Man would I love to see a datalog of the commanded ADV from that system. Do you
recall seeing much of a difference between the 4 pairs of jugs?

BTW, are those the new LSU4 sensors, or old LSM-11s you're using now? and can
you say whose instrumentation you're using with them Boschs?

Finally, what does the Vette team have in the way of surprises planned for us
spectators this year?? Anything else newNstriking on the 7L specifically?

Pardon the 20 questions, & TIA for anything divulgeable :),
