Original KESS V2 ecu tuning tool by Alientech. This is a second hand unit slaved to a master tuner, I’ve not used it myself as I bought as part of a deal with other kit but I believe it is with regal tuning? I can’t be certain though, you’d have to check with the software or get your Mayer tuner to reset it to them. Only selling due to having too many other things to deal with atm. Thanks for looking.
