A racer I know used to pick fuel by Fiat.

Anything that wouldn't ping in his Fiat was good enough for his race car. At a lot of places 91 would still ping, at some places 87 was good enough.

That was a long time ago before race gas was a common thing but it shows how far off the octane numbers can be.

If you ever de-cat your car, you might figure out a way to get low lead 100 from your local municipal airport.

This is the reason why I don't own an Accessport yet, the lack of tuning software means I would have to rely on someone else's idea of what kind of fuel, parts and a safe tune I should have.

Release tuning software and I'll order one that same day.

There are only a hand full of ODMs designing EFI computers or PCMs (power train control module).

With the amount of re-use business want to do, I'm not surprised that error messages are the same between different manufacturers.

As far as what's in a Cobb tune, its probably almost entirely different table values and enabling additional functionality built in to the PCM. Neither of those would change error codes.

It certainly can lead to errors being generated but that's a different story.
