I second the save thing. My understanding also is that when you make changes you should rewrite all to the ECM, or there is a high possibility that it won't save correctly to the ECM. That is how the VATS didn't get saved the first time by the first tuner. Somehow he didn't rewrite all after he changed the VATS and saved it.
