Non-seq and Sequential SWITCHABLE
With all the recent talk about non-sequential, I thought I would provide a link to Gene Felber's web site. Go to "The Car", scroll down to "How-To's", then go to "Boost Limit and Non-Seq switches".

The switch allows in-car toggling of sequential and non-sequential mode.

i tried it, it works, cool to switch from the street for a seq setup to a non-seq on the track.
i also wanted to do it because i wanted to try the non-seq before a set of non seq.
decided i would stay seq.

A question for anyone who have done this....How effective is this conversion since it just electronic wiring and nothing was done on the mechanical side?
The idea is great with switching between NS and S but I kinda doubt that it would be that simple...then again what do I know.
If anyone have done this and it's effectively switching between the 2 with no il-effect please post...I will definitely do this mod on mine if that's the case.
Thanks a lot.

This is an awesome mod. Yes, I've done it myself (it's my page). It's great for the track- eliminates boost spikes!
If you have a modicum of soldering ability you should be able to do in in less than, say, an hour. If you want a nicer mounting like mine, then it will take a little longer to fabricate the braket.
Other benefits-
You can more easily pass emissions as the tester will be less likely to induce boost on the rollers.
Great for breaking in a new engine due to lower boost below 3500 RPMs
Great for warm-ups as you can much more easily avoid cold engine boosting.
Good for diagnosing upper RPM boost issues.
Good for tuning high-RPM/max boost (see below)
One other note- if you have a boost controller (elec or manual) this mods still works like a charm. In fact, I tune my Profec with the non SEQ switch. That way I don't have any surprises at the track.
Send me a note/PM if you have any Q's.

Gene

I've been using the switch for about 6 months now. No problems.

Gene, thanks. 1 more ?, I have the PMS and was wondering which mode should I go in on the PMS, the single or twin turbo mode? Would it control my boost like it should.
Hmmm...let me think about this abit.
Thanks.

DontBearikki,
Have you tried this switch method and if you have how is it compared to the one on your webpage?
Thanks.

Gene,
Per your instruction on the webpage, the 3 wires going "TO Solenoid", is it referring to the 4U wire on the back of the ECU or is it going to an actual Solenoid?
Thanks.

Ryan,
Yeah, your way is probably easier if you like wrenching better than wiring.
Anyway, I just brought up this mod so people could try it and switch back and forth a bit until they decide. Then if they decide they like non-sequential they could gut the solenoids, lines, and some of the flappers.

I am planning on ripping all that crap out over the upcoming winter (maybe sooner!) Does any one have any idea what kind of resistors you need for the harness?
J,
what did you use?
