I have several of the first "Gran Turismo" ESC's. Weren't they called "2"? (all black, first version they came out with)
I recently bought a 120A Hobbywing ver 2.1, plus a programming box. Which let me upgrade it to Speed Passing firmware. Cheap + works excellent!!!
Now, I thought I could then upgrade my old Speed Passion ESCs too... but it does not seem to be able to communicate with them. So must I then have a dedicated Speed Passion progamming box (if so, where can I buy from online?)? Or are the ESCs simply too old to be upgraded?
One of my old SP ESCs have become a bit faulty as it lacks bottom end power (slow on the straight). Could a firmware upgrade fix this or is something broken most likely?
All tips higly appreaciated! :thumbsup:
