? about shift-fast mod
I'm doing my 00vi swap soon and was thinking about the shift-fast mod too. I know it is usually done with a switch but is it possible to do this mod with a push button? It would be much easier for me to mount and I might even be able to costumize it into my shifter handle. Is it possible for a button or does it have to be with a switch because of the 12v power differences for each gear?

In one of the threads discussing it, Jime said it was possible. It will take a lot of creativity, wiring, etc. but it's possible. Once I get my "manual" 3-position switch version done, that's what I'll be aiming for. I'm hoping to create a steering wheel-mounted up/down button system.

I just figured it was much easier to use the button. I have no idea how to wire it up to make a button give power and stop power to the solenoids....guess I'll have to wait till someone figures it out

You also have to remember we only know about gears 1 through 3, we don't know about 4th. Maybe Jime knows? I don't think he ever told anyone since his setup is based around drag racing and therefore he only needs 1 through 3, 4th really doesn't matter.
So, we'll see how this all pans out, but, that's my idea, take it or leave it. I WILL be trying that setup at some point if I can figure out a good way to route the wiring out of sight (probably under all the panels), a good way to mount the buttons (just simple SPST push-buttons), and a way to make wiring that will turn with the steering wheel but not look hideous out in the open

About the pushbuttons - kinda like Pinks: " make a mistake, lose your ride". There is a better way.

One day I will figure out how to do upshift/downshift buttons, though. Mark my words
Also, here's my progress as of tonight:
Just need some more pin connectors, another spool of wiring (I was at the end of one starting this project), and I'll be able to tap in and get this bad boy going I need a better way to mount it, the switches are attached to cardboard right now I'll probably spray paint it black at least and write the letters/numbers with white-out or something. That will do for the time being 'til I find a good location and board to mount it to.

Solenoid............A...........B
1st gear............ON.........ON
2nd gear...........OFF........ON
3rd gear...........OFF........OFF
4th gear...........ON.........OFF
Does that help ?

So it could work with one switch if there was a relay that could switch the power....wonder if there is anything like that.
btw...do you guys have any links for VB mod? I want to look into that as well.

Hmm.. maybe later on next year if I'm bored I'll do something like this for you auto guys... not like I need it with my stick shift though...

Don't worry about boredom - My Shift_Fast.

Well I was thinking of a small logic circuit on a PCB board, but hey like most things in life there's usually more than one way to skin a cat.
But who am I kidding, I'm not going to be bored next year... in fact I'll probably be going crazy with all the house and car stuff I'll need to do... lol
... so have fun!

This version is proven at the track. Packaging comes later. Shift_Fast.

FYI to anyone who had been looking at the shift_fast write-up on my site, ignore it for right now. I'm taking it down as soon as I have the ability to (server problems right now) as the write-up is likely wrong at this point.
#26
Haha I'm trying. Even if I find the module I'm looking for I'm not sure if everything will work. Not sure what needs to be bypassed and what not. I have a sketch but I need some more details. I'll keep you posted.
I'm also working on trying to wire up relay's to route the power to the designated solenoids. PITA but should work to create power for all 4 gears. But again, not sure if it will work or if the car will shift back to normal. I'm not sure but I think with my setup the car won't shift down on it's own.....

There's more to this mod than meets the eye..... lots more...

If you have an add-on tach with shift-light stuck on the top of your dash, then maybe you could get lucky and button-shift before fuel-cut. Maybe. Short 23" slicks, 2800-stall torque converter, 150-shot of nitrous, and boosted-pressure automatic means things happen very quickly. Of course, with a stock engine and automatic, you'll have lots of time to shift to the next gear, and if you hit fuel-cut at 6650 RPM, nothing bad will happen...
Since I spray - a lot - I chose to build a version that uses the MSD to make the shifts. I've used both a manual 3-way toggle switch and the MSD version to spray with. The MSD (Shift_Fast) handles the shifts with no extra drama. It will also operate a shift light and cut off nitrous at shift-time.... I used a LED dome light made by one of the ORGers, and had the brightest shift light on the track! Hope this answers some of your questions...

It's like power tools - for hanging pictures, a little hammer is enough. When building a house, you need more....
#32
Yeah I understand. So what is your thought on this mod with just the 00vi swap. Will I still need a setup like yours? Tatanko seems to have one figured out and it's not as elaborate as yours.

I think that version would be suitable for you - I drove mine around for a while on street DRs and no spray on the street, and was able to shift with it - only had a couple of overrevs/fuel-cuts while N/A. Streetzlegend also built and installed the same type of shifter in his car....
#34
Correct, mine is the manual version. Still not working, unfortunately, but Streetz and I are making progress on it. Unless you track your car often, I'd say the manual version is plenty. Get some practice using it and it will even suffice for the occassional run to the track, and likely help your times, if only a little.
#35
Yeah I'm getting somewhere with my schematic but I dont know if it will actually work. I'll need some help once I get an idea for it. Basically the switch version but with 4 buttons that will suit my 00vi and DD. I'll be asking questions to you guys soon tho.

The switch stack I'm thinking of has interlocked pushbuttons so that only one can be pushed in - all others are released when you push another button.. Someplace like Digikey might still sell these.
Just a thought.... but it could work if you could mount the switch bank where you can easily get to it...
#37
That's exactly what I've been working on. I'm trying to find that box you speak of. So far no luck. I'll talk to my father and see if he could find something like it at work. My other thought was using relays to control the power but I'm not sure that would work.

Something along these lines? About 2/3 of the way down the page?

Awesome. That four gang maintained contact switches should do the trick. I do want the maintained conatact right? The other switch is momentary non-maintained. I'm guessing that's not what I want. I contacted Digikey as well to see if they had anything good.
Using this will make you manually down shift correct?
