But seriously, talk to me about electronic boost controllers. How are the ones that are out there? Do they do everything you want? Can you set up different boost levels in each gear? Can you have it do automatic traction control based on the rear wheel speed sensor? Do they work with the stock vacuum setup and only simple wiring changes?

Ok, let's chat.
Some have the ability to set up boost levels in each gear, although some of THOSE require external switching. Boost controllers that come to mind are DTEC, s-avc, eBoost. Not always the easiest to figure out, though.
Traction control = no. I'd love one that did this, assuming you're talking an ability similar to the TCS?
Stock setup and simple wiring changes = you know the answer.
If you could create a combo eBoost / TCS, I would DEFINATELY be interested.
Can you install 2-step, too?
right now I have a WOT box, which I'm very excited to get to the track with. If I also had traction control, a 2-step, and the ability to have lower boost in first and second gear.....well, I'd probably just explode with happiness.
Well, so why are none of them wiring only? Presumably the stock vacuum setup and solenoids are sufficient to control the boost. Am I wrong? Are there limitations to the stock vacuum setup? It would seem to me as long as you took over control of the WGA solenoid, you could set any boost level you want... I'm making 23-24 lbs now with my stock S3... Which is kind of funny because it is higher than the spec for OBD, so the data wraps around into the vacuum region!
I'm not sure what the general theory of traction control is. Presumably, the TCS guys chose ignition timing for the traction control for a reason. Perhaps adjusting boost for control traction is too slow? Although, I'm pretty sure that VEMS does it that way...
I see no reason to need external switches for gear selection. I got it working pretty damn well with just the OBD bus, and not even using active commands. Just passively looking at the data. :-) Of course, that is SRT specific, but I'm not too worried about that.
2-step certainly is an ignition only feature...
So, maybe an electronic boost controller is in our future... I might like to try turning up the boost on my car a bit... I imagine S3 has a few more pounds in it, at least once I do the fuel pump rewire mod...
Since no one's hijacked the wiring to use the stock solenoids for boost control, no one seems to know for sure how good or bad they may be.
However, you have S3, as did I at one point, and the DAB and regular boost control seems to be fairly quick, and obviously will run well over 20 psi.
Seeing as how we all still have our stock solenoids hooked up, if you could make all this work, I for one would love to try it.
gear-specific boost? Cutting boost when wheel spin in detected to regain traction? I'll be honest, I can't currently get up from my desk at work because I am so excited about the thought.
If you did something like that, how hard would it be to specify what amount of boost you wanted in each gear ( or at least 1st, 2nd, and the rest together)? I would think you'd need to make that easily changed by the user, so they could run more in the lower gears at the track on slicks, and less on the street.

Well, it would be very easy to specify what amount of boost you'd want in each gear. I'd imagine storing two sets of configurations so that the user could swap between a street and strip mode. I'd probably put more than one button and at least a two digit LED display. The single button interface I've made for the Toybox 2.0 is slightly awkward, but I think it is reasonable for settings that are not often changed...
Also, I'm not sure if cutting boost to control traction would work. I'm thinking that the response time might be too slow to be useful. It takes a while drop boost, so it might not be a good real-time system. However, it could learn what boost settings do and don't work well from repeated runs....

Also, I'm not quite as concerned with the traction control, if the boost settings are configurable. Obviously, I'd set the boost levels to whatever worked for that particular setup (street tires, slicks, etc...).

Yeah, that's what I'm thinking.
Would you need to be able to set the parameters directly from the EBC or would you be ok setting them through a serial cable and laptop? How often would you think you would change stuff?
I just had to have the original toybox. bought it in January, got the S2 installed in April. The wife's parents from russia stayed for 3 1/2 months and never got time to install the toybox, and now the "new improved" toybox 2.0 comes out.
I'll get around to install the original toybox and wait for a toybox 3.0 to come out.
