looking at the data logger my map reading is 15 psi without being on and drops to 4 psi at idle. It doesnt even go into the negs. would that indicate a high resistance or faulty map sensor? could someone please tell me what data values i should be expecting and what pids i could bring up. i tried to find map volts but no such luck

thanks

thats normal, 15 psi is atmospheric pressure, it drops when there is vacuum in the manifold...

thanks mate.
Ill have to keep looking
