Hello has a clue, have me a C20NE processed channels on 40mm valve seats to outside. Compression raised to 10.5 SEH camshaft, adjustable cam wheel, fan manifold, 24V Kat with 57mm passage group N system. Eprom adapted. now to the problem; I let the cam run a little ahead( wanted to lose power and responsiveness from below) engine runs well, now also turns willingly up to 6800/Umin, at my age I turn but not there, have at 6500 good connection. w I start with high outdoor counters in the city traffic uphill e.g. ringing for a fraction of a second. so my thinking; the engine has an OT dealer. the rest of the ignition characteristic is stored in the Eprom, distributor is rigid. because I run the camshaft earlier. so in the direction of a clock. away from the make-up. is the runner in the cap yes also earlier. if I put the cam in the direction of the original the runner is later on the first Zylind he and the spark. or am I completely on the wooden way.??? if someone can think in and give me advice please answer. I thank you in advance. gr. poorin Possmann
