I bought a ECU for when my truck decided to idle erratically and stall. It wasn't that so I don't need it. I bought it for $75 so I want $200. Kidding just give me 75 plus shipping. I drove a few hundred miles on it and it worked flawlessly. I have been told it does not have a speed limiter. No clue what that means. I hit 85 on the 405 the other day with it in and thought I would die as my ears wanted to explode from the sound of the soft top.
