Fabspeed Header problems

when you say "the oxygen sensors had to be adjusted so the computer would sense the same amount of oxygen" do you mean you installed 02 extenders??
I just installed the fabspeed headers and I picked up my car yesterday, after 50 miles of driving the car I got a CEL but it doesnt worry me because if you perform a search about the topic is a WELL know issue a CEL could be triggered and the way to fix this is:
1) regular 02 extenders (this is a hit and miss)
2) mini cat 02 extenders (this one supposedly resolves the whole thing for good)
3) tune (this one for sure fixes everything)

I do not think it is fair to trash the headers when it is (as I said) a well known issue the consequences of installing them.

 

It might be related, because as I said the universal 02 extenders are a hit and miss solution.
Try the mini cat 02 extenders now and see if that fixes the problem, Fabspeed makes them.

Some members had the big daddies installed, but do not hold your breath trying to get some support or customer service from those guys, they do not have a number, only an email and they are the worst to deal with.

Which codes are you getting? P042x and/or P043x???

 

I am no fan of Fabspeed, but they do have a contact phone #, and I suspect, do answer their phone.

If this is a known issue, perhaps they have a workaround. Have you spoken with them about this issue?

888-646-4945

or

155 Commerce Drive
Fort Washington, PA 19034
P: 1.215.646.4945 | F: 1.215.646.9828

I have never known them to run from a conversation, even when that conversation isn't always pleasant.

I was referring to Bigdaddies not Fabspeed.

I'm not sure why you say it's not related to 02 sensors. You are resetting the ECU's which resets all the monitors. They run again a few times after you start running the car again. The ECU then detects the cat efficiency to be out of range and sets mode 6 codes that you can't see or set an efficiency CEL.

 

When did I say "it is not related to the 02 sensors"?
Of course it is related to them, that is the WELL known issue when you replace headers.
If you read my posts again I told you the 02 extenders are the first step in the troubleshooting process, it didn't work so now you need to go to th second step that is mini cats extenders instead of regular extenders.
If that doesn't work supposedly the next step is a tune.
Why don't you call Fabspeed and express your concerns to them?

 

Couple things.

1. feralc Chill a little. OP is struggling with a problem, you don't need to get extra defensive. Between his last post and mine, you seem a little, well, edgy and defensive. Maybe a nice Sunday drive will help you relax a bit.
2. OP>>> This. "Why don't you call Fabspeed and express your concerns to them?" It's their crap you're struggling with, I'm willing to bet you're not the 1st customer to have this issue, and maybe they have a solution.

 

When I had the CEL come on, I called the Ferrari dealership and they recommended the exact same procedure mentioned by Feralc, my next call was to Travis at Fabspeed, their customer service was amazing and YES they have seen this problem before. Travis immediately advised that he will be sending me the mini cat O2 extenders as this should take care of the problem; should that solution fail then they will ask me to sent them the ECU for a tune. Throughout this whole process I found Fabspeed to provide an amazing and prompt service. I am not worried or concerned based on the Fabspeed team's performance so far. I will provide an update once I implement the second step remedy. Happy Sunday driving to all.

 

If it has a cel it must have a code/codes, what are they?

 

Maybe, I must apologize if I sounded edgy and defensive, i will take your advice and go for a nice Sunday drive.
I have no affiliation with Fabspeed but I think is unfair to trash one of their products without doing the necessary due diligence about what could happen, Fchat is a great source of information and even mechanics come here from time to time when they can't find a solution.
After years of coming to this forum I have found that members don't really like when a topic is restarted when it has been discussed dozens or hundreds of times, most of the time those threads don't have replies "a simple search and you will find...." is usually the response.
I try to respond (if I know) even in those topics to save the OP time and effort, I tried to do the same thing here and I felt like my advice was "questioned"
Chris: I am sorry I hope you fix your car soon

CEL = fault codes. Unusual that your CEL shows no codes.
I got cat inefficiency codes every time I drove after fitting headers. Extenders fitted and seem to be working for me.

 

The issues and resulting problems are very common when the original headers, which had pre-cats in them, are replaced with ones without.

 

Are you checking both ECUs? The first CEL I had showed no codes on the first ECU, I had to switch to the other ECU and I found it, most generic scanners will not see the second ECU, what is your mechanic using?

 

Is this in any way related to the fact that factory 430 headers have precats and most aftermarket units don't?

 

These cars are quirky, it is risky living with these cars in an area where there is no dealer and/or someone with the proper computers and know how to play with them.

 

The easiest way to resolve an O2 error is reprogramming the ecu.

What tool are you using to get to the error, I've not seen a CEL light and no errors. Something set it off, if ur tools isn't telling you where to look your just chasing you tale.

 

OK. I have installed the fabspeed headers recently as well but do not experience CEL issue (Yet / Knock on Wood)

This is totally different from O2 sensors or extenders that came with the headers.
My mechanic told me he wouldn't use the gaskets that came with the product where he used the OEM. Maybe that could be the problem?? I don't know but that is what my mechanic did due to his experience with aftermarket headers especially Fabspeed. I have Fabspeed products all over and have never ran into one so far. I even have a Resonator Bypass X Pipe on my Audi S8 and it sounds incredible.. They make good products in my experience.

It maybe nothing but check with your mechanic what gasket he used.

 

lethetton. Calling Fabspeed is a good suggestion. Foreign Cars Italia is authorized Ferrari dealer with a Charlotte and Greensboro location. The NC Chapter of FCA has several members who live out near you. Why not post in the North Carolina section for local mechanic referrals?

 

The additional part are not the mini cat extenders? Because that part fixed my CEL and it has been around for a while now
