I use to have that on my old euro racer, it was a 95 nissan maxima. Not the best thing caused a lot of problems. This car i had a lot of mods done to it pretty fast four door car. I use to have my check engine light go on quite a bit while running tgis computer, and would take the car to my mechanic that tuned the car for me and he would say all the computer info would get erased. The car forgot how much air to fuel when to, shoot a spark what temp to run at and various oth er problems. I would not recommend it, it had it a while ago so maybe the company has made changes a fixed bugs since it came out but i had bad experiences.
