PH1 T4 has Siemens EMS2000 ECU. As far as I know, it is quite difficult to tune. I have been told that EPROM cannot be programed in the ECU, but should be taken out (de-soldered?) and programed separately in EPROM programator. I know it can be done, but obviously people who know how to do it are not willing to share :-(
