Secondary air injection code is 0235
Rear 02 code is 0239
Speed limit deactivation code is 0281

So what your saying is that if I go to code 0281, I can take out my top speed limiter on the car?

Sure, engine was running. But there is no digital codes like 0235, 0239 at all. Only text menus like "Vmax", "ASR" etc.

Frankly, you get what you pay for, even from the China clones. They are cheap, in more ways than one. I've read some real horror stories about 'em. And they'll loaded with viruses. The viruses don't affect the car, but if you want to transfer data via a thumb drive...

If you want a DAS unit, that is complete and works out if the box, contact Shardul (first post). And he's in the US.

Cheers,
Jeff
