    Unfortunately on the rotax engine platform ive had to use another ecu as the bad starting and kick back issues i had with the link was damaging starters and bendix's ,in saying that i use link for most other customers and have no issues and love to use/tune them.

    Thanks Jase,

    I got onto another workshop who were more than happy to help me out. As I live in WA it can be a little bit difficult at times,

    Thanks to everyone who chipped in their support. I really appreciate the fact that I can get decent service from other dealers if need be.

    No Worries

    My mobile no is there so if you have any issues your more than welcome to contact me 

    I am also in WA and live in perth

  9. VVTI question Altezza

    in G4+

    Posted

    Yeah if you were having problems with the VVTI it would end up not tracking well when you overlay target / actual position but it seems fine. 

    If AFRs are looking good then I'd think you're getting some sort of misfire or spark issue as next thing to look into.

    Otherwise compression test / leakdown test I guess.

    Exactly what i was about to suggest,

    Do a compression test , change plugs , check air cleaner etc.

    You could also do a leak down test just to double check the health of your engine.

    Always a good place to start.

  10. trigger issue Rotax 4-tec

    Hi Jase

    The Vi-pec and Link units are identical no differences in firmware there are hardware differences on the plugins but that is just to make it a plugin, No differences in the trigger circuits or decoding.

    I would expect if you did a back to back the results should be identical.

    Hi Simon,

    Yes i know what your saying and have discussed with you these issues in detail previously,

    I have actually unplugged a V44 unit and with the same harness plugged it into the storm using the exact same map i had issues with the storm that i didnt have with the vipec.

    Now i have also tried a complete vipec plug in map on a storm and atom with the same kick back (trigger) issues.

    I am in the process of making a new plug and play harness for a customer that we will be using on a rotax 900 engine and extreme ecu, shit i really hope i can figure these trigger issues out as pulling the engine in this off road buggy is not a option.

    Any thoughts or suggestions are welcome

  11. trigger issue Rotax 4-tec

    Possibly bigger battery cables, bigger battery or a LiFE battery might help?

    If spare trigger wheels/flywheels were available and not too expensive, another thing I would try would be grinding off an extra 1 or 2 teeth to make it 36-3 or 36-4.  My logic here is with a bigger differentiation between the normal teeth and the gap it should help the ECU detect the gap.

    The problem here Adamw is on some of these engines it can be a engine out and strip to just get access to the trigger wheel at a cost of  between $1000-1600.00 min so its not cheap

    There has to be some way in the software or settings to help with this , Link still make a vipec unit for another aftermarket parts company that plugs into the seadoo factory harness that does not have these starting issues so there has to be a difference in how the triggers are picked up between the link and vipec units.

    Is this the 900 Ace engine?

    Im not sure why but in the days of the vipec we had this running our engines with out issue, when the vipec was discontinued and we changed to link we started getting kick back issues that i couldnt get rid of (trigger problems) .

    On our 4 tec engines we cant change the style of crank trigger (36-2) with out major costs and a engine out and strip to do this.

    I have also tried changing trigger voltages, changing rising to falling , falling to rising with out any joy ,but on the vipec i am running a trigger arming of 0.2,0.5,0.8,1.5,2.5,3,3.5,3.5" with trigger 1 filtering of 3 and a trigger 2 filtering of 2 and it starts and runs perfect everytime.

  15. Two-stroke

    Hi we use them on our 2 stroke jetski engines

    The tripples are yamaha 1100 and 1200 engines

    image.jpeg

    We also use the same thing on our twin cylinder seadoo fuel injected 2 strokes

    All i did was machined the trigger magnets from the outside of my mag then had a friend draw up what i needed via cad and had it water cut out.I had it rolled to the diameter of the mag and tacked it all together these work well to our rev limit of 7500-8000 rpm

    Hi Jase,

    I am going to help Håvard making this wheel. How many teeth did you end up with? 6-1?

    Thanks

    Hiya

    I can take a pic of one of my trigger wheels tomorrow when i goto work but i have made mine at 36-2 and 24-1 both work well

    Looking at your pic

    Your mag has 3 spaced pickups (magnets) at every 120 deg your stock ecu can work out tdc from this but the link can not

    You have the same problem we had so there was a couple of options, either add another sensor somewhere on the engine so you can run a trigger and home sensors so the link knows when a tdc event is or the way i went is making a multitooth/missing trigger wheel this worked for us no problem on our tripples.

    spelling

    How small can i get a trigger wheel? Will it not work with the stock pick-up? ( Arctic Cat Thundercat 1000)

    We just have them made to suit what we need,

    Can you send us a pic of your crank pick up and triggering?

  23. VE Tuning a rotary

    in G4+

    Posted

    all the rotary maps i have seen have been tuned in injection time, i just checked all my old haltech files and 90% of engines are tuned in VE except RX 7/8, why im not sure

    hopfully simon or scott will chime in here.

     

  24. G4+ Plug and play for EVO VI

    in Guest

    Posted

    Hi Mate,

    The plug and play will drop into your standard harness, the link software can be down loaded from this web site and includes a start map to suit the EVO VI of course if you have diffrent injectors you will need to do basics like install correct dead times etc but yes it will start your engine

    The ecu will control knock but on this unit i think a external controller is required, and yes you will be able to run launch control antilag etc.

    cheers

    Jason
