In the Focus ST community many people run a defouler on the second O2 sensor to keep it out of the direct stream of the exhaust.

This helps the car not throw codes yet allows the sensor to become ready when running no tune.

Option one: https://www.modernperformance.com/product/Vibrant_Oxygen_Sensor_Defouler/caliber_exhaust

Option two: http://www.2j-racing.com/fiesta-st/2jr-fiesta-st-downpipe-de-fouler.html
Will those retrofit to the Fiesta ST? EDIT: Nevermind, I ordered one. [:)]

All my I/M monitors show "ready" except my evap (I'm almost out of gas). I'll put about 8 gallons of gas in and try to redo the inspection sometime this week. I've driven about 100 miles and have had no codes or CELs since uploading version 2.20.

I guess I'll try a defouler if it fails again but I'm not sure what happens with a subsequent (or second) I/M test failure.

Which evap? the evap system? If so, I know how to make it ready at least what's worked for me.

Just put gas in the car but don't completely fill it up?

that's one part of it [coolsmile]

Here's what's worked for me to get a ready state for the "evap system" monitor.

- fuel tank half full.
- flat highway, no hills or wavy roads. the key is to keep the gas from sloshing around in the tank.
- set cruise control at 55-60mph and cruise for 5-7 miles. limit use of brakes preferably not at all to keep fuel stable in the tank. If you need to speed up or slow down use the (+-) cruise control buttons.

that should do it.

It may take several attempts depending on if the ECU parameters are met to run it's tests.

Thanks, I'll try that!

Not working for me. I've driven about 100 miles this way now and can't seem to get the evap system to ready state. When I failed the first test it was "ready" but the cat, cat sensor and cat htr wasn't. lol. I'm wondering if it will still pass the I/M test with the evap sys not ready. All my other modes are in "ready" state.

That was the hardest monitor for me to get ready, I think that's the only monitor that is allowed to not be ready and still be able to pass. Here in CA we can go in for a 'pre-inspection' for a small fee to make sure the car is ready before going in for the real inspection and not be dinged and recorded. Anything recorded lives forever with the car's VIN IIRC.

So, I still can't get my EVAP SYS to show "ready" and the inspection station tech says it MUST show "ready" to pass inspection. Also despite the Cobb AP I/M readiness status stating my catalytic is in "ready" state, the inspection station says it is not. Tale of two stories. I'd like to know why the Cobb AP shows everything in "ready" state (except the evap) but when the guys at the inspection station plug in their OBD I/M tester it shows the cat as being not ready. This is BEYOND frustrating. No way to register my car without an inspection and it appears that the only way at this point I can get it inspected is to go completely back to stock. I'm beginning to regret modifying this car past stage 1. The "maintenence" required to keep it in compliance is not worth the hassle (R&R the downpipe every year so it will pass inspection). If I must put the stock DP back on, it is staying on. [rant]

You can try removing the tune and go back to the stock tune, add a gallon or two of e85 and try to get all of the monitors ready again. I think the check engine light doesn't come on for around ~60 miles for the highflow cat, but with a little e85 in the mix it may extend that. Ideally you'd want to be able to get all monitors ready and car inspected before the check engine light appears.

Ideally you'd want to be able to get all monitors ready and car inspected before the check engine light appears.
I tried this method this morning (running the stage 0 map) but I did not use a mix of E85. My understanding of how the cat/rear 02 sensor works is that it reads flow (in voltage). The less restrictive the cat is, the higher the voltage. If it's under or over the prescribed voltage requirements it will throw a cat efficiency CEL. Unfortunately for me, the CODE for cat efficiency shows up DURING the ecu learning (BEFORE I even get a CEL). This means the cat will never show as "ready" BEFORE I throw the CEL. This was in the first 20-25 miles. Even if I get a CEL, I can't just clear the code... the AP also clears the "learning" as well, so I have to start over with getting everything ready again. I'm going to try a 2JR defouler. If that doesn't work then I'll be forced to pay someone to put the stock DP back on. I don't think I will be able to convince myself to go back to stage 3 again. You'd think there would be other "easier" solutions to this issue (like in the past we could use resistors with the o2 sensors to alter the voltage output) but other than the two defoulers mentioned earlier in this thread, I know of no other credible solution for those with high flow catted down pipes.

What erks me is that the Cobb AP showed everything "ready" except the evaporator system (which won't change to "ready" status no matter what I do), but when I get to the inspection station they show the catalytic as "not ready" on their handheld OBD scanner. Fortunately, I had them run a scan BEFORE I attempted to have it inspected. All systems MUST show ready to get a pass here, even the evap.

Not sure why the discrepancy. Kind of curious myself if the results would be consistent with other I/M status readers.

To add insult to injury, I can't get a *PERSONAL* reply to my email(s) from the Cobb (Plano, Tx) location whom I have dealt with directly with more than satisfactory results up to this point (or Cobb (Austin, Tx) location unless I am actually buying something). I sent the Plano, Tx location an email on November 30th and never got a reply (and again last night) and all I could get out of Cobb (Austin, Tx) was a message in the open forums.

In the past, when I wanted to purchase something and/or schedule an install, I've heard back from them within a few minutes to a couple hours at the most. I realize they are probably very busy before the holidays, but I'm a customer who bought every single part they have available for this platform (sans exhaust and a shift knob...) and even had them do some maintenence (changed the trans fluid to Motul). I've spent a TON of money with Cobb (since 2001 on several different vehicles; dating back to when Trey was local), you'd think the least they could do is schedule me in to have a defouler installed. I understand they aren't going to make alot of money doing this and it may seem low priority but... I can't get my car inspected (or even registered) until I do something about this issue. Swapping out the DP is a last resort solution, however if it comes to that then the stock DP will have to stay on the car.

I bet you if I contacted Cobb to pay them to remove all their parts (labor) then purhaps they would send me a reply and schedule me in. lol I'm just about there. [:(]

I started a new job so I'm really not available to talk by phone during business hours, otherwise I'd be blowing up their phone! [:p]

Just verified on my Stage 3 Fiesta ST running the latest OTS map that EVAP SYS shows READY with both the AP and a generic code reader. Therefore, you might have an actual leak in your system causing the not ready state. No idea about the station reading the catalyst as not ready. All our testing on different devices shows the generic OBDII code reads properly. Have they given you a print out you could post up?

Thanks for the reply Ian. I have an appointment with Cobb Plano on Tuesday morning. I'll know more then and I'll post up any new info then. [:)]

I reset the ecu learning yesterday and I guess all the stars are aligned because everything on the I/M status shows "ready" after just 20 miles. I'll put 100 miles on the car and then get it inspected.
