| VEMS install on 90 degree V2 Honda engine |
| VEMS install on 90 degree V2 Honda engine - essentially an 8 cyl engine where only 2 cyls exist ectually |
|
The engine started please upload that config.
However, the engine does not start easily (it should, because this is a motorbike). Needs more investigation. |
|
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) ** [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). |

While it commands sparks perfectly without sparkplugs, with sparks the RPM-changes are extreme (during cranking):
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. |
| * toothwidth=22.5deg |
|
* toothwidth=45 degree
** because this is crankdegree (22.5deg is WRONG) |
| * trigger tooth =0 (which is 0 deg) |
|
* 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 |

* ignition now connecting ecu36 pin36 pin34
** 0 and 1 seems unfortunate choice for ignout: |

* ignition now connecting ecu36 pin36 pin34 (ign/2 and ign/3)
** 0 and 1 earlier was unfortunate choice for ignout: |
