I have also tried the SmartWhatever device that is supposed to trick it and it doesn't work.

I would put the catless on and the rest of your mods. If you want a quick bang for your buck tune right now I would do the BMS and wait to spend your money on an ECU tune.

Don't get caught up worrying about the CEL. I've had the CEL for probably 11 months now and it's no biggie. You will actually get used to seeing it displayed on the dash lol.
