I bought mine to tune my old pump gas Dusters six pack, which really helped me on that motor
I took it out before selling that car due to thinking something had gone south on it and it, Innovate LM1 with the LC1 add on, took up a lot of floor space between the bucket seats with no console
I'm going to try and use it again on my current street car soon
My message is they are a good tool and can be reused over and over on other cars
