I don't know guys, but from my experience I will say that 18:1 is very very lean AFR. This must be absolutely smokeless. I think there is no need to go in such extremes.
In reality even much lower AFRs will keep the car smokeless, at low rpms around 2000rpm even 15.5:1 will be smokeless, in higher revs (over 4000rpm) you need to keep it over 17:1...
But of course there are other things to keep in mind. Fuel pressure, SOI, ...
I didn't see the remap file, so I can't say more than that.
