Never had or have a smell issue. Maybe you have not got the decats completely sealed onto the manifold down pipe flange correctly.
I have zero cats. There are two primary cats only which are at the front of the car which directly come off the manifold. These have been removed. I have the original OEM cross pipe still installed as novitec and capristo said there x-pipe with decats makes it quieter. The rear OEM exhaust is still installed with only the valves wired open permanently. No need for a switchable valve box either. As I said only decats pipes installed.
OEM vs Decat pipes. I have novitec decats which have been engineered differently with a full heat wrap that comes standard with standard x-pipe. My dealer wired the valves open with OEM exhaust only made a huge difference with OEM exhaust valves being closed. The car was still not allowed enough, had a x-pipe fitted with valves open and made it quieter so returned in to OEM again with valves wired open. Still not loud enough so decatted it novitec with valves wired open on with OEM exhaust and the noise is pure F1 like a FXX or F1 car. No drone in the cabin and just perfect when open idle too. Never going back the perfect set up. Image Unavailable, Please Login
It's called Novitec Tectronic to decode the CEL light after decat or sport cat installation. It's no ECU tune only for removing the ongoing CEL. I'm sure your F12 has this feature already included in your ECU tune. Gesendet von iPhone mit Tapatalk
But if you remove the cats or change to sport cats you're reducing the back pressure and risk a slightly loss in low end torque. To get the full potential of this mod a well developed ECU tune is recommend. Gesendet von iPhone mit Tapatalk
Is there any risk that tectronic also removes the CEL light in case something unrelated to the exhaust is causing a problem?
I have no information about that and there are no technical description or sheets online. I would ask Novitec and let them send you an explanation of it. If it's the case that they are going to disable the CEL completely irrespective of the problem or malfunction which comes up, it would be a risky solution. Gesendet von iPhone mit Tapatalk
Does not eliminate the CEL completely, only makes adjustments for the ECU freaking out about no cats. The CEL works as stock with the Novitec tune other than not coming on for a couple of cat codes
Personally, I don't like gadgets connected to the OBD-II port if that's what is being used. Injecting code and stomping on error messages in a complex vehicle network with millions of lines of code executing is too much risk for me.
Actually, Fabspeed makes a miniature cat which is attached upstream from each O2 sensor, to scrub the exhaust gas that it samples. Image Unavailable, Please Login
Fabspeed advertise it "to reduce the chance of a CEL". I wouldn't pay for something that didn't guarantee a result. Will definitely reach out to Novitec when i decide to purchase the Cats and ask about the difference between that plug in device and the full tune.
Novitec is a plug in device to the OBD 3 and it does work as covered 11000 miles no issues. The fabspeed extension I have not tried and looking at them and seen the space available under the car you would have trouble with coming into contact with engine.
Novitec Sports Catalysts for the Ferrari F12 Berlinetta | Scuderia Car Parts Novitec Tectronic for Power Optimized Exhaust for the Ferrari F12 Berlinetta | Scuderia Car Parts each to there own and the system does work and brings no error messages up. All my Ferraris have been decatted and never had an issue.
no guarantee's. I would think they have a great chance of working well with sport cats...not catless downpipes.
I haven't seen an F12 cat assembly before but I have attached a diagram showing where the O2 sensors are located in the F12. Perhaps you are mistakenly referring to the pre-cat O2 sensor (#8). The Fabspeed O2 spacer is for the post-cat sensor (#9) which is located well back from the engine, probably below the passenger compartment. O2 sensors have to be accessible to allow inspection as well as replacement. Generally-speaking, the ports used by both O2 sensors are also used for the manual insertion of test probes when garages analyze exhaust temperatures as well as contents. So there has to be room available. The Fabspeed "O2 spacer" which is supposedly spec'd for the F12 and can also be inserted at various angles.
