Bee*R Rev Limiter Toyota MR2 GT SW20 3SGE - ShootAll Ballers Quick Tips - Fixed Bee R not working

While installing a Bee*R into Ben's Toyota MR2 SW20, we hit a problem. The Bee*R Flashed at the right revs but wouldn't limit the engine and so allowing the revs to continue to climb. After watching many install videos and reading up on the problem we eventually found the install guide we had with the Bee*R had a mistake on it.
We would like to point out we didn't by the Bee*R new and so cant confirm if the instructions where the same that came with the unit from the factory or not, but after seeing a lot of people hitting the same problems we decided to put our finds online.
