Hi guys, advice needed as am new to tuning. Currently running cobb stage 1 ots map with roush intake, roush cat back, cobb rmm.

Just came into a good deal and am getting a CPE FMIC and a cobb catless DP. When install the fmic I know I can load the cobb ots stage 2 tune, when I install the cobb catless DP am I good to run the cobb stage 3 ots tune over the winter? Will the catless DP give me any issues or throw a CEL?

Thank you in advance, also if anyone has a Roush CBE and COBB catless DP video please post or link it

You will indeed be able to run the stage 3 tune.

Thank you, I was curious if the tune was designed for a catted or catless, or wide enough to encompass both. Should I expect a CEL from the catless?

The OTS tune on my '13 with catless DP did not turn off the rear o2 so I got the CEL.

Difference between catless and catted, is airflow.

You sure its a Cobb catless?...

 

[MiSTify]

Yea Cobb doesn't make a catless DP, at least for the ST they dont

MRBP dont know why I typed Cobb

You might need to buy a defouler... some dont and some do it is strange how these cars react differently to mods and tunes.

I have the COBB OTS stage 3 tune and been running it with Levels catless downpipe for the whole summer with 0 issues, out 6k on the car during that time. I am running a defouler on the downstream O2. never had a CEL and all sensors are at ready. COBB OTS can handle the catless but i would still recommend getting a "pro" tune down the road if you really want power.

could have spent $8 on a defouler and fixed that... I recommend that over a tuner turning off sensors.

This was close to 2 years ago.
I lived in FL with no emissions. I didn't care. I had an MBRP Noncat DP. Even when I moved to TN, I swapped over to a Cobb DP, I still got a CEL with custom tune. I did have to buy the defouler for that though.


Telling me what could have done 2 years ago is kinda pointless

Yet you posted this yesterday... NOT 2 years ago AND it is still VERY relevant to the OP so he gets good information when building his car.

Don't know why you are taking it as a personal attack?

I wasn't telling you anything BTW I was providing information. I have installed 6 DPs in 6 different cars all of which were a different variant of DP and model year car.

I find it strange you "didn't care" to have a CEL on and didn't want to fix it, readiness codes are there for a reason. car will run better with them at "ready status", emissions aside, because I honestly don't care for emissions or I wouldn't be running catless

 

[MiSTify]

I didn't say I had a CEL on and didn't care. I said I didn't care it (the Rear O2) was turned off by a tune.

And I did post.. years ago. But since yove only been a member here for a year you wouldnt know that. The question was always does the Cobb Stage 3 tune turn off the rear O2. My post was relevant as, no it doesn't turn it off and you will get a code running a Catless DP. Unless you get the defouler of course.

And if you aren't directly replying to me then don't quote me.. that's what quoting people is for.

What is the defouler, where should I buy?

what a Google and how do I use it?
Let me google that for you


This is what I did and it worked for the last 3: total of $8 i think

Where can one acquire these defoulers?

NAPA, Autozone... you name the auto store I am sure they carry it

Or go on to Amazon and get the J-type it had adjust-ability

Do yourself a favor and get a custom tune from a tuner you can trust and communicate with. They will answer all of these questions and you will make more power that's safer for your engine.

I've gone through all of the hoops with tuning and lived in ignition correction hell for months. Once I was pro tuned the car ran better than ever... And Wala! No more negative corrections.

Get a lifetime tune if it's offered so you can add more parts down the road. Most importantly do your research before pulling the trigger.
