Once the FIA started demanding access to ECU's, programmers learned their system and figured out ways to produce faked checksums before the race, so that they matched with the post-race checksum. That is, after the traction control and ABS programs self-deleted on the parade lap post-race. This was common knowledge in the paddock, but no one could prove anything. Even then, everyone was doing it so the field eventually became level. Cheating and "pushing the rules" has a very long and storied past in F1. If you're not caught cheating every few years, most would assume you're not trying hard enough to win. Edit: Here's a link to a Reddit thread about McLaren's fiddle break. It was a dual braking setup that allowed the driver to only apply the rear brakes. Photographers noticed that sometimes only the rear brakes glowed red instead of all brakes glowing red. Many accused them of using traction control and ABS. In reality, it was just an independent braking circuit (which was illegal). https://www.reddit.com/r/formula1/comments/1ux791/an_old_f1_shot_of_mclarens_fiddle_brake_a_second/ https://www.reddit.com/r/formula1/comments/1ux791/an_old_f1_...
