I dunno, Sounds awfully like poor construction. sounds like the substrate did not have a good bond to the metal housing and over time it got loose and broke off. How many cases do we have of people's pro-cats going bad? not too many right? could just be lack of quality control? just taking a leap here. I'm not saying eshift sucks by any means. My procats have been going strong for about a year and a half even with methanol. I hope I didn't just jinx myself though.. haha
but that's awesome, they seem to be taking care of you blusap

wow even with methonal?? thats pretty good. are you tuned or just using the ACM?
your using snow performance i gather.

I'm currently using the ACM and patiently awaiting the Hondata reflash, if it ever get released to the public
yup, Snow Performance

oh man, you might be waiting for awhile
ever think about using emanage? whats nice is you can always get it retuned and boomslang now makes a PnP harness for the TL. just a thought, cause i know how bad the surging is with the ACM. i only used it for a couple of days and it drove me nuts =P

Ok now here is my turn to chime in right quick, and don't think I am in a rush to polute the environment but what would be the benefits of running 0 cell cats/ gutted all 3 cats?
For inspection purposes I can probably get around it (cough cough)

Blusap - sent you a pm about tuning
you may pass visual, but you aren't going to pass the actual test.

Yes, but it is colder to start with...the richness INPUTS heat at a high rate unitl operating temp is reached. The mixture levels out once operating temps are attained. ULEV cars do not overheat cats. They just heat them up quicker providing better cold start emissions. ULEV cats may be able to handle higher temps (MAYBE), but we are not talking about worlds of difference here.
No, this is not true. ULEV cars do not run at signifcantly higher EGT levels to warrant a "special super cat." The cats are different because they have more cells and remove more pollutants from the air. Not because they can withstand higher heat.

Hey Blusap, when you removed the cat. Did you shake it lightly? feel the substrate bouncing around in there?

I don't understand why you wouldn't pass emissions. The first two cats to the great majority of the work. The 3rd cat has no O2 sensors and won't throw a CEL.
The emission standard isn't vehicle specific, is it? If not, your car just needs to clean the exhaust as good as a "regular" non-ULEV car right?

While I don't know the compostion or specific chemical function of the catalytic substrates, I don't doubt for a moment that they have some precious metal content.
I'd guess Palladium, Platinum, Iridium and/or Gold - could be others, but I'd think those are the most likely. Reason is these metal are pretty non-reactive and will "hold up" to the catalytic reaction that occurs in the cats for a long period of time. They *might* be part of the catalyst in the catalytic process as well.
A Catalyst, chemically, is a substance that is involved in a chemical reaction and enables that chemical reaction can occur at lower energy. When the reaction is concluded, the Catalyst itself is unchanged.

If that occured, I suppose it could impede the catalytic function.

Good guess on the precious metals, but they are not part of the substrate themselves. The substrate is just a metal or ceramic matrix and serves as a base for the catalytic washcoating that contains the precious metals. The metals themselves actually are relatively active.

The ceramic substrate was invented by Rodney Bagley, Irwin Lachman and Ronald Lewis at Corning Glass for which they were inducted into the National Inventors Hall of Fame in 2002.
2. The washcoat. In an effort to make converters more efficient, a washcoat is utilized, most often a mixture of silica and alumina. The washcoat, when added to the core, forms a rough, irregular surface which has a far greater surface area than the flat core surfaces, which is desirable to give the converter core a larger surface area, and therefore more places for active precious metal sites. The catalyst is added to the washcoat (in suspension) before application to the core.
3. The catalyst itself is most often a precious metal. Platinum is the most active catalyst and is widely used. However, it is not suitable for all applications because of unwanted additional reactions and/or cost. Palladium and rhodium are two other precious metals that are used. Platinum and rhodium are used as a reduction catalyst, while platinum and palladium are used as an oxidization catalyst. Cerium, iron, manganese and nickel are also used, though each has its own limitations. Nickel is not legal for use in the European Union (due to reaction with carbon monoxide). While copper can be used, its use is illegal in North America due to the formation of dioxin.

If the substrate is the "support for the catalyst" is the physical internal structure of the cat. If the cat breaks, it is because the substrate failed.
The precious metals are the catalyst, and it is only present in the form of a suspension in a fluid that is poured over the catalyst. A ULEV car simply has more surface area on the substrate (through the use of more cells per inch) for the catalyst washcoat to stick to.
Saying that the core's inability to withstand a ULEV car's exhaust is like saying a car's body would not be able to stand up to the sun if it has a poor paint job. In other words, a cheap paint job may last longer than an expensive one, but neither one is going to result in a dented fender. The fender is just the substrate for the paint. To damage the fender, you need to hit the car or add a lot more heat that the sunshine is going to provide. You'd need a torch or something to melt the fender.
Similarly, to break the catalyst, it is going to take more than a change in temperature. Below a certain excessive limit, a ULEV exhaust is not volatile enough to damage a cat. In all likelihood, the exhaust on a low emissions car is probably cleaner than on a non-ulev car.

would the emange make any difference on a N/A TL? Would significant gains be made by just tuning?

