if its connected to the same wire the nano reports from then it makes sense its reporting the same value.. i know thats stating the obvious but might be that simple..
No.
Nano takes it through the OBD port, how do you interrogate the LPG system?
I am just trying to help logically as I have neither.
Has your wiring been messed with much by a PO can you tell, or is it just around the LPG install?
Anybody else on here have the same issue with idle & target? got to be someone who could chime in.
