Yep, I'm sure he is... But I'm just adding my .02$... Take it or leave it... Here is a good bit of information you should read and understand about this person...

"Pretty ambitious I'd say. How are they going to handle such a huge trasition? The Bosch support engineers are great. Both of them. And besides Brian Sakata, Hasselgren, and the Porsche Motorsports folks, who else knows the stuff? The engine builders from Gentalozzi's Trans Am program? CRD? If you took every single person in the industry who is knowledgable about Bosch ECUs, you wouldn't have enough to support the Rolex series, much less Cup. Sure, people can learn, but its not the most intuitive software. There will be a leraning curve involved. And they're going to build harnesses too? Have you tried to get a harness built during build season? Again, between PRS, Sakata, MOTEC and EFI, there's usually a 4-6 week wait. I don't think there's enough capacity in the industry. It will be interesting to see how the decision makers manage the conversion of 125+ cars to a new system, building new harnesses, etc."

You can do what you want, but if it was my project, I would be sending my car to Brian... Wait, I am sending my car to Brian...
