You will need the right iteration sensor. It will be the for the 987.1 IIRC. I am sure others here will follow up more details that I have omitted

Thanks to all of you who've responded. this is helpful.

I've tried, unsuccessfully, to find a dealer who would flash the anniversary edition tune to my car, knowing that this would accommodate the larger MAF holder. The tune that I got from Vivid (VRTuning) ignores the o2 sensors, so it doesn't work to get me past the IM station.

I may determine that, as much as it's a PITA, it may be most simple to swap back in the 986 maf holder for IM testing, and then swap it back out.

(spare me the "save-the-earth" lectures.... look up what "lean condition" means) :cheers:

Seems you are always trying to insulate yourself pre-need from jerks yet you have no issue doing the same to anyone else.

I reprogramed my DME with my PST-2

you can't increase the diameter of the maf housing without adjusting fueling tables. MAF calculates the volume of air ingested using the velocity of the air past the sensor, which of course is a function of the size of the tube it's flowing through. The codes you are getting are generated in regular driving where the O2 sensors read lean/rich. At wide open throttle where the ECU is running on set tables (and not off of O2 sensor feedback), you will be running lean (increased airflow not accounted for because of incorrect maf housing size). Lean is mean, until it's not. Without monitoring this with a wideband O2 and updating to a custom tune you are asking for trouble, especially on track. What is you crazy ;)

You're such a douchebag.

I've been hands off with you because you're so easily triggered, but when you volunteered into my thread, I thought "huh.... ok! Maybe he's finally letting it go!" So I simply responded to you as if you'd never been the dick-head you've been.

But it seems you just can't help yourself, can ya? Most people are a dick sometimes, some people are a dick most of the time. But you? It seems you're one of the rare breed who's a dick all the time.

I'm not going to descend to a place where i'd engage the actual content of your comment, because I refuse to legitimize it.

I'd appreciate it if we could go back to just ignoring each other?

Robert,



Perhaps slightly better performance and the proper match for the 987 MAF diameter; folks here are actively using it. Full disclosure: I have just changed from a third party tune to the stock 986S and planned to go to the 996 ROW. I am not sure about the anniversary tune and don't know anyone using it. I believe the anniversary is geared to the 68mm TB where as the 996 is geared to the 74mm.



You will: be able to start the car without depressing the clutch, reducing engine wear;

not have to worry about post cat o2 sensors/codes; loose the ability to monitor one cam shaft for deviation from ideal.

I run it with a softronic tune. Runs a touch rich, but no issues or codes.

I'm running the same configuration. Same success no codes slightly rich.
