I have never tried engaging any gearbox over ~ 5k - 6k. That said, it does go in to gear at those RPMs, albeit with more of a clunk/crash than normal. I am speaking of Honda CR 125 motors on karts specifically and 25+ years of motorcycle gearbox experience in general.

It is a short track, top speed is 70 mph, we run 14/26 to 15/27 gears. The track was kind of slippery that day, it grips up in the summer. Yeah 99 is a new guy, he is learning pretty quick though.

Club racing in Texas. Mixed KZ2, Modified and stock moto engine shifters. Track is short and racing a shifter here is brutal work, but fun!

Almost all of my driving IS offline. The problem I describe (nicely illustrated by dibu in the thread he linked) does get worse online, but is definitely there offline as well. In fact one of the main reasons I rarely go online is this shifting problem. Losing 0.3 to 1s+ a lap because of missed upshifts is quite frustrating driving by yourself. When driving with others the situation is simply untenable.

I am in agreement with Artiz - I would prefer shifting that is more realistic, even if that means "faking" it within the simulation. Though this may seem like sacrilege it really needs to be done. Clearly the simulation in its current state (with regard to shifting) does not resemble reality. Again I base this off the many thousands of real world shifts personally performed by myself, as well as others as demonstrated on video. In fact I have recently ordered my own gopro camera so that I can provide my own video demonstration of shifting in reality vs KRP.

From Piboso's input, my experimentation, and the experiences of others, it seems now that the most likely reason for this is that the simulation is used with micro switches on people's controllers, rather than an input device that fully simulates the lever, linkage, shift forks, shift drum, shift drum spring, shift drum roller, primary gear shaft, main gear shaft, individual gear clusters, gear "dogs", the slots with which these "dogs" interact, the oil film in between these various components, the counter sprocket, each part of the drive chain, main sprocket, axle, wheel, tires and road!

I am not bringing this up because I am an inexperienced @@#$%% that does not know what I am talking about! I bring it up because it is a real and serious problem that in my eyes could be the downfall of this otherwise fantastic sim!

Playing around with shifting times based on Piboso's comments, it turns out to be a timing issue  If I hit the shift button before actually lifting the throttle it seems to work. It feels wrong and the required throttle lift still feels large.

Is anyone using a newer/nicer wheel than the G27? If so are you using this kind of timing?

If you are having no problems at all with shifting, are you timing it like this (shift, then lift)? If not, what sort of hardware are you using?

I have a CR 125, which does not have a "real" limiter; the ignition is just drastically retarded (advanced?) at around 13,500 rpm. I dont know that KZs have a similar setup, but I do know they fall on their faces just the same if you over-rev.

I have never tried shifting throttle down at the limiter in real life. The reason is that in real life the drop off at the top of the power curve (which occurs before the limiter) is quite noticeable and keeping the engine in the power means shifting so that you don't run into this. If it is possible to shift at the limiter, it would be slow over the course of a lap because of the engine falling on its face before getting to the limiter.

Incidentally, I find that this drop off in power prior to the limit is difficult for me to detect in KRP, but any sim without a motion platform has this problem.

So it sounds like time lag between the simulation and my hardware may be a problem. My computer is up to the task, but perhaps the old G27 is getting a bit long in the tooth.

And finally, Piboso, this sim is awesome! The other current (rfactor based) offering has lots of great tracks, but what a waste of effort! KRP actually drives like a kart, the other one feels like the original Atari Pole Position in comparison. I use KRP to warm up before heading to the track on race day.

I don't think it is necessarily a timing problem - I have been playing KRP since beta 2, and did not have the problem with beta 3. I play a few other sims that have "realistic" (aka pain in the a$$) shifting. NKPRO and LFS. In addition I race shifter karts in real life and have tracked formula ford and various street cars. I fully comprehend how to manipulate the throttle during a gearshift in order to unload the gearbox. IMO no real gearbox is as difficult to use as the boxes in these 3 sims.

The fact that it came back in beta 4 (and there was no mention of a change) makes me think there is something happening with the install. My plan is to wipe out and re-install a few times to see if that does anything. Otherwise I wonder if there is any hope to the idea of tuning the duration of the button push, or if that would work at all. Has anyone messed with getting KRP out of their registry - or does it even have things there?

Richard

I have installed beta 4 and am liking the new features. However the impossible shifting I was experiencing in beta 2 is back. I think this must be some kind of hardware or calibration problem as I have been enjoying realistic, easyish shifts with beta 3. I did a clean install for beta 4 - deleted krp and piboso folder. I am using a G27 wheel and shifting with the paddles. Is there any kind of setting or ini file that has something to do with button timings or calibration that I might try playing with?

Thanks,

Richard

Searching on Freetrack, I see that it is compatible with Track IR 5 somehow. Has anyone set up a Track IR 5 through Freetrack to work with Kart Racing Pro? If so or even if you haven't but know how to do it could you post some noob tips on how to do it?

Thanks!

Richard

Thank You!!!! Thank You PiBoSo!!! Shifting is dead on now. Great to see Brand C kart as well as a new track!! Fantastic update!

i have g25 and for me it's not how you say, only a little bit of lift of the gas pedal then push the gear lever and the gear is up, i have had to training it so much for to do this quickly but it works well

I have to disagree with oppolo: the current shifting of the ks1 is unrealistic both with and without shift help. Your point that it takes training is proof of this. I have missed maybe 3 upshifts in 5 years of racing real life shifter karts, and I would put those down to times when my shift linkage was coming out of adjustment. In KRP i have completed perhaps 3 laps out of hundreds where there was no problem with the upshift. I have given my real life karts to countless newbs with no experince to drive and though they dont know when to shift, when they want an upshift, it goes in! Shifter karts are very easy to shift in real life - easier than just about any other vehicle you could imagine! (except probably an F1 car).

I am using a G27 wheel with default settings- i dont know if there is some kind of button dwell setting or what that would fix this?

Sorry for the rant, but this bug completely ruins the sim for me, which just kills me because I really want to enjoy it!
