Are you freakin' kidding me? Not that I doubt what you are saying... but if that is true, then WTF is going on? They have been putting CATs on since about 1975 and you mean to tell me that almost 35 years later that they can not make something that simple last on a computer controlled AF mixture.

Any insight appreciated. I really want to get this beast paid off before dropping dimes on this kind of crap.

the only high flow cat you going to get is if you talk to d3 on there shorty headers because the cat on this car is part of the exaust manafold

Wasn't one of the selling points for the W4M tune , the reprogram was done in such a manner that it was hidden from the view of the dealer?
I now have a check engine light which leaves a code of ,Too Rich injector flow, and bad Cats.
I sent W4M my original ECM to get the Remote Start to function and not do the Relearn .
Do I have to worry about the tune showing up now?

Two people with the W4M tune that now have bad cats? This worries me. Can some others weight in?

sorry guys I havent had time ot bring the car in this past week. I'll do it tomorrow and let you all know.

Well lemme tell ya, Ive had these codes for the better part of 12000 miles now, the dealer tells me to replace the cats and to bring him 1900.00 but heres the thing, it isnt the cats, I have read forums till im blue in the face, if your car will get to 70 mph without hesitation it isnt the cats, My 1sg is throwin p0420 and p0430 codez I can clear em all day long for a half a day and they will still come back in about 10 miles, number 2, the O2 sensors, dealer swapped the O2 sensors, diagnostics showed them bouncin up and down so in this case it wasnt the sensors either, number 3 the MA sensor, well here was another bust, cleaned it, replaced it and still p0420 and p0430 and no remote start, well anyways I am now entertaining that there is a slight vacuum leak that is causing the N* to run rich and the cats cannot clean/burn off the excessive fuel sufficiently causing the P0420 and P0430 codez, I can run up to 140 with no issues but with the check engine light on I believe not only does it not let you remote start but it reduces the performace level of the engine, they have this device now that well as described to me is like a fogger and it will detect vacuum leaks which is gonna be my next try to solve the check engine issue

Codes P0420,P0430 are cat inefficiency codes that does NOT mean the cats are clogged, which is what you are referring to when you say you can still accelerate to 70 and go 140 and all that. An inefficient cat will/may have less of its element inside and may even be LESS retrictive because it is empty or near empty. Inefficient means it's NOT WORKING.

Now, what you need to go after is what is causing the cats to go bad. Cat failure is usually caused by something else, usually having to do with poor mixture control(rich condition or lean condition), or even a misfire for a long time, whatever that can cause the cats to work so hard they burn thenselves out and thus...loose efficiency. So, replacing cats won't always fix the car.

Exactly! this is telling you the cats cannot CORRECT the other issue:

[QUOTE=Now, what you need to go after is what is causing the cats to go bad. Cat failure is....

Now the CATS have not failed, they have not went bad... correct the mixture issue and then see how your codes look after you run a tank of fuel thru your "failed" $1900.00 cats

Dealer is going to replace the Cat , said the noise coming from the car on is the loose pieces rattling round till they get hot.
Will update in a few days ,Dealer had to order the parts.
Not sure if they will replace one side or both.
Been getting service from the same Dealership for almost 20 years now with good results most of the time.

I did not mean to imply that I think the tune is responsible for the problem, I just didn't want the tune to be an excuse not to honor warranty work.

[jwall09]

So should i be worried at all that the W4M tune will cause service issues or reduce the life of the car? i have a while left on my loan and i love the car so that would be bad..

[WillySTS]

Mine shifts later and harder with the tune, even without the trans tune, so I would say definately...how much so...can't say.

[Jpjr]

Any response from WFM on what might be throwing the code?

I don't think its the tune, but I'm starting to wonder.

IT isn't the tune. It is crazy to say that it is. Fuel ratios are STOCK and are determined Via the O2 sensors. If you all hook up a wideband/ and or 5 gas tester, you will see that my tunes are EXACTLY commanding the 14.7 at non wot. Just as the stock tune does. If you are blaming fuel ratios, that again is just not valid. I don't disable ANY cat protections or anything that would effect cat performance or life. My tunes burn cleaner, more complete, more efficiently, and are WAY WAY WAY WAY more accurate than stock. Just as everyone sees when they go get emmissions tested and are all ALOT lower than they where previously without the tunes..

Vehicles break they are very complex and contain MANY fail points. The more complex, the more the odds are... stock, modded, it just happens.

I'm sorry to say Jesse but your tuned ECM was the cause of my overheating problems. We swapped your tuned ECM out and put the original back in and the problem was solved. Talk to the folks at Lingenfelter, they knew of the issue, it's some setting in one of the tables, I think they said the idle tables ? (don't quote me, they know) that causes the vehicle to overheat in moderate to high temp conditions even with a fully functional cooling system. There is NO doubt it was your tuned ECM, it was swapped back and my problem was gone. If you wish I will ship this ECM back to you so you can consult with them and look at what's there. You cut us a break on the price originally so I'll send it back and not ask for anything in return. However I will not be using any more of your products. This could have seriously screwed my car up, sorry.

[wait4me]

Idle tables? Those are all stock?? Ill call them right now and ask.. As this is the first i have heard of this....
