VEMS install on 90 degree V2 Honda engine
The engine started please upload that config.
However, the engine does not start easily (it should, because this is a motorbike). Needs more investigation.
16-1 on cam - since this engine has a proper gear driven camshaft (not a sloppy belt), the camwheel without crankwheel is perfect.
[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)
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
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)
- gyújtás 90 fokra egymástól 1-2 és henger szinte biztos NEM igaz !
- factory ignadv 15 crankdeg
- intake valve opens 20 crankdeg BTDC
Trigger almost 24+1 type (c024 pattern in triggerplay) - originally 2-tooth cam CONVERTED to 1 tooth
- 12 tooth on crank
- originally VR, but changed to HALL on this engine ?
- toothlength=5.8mm (mechanically)
- trigger timing:
Pattern:
- cyl1 TDC
- "a camsync jel az 1 es henger felso holtpont után 6 fötengely fokra van"
- 6 crankdeg distance
- camsync pulse (between 2 crankteeth)
- ??? 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
- crankpulse0
- cyl2 TDC cyl_1
- assumed 450 deg after cyl1 TDC, assuming 429 deg after crankpulse0 (429=450-15-6)
- if in actuality 270 (it was not specified clearly), than ign output must be brought down 1 entry in the table
Proposed config
- toothwidth=30 deg
- next trigger tooth=3
- trigger tooth =0 (which is 0 deg)
- TDC after the trigger: 69 deg
- 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)
Cam sync with 2 pulses - and 2 VR sensors
- cyl1 BDC and cyl2 BDC
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
- Alul felül VR jeladók vannak!!!
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 cyl1
- EC36/19 cyl2
Sensors
- Bektve a wbo2 és kalibrálva
- tps kalibrálva
- víz és a levego is kész
- egt kalibrálva
- map kalibrálva
oscilloscopos mérés:5 voltos beállításnál a 10 szeres szorzó nélkül a camsync 0.16Vrms crank 4,35vrms
Actuators
- Coolant fan does not start - even if threshold configured lower than actual
- EC36/pin8 = inj 4ch.
- 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
Passive or active ignition transformers ?
- trannsformers on pin33 and pin35
- 0 and 1 seems 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 [ignout] (also referred from [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
