Why ISN'T my check engine light coming on?
So I thought this was somewhat odd - I installed a racing beat dual resignator mid-pipe (yes, I'm 100% it doesn't have a cat) and hooked it up as per all instructions with the stock muffler. It's been about 5 days now that I've been driving the car and I haven't recieved any CEL warnings...
As ironic as this seems, is this something to be worried about? The only thing I could think of is that the previous owner may have had cobb or something similar installed to mask the CEL, but its highly unlikely (given his age and mileage on the vehicle)
I shoudl also point out that when taking the cat off the car and looking into it, I found that there was a rather large hole in the first section of the catalyzers... ie. it looked like it was on its way out eventually. (car has around 35,000 km)
I'm sure its nothing to be worried about... but I found it very strange!

I didn't get a CEL with a borrowed BHR prototype for 3 weeks, 2005.
I was chatting with another member yesterday, who is working on cracking the ECU on his own time just for kicks (yes, he knows there are other options), and he says he thinks that for 04s and 05s (at least) there is a logical error in the code where, under certain situations/environments, the sensors are working fine but the code was written incorrectly and it won't throw a CEL, even though it should.
He likens the coding error to the Toyota coding issues, although obviously with a much less critical component.

Ja, an old fart would never have an Acess Port. Especially MM, he's so damn old............

You mean the stuck throttle issue?

I mean, wouldn't you take advantage of it if you could?
Have to understand it first before that can happen though.
Even so, I still love knowing the "why", and the more something is called odd, the more 'why' I want to know about it
