this ^^ is perfect but if you buy MX+ you can use that on any modern car plus it will allow to use both Android and apple phones with it.
While trying really really hard to figure out ABS not bleeding with Tuneecu and 'dealertool aftermarket software; I found a free software,( dont remember name anymore) which is sitting somewhere on one of my other computers, that Free windows software supports this Trumph ECU and can read all the data from new 2020 rocket including freeze frame, delete codes etc. but you need an USB OBD cable and any old/new laptop for it, Rocket 2020 OBD cables are like $20 or $30, I have to dig in to computer to find that software but I am just too lazy because I already have both aftermarket tools on the market for doing basic stuff on the bike.
It could be helpful for people who dont want to buy tuneecu license + new tablet + OBD MX+ and just want cheapest solution possible with a basic OBDII usb cable.
100%, hard to speculate without codes.
