Im looking at getting a tuning device inexpensivly. I was looking at tweecer and the eec tuner. is there a big advantage of one over the other. I searched around a bit and alot of people say the eec tuner is "old school" now but why? U can get eec tuner with data logging for like 400 and tweecer rt is 560. I mean i guess i could always just go without datalogging. I dunno I dont know enough about these things.
