Electronic Non Sequential Switch?
There has to be a way to do this, right? I mean, the second turbo is brought online by a signal to a solenoid, shouldn't you be able to "fake" that signal with an external switch and run it in Non-seq or Sequential, depending on what position the switch is in? I have heard of this mod for the Supras, but has anyone tried it on an FD? A search didn't find me anything

yeah as far as i know i originated this mod a couple years ago but i have since lost the info. basically you need a 3 pole double throw switch and one position connects the solenoids to the ecus signal and the other position connects 2 solenoids to ground and leaves one open (i think) the same way they would be after 5500 rpm.

On the note where it says boost creep may affect it, this is a non issue if boost creep is a non issue in sequential right?

does this non-seq to seq switching really works? I mean don't you need to wire the TCA door open when you go to Non-seq? How is this achieved by just taping into ecu?

The reason you wire the TCA door open (or remove it) during non-seq conversion is that you remove the TCA.

the part i dont get is that the car has to be tuned properly for each setup...why risk blowing your ***** up by going non seq when you are tuned for seq?
seems silly to me...the fuel map needs of non seq over seq are completely and entirely different.
you should at the very least datalog the runs and see where you are...if you are able to run it without detonating in the first place.

I've done the NS switch mod. I'm not a fan of NS, but it is nice to play with some times.
Also, I have a question for those of you that have also performed the mod. On my car if I leave it in NS mode and then shut the car off, when it is restarted and i start to build boost it falls on its face (something to do with the MAP sensor reading). So bascially I have to reset the computer and then it works fine as long as it is shut off in seq mode. Does this happen to anyone else?

damn, i also forgot to ask, what if i Have that PFS ecu. The limitation boost switch says i can't do it if i have PFS ecu but non-seq switch doesn' say anything.

he said in his write up that they don't have it in the radio shack. I'll check anyway. When you look at that diagram for connecting to the switch, does that mean, i have to cut the ecu wire and then ecu side goes to one side and solenoid wire goes to the other side? I'm confused on that part.

I ended up using a relay. Easier to find than a TPDT switch and it allowed me to use a simple toggle switch that could be remotely located.
It's not hard to do, but it does take a little bit of patience since the stock wiring harness is low quality and doesn't have much slack.
