How long to reset?

[Motorhead350]

Pepboys tells me it takes a week to get everything back "on", another shop says 60 miles, another says that's all horse feathers. I am getting conflicting answers.

What is your take on how long it takes for a tune to "fully" take effect?

THANKS!!!!

:eek:

[WhatsUpDOHC]

To stock tune and passing emissions?

Gotta do the cycle.

Not return to stock, simply putting in new tune with all monitors on.

Same as returning to stock, sensors need to just get all recalibrated.

[Motorhead350]

I will give the car until monday. I do not think it needs a week.

Sound realistic? It will probably see 60 miles.

[a_d_a_m]

I think that is more than realistic.

Cold weather takes a little longer for some of the monitors to reset.

I love listening to this 'advice'. Just drive it and cross your fingers... Cold temps can prevent monitors from enabling and completing...

It's usually a combination of miles and drive cycles. You need to find out what your DMV requires.

I heard this somewhere too Dom.

It has nothing to do with the DMV when a monitor completes and sets the ready bit. It's based on specific enable conditions and time to complete a diagnostic. This is all part of the OBD calibration process. They have to run under certain conditions for robustness of the monitor. Two fully warmed up drive cycles plus an overnight soak should do the trick. This is required for the evap system check typically.

Google '2003 ford OBD system' and read the PDF. Will give you an outline on their monitor operations.

"I/M Readiness Code

The readiness function is implemented based on the J1979 format. A battery disconnection or clearing codes using a scan tool results in the various I/M readiness bits being set to a “not-ready” condition. As each non- continuous monitor completes a full diagnostic check, the I/M readiness bit associated with that monitor is set to a “ready” condition. This may take one or two driving cycles based on whether malfunctions are detected or not. The readiness bits for comprehensive component monitoring, misfire and fuel system monitoring are considered complete once all the non-continuous monitors have been evaluated. Because the evaporative system monitor requires ambient conditions between 40 and 100 oF and BARO > 22.5 " Hg (< 8,000 ft.) to run, special logic can “bypass” the running the evap monitor for purposes of clearing the evap system I/M readiness bit due to the continued presence of these extreme conditions."

I'll bet if the info was presented using sock puppets he would have full enlightenment. :D

Myehhhh.....

That was an easy read and almost too simple for me.

Of course I did stay at a Holiday Inn last night!.....:P

[NavySeabee]

Sorry if this has been asked, I didn't see it mentioned. Should you disconnect/reconnect the battery after putting back in stock tune?

I think you meant this^^^...

No you do not need to disconnect the battery putting a different tune in clears the codes in the process.
