A:CRP919X and MK808 seem pretty similar – the price point might indicate that too, but the Launch’s ability to communicate with later CAN FD / DOIP networks would be useful.
They are both really good value but the CRP919X supports ECU coding on many car brands. The Autel does not. On Honda and Toyota you can do an ECU replacement and write the VIN number with the CRP919X. On VW/Audi/Porsche the Launch can do a lot of calibrations and coding that you would require the more expensive Autel MP808S for.
