Re: Banks Tuner Released!
I may be mistaken, but the body controller is separate and handles the speedo & odometer duties. If so, then that controller sends its info the the ECM so maybe the ECM is the slave and changing it doesn't matter.
Banks & Bluespark are called "piggy back" controllers. The hang onto or intercept real-time signals and monitor and/or change them accordingly. There is probably a log of said signals in the ECM but that would not allow the ASC tech to prove anything. These piggy back tuners are not as sophisticated as an ECM tune, but they can be just as effective at producing power; 2x the cost but maybe you don't want/need all the other benefits. No more cutting into the harnesses these days, plug and play.
As for you folks saying man up when you change the tuning as it is dishonest or the MM Act is baloney, I say what are you smoking? The OEM and the dealer are only as honest as they are made to be which is the reason for the MM act. This is business arrangement; they want your hard earned money however they can get it and the dealer is not your friend. How many times have you gone into a dealer and known it was on them and they end up screwing you in some way. You are professional, courteous and honest when bringing them a warranty item and they treat you like an idiot and still screw you. The way service departments continue to treat women is deplorable. $50k for a truck, the air filter cracks after 3k miles and the OEM & dealer says it is on you because it is a wearable part. I'm gonna break it off in them 'cause its only a matter of time before they break it off in me.
