Tuning homemade h pattern to sequential paddle shifter

[panoramix3519]

Hello guys it is my first post at your forum. I fix something (i think good) not finished yet but i want to share it with you. Is for my punto mk2b.



And of course i wait your suggestions to make it better now before i put it on the car

 

[s and b]

very impressive
how long would a punto gearbox work for though seeing as you can keep the revs up during changes?

 

[dave]

be a lot easier if you started off with a speedgear gearbox

 

[panoramix3519]

if you read under the video i have programed an output from plc for launch control so you have the rpm you want and except that the program i have write has the option the clutch to be automatic or manual like before and this will make only the change after you push the clutch

I want a custom that i can program it to work like i want. this i can make it fro racing setup till normal changes i have all the options

hi yes
i read what you put
even did the greek translation
and watched all the video
wasnt being negative ,just saying 6 speed punto boxes are made of cheese

 

[panoramix3519]

oh yes i know that my gearbox is not for too much things for that reason i have put an extra option (you will see it at the next video when it will be ready) how many milisec after push the clutch to change the gear and after the gear is changed how many milisec to wait before release the clutch and the release speed of the clutch and the speed changes is adjustable

This has to be the funniest thing I've seen in a while. You do realise that this already exists?
It's called the Selespeed gearbox that Magneti marelli have been making for years, the difference being that doesn't require 50kg of mechanical parts heavy PLCs compressors or all the other crap you've included.

Also you're handing over control of your clutch pedal to a dumb solenoid? What fail safes have you built in to protect the clutch if clutch solenoid fails to engage? Or what happens if it misses the gear and needs to re-engage, I'm sure you're very pleased with what you've made and it makes a great science day or college project but anyone with a bit of plc programing knoledge could put that together in half day, he'll my 4yo niece could probably do it.

Common sense would say fit the Selespeed gear box and take control of it via the obd port and software, it would be faster more reliable than what you've built safer and stronger.

What you've built is a bit of a joke sorry I've worked in electronics and engineering long enough that this has given me a good chuckle.

A version of the Selespeed is fitted to the Ferrari f355 as well as numerous fiat brand cars what you've achieved is a poor copy of already existing and well fettled technology

 

[panoramix3519]

from what are you saying everybody who have an idea can understand that you dont know anything at all from mechanics electronics and programming. If everything fails is checked from the plc every milisecond and for everything goes wrong it has a backup program. If you compare this with selespeed you cant understand what i fix and what you have seen. I am very happy to know that guys like you are very lelous that they cant fix anything by them selves and the only thing that they know is to say theories and i am very sad that guys like you thinks that they know everything and they are destroy forums like this one. I just want to share something with you but if you dont want i dont care. So bye bye i dont want to be a member of this forum.

That's a bit harsh isn't it? The guy was sharing his project with us, which he accepts isn't perfect, but you've shot him with both barrels!! Nobody is going to try to put this on their own car so what harm has he done?

Andy, do you ever have anything positive to say? Cheer up you grumpy sod!

Good work panoramix

Plc I stallation and ladder logic are taught to electronics students at BTEC/hnc level in the uk, anyone who has ever had an ounce of electrical engineering and electronics training can install and program that Plc, yes I was probably a bit harsh but then again had you not come here claiming to have reinvented the wheel then I wouldn't have been so. the stroppy attitude towards criticism shows you clearly think this is the best thing since sliced bread, yet anyone can go today amd buy a system like this for racing applications. in evolutionary terms you've needed a hammer so picked up a rock. dave stated early on that you'd have been better off starting with an automatic gearbox he suggested the cvt which would be far superior because there is absolutely no loss of drive between gears and no clutch what you've done is crudely robotised a manual gear box which as already been done. The reason other people haven't done it is not because it's hard, it's because it's pointless,

And until it's working reliably in a car it's nothing more than theory anyway

Seconded..... good job.
Thumbs up

Looks like a fantastic project. Good luck, and I look forward to seeing the videos of it fitted and running in the car.

Yes you are completely correct. You are a grumpy sod who at arms length have flattened the guy and given a very bad impression of the forum at the same time.

bla bla bla i forgot that you know everything. Maybe you are better than me and you can write me a better program to run it so write it and dont worry if it is better i will pay you for the 5 minutes that you need because as you wrote to me before if a 4yo child can do it in an afternoon that means that you can do it in 5 minutes lets say. And i am still saying that if you dont know the deferent from this with an automatic ....... that says everything. I will not continue this conversetion doesnt worth you are the best of all i congratulation you.

 

[AndyRKett]

And i am still saying that if you dont know the deferent from this with an automatic ....... that says everything.

Not really, the Fiat Selespeed gear box is a manual gear box with a clutch and manually selectable gears, it uses an ECU and Hydraulic servos to select the gears much like your contraption, that way it can be controlled by eletronics for automatic function or make the gears manually selectable by the gear stick or steering wheel paddles, its what you've built only fiat have been fitting it to cars for the last 10 years or so.

bla bla bla i forgot that you know everything. Maybe you are better than me

i'm not as childish as you, close but not quite

 

[pooroldcodger]

Panoramix. I think you can see that you have got some support for what you have achieved. Do not get drawn in to the argument with one individual, then you stay on top.
Good luck, and I for one look forward to hearing how far you take this idea.

 

[Honeymonster]

I have to say I think what he has achieved is very impressive, especially on a mechanical level. But I also have to agree it's not going to be on par with a Selespeed that changes gear in 0.7 seconds.

As for reliability, it could be made of chocolate and still be on par with Selespeed.

Selespeed:

So I do take my hat off to the guy and say what he is achieved is impressive for a chap working from his garage.

It's obviously not going to be on par with a gearbox developed by a car manufacturer involving collaboration of many skilled individuals. The Selespeed is based on race technology (hence the 0.7 second gear change), which is probably why it only usually lasts about the equivalent time of a few races race in a road car before it needs recalibrating or the actuator seizes up...

So I say well done that man for your efforts , but I am kind of confused too.

 

[panoramix3519]

my english is not so good so let me describe it again for missunderstandings. I never said that you will see it at the next fiat or ferrari model. I fix this from every old parts that i have spare at my garage. I fix that for my punto for track day use. The deferent from selespeed is that i can adjust everything like i want. The selespeed needs calibration because uses one multyposition actuator this one uses as you see deferent cylinder and every cylinder full stroke for every movement so you adjust it once and never again. When i put it on the car it will be only the cylinders and nothing else all the others i have put them just to help me write the program. At the video i work it at 6 bar and almost the half air flow at the car i can go at 10 bar maximum if i want so imagine the speed i can go double faster than the gearbox can effort. And the most important is that anytime i want i push "off" and i work the gearbox like it was before with the stick without any diferense something that with selespeed you cant doit. And as i think it my gearbox will last more time with this because the changes will be more acurate.And i have payed nothing to fiat thats good too and i fix it by my own so i am proud for this and you can say everything you want. I can hear any opinion good or bad but not from "people who knows everything but propably only in theory because practical i have never see something they have fix. Thanks the rest people for the suport
