Right now, I will only install them in house. Like I said, very complicated installation.
It mounts to the torque tube.
If you already have an Eboost, 650$ gets the switch plate, harness, relays, installed, and setup for you ready to go.

Does anybody out there know how many different settings that are for an E-boost 2 on a TT set up? In an ideal world I would want one setting for low boost where every gear stays at 7 psi; I would want one setting for every gear to be in high boost like 15 psi; and I would also want a boost by gear mode. I would almost be fine with the default setting be boost by gear, as long as there is a manual override where I can chose a specific psi to fit my different street desires. Does anybody know if an E-boost can do that or if it is always in boost by gear mode?

[QUOTE=jrubicon;1573817961]Boost by gear has been working fantastic for me. Power can be put to the ground in every gear (1st is still a little touchy )
Just saw you live in Charlotte...would love to see your Boost by Gear setup in person as I already have the Eboost controller configured by RPM. Interested in determining the cost vs. benefit of adding this.
You going to the next Cars and Coffee?

I have a new solution for the guys wanting boost by gear. MUCH simpler to install, more of a MPH related system, however, still switches within a given MPH window for the EBoost 2.
Oh, its a 1/3 the price, and takes 1/2 as much time to install
The problem with the plate on the torque tube, is that it will fail. There is no room in there for the switch plate, so one instance of axle hop, and it will break a switch. It might not do it the first few times, but they will fail. There is simply not enough room.
My new system is mph based, switching the grounds for the Eboost, within each gear window. Pretty neat.
The other issue that I ran into with the actual gear based system- Say you set the car into spin- Naturally, a good wheel man would short shift to the next gear. However, with the old setup, it would toss you into the next higher boost window, causing more spin.
Now, you can set SP 1-4 to an actual MPH.

I am having trouble with the switch plate on the tq tube, need a new solution! Let me know what you have to offer

Sounds interesting. Makes me think it would be neat to control duty cycle based off front/rear wheel speed difference. If you could adjust the gain vs % slip you could have some serious traction control ability.

I can do that. Im fortunate to have some very talented electrical engineers that work with me and are truly passionate about what we do.

Then adjusting gain vs slip if a fixed constant or similar, will work only in a given range.
A practical example would be a heating control loop for say a 5000 gallon tank. You have the control loop dialed in (PID loop gains) at 80% full (4000 gallons). Then you fill to 2000 gallons and notice you get a huge overshoot. This is normal for simple or a classic PID loop equation...
The reason I brought above example up is, if you got it working pretty well in say 2nd gear, by 4th gear it would likely not be sensitive enough (do to lower rate of change - ie speed delta rise of front tire vs rear). It's like hitting a constantly changing target, which it is.
Not saying it can't be done, just saying it's beyond the control algorithms found in off the shelf boost controller.
