sorrentoaddict 1 Posted April 24, 2006 BX16v CAT. for German and Swiss market = 0 261 200 158 BX 16v non-cat (160 HP) = 0 261 200 354 generally the BX-derived ECUs have slightly more "aggressive" ignition curve, to compensate for the H.P.-pump losses. That is also why the valves usually last much more longer on 405-derived MI-engines, compared to BX-derived ones... Share this post Link to post Share on other sites
