What sensors does the microtech need to run? Do you need to get sensors with the ecu or buy them seperately (any idea how much)? I was looking at getting an mtx-12 but the seller was saying it was just the unit and loom so I was kind of concerned about how much the rest might be to get together. Also with the preprogrammed chip they put in them (for the plug in and play start to tuning) how difficult is this to change? - this unit was originally set-up for a rotary and I need to set it up for a 4cyl, does it must mean having to start from scratch or are there more fundamental problems? Thanks for you help, Chris.
