ITBs likely pushed them away from stock engine management. I'm guessing he also wanted a cable throttle, and I'm going to assume that the duratec uses DBW.

If they're running aftermarket engine management, any decent one will have VVT capability. Regardless of whether a cable throttle or DBW is used.

For what it's worth, it's totally possible and easy to run ITBs (cable or DBW) with factory engine management. It's already been done in the NC MX-5 community.

Interesting. No one has figured out how to run cable throttles on DBW BMWs, in spite of a very well hacked factory DME.

I kind of question why anyone would want to do it. There are so many advantages to DBW and no real downside.
