I think that you hit the nail on the head, they underestimated how difficult the nut was going to be to crack. Hell, look at the dyno issues they had, the same issues many of us here have had.

I don't have a dog in the fight, yet, but am extremely interested in the development of the kit and I am certain Bell will know our cars as well as anyone else by the end of the build, but we need to give them time to ensure everything is done right. I knew between the difficulty of the Mercedes ECU and our quirky, little cars that this would not be easy, but I know, in the end, that it will be done as best as it possibly can be.
