    [UPDATE] PCLink 5.6.6.3564 (on hold)

    Thanks ....... I have done two ECU's and both work just fine.

    [UPDATE] PCLink 5.6.6.3564 (on hold)

    I had FW 5.6.5 updated to 5.6.6 till now no problems. I have a race next week should I downgrade it back to 5.6.5 or I can keep 5.6.6? thanks
  3. Any love for this new feature? Any update is also good. Thanks! Dolfo
  4. Good to hear it's back on the list. Yes I have my analog gear position senosr wired in.
  5. Any news on this matter? Is it back on the list
  6. Hi, I have the same problem and requested this software fix too. Hope it's a easy fix and that it can be execute soon Thanks, Dolfo

    Calculate % clutch slip

    Hi Scott, Maybe you can put this idea on the wish list for the engineers to take a look at? Some ECU's have the option to put the gear ratios to calculate clutch slip using a speed senor on the output shaft. Thanks, Dolfo

    Calculate % clutch slip

    Hi Scott, I decided to make my life a bit easier and bought myself a new fury ecu. Now I want to configure the parameters so I can log clutch/TC slip % of my motorcycle. My problem is I don’t have a speed sensor on the input shaft to measure the frequency. I have a speed sensor on my output shaft. Is it possible to measure clutch/TC slip % with my current setup? It’s impossible to put a speed sensor on the input shaft. Thanks, Dolfo

    Gear dependent shift light RPM

    Thanks Scott! I will configure the shift light in PWM and set the table like you suggested. Will try it out next race.
  10. Looking for some nice ideas to configure a gear dependent shift light RPM. I configured and calibrate my gear detection and it’s working. Any ideas for the V Series ECU's? Thanks, Dolfo

    Calculate % clutch slip

    Scott, You’re correct about the negative clutch slip. I can see it in my data. I was off the throttle from 100% to 40% and lower. That’s when I get the negative clutch slip. The speed sensor see 4 teeth. I will try to get access to an oscilloscope so I can measure the amplitude of the speed signal. How can I make this signal stronger? Maybe get the sensor closer to the pickup?

    Calculate % clutch slip

    Hi Scott, Does this look right to you? I see clutch slip % goes into minus (negative) slip what is the explanation for this? Wheel speed has a delay before it will start reading. What can I do to get it to read as soon as the bike starts moving forward? This causes a big number of clutch slip % at the start of the run.

    Calculate % clutch slip

    bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb Hi Scott, Thanks for the explanation!! I forgot the say it was for a motorcycle clutch slip calculation. What I don’t understand is the: Selected gear ratio and the Differential ratio. The rest of the calculation is clear. Attached is a gearing worksheet of my motorcycle. Maybe you can tell me what I need to use for selected gear ratio and differential ratio for my calculations. Is selected gear ratio the ratio per gear? And differential ratio (17/43)? Wheel circumference: 1.356m (circumference = π * wheel diameter => 3.14 * 0.43m => 1.356m) First we need to determine the rpm of the driven wheel: 100 km/h => 1.667 km/m => 1667m/m wheel speed/wheel circumference = wheel RPM: 1667/1.356 = 1229.24 RPM. The wheel RPM then gets multiplied by the differential ratio to give the output shaft speed of the gearbox: 1229.24*?? = ?? RPM The output shaft speed then gets multiplied by the selected gear ratio to give the input shaft speed of the gearbox: ??*?? = ?? RPM So far I came with my calculations.Thanks, Dolfo

    Calculate % clutch slip

    Hi all, I have a question about % clutch slip calculation. I want to calculate my % clutch slip using my ECU log file. I’m logging Wheel speed (on output shaft) and also Engine speed (RPM). Is it possible to manually calculate % clutch slip? I thought export data to excel and do the calculation. I don’t have a spare DI. Thanks, Dolfo
