Remote starters, how do they work?!?? [split]

It did end quick because I am not interested in fighting on the internet and I realized that I didn’t want to mess with Kenny’s thread. On top of that I have no 100% proof that a car starter will clog your cats. Although, knowing how EMS systems work and how a catalytic converter works and overly rich AFR is VERY likely to damage it. No questions about it.

You also had a high-performance cat which can tolerate a bit more abuse not to mention I’m sure it didn’t have 8+ years and 100k+ miles.

That being said, SAI in my mom’s A4 was probably leaky like they all are, lol. And that did NOT help. Either way, it just proves more to the point that an overly rich startup mixture is bad for cars/cats, hence why Audi/VW/whatever other makes use it add the SAI system to help prevent cat damage.

Side note Mike, I CAN TUNE YOUR JETTA NOW! Delete O2’s SAI, whatever you want. Let me know your ECU part number and I can let you know for sure! I can tune it as long as it’s not chipped already

And that pretty much sums it up. I realized after posting that it could be detrimental to sales so I pulled all of my posts. GLWS’s man!

For the record, Drew came right in fighting rather then explaining anything. Right off the bat calling me a complete idiot and how I was completely wrong. Which is not the case. It’s behind us, leave it at that. And as far as I’m concerned, an over rich AFR will still damage a catalytic converter.
