Yes, they have the optical pickup. They said that they put a piece of reflective tape on the crank pulley to use for a signal. I am planning on taking my truck there in the next week or so, that way they can take a look and get an idea of what they need to do. I know they have done powerstrokes there before because they gave me a graph from one to look at, so they have probably done a few cummins also.
The only question I have is with the auto's. Is there anything special needed to dyno a truck with an auto?
I should be able to schedule a date by the end of the week, It looks like we will have no problem getting enough trucks.
If you guys have any more questions, let me know.
Thanks,
Matt
