Hi, I've tried the new poller type "ReadScaling" with no luck. First I've tried it for the BatteryManager ECU (7E5) and the voltage-PID (1E3B) which should deliver just a division by 4 as formula for the scaling: D (57865) vehicle: PollerSend(1): send [bus=1, type=24, pid=1E3B], expecting 7e5/7ed-7ed V (57865) canlog-monitor: 1599579609.443101 1T11 7E5 03 24 1e 3b 00 00 00 00 V (57875) canlog-monitor: 1599579609.453040 1R11 7ED 03 7f 24 11 aa aa aa aa D (57875) vehicle: PollerReceive[7ED]: process OBD/UDS error 24(1E3B) code=11 So 7F is "serviceNotSupportedInActiveSession" as far as I can tell. So I did swap to the Charger ECU (744) with efficiency-PID (15D6) and loss-PID (15E1) as I'm already have there a extended diag session working: EXTENDED DIAG SESSION: D (24865) vehicle: PollerSend(1): send [bus=1, type=10, pid=3], expecting 744/7ae-7ae V (24865) canlog-monitor: 1599581491.143704 1T11 744 02 10 03 00 00 00 00 00 V (24865) canlog-monitor: 1599581491.144423 1R11 7AE 06 50 03 00 32 01 f4 00 D (24865) vehicle: PollerReceive[7AE]: process OBD/UDS response 10(3) frm=0 len=4 off=0 rem=0 READING EFFICIENCY VALUE: D (24865) vehicle: PollerSend(0): send [bus=1, type=22, pid=15D6], expecting 744/7ae-7ae V (24865) canlog-monitor: 1599581491.147379 1T11 744 03 22 15 d6 00 00 00 00 V (24875) canlog-monitor: 1599581496.164030 1R11 7AE 04 62 15 d6 fe 74 09 00 D (24875) vehicle: PollerReceive[7AE]: process OBD/UDS response 22(15D6) frm=0 len=1 off=0 rem=0 TRY READ SCALING FOR EFFICIENCY: D (24875) vehicle: PollerSend(0): send [bus=1, type=24, pid=15D6], expecting 744/7ae-7ae V (24875) canlog-monitor: 1599581491.158798 1T11 744 03 24 15 d6 00 00 00 00 V (24885) canlog-monitor: 1599581491.164311 1R11 7AE 03 7f 24 11 ae 74 09 00 D (24885) vehicle: PollerReceive[7AE]: process OBD/UDS error 24(15D6) code=11 READING LOSS VALUE: D (24885) vehicle: PollerSend(0): send [bus=1, type=22, pid=15E1], expecting 744/7ae-7ae V (24885) canlog-monitor: 1599581491.165854 1T11 744 03 22 15 e1 00 00 00 00 V (24895) canlog-monitor: 1599581491.174851 1R11 7AE 04 62 15 e1 00 74 09 00 D (24895) vehicle: PollerReceive[7AE]: process OBD/UDS response 22(15E1) frm=0 len=1 off=0 rem=0 TRY READ SCALING FOR LOSS: D (24895) vehicle: PollerSend(0): send [bus=1, type=24, pid=15E1], expecting 744/7ae-7ae V (24895) canlog-monitor: 1599581491.178916 1T11 744 03 24 15 e1 00 00 00 00 V (24905) canlog-monitor: 1599581491.184240 1R11 7AE 03 7f 24 11 ae 74 09 00 D (24905) vehicle: PollerReceive[7AE]: process OBD/UDS error 24(15E1) code=11 It still says 7F :( Do I do something wrong here? Any suggestions? Thanks Soko
