Fuel System Monitor Readiness / Flash and tunes relationship
Hello,
After driving quite a while and a number of fuelings, the fuel system readiness monitor continues to show not ready for the looming emission test. After some research, it seems a common enough issue with the 2012 Wrangler that they have a PCM flash to address it and may be required. Mine is turbo charged, so a custom tune, and I have questions that I'd love the experts to chime in about please.
Can the dealer flash the PCM with the current tune installed or will I need to drive it there, load the stock tune, have them flash the PCM and then reload the custom tune to drive off with?
And that begs some understanding on my part of what is the "dealer flash" vs tune relationship? Isn't that the same or can they flash the PCM (touching emissions parameters not affected by tunes) and then I can load HP tunes on top of that flash?
And the holy grail; is this an adjustment that I can correct in the HP tune?
Thank you for any input and looking forward to the education!
