FPR pressure drifting
My Aeromotive FPR has picked up an extra 0.5 bar pressure since mapping and may be behind a couple of issues I'm experiencing.
Is pressure drift common on new FPRs as they get run in?
I'm also wondering if the FPR sticks slightly a every now and again the logging trace shows slips on the O2 sensor readings, yet fuel duty nor air flow change at all.
I remember during mapping that fuelling kept on shifting during idle and this was thought to be an intermittent unmetered air flow.
Is there anything to lubricate in the Aeromotive FPR, such as a shaft that connect to a diaphragm?
