You *should* have the ROW tune anyway which does away with our secondary 02's and air pump related junk.

The system can be fooled, but the expense is not worth it. Just run it with the CEL

I think this is what I will have to do, as I want to remove as much "extra" stuff as possible.

What is the ROW tune?

ROW= rest of world tune, no secondary 02's and no smog/air pump

In the USA we receive the LEV tune = Low emissions vehicle which includes the smog pump and secondary 02's and maybe a few other monitoring type sensors

In our race cars, we push the stock ROW tune to them, then manipulate that tune to make more power. This cleans everything up under the car and cleans up the engine compartment (less crap)

I'd have to look through the country list to see which tune your car received!

We remove everything...

DO NOT cap off the vent line from the tank

ask me how I know

Just trim it back and leave it behind the inner fenderwell liner.

Not sure if this applies, but is there any concern about the Boxster Spec rules regarding "no modification to the ECU"? I suppose it depends on your race class and sanctioning body.

I was on the original rules committee in 2005 that wrote the BoxsterSpec rules

I do this to my SCCA AutoX cars and SCCA Road race cars, or the GT class NASA cars

I'm the one who can "plugin" and see if you changed anything from the stock tune

On the spec cars *most* of us just safety wire the secondary 02's up and out of the way. It keeps the CEL from coming on for that function.

I believe EricO had removed his from the system when they paid to have the immobilizer removed. As someone pointed out in another post, it is possible to have all the excess removed.. but at 1k a pop? is it worth it? Just buy a generic code reader and check your codes before loading the car for the track!
