Even on the D-Jetronic ECUs which were adjustable, that was only an idle adjustment. I don't know if it had any effect off idle. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org
