Do the 82mm tb error codes cause the car to run differently?
Just gathering information and was curious if the error code the 82mms can throw puts the car in any type of limp mode or does it just annoy you with constant cel?
I know these tb's can be put into emergency maps in the ecu with certain failures.
Thanks for any info.

My DIY kit hasn't thrown a code either. Idles great, gobs of snap, and so far has 450 miles on it with no issues. I used a MB throttle body too. Not sure if ones with CEL's are due to alternative Bosch units or not.

Hey Jim, from what I understand is that if you use a MB 82MM you should not throw any codes. I know that the 997 GT3 uses a 82MM and they are somewhere around $350-$400 but I believe that those may throw codes and Audi has a 82MM as well but I think it to will throw a cel.

I have the Porsche/Audi/VW 82mm unit on my car and no code. When I first installed it I did have an ESP message (white lettering) and the car drove perfect. Later on I found out it's just a loose connection in one of the six wires that plug into the TB. Pushed the wires back in, a little electrical tape, problem fixed.

Does Bruce sell the RENNtech one? I know of at least 4 cars using the RENNtech version of the 82mm TB (MB) and none of them had codes or any problems what so ever with drivability or anything else.

The codes associated with the TB installs happen because of multiple issues. First, if you use an adapter plate that bolts to the enlarged inlet like so many kits available, there are 2 potential places for air leaks, second, using anything other than an MB throttle body can have throttle position sensors wired differently, third, you have to raise base idle, either with an SDS in control unit adaptations, or via a tune to help the ECU handle the extra air at idle. Without doing that, the MAP sensors see the extra air, but the ME doesn't know what to do with it. Lastly, if you take the whole car apart to do the install and misconnect something(vaccuum lines or electrical) or don't connect the crankcase breather hoses to the TB, then you will have even more problems. Just my $.02

Must have been the error code many were talking about.

Thanks for chiming in Bruce. So what were the codes 505 and 507. Was it that idle thing? I know it wasn't your setup but I was curious.

I will have (5) 55K airboxes available the second week of October and yes they do fit 82mm tb's.
