So you used my advise huh? Lol anyways are you sure the ECU is stock? Alot of people when they chip a car use the CEL as a shift light and in the VX I believe it has an arrow going up for a shift light. I really don't know what it is but if it went off it mighta just been from you getting on it somewhere something came disconnected a little bit. I really don't know. Anyways rep me!!!
