I've found the anti foulers to work.

 

 

Well, some people like to analyze things, while others prefer to be blissfully ignorant. I, for one, and obviously others here as well, find it quite interesting. The engineers like to try to make it difficult to defeat their systems, and it's a battle of wits when 2 minutes after release, savvy people start trying to reverse engineer those systems and invent work arounds. I remember when OBD2 was first about to be released. Many said "Hot Rodding is dead!!" "With OBD2 you won't even be able to change TIRE SIZE without getting into trouble!!"

Luckily, hot rodding survived and even the scary OBD2 was soon analyzed and tamed and by the same type of people whom participate here...

Yea until you get to Cali and they can tell when you've flashed that OBDII Computer and you fail an inspection, so people were kind of right there.

There is a such thing as over-analyzing. Some of us bolt up our mods, hook the laptop up to the car, adjust the tune to dial it in and let er rip.

This case here if it was me I'd call WS6Store or anyone else that sells them Sims and see if they'd just ship a single one. I've talked to quite a few companies over the years with similar cases and that's happened.

 

Personally, I have no problem answering questions and I do understand that some folks have good reasons for wanting or needing to know exactly how something works before committing to a course of action. There are some situations or goals or requirements that need special attention and understanding to determine the best solution. But in this case, we are now just analyzing for the sake of analyzing. The solution (actually more than one) has been presented, the product is still in production, and it works as intended for this application without any operational downsides. Further scrutiny of the item will lead to nothing more than the rabbit hole of analysis paralysis.

Regarding OBDII, it's literally antique now. Meaning, the earliest examples can be exempted from emissions testing in many states. I re-registered my '98 as an antique vehicle in 2023 when it hit 25 years old. At this point, emissions compliance with this car is as meaningless to me as it is for my other "antiques". In a few more years even the newest 4th gen F-bodies will be eligible for AV status, thus exemptable in many states. And that's not even accounting for the fact that some states don't have testing (or only test in certain areas) in the first place, and some of us have had other exemption options available even before we had custom tuning (or in cases where custom tuning wouldn't suffice).

Having said all of that, you are still just one O2 simulator away from solving the initial problem which prompted this thread. The rest, for better or worse, has just been discourse.
