Yes that is correct.

The next step would be to edit the fuel maps of a USA LH2.2 to be those of the Euro LH, which would be possible with the SharkTuner. Then you would have a "federalised" Euro S.

Thanks John,
I still haven't decided if I'm going to use a closed loop, or not. I think I'll post on the the SharkTuner thread to read what others are doing and why. Because I still don't neccessarily get the difference.

Other than a fixed map won't account for engine degredation. That is what I have going on now.

The choice in the end may be dependant on what emmission tests you have to meet ?

OK, then you might just as well stay open loop. The Euro exhaust does not have provision for an O2 sensor...

John,
I've already converted to WBO2 and have a PLX with a wide and narrow band output.
