Thanks for the reply! I opened the APC control box, and found 3 potentiometers. They are marked "P", "K" and "F". Iguess P is for preassure and perhaps K stands for the sensitivity of the knock sensor. I have ni idea what the F stands for. I have access to a nice chip for the LH2.2, but my car has Lambda sensor and Direct Ignition, so there is not possible to swap chip. The advantage of this chip is, apart for higher max RPM, that it gives more fuel when "racing" so the pistons wont overheat. It seems that almost every part is different between cars with and without catalytic converter. Including the turbo compressor. /dot
