I don't think they are actually doing anything because I never had a catalyst low efficiency DTC pop up when I was running the old O2s and high flow cats but I never took them off to check. BTW one thing I did forget to mention is I installed a set of these O2 sims (even though I am running high flow cats) on the downstreams the same time I replaced the O2s.
#2012 jeep wrangler fuel system monitor not ready mod
I was hoping the pros might have jumped in to give a hint as to what they do to get the monitors to complete but I guess each car and mod is different. I forgot the percentage but these are the deltas(current tune compared to stock).
I know this is sounding like an old record (wish I had other suggestions for a solution) but swapping the O2 sensors with new ones and reverting the engine diagnostics back to stock was what did it for me.transport delay had no effect but worth a shot I guess.īTW my O2 sensor parameters in the tune are also stockĮxcept for the transport delays. Below is a screenshot of the slow to respond O2 I was fighting. It was always the O2 sensor and catalyst that would not complete for me and hence the fuel system monitor did not complete. I don't see how the O2 monitors (at least the catalyst and O2 sensor) complete with a P113 or slow to respond O2?
