T-VIS controller

Wed Jan 14, 2009 4:04 pm

Anyone happen to know where I can get one of these? I found one company and the website doesn't work. I think it would be nice to make a few little adjustments with something like this. Or if anyone has any ideas on how to make one that would be awesome too.

It's just a glorified RPM switch. All you need is a MSD or similar RPM switch and a relay, and you can make TVIS do whatever you want. If you want to get fancy and add a second axis of tuning to the system, you can also add a vacuum/pressure switch.

I think the guy who designed that was a member here. I don't remember his screen name though.

So I was looking at this. Would I still need a relay? This is kind of what I'm looking for, i can set it to say 3200 rpm and have tvis open the butterflies at 3.2k and stay closed under that. The other question I have is about the pressure/ vaccuum switch, what would that do for me in addition to the rpm switch? I'm in school to be a technician and had some electrical classes so I'm not really scared of this stuff just want to get the right idea before I go about it wrong. Thanks for the help!

yea, a buddy of mine picked up the controller from apampe.... a lil low-budget for me.

when my st165 was stock other than the constant run and 14 psi, i could feel it open at 4300 or 4600 something like that so i'd agree with the pressure switch or just deleting it

I'm probably going to delete it. I'm buying another manifold to do some tests with. In one lab at my school we have a flow bench so I'm going to do 3 seperate readings. One will be with butterfly valves closed, 2 will be with butterflies open to show tvis activated and then the 3rd will be with the butterflies and bars removed to see how much restriction is there with the valves and the bars even when they are open. I don't have the class yet so I either have to talk to the instructor and get him to do it for me or wait till I have the class. I'll open another thread for that when the time comes, I'll keep everyone posted.

Does the t-vis activate on both a solenoid and vacuum on the factory ecu?
I am wondering if you can control it from an ems.
just have the ems activate the solenoid at rpm etc...

I think the only gains you will see from gutting the butterfly's will be over 3-3500 rpm. I wonder on a basically stock motor if the tq loss would be that noticeable.

he didnt mean he is ballin, he ment it was a peice of crap. i had to open it and redo every solder connection. it didnt even turn on when i got it. and the built in relay does not have anough power to activate the vacuum valve. so i needed a better relay.........................btw it is huge as hell. like the size of an old ps2.

sorry to resurect the thread,
my solution is simple, pressure switch and relay as an inverter, so when boost come on the tvis is in the open butterfly mode,otherwise it is in closed butterfly mode
