Simon Posted December 1, 2015 Report Share Posted December 1, 2015 It is G1 Possum link.The fact there is a serial link with it is a good sign it might be PC tunable using V2.5 Pclink.There should be a sticker on the main micro giving a firmware version. Something like WRX99RIf the code is WRX99Q, R or S it is PC tunable. Quote Link to comment Share on other sites More sharing options...
