They pretty much all have a mini USB part and cap covering the port to keep debris out. Some caps will blend in so give it another look! Its there, although I've never touched that product so.... But it should be there!
Interesting, that model looks like it's not for race and it may be under C.A.R.B. which is the California Air Resources Board. Power Commander has an EX model( a different brand/co.) where there is a limited range of programming. This C.A.R.B. compliant Juice Box might be the unit you have. It may not be adjustable other than a limited range of fuel control from the user interface. This would keep the controller C.A.R.B. compliant.
