Maybe I should interrupt the crankshaft signal also..?Hello John, Thank you for your answer. Yes I do the interrupt with relay. And I use potentiometer to see the shift arm position, so I've made the program it see when should interrupt the ignition and if the arm reach the end position it gives back the power. So the interrupt time is hang on how fast I pull the shift arm, but it can be maximum 90ms.
I measured the relay can switch in about 3-4 ms. And I have read in the GSXR manual, if crankshaft position signal is produced but ignition coil signal is interrupted two times there will be error code. So in high RPM this is very short time.
Please see the shifting time, above is the potentiometer, below the power supply with relay. And you can see two shifting on the first photo.
Why? I believe most QS sensors are just a momentary switch.So the interrupt time is hang on how fast I pull the shift arm, but it can be maximum 90ms.
I basicly used this projekt Quick Shifter Under $50! Kazeshifter Arduino Adjustable Quick Shifter, but i thought alsó the relay will be too slow, but it seems it is working, because the switching time 3ms and the iterrupt approx. 40-80ms. Main problem is with the F1 errorcode, i don't know how the Ecu recognize the ignition iterrupt. Measure the current of the ignition coil or decrease RPM át same throttle position or etc. That i like to know how can i cheat the Ecu.Why? I believe most QS sensors are just a momentary switch. 1. you lift the shifter loading the mechanism 2. the momentary switch is triggered and tells the brains to perform a 40ms ignition interrupt cycle. 3. as soon as the ignition is interrupted, the bike shifts since you are loading the shifter. 4. The brain completes the cycle and restores ignition. Instead of a mechanical relay, why not use a switching transistor? Much quicker and reliable. I'm definitely not an electronics wiz but I don't think the injectors draw that much power.
I think this is your answer. Why try to fool the ECM, just shorten the interrupt time. Try 35ms or 30ms till the problem goes away. My guess is that your system actually has more actual interrupt time than you think.And I have read in the GSXR manual, if crankshaft position signal is produced but ignition coil signal is interrupted two times there will be error code.
I think that’s what the OP is getting at. As there is only 1 light and the FI icon, the OP is trying to not have the FI light come on for the ignition interrupt as that would mask any other cause for the FI indicator to light up.There is not separate oil pressure and high temperature icons on the cluster like the later bikes?
@Mora, I couldn’t access the site with the arduino code on it. Even though you might code a delay of 40ms, it’s possible that you’ll end up with a longer delay due to how the code may be written and subsequently executes.
As for the relay, I’d steer clear of a mechanical one and either use a solid state relay or a mosfet/transistor to switch the power to the injectors on and off. A solid state relay can switch in around 50ns which is way faster than the 3ms (3,000,000ns) of the mechanical relay.
Hi, Thank you for your comment and i aggre with the szolid state relay and i will change it later, but i thing the problem is comeing nőt from the relay. As you can see above on the scope photo, the interrupt is 20ms totally with relay on off switching time. And to change gearmechanically alsó need time, só if the interrupt time is too short i think it will be nőt enough to load switching/changing. I tried the car yesterday and the shift change worked well and very fast, but the terror come up. I thought what would happen if i interrupt the crankshaft signal alsó, because the manual write that if the ignition was interrupted two times When crankshaft give signal then the error come up.@Mora, I couldn’t access the site with the arduino code on it.

Yes Yes, this is my problem.I think that’s what the OP is getting at. As there is only 1 light and the FI icon, the OP is trying to not have the FI light come on for the ignition interrupt as that would mask any other cause for the FI indicator to light up.
Around 60-70 I get fails, I have mine at 45.Hi Dany, how long the iterrupt if you get F1 error? And can you avoid that? what are you doing in this case if you get error?
