Re: homemade h pattern to sequential paddle shifter

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

Re: homemade h pattern to sequential paddle shifter

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

Re: homemade h pattern to sequential paddle shifter

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

Re: homemade h pattern to sequential paddle shifter

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?

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

Re: homemade h pattern to sequential paddle shifter

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.
