The Lexia tesing guy @ the Citroen garage told me a trick on how to get the ECU to learn the changes (sensors and other) after you made them and reconected the batery.
1. Reconect the batery after 30min.
2. Put the key in the ignition and turn it in position two so the ECU and the other lights come on. Wait 10 sec. and switch it off. (if the Saxo is pre 98 and has a keypad code put in code within the 10 sec.)
3. Turn the key again in position two and start the car in 3 seconds.
This way the ECU has registered the changes and the FUEL PUMP will not run at full pressure FOREVER after you've disconected the battery.
I have tried this and it works for me. The car was smoother immediatly after I put the new MAP. The pump spun down after the normal 3 seconds.
I have no idea if this replaces the Lexia reset and fault code erasing but its one more things you know about your SAXO.
