Thanks Dave. Couple more questions, hopefully the last for a bit. One, I read something in the Onraod thread a few weeks ago about having to flash software twice to either the box or speedo to get it to work. Is that correct?

Two, any recommendations on what SP software to flash to my HW speedo in 4wd buggy? XERun V2, 6.5 motor with 40C batteries. No boost or turbo needed
