Any setups that you would recommend guys...

Re: Launch control for road racing ZX10r

Hi Carry The Launch Control, does not control Throttle, the throttle is cable operated on these bikes. You should experiment with the correct Throttle opening for the launch, for a 600 I would suggest starting with 70-80% and go from there. When you are on the line and you pull the clutch in, the Launch Delay will start, after the launch delay has passed e.g. 2000ms the Launch RPM will engage and the engine RPM will be bought down to Launch RPM e.g. 9000 RPM for a 600. Once the light goes green you should release the clutch and launch the bike. Once the clutch has been released the Hold Time will start, this will hold the Launch RPM for a short amount of time to ensure that the bike has been launched off the line before the RPM Ramp Starts. The RPM Ramp controls the RPM from the Launch RPM to the Maximum RPM. You should set the Max RPM to be just above the redline so the RPM is controlled throughout the whole of 1st gear. The best launches are where you roll the throttle from the position you had at the start, to 100% and hold it to redline before shifting for 2nd. You can experiment with different Launch RPM, Hold Times and Ramp Times to get the optimum starts for your bike and riding.

Re: Launch control for road racing ZX10r

Hi all, I wanted to ask few things as I dont understand it fully. The bike is gsxr 600 prepared for drag, so red red red green and start;) So I would like to understand the process and it is not yet clear for me: Let's say here is my setup: Launch delay = 2000 ms Launch RPM = 7k Hold Time = 300ms Ramp Time = 2500ms Max Ramp RPM = 14k I go into the line and pull the clutch in for 2 sec and it should restrict the RPM to 7k - What about tps or any cutoffs? Can I keep the TPS on 0% and it will keep 7000 or I have to have tps on level exceeding 7000 to be restriceted? Is there ingitioncut or fuelcut on 7000? Waiting for a start i have 100% TPS normally, I let go the clutch and for 0,3 sec the 7k should remain for clutch to be disangaged - during that time can I keep 100% TPS? how is it solved? After all 0,3 is a huge loss in case of drag at the start... Should I calculate that into the start and let go the cluth before green comes in by this hold time to start exactly at the time of green to show up? After start it will start from 7k to 14k in 2,5 sec - what about TPS? should it be 100% or it doesnt matter? it will calculate itself to run during this time or will restrict to go under that time? What in case i would input here 0,1 sec or 1000 sec? how is it going to be? What after 14k is reached? If the acceleration was poor (ramp time too long) it will suddenly receive 100% tps and loose traction? I am confused as it looks like superfine product but I lack expiriance and perception to fully get it... If anybody knows more than was written before please do let me know...

Re: Launch control for road racing ZX10r

yes thats right, 700 ms is probably way too short for the ramp time, i dont think you would go from launch rpm to redline in that amount of time. You should also look at using the Vehicle Speed parameter, particularly if you ride the clutch, otherwise the ramp will start early.

Re: Launch control for road racing ZX10r

Yes the ramp comes in after the hold time

Re: Launch control for road racing ZX10r

There are a couple of settings for launch control, i would suggest you start with the default settings and adjust to suit from there. Launch Delay: This is the amount of time the clutch has to be pulled in before the launch control kicks in Launch RPM: This is the RPM the engine is limited to when ready to launch with the clutch in Hold Time: This setting allows you to set a short time period where the launch RPM will be maintained after the clutch is out Ramp Time: This is the amount of time for the engine to go from the Launch RPM to Max RPM RPM Map Ramp RPM: This is the Max RPM that the launch control will control the engine to, it is used in the Ramp RPM calculation Ramp Start Vehicle Speed: We had some issues with the first version with some of the riders who like to ride the clutch on the line, if the clutch is setup so the pick up point is outside of the clutch switching point the RPM Ramp was starting early, so the Ramp Start Vehicle Speed allows you to set when the RPM Ramp should start, this allows you to launch the bike on the Launch RPM and when the speed reaches this speed the RPM Ramp will start. It takes a little bit of practice to get the most out of the Launch Control, i suggest going to the drags or a quite piece of road and practice you starts until you "get" how it works. Dont ride the clutch too much, try and get the bike moving forward then feed the clutch relatively quickly. Just so I understand how the functionality works. Launch delay = 0 Launch RPM = 7k Hold Time = 300ms Ramp Time = 700ms Max Ramp RPM = 14k Start Speed = 0 With those parameters, as soon as the clutch is pulled in I could go wide open and it stay at 7k. I can understand that party easy enough. Then once the clutch is out and the switch is pushed it will hold 7k for 300ms? Then it will ramp from 7k to 14k in 700ms? Is that after the 300ms of hold time or as the 300ms of hold time is happening?

Re: Launch control for road racing ZX10r

Just following up. Hopeing for some support on this feature. I've not been able to find much info in the guides, install manuals etc. I will be racing this weekend in the 3rd regional round. Did not use the launch control in round 1 or 2 becuase not confident in getting it tested right in the race without some more info on the settings and even more imprtantly, what is the sequence to use it once I have activated it. I would like to use it in this weekends races to test it becuase have the Canadaian National superbike round coming up at the beginning of August so this would be one of the last opportunities to test it. Any info would be greatly appreicated. I'm riding a 2011 ZX10R with the Woolich LogBox, Strain Guage QS (GP-Shift), and Race tools Launch Control. Cheers!

Re: Launch control for road racing ZX10r

I would like to know more about this launch control also. Just a few questions: - is there a "default" setting that is already in the flash if the option for launch control is turned on? - what is needed to use the system? I'm road racing both regional and national in Canada and have yet to try it after 2 race weekends just due to not knowing enough about the system and not able to find much info. Thank you for any feedback.

The rider is having a problem with the bike coming up on starts. Is there any way to prevent this? The rear sprockets are 15 42 for about 69 Km/H in first gear at 7000 rpm. The launch control settings are Launch Delay 2000Ms, Ramp time 2500Ms, Launch RPM 7000, Max ramp RPM 14000, Hold time 1000Ms , Ramp start vehicle speed 65 Km/H. We tried Hold time of 100ms and it was really bad. Any suggestions would help. We are cooking clutches.
