BayAreaZT Posted June 25, 2004 Share Posted June 25, 2004 Some guy did this as a senior project. Would be pretty sweet in a Z. Here's a link to his write up http://mywebpages.comcast.net/lpearl/thesis.pdf Quote Link to comment Share on other sites More sharing options...
datsunlover Posted June 25, 2004 Share Posted June 25, 2004 That is awsome! Man.. I could build something like that too.. The shop I work in does all kins of tooling/fixturing using componants like that. Valves, air fittings/lines... its all just lying around at my shop! Well, it's packed up right now..moving to a new shop, but I think I'll try to build something like that for my RX7 V8 hybrid.. (next project.. heh heh) Very cool...

Mike kZ Posted June 25, 2004 Share Posted June 25, 2004 Dang, that looks like a lot of work just for a paddle shifter! I guess you really have to want one. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted June 25, 2004 Share Posted June 25, 2004 Been there, done that... On both systems I've done, the biggest problem wasn't the pneumatic circuit at all, it was the damn shifter buttons and/or paddles. It is actually much more difficult to get these working well and get a good feel with them than it is to design the rest of the system. As far as the pneumatics go, the solonoids and cylinders needed are easy to find in a variety of sizes, but are industrial items and usually fairly expensive. The other problem is writing a program for a microcontroller that is GOOD and works well with the system. This is probably where most of the time will be spent in the end, is tweaking the control system and program to a point that it works smoothly with the pneumatic system. In both cases my systems have been on a sequential tranny making them quite a lot simpler, but the adaptation to a non-sequantial system isn't terribly more complicated.

gramercyjam Posted June 25, 2004 Share Posted June 25, 2004 I had a chance to autox a car with paddle shifters - a buddies BMW M3 with a bunch of high dollar suspension mods and race rubber on it. Car was very quick and handled very well. When you hit the paddles though, my first reaction was WTF? WHEN is this thing gonna shift? It's cool and everything, but I think I'll stick with what I've got. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted June 25, 2004 Share Posted June 25, 2004 The systems I did had a 80ms delay, and that was just to give the air enough time to fill the cylinder. Quote Link to comment Share on other sites More sharing options...
