need help to config my ELM ADX file for request Fuel Rail Pressure parameter in Service 01 PID 6D
this note is correct ?
send command
Hex cmd string : 0x4D 0x30 0x31 0x50 0x30 0x44 0x53 0x30 0x36 0x52 0x31
ASCII string: M01P0DS06R1
listen Packet
Packet Type: Static Packet size
timeout: 400 ms Payload offset (Dec): 0
Body Size (Dec): 6 Payload offset Size (Dec): 6
68BF this is 2 bytes (hex) value that I get from data list on tunerpro it's not correct
I don't know where did he get it from ? actually should be 1B0D or AC00 like that
just still confused with bytes returned 6 or 11 bytes?
see Wiki link or SAE J1979-DA OTC2011 documents
https://en.wikipedia.org/wiki/OBD-II_PIDs
at the same time this is true data response on port terminal
when I sent 016D via AT Commands
41 6D 1B 0D AC 00 3D 00 0D AC 00 45 00
"1B 0D AC 00 3D 00 0D AC 00 45 00"
1B Support info.
0D AC Target Pressure Value (A) 00 3D Actual Pressure Value (A)
0D AC Target Pressure Value (B) 00 45 Actual Pressure Value (B)
for Both light 00 = fuel temp. is not support for this model
convert hex to decimal like 0D AC Target Pressure Value (A)
(H) 0D AC = (D) 13 172 and import to formula " FRP (kPa) = ((13*256)+172)*10 "
= 35000 kPa yes that's true! for fuel pressure target value
my question How can I start offset ADX for reading fuel press value from this point?
Any advice on this topic is greatly appreciated
Many thanks for considering my request.

Hi
Noticed your looking for PID 6D but in your setup you have PID 0D this may be your problem
Cheers
