Beta4 - shifting problems from beta 2 are back

[richard watson]

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

Same problem. I have a G25.

I have no problems with shifting on my G25, I use the sequential stick shift though.

Just to make sure, you do know you have to lift the gas a bit to make shifts possible all the time, otherwise they'll just work every now and then.

I did it that way and I have the same problem.

How many FPS have you in game? Maybe is one kind of lag or something

Hmm, I didn't hit every gear aswell, but I thought that was probably me, with not getting the revs right, caused by a lack of practice.

I have to admit I didn't drive the ks1 that much.

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?

Beta4 introduced several changes to gearbox simulation; mostly to try to remove the possibility to shift at limiter with no blipping.

In real life, is it really impossible to shift at limiter without blipping? In theory it should be possible, because power on the drivetrain is much lower than max and ignition is cut by the limiter.

In addition to this, there is always the problem of the time-shift between real life and simulator. In the simulator, when you fully press the lever, you are asking the physics to start the shift, while in real life when you fully press the lever you already are at the end of the shift.

To further complicate simulation, in real life you have feedback from the lever.

[richard watson]

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 think that there is not any kind of limiter on KZ engines. Maybe I am wrong as many other times, but how can it exist? There is not electronic in these engines.

And as a suggestion, KS needs a power big drop at, let's say, 15000 rpm.

[richard watson]

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.

[richard watson]

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 no problem shifting.
My timing is like this... release throttle (a little bit is enough) then shift.
I can't shift without releasing throttle.

A little bit means release the throttle fully for a few 1/10 of a second or release the throttle only 1/30 of the full throttle? (sorry for the bad english)

1/30 of the full throttle. ( I release it about 1/5 I think)

[Aritz]

yes, that is what I meant 30%, not 1/30
