Summary of change:
VEMS install on '''90 degree V2 Honda engine''' - essentially an 8 cyl engine where only 2 cyls exist ectually '''Firing order''' 360-90=270 and 360+90=450 degrees * assumption: ec36/34 (cyl1) fires first ** cyl1 injection = ec36/ ... ? ** please '''correct the data if necessary, and delete this line''' * than 270 crankdegrees later ec36/36 (cyl2) fires ** cyl2 injection = ec36/ ... ? The engine started (with factory trigger 12 on crank and 1 on cam, also called c014 or 24+1) * '''PLEASE UPLOAD that CONFIG'''. ** it's unreasonable to start from anything else, so this is a requirement of further support (it was explicitely requested earlier, but 5+ and 15+ manhours of the support-crew and the insteller and weeks were wasted because this was lacking) ** [http://vems.hu/files/MembersPage/HondaV2/vems%2012%20+cam%20inj-%20spark%20ok%20.vemscfg vems 12 +cam inj- spark ok .vemscfg] misnamed file is not for the 12 cranktooth (24 per cycle) but 15 (matching the 16-1) tooth_wheel=0F * However, the engine did not start easily (it should, because this is a motorbike). Needs more investigation. * Also, at sudden transients trigger error appeared ( and loss of power). ** so the '''installer changed cam-wheel to 16-1''' (so that crank/cam race condition cannot happen). This engine has proper gear-driven camshaft anyway (not belt). ---- '''16-1 on cam''' - since this engine has a proper gear driven camshaft (not a sloppy belt), the camwheel without crankwheel is perfect. [http://www.vems.hu/files/MembersPage/HondaV2/16-1onCAM Settings] for 16-1 wheel on cam * tooth width=45 deg * next trigger tooth=2 (which gives 90 degree) * 8 cyl (even if only 2 cylinders are actually used) ** output 2 and 3 are actual outputs, 4,5,6, 4,5,6 are not actually connected (to anything) http://www.vems.hu/files/MembersPage/HondaV2/16-1onCAM/HondaV2_as_8_cyl_16-1_onCAM.PNG ---- '''Triggerlog needed''' - upload the triggerlog * with both rising and falling edge for HALL primary trigger * if both crank and camsync are HALL than this is 2*2=4 combinations The '''triggerlog is important''' to see distance between primary trigger and secondary trigger. If they are too close, than sometimes the sectrig will come before, sometimes after the given primtrig pulse => the engine will start hard, misfire at certain revs or transients, or not work at all. '''90 degree V2 overview''' * same as an 8cyl, just 6 cylinders are missing * honda vtr sp2.V90 * ecu: VEMS v3 firmware 1.1.81 serial no:3410. * angle between cylinders is: 315 and 405 crankdeg (360-45, 360+45) ** ! * factory ignadv 15 crankdeg * intake valve opens 20 crankdeg BTDC ---- '''Trigger almost 16-1 type HALL jeladóval While it commands sparks perfectly without sparkplugs, with sparks the RPM-changes are extreme (during cranking): http://vems.hu/files/MembersPage/HondaV2/16-1%20gyerty%e1val.png Please '''upload the triggerlog''' (captured with sparkplugs) so we can analyze properly ! From gimp measurements it seems: * 66/38 = 1.7368 * 57/27 = 2.1111 ** so around ''180-190 % threshold might be good.''' * trigger timing: tdc after the trigger 121 deg. '''Pattern:'' ** ??? degrees (15 is best, 10-20 can be acceptable) ** '''We want to help by verifying this, that is why the triggerlog is required''' ** '''we assume 15 crankdeg distance here''' * cyl2 TDC cyl_1 ** assumed 450 deg after cyl1 TDC, '''assuming 429 deg after crankpulse0''' (429=450-15-6) ** if in actuality 270 '''Proposed config''' * toothwidth=45 degree ** because this is crankdegree (22.5deg is WRONG) * next trigger tooth=2 * trigger tooth =0 (which is 0 deg.) ** Change it to 1 if the "TDC after trigger" is more than 127, and subtract 45 from "TDC after the trigger" value * TDC after the trigger: 121deg * with above settings, TDC points come 69 + N *90 deg after crankpulse0 ** the existing cylinder cyl2 is at 69 + '''4'''*90 (=429) ** the existing cylinder cyl1 is at 69 + '''7'''*90 (=699) http://www.vems.hu/files/MembersPage/HondaV2/v3.3_u001212-A-2011.03.16-17.54.52.vems '''Ki kell javítani mert nem egyértelmű ! Egy adott ponthoz (általában cyl1 TDC) kell mérni minden eseményt/pulzust főtengely-fokban !''' * az 1 henger alsó holtpontjánál ad jelet illetve a 2es henger alsó holtpontjánál is. * mert a cam sync jeladón két jel van 1 tüske és vele szemben (???) 2 tüske. * 1. tüske: 90 BTDC cyl1 csak hall felül ---- '''injektorok''': * hengerekként 2 injektor van a fojto szelep után egymással szemben ezeket párhuzamosan kötöttem mert Ákos azt mondta elbírja (magas inpedenciás inj)kapcsolt plusz és negatív * EC36/7 cyl 1 * EC36/19 cyl 2 ---- '''Sensors''' * Bekötve a wbo2 és kalibrálva * tps kalibrálva * víz és a levego is kész * egt kalibrálva * map kalibrálva -- ---- '''Actuators''' * Coolant fan now working start - connected s259 5 inverted ** ** for this special "8 cylinder" (with 6 cyl missing) we recommend to use a stepper output (or any non-injector output) for the coolant relay. ** If we want to time injection without -45 +45 degree cheating, we want to configure all 8 channels for inj - therefore no injector outputs available for other purpose ---- '''ALS''' * majd még szeretnénk ALS is 10fokos fojtóval max 5500 rpm ig.. ---- '''Ignition outputs''' maximum 185rpm inditózás közben. Ha a gyertyák benne vannak a motorba akkor trigger erort ir (nincs szikra se) '''Passive or active ignition transformers''' ? * '''ignition now connecting ecu36 pin36 pin34 (ign/2 and ign/3)''' ** 0 and 1 earlier was unfortunate choice for ignout: ** for '''passive transformers we recommend EC36/34 and EC36/36''' (ignchannel 2 and 3) because those are also available in the 2-IGBT version ! See [http://www.vems.hu/wiki/index.php?page=GenBoard%2FManual%2FIgnitionOutput ignout] (also referred from [http://shop.vems.hu/catalog/assembled-controller-p-48.html assembled controller in webshop] ) ** '''Our proposed initial config assumes ignchannel 2 (cyl2) and 3 (cyl1) ign outputs are used''' - but easy to change if you know what you are doing ** for active coils ignchannel 4 and 5 makes sense so available even in the 6 IGBT version ** with these recommendations the widest set of controllers (any 2-6 IGBT) ECU will be suitable ---- '''Test config''' * tested config with 1 tooth coil: http://www.vems.hu/files/MembersPage/HondaV2/v3.3_u001212-A-2011.03.16-12.09.16.vemscfg * configured: ** primary and secondary trigger, ** trigger tooth table ** inj and ign outputs * all other will check and set contact 06 30 276 75 75.
