Any thoughts on whether or not a second set of high impedance injectors
specially balanced at the low end (for use at smog time)could make
enough of a differance in HC ?
Just trying to avoid having to buy the newer Link.

Glad I kept those. So just swap and retune for NA rows. Start off using
Link maps for normally aspirated instead of Turbo with 550cc injectors?
Thanks

That's pretty much what the NA map is for. I just don't like having to say
"wait a minute while I swap injectors" to the guys running the roadside
inspection stations.

How do the roadside inspection stations work? They set up roadblocks
to stop traffic at random points and make you wait half an hour while
they do a smog test? Or what?

Make sure you only import the fuel map and inj offset for the na
injectors. DON'T use the na full map!=20

Basically, yes. You wait for your turn, then you wait while they run it.

Thank GOD they haven't hit me yet.

No, we had quite the discussion on the SDMC board. They pull you over. If
you don't stop you (presumably?) get in big trouble. Then you line up. I
can't remember if you can decline the test then you're required to go to a
ref station, or if you just plain can't decline it at all.

There's no penalty for not passing, except that if you don't, you have to go
to a ref station. And if they see anything they don't like, you have to go
to a ref station.

The initial idea was good - get a representative measure of the cars on the
road (nowhere NEAR as good as the automated onramp ones mentioned earlier,
in my opininon). But then they decided hey let's have a field day with it.
Well, so far they haven't gotten me. Seems a lot of trouble to haul mobile
dynos everywhere, but they do. I sure wish I had an EO.

Good thing that they have no legal right to force you to submit to the
silly roadside test. (at least that was the way it used to be.)
