And I say that because when I first plugged my SCT tuner (an SF3) into my vehicle, it didn't recognize the ECU. Turned out the strategy code wasn't in SCTs tune. They sent me a mini update to resolve it. And the update was minor in that the revised strategy code was the same, except with an added revision letter at the end (i.e., FPBF2a
-- or something close to that, I forget off the top of my head.)
But in the meantime, I was not allowed entry into the ECU to do anything.
How long ago did this happen?
Maybe SCT has since modified their tuners to better
recgonize unsupported strategies, and consequently not let the tuner go forth with its intended processes.
Dunno though, pure conjecture on my part.
