Paddle Shifter Electronics

It's complicated to explain but basically involves alternative shifting between a overdrive unit and an automatic transmission using just a paddle shift arrangement. Usually such shifting is done using a sequential manual shifter for the trans with a button controlling the overdrive unit, the sequence being manual shift, overdrive shift, manual shift, overdrive shift and so on. Paddle shifting is not essential it's just that with a manual shifter there can be no gaps in between for the overdrive unit to shift.

I'll have to solve the problem myself but tips and sources for made up circuits that may be useful would help a lot. May have to educate myself on basic electronics too.

I've got a s2 arx stagea that would be very interested in a paddle shift setup once in the tiptronic mode (need to make sure my other half can drive it still).. was thinking maybe the g35 paddles could Frankenstein in and I know the bell works kit bolts in with ease.. would be super keen to know if what I am after is possible.. don't know if I'm off topic with what your writing or not..

Load of cobblers. Paddle shift is not going to give you 30% more power and torque. Existing controls will allow you to hang on to max revs in gears or change down early.  A paddle shifter on its own will not transform your car into a rally car or F1 race car. More of a problem on newer cars is the fly by wire throttle control. Look up ways to sharpen that up instead.

The video explains how to shift at higher RPMs for added performance compared to not shifting to at redline. Comparing the two options the former will shift with 30% more HP/torque compared to the latter.

If that video helps you, you need alot more help.

 

 

 

I like the final comment, cos I skipped pretty much all of it.

"When down shifting to increase power during a launch remember to upshift before reaching redline to prevent engine damage" lol

But that is specific to THAT car.  My car makes peak power at 6950 rpm.  Redline at 7400.  Power at redline?  About 5% less than at peak.  Time lost changing +/- 500 rpm either side of redline?  Approximately f**k all.  Such videos are stupid, by stupid, for stupid.


Not all cars are the same. The vast majority of engines have more power at the higher RPMs.

Why your car loses power at higher RPMs is very strange. You should probably take it to a shop and have a mechanic take a look.

You probably broke it or are going something wrong.

But you don't need paddle shifters to achieve your aims whatever they may be. If you read the manual and learn to drive properly you can change gear at max revs, less than max revs, kick down to a lower gear etc etc

That concern for his completely normal power delivery is cute ;)

And what's wrong with that? Should you not upshift and damage your engine?

The video strictly covers cars with automatic transmissions not manuals.

Its kind of stating the obvious and in any case any modern auto will change up when you hit the maximum speed for that gear anyway. As for the best place to change up it depends on a lot of things but on my Stagea it would normally be at 6000 if you look at my charts (attached)

A manual is a book that tells you how to operate the car!

The video was shot under the assumption that not everyone is as knowledgeable about their transmission.
 
Sure most transmissions will shift automatically but constant improper use can damage your engine. Every transmission has limits and shifting too late, too often, can and will most likely damage your engine.

Its a valid concern.

His engine is operating abnormally.

I'd be very concerned if I were him.

Oh, my goodness.  What a lot of rot.  My car is operating 100% completely as you would expect it to.  Not only that, but it was only the dyno on Wednesday getting the tune touched up and it is operating better today than it was a few days ago!!!

Peak power at very nearly 7000 rpm is just about perfect.  Anyone who thinks that a power drop off after peak power is abnormal, is abnormal.

Are you responsible for that video?  is it yours?  If it is, then perhaps just go back to 'merica and leave this forum alone.  We know not to bang our engines off the rev limiter.  There's a very specific reason for most of us not to do it.  If you know that reason, then you can stay.  Otherwise, there's nothing here for you.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
