Reset catalytic and evap monitor

Just another Marauder owner
Hey guys
So I took the Marauder into the Smog shop in California and was told no go. Apparently the Zack tune (Awesome tune) turned off a few monitors that are now checked by California. I have been able to get all monitors reset except the Catalytic and the Evap. How do I go about doing that? I have put 200 miles (varied terrain, speed, throttle) on her since returning her to stock tune, which has its own challenges - stock = 3.55, but the car has 4.10's ... speedo is kinda off.
Thanks!
 
Watching as I'm having the same exact issue! Evap won't reset no matter what I do.

It just takes driving the car. Sometimes 400-500 miles. I changed my tune a month before I took in into smog. Second monitor turned on. Passed.
Changed tune back to Marty’s tune.

Thanks ... will keep driving her ... I had two different folks who wanted to buy in California, but the smog not done is preventing that. Ugh, I hate the California Smog rules ...
 
They changed the smog rules 3 years ago because people like us would change the tune, get 1 monitor to turn on and then pass. That’s why the change to 2 monitors have to be on.

For the cat monitor you should try using your cruise control as it is VERY picky about speed. This is in regards to holding a certain speed for ten minutes at speeds between 25-45 repeated 5 times at different speeds.

Between all five speeds you must also come to a complete stop and for the next run you need to get up to speed using only 1/4 - 1/2 throttle. You should try and pick a road with a 45 MPH limit that’s not busy with a shoulder to pull off onto, or even a highway at night. Your speeds can literally be 40/41/42/43/44.

Having a scanner hooked up to verify when complete definitely helps.

Also make sure your fuel tank has over 15% of fuel or the PCM suspends all testing.

This worked on my F150 when it pretty much refused to reset the cat monitor, common on most Fords.

As for the EVAP, I thought even Cali followed EPA guidelines like ALL states with emissions in that they do not require that monitor to be ready? On and not ready should pass, turned off would be a fail..

PS I can’t recall but is there a way to alter tire revolutions per minute on a stock tune? Doubtful but would help with the shifting and the 4.10’s.

I drive my car for about 10 minutes at different speeds, mostly under 40mph as I just putt around on local roads. I was told to the secret to the evap monitor is that it needs to sit for a long time after the car is turned off. I let it sit overnight after my short jaunt and haven't had a problem.
 
My EVAP finally went ready. Turns out it has been too hot. According to http://www.obdii.com/drivecycleford.html IAT has to be between 40F-100F. It has been so hot lately and the design of the Reinhart "airbox" apparently doesn't do a great job of keeping hot engine bay air out. By the time the coolant was up to the temp range the IAT had already exceeded the range.

I drove it early in the morning a couple days ago when it was in the 60s and it completed the required test after only about 15 minutes of driving. Hardest part was getting what that site calls EVAPDC but what Forscan calls EVAPVM to stay above 85% as required. Finally found a long, uphill stretch of highway where I could stay under 65mph but stay on the throttle at least a tiny bit so that the duty cycle got high enough. Forscan showed that the test had completed. Turned it off and let it sit overnight, turned it back on and the monitor was ready.

Cat still isn't ready, but GA allows 1 not ready for a car of this age.

[TD][h=3]Ford Motor Company Driving Cycle[/h]Description of OBDII Drive Cycle
The following procedure is designed to execute and complete the OBDII monitors and to clear the Ford P1000, I/M readiness code. To complete a specific monitor for repair verification, follow steps 1 through 4, then continue with the step described by the appropriate monitor found under the "OBDII Monitor Exercised" column. When the ambient air temperature is outside 4.4 to 37.8°C (40 to 100° F), or the altitude is above 2438 meters (8000 feet), the EVAP monitor will not run. If the P1000 code must be cleared in these conditions, the PCM must detect them once (twice on some applications) before the EVAP monitor can be "bypassed" and the P1000 cleared. The Evap "bypassing" procedure is described in the following drive cycle.
The OBDII Drive Cycle will be performed using a scan tool. Consult the instruction manual for each described function. NOTE: A detailed description of a Powertrain Control Module (PCM) Reset is found in this section, refer to the table of contents.
Drive Cycle Recommendations:

  1. Most OBDII monitors will complete more readily using a "steady foot" driving style during cruise or acceleration modes. Operating the throttle in a "smooth" fashion will minimize the time required for monitor completion.
  2. Fuel tank level should be between 1/2 and 3/4 fill with 3/4 fill being the most desirable.
  3. The Evaporative Monitor can only operate during the first 30 minutes of engine operation. When executing the procedure for this monitor, stay in part throttle mode and drive in a smooth fashion to minimize "fuel slosh".
WARNING
STRICT OBSERVANCE OF POSTED SPEED LIMITS AND ATTENTION TO DRIVING CONDITIONS ARE MANDATORY WHEN PROCEEDING THROUGH THE FOLLOWING DRIVE CYCLES.
For best results, follow each of the following steps as accurately as possible:
