Poll:who wants adjustable boost???

OK so if it were possible, because I am almost positive I have a way to do this, who would be interested in having a turn of a knob, no map switching, boost adjuster for their JB4/3? I am going to install on my car and collect data on my laptop shortly.

A moot point, why not ask if you want heating/cooling controls? Obvious, given the demographic target market. But I voted anyway......

Rubber, be sure to monitor exhaust gas temperature when you do your dyno study. I know you'll watch A/F ratio, and ECT, but EGT is a critical indicator of what damage couold occur. Getting the HP or Tq is a lot easier than keeping the valves from melting down.

I would if it were truly plug and play. No loose wires to solder, setup. Just plug it into the OBD slot and bang there ya go. Manage to do that and you have a large market of people who want the boosts but don't want to really mess with the car

Isn't the throttle pedal supposed to do this? Am I missing something other than a turbo and a laundry list of personal skills?

Maybe if we all get "M" buttons we'd be happier.

Hahah very true it is a dumb question, I mean its a cool idea. But I just wanted to see the level of interest before I jump into it.

I will watch it closely but I have a feeling it will run at a not so rediculous level. If it gets out of hand I wont let it get far.

Yea this would not be a simple plug and play deal, at least yet but I thought it would be a neat project if it does work.

The throttle can make it go within a pre set amount of boost values before the wastegates start to dump, whereas this would make it possible to go above and beyond current JB4 boost targets or lower the boost levels making fuel efficent driving a possibility without switching to map 8
