 multitooth wheel worked perfectly. (I flagged an rpm_calc once (not twice) per crank rotation, but doubled rpm_k[]). * MAP signal fixed (earlier maybe coolant valve or sg similar was connected to that channel, very low freq). * I wonder if the ignadv values are reasonable (besides any offset). Unfortunately the signal can be different type than we thought: I made logs with secondary_trigger=29 (rising, alien1x files) and secondary_trigger=28 (falling, alien20 file) * the dwell values .... well, should be good if ignadv is good ... but the ignadv is more important. <code> MY_CONF += -D SEND_DWELL_NOT_IAC MY_CONF += -D LOG_ALIEN </code> I made a suggestion (see comm.c) for runtime variable. ---- '''2005 July 7: EU parliament: software-patent directive is fortunately in the trashbin again''' No question the gangsters will try on, but at least they keep losing for now. This is tremendeously great for Europe: The economy can keep on building on fair competition instead of monopolies and law-mud. * [http://www.fsfeurope.org/projects/swpat/ Free Software Foundation site] There is already copyright on software which is just the right amount of legal protection. Making it legal to patent the patterns of thinking (which software patents are about) would have bad effect for the European economy. Only very few people (appr. 1%) would benefit: billionaires who have huge software companies that have dedicated lawyer-departments and portfolio of 1000+, possibly 10000+ , 99% meaningless, trivial and damaging patents; actually mostly outside Europe) and patent lawyers (there are many of them and they don't care how much harm they do to the society if they can earn a bit more). It would be a shame if these few harmful beings could blind people or blow off democracy. '''For now, democracy is winning'''.
