I have upgraded to a higher flow air filter and my gas milage went to crap...like 22 down to 17mpg. What fuse should I pull to dump the engine control computers memory so it will remap with the new air filter. I had the same problem on my truck and I just unhooked the battery for about 30 minutes. I would do the same except this is the wifes care and she would really not like to reset all the custom setting. Thanks!

Well, apparently there R two different fuse boxes on the GS because on my 400, I remove the yellow 20 amp fuse marked "ECU B" in the box right by the passenger's side strut tower. However, some of the other Members say they don't have that fuse in their rydes so if U're one of them, just look for a fuse which controls the engine ECU. BTW - U may lose the memory on the driver's seat so make sure that it's in the WIFE'S position before disconnecting the fuse. That way it's a simple matter of pressing the seat memory button for her as it's already in HER position - helps keep the peace ( I speak from experience!!! ).
