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.

I know that there is at least one 82mm TB kit that doesn't throw codes.....Contact Bruce at TTM

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.

+1 been driving around with the porsche 82mm TB and no codes for the past 5 months!

Wonder why people threw codes in the first place?

Just not wired up correctly (the wires not in correct position on the connector)

+1, best 82mm on the market. I have it on my car and have NEVER gotten a code. Car runs fantastically with it.

did you have to rewire or move the pins in order for it to work or was it plug n play? and does anyone know why the 997 GT3 82mm is cheaper than the MB one?

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

Perfect, just what I was looking for. Thanks Nick!!

Must have been the error code many were talking about.

The 997 GT3 throttle body's blade opens the opposite way so you must swap 1 with 4 and 5 with 6 in the extension harness for this to work. I used the GT3 throttle body in my previous kit but using OEM MB parts makes all of the difference IMO. More costly...yes, 100% problem free...ABSOLUTELY and it looks stock!

TTMotorsports

Sounds like you have experience with that garbage bolt on adapter plate 82mm set up! Couldn't get it to work huh? Let me guess..505 and 507 codes?

TTMotorsports

Thanks Marcus!

Jakpro1

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.

TTMotorsports

The codes are associated with the Idle Control System. The range that the tb blade is set, from the factory to open, falls out of these set parameters since opening at the same percentage of a stock tb you are getting a greater volume of air with the 82. You correct that issue by increasing the idle ~60 rpms and that issue is corrected. You are now back in the correct percentage range for the throttle blade position

Hope that makes sense!

Jakpro1

Perfect! Thanks Bruce!

Will be ordering those python tubes from you soon!

TTMotorsports

Python tubes are not scheduled in yet for another production run yet. Trying to get a commitment from the manufacturing company.

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

I get codes left and right- increased idle **** sucks!!
If i wasn't able to read them and erase them myself i would have gone nuts a long time ago..

how much is the ttm TB kit

Bruce-Just sent you an email about your kit

do the MB units require an adaptor flange? or is there a s/c inlet made for a 82mm.
