I think the issue was that in the years past the Cobb OTS maps for some platforms included OBD code “blocking” and actual tuning changes that defeated or altered the parameters. We could make our own modifications, but they finally pulled all our consumer-based support. AFAIK there were none on the Ford or Mazda platforms, but Cobb also covered a few Euro vehicles that were seriously cheating, the oem factory included. We (Ford) just got caught up in the fray.
I’m thinking the US EPA will be seriously neutered in the relatively near future when the planet’s climate nazis are crushed by their own ignorance and stupidity.
