Dynamic tune ??
Hi guys ,
As I finally decided to keep my C BS after receiving my SLS BS , I'm considering the S/C upgrade.
It is clear to me that Weistec is the best option with their S3.
However , during my little research ( didn't last long with Weistec name everywhere
) I found a tuner with a S/C solution that would not affect the stock ECU... Explanations ? :
They had their own device between the S/C and the ECU that will do all the math & tune but leave the ECU completely stock.
More than that ( this is the part I'm interested in ) their device allows the driver to switch "on/off" the S/C via the Sport settings button.
"C" -> S/C off
"S+" -> S/C full power
Isn't that so cool ??
I would be all over it if Weistec had this option. This tuner says his S/C gives 680hp ( thats about the Weistec S2 power so I guess they use the same S/C)
Anyone think its possible to retrofit or adapt this thing ?

Interesting.....I wonder how they disconnect the supercharger with a switch as it's direct in a sense. Perhaps piggy back tune less aggressive....just don't know how they switch off boost per say with a supercharger.

why would you want a switch to turn the blower on and off 
if you don't want full boost , don't stomp on the pedal . when I had my Stage 3 , I could drive around at any normal driving condition in or out of traffic like a stock vehicle.....then when it was time to play , you smash the throttle and away you go .
I would think if you wanted to be stock but have power at the flick of a switch.....buy nitrous
I would like to see pricing and some sort of customer review on this thing anyway

what you are describing is called a piggy back. this is usually a terrible, last resort, cheap option. minor tuning like a change in injector size can be effectively done with a piggy back. Anything more than that and depending on how big the injector the piggy back is terrible. Pretty much a piggy back interupts the inputs to the stock ecu to "trick" them into doing what you want. It can work but is very limited. Why would you want to trick something, when you can use the very powerful and complicated tuning algorithms of the stock ecu to your benefit. what is your fear of running a tune on your ecu? Also blower on/off switch is pointless. the car already gets terrible mpg, the blower "robs" a little torque to make alot more. So when you think about that statement read it closely. Having a switch is something only necessary for emissions or maximum fuel economy which is a joke on a 63 car anyways.
So pretty much every statement you've made is a bad idea, Id tread lightly.

My thoughts exactly. You can't just turn off a S/C. It's mechanical with a belt attached to your crank pulley. The S/C pulley dictates the spin of the twin screw which the amount of air goes through the chambers. Any fuel discrepancy will make it lean or rich.

I understand mpg isn't important and that's what i was trying to get at - that emissions and fuel consumption are the only advantage of this overly complex setup. You're much better off just getting one of the turbo cars, have the tuner set up a switch for a boost controller so you can be slower or faster depending on what you're wanting. It'd be way cheaper, simpler and reliable.
