Sounds like a great tool but I don't think that they have one available for the '04s yet.johnt said:Depending on your near term plans, there may be one more option for you. If you're thinking about possibly getting a PCM tuner in the future, The HP Tuners programmer comes with its own scan tool for free. It can display up to 24 parameters and the sampling rate is 0.1 seconds. I've been using it recently and I think the extra sample points are great. Way better than my old tool.