Well, in washington it is car specific, even down to the year.
I'm pretty sure he's talking about gutting ALL cats. Which would basically be like running a a straight pipe from the head.

You DO realize that wikipedia isn't REALLY a viable reference, right? Not like it's all actual FACT. Some of it "may" be fact, but in other cases, it's been shown to be little more than fabrication by the author. So, by referencing wiki as your source you are basically saying.... I don't have a REAL authentic source so I'll share a "common opinion" and alude that it is in fact, verifiable.

Super heating can cause damage to any cat. And that is why if the exhaust is being super heated it is going to cause a problem. The stance some are making is that on some cars the cat is super heated during cold start. While I agree that extra heat is put in, it is only to compensate when the cat is cold. Therefore, adding more heat does not mean the same as overheating. Overheating is different.
Guys, what about ULEV is making it such a big concern? All it is is a bigger cat and more evap crap.

I am very hesitant to post anything regarding this matter having no specific info and not being responsible for this product. A lot of money and folks are involved and it's a bad situation for all the parties. I'm sure Mike will chime in when he has some concrete solution, that would be the best. He does his best to answer the phone on regular basis even while working on cars, he does not seat in the office all day by the phone and PC, more often he's in the garage wrenching or working with his walk-in clientèle.
I can only say that the last time we spoke about this he acknowledged the problem and told me that all the shrunk and damaged cats are going back to the manufacturer for inspection. Quite possibly this is a manufacturer defect, in some cases the cat material shrinks up to the point where it can no longer filter spent gases and that's when the O2 sensor communicates a problem to the ECU and it throws a CEL.
Mike was also commenting on the close coupled primaries and that they endure extreme high temps, especially in a supercharged application and more so with HBP. Obviously this is Honda's emission, weight saving and packaging solution but it does not help the pro cat longevity. He offered to experiment on my car in relocating the primaries further downstream from the head, extending the O2 sensors, etc.
If anyone has absolutely no luck getting a hold of Mike or Wayne, PM me and I will try to pass the info on to them or help you catch up with them somehow. I'm working on my car in their garage now so I see them almost every day. Hope this helps!
PS. I'm sure this is a well known info by now but I'll cite it again just in case. This comes from the Acura press releases on the TL emissions and tech specs.

So, I was curious to see what my cats looked like after about 15k miles with S/C and Methanol. (a little over a 1.5 years)
I haven't had any problems or noticed anything wrong, just curious.
I took off my jpipe and looked at all 3 cats. my 3rd cats is in perfect shape, nothing loose inside.
I looked at the front 2 cats and it seems the substrate is loose, can move them up and down with my finger, but nothing is seems to be "deteriorating." I took a pretty hard look at it and it seems there was some kind of glue or epoxy type thing that holds the substrate to the walls of the cats. These failed to hold the substrate, thus the free movement of the substrate. By design it looks as if the cats are still doing their job because they are still in a position where it would burn the hydrocarbons and let air flow through.
again, the cats look absolutely fine the only thing that failed is the adhesive that held the substrate in place, but since the substrate is bigger than the openings, it doesn't look like it would do much harm.

I took a pretty hard look at it and it seems there was some kind of glue or epoxy type thing that holds the substrate to the walls of the cats. These failed to hold the substrate, thus the free movement of the substrate. By design it looks as if the cats are still doing their job because they are still in a position where it would burn the hydrocarbons and let air flow through.
again, the cats look absolutely fine the only thing that failed is the adhesive that held the substrate in place, but since the substrate is bigger than the openings, it doesn't look like it would do much harm.

im definetly going to be calling you soon, regarding those brake kits we talked about. my powerslots are starting to get heat cracks

you would think that a co. as well known as eshift, can at the very least return a call. im starting to get a feel on how they do business. customer service was great when purchasing, but when i comes to backing their product, its a whole different story. you either get the major runaround or totally ignored altogether >:-(

Is there any NA people around experiencing the same problem? Can anyone else speak up? Would doing a smog test be the best way to diagnose this problem? I really don't want to take everything apart.
Josh, what's your take on this?
04accord, have you tried contacting Excelerate on this? He is the sole distributor, right?
