Start getting misfires once the car fully warms up - why?
I have an FC with an E6X. I finally got it to where it runs smoothly at first, but once the car warms up it starts misfiring quite badly, especially once it is fully heat-soaked. What could cause this, and how can I fix it? I've re-routed the wires, and they are nowhere near anything that should cause interference. I have two CAS's , and both have this problem. One seems to be a little worse, but it could just be that it was much hotter outside. I have read of other people have this problem, and also read that magnet clearancing might be a problem. How do you clearance the magnets, and what should the clearances be?
I just bought a RA10 since I'm so fed up with it, but I'm worried that this problem might transfer over. Any suggestions?

you can also try gathering all the CAS wiring ends into a drill chuck and gently twisting them up into a bundle
or replacing that wiring back to the ECU with some shielded co-ax ( shield tied to earth at the ecu end )
as just two methods of combating RFI
myself think though that if the problems get worse as the car warms its air gap,,or earth potential related
PS ,, have you tried fiddling the gain and filter settings yet?,, they may be just off
