deprogramming f45 after conversion to zo6 shocks
Is anyone familiar with a chevrolet garage who is expert in deprogramming my selective ride module now that I have installed new zo6 shocks. i told my local dealer they needed to do that but of course they were knowledgaeble than me. now I have 3 warning messages showing. Any info would be appreciated

If U R mechanically inclined Y not do the Radio Shack 10 ohm resistor install on the old F45 wiring.
I did this over 3 yrs. ago on my F45 removal & still OK with no probs.

About the the F45 - to - F55 upgrade...I emailed an engineer at GM and the following is what he emailed back:
Thanks for your kind words, and interest in our Magnetic Ride technology.
The short answer to your question is 'no.' There is a bit of a
relationship between the previous F45 real time damping system and the new
F55 Magnetic Ride Control system. They use quite similar computing and
electronics to analyze the road surface, yaw rate, steering wheel angle,
wheel position, etc to determine the appropriate damping rates.
However, the new system has much, much more capability. And, to your
question, it is not really compatible with the previous F45 system. The
new F55 system uses the world's first "valveless" shock dampers, using
magnetorheological technology (hence the "magnetic ride" name). F45 (like
almost all similar shock dampers on all cars) used articulating valves to
operate the shock damper. The magnetic ride system uses
magnetically-charged fluid instead of valves to actuate the shocks. The
computer system takes in all the data listed above to determine the correct
damping rate at all 4 wheels independently and continuously -- much like
what F45 did. Here's the difference: The system sends an electric current
to each damper. The fluid in the dampers contain tiny iron particles that
react magnetically to that electric current and that's what governs the
shock damping. This happens within just a few milliseconds -- about 5
times faster than F45, which relied on normal mechancial valves that are
much slower than magnetic energy. Without the Magnetic Ride shock dampers,
which are only on Corvette (with the F55 option), Cadillac STS and Cadillac
XLR there is no way you could mimic this system. This technology is a
"first" developed by GM and Delphi. Even if you could obtain the shocks
someday, there are extremely specific electronic calibrations and tuning
that make the entire system work properly. I have heard that some
aftermarket companies are trying to develop something like this. And
perhaps those would work to some extent, I don't know. I do know that the
algorithms and requirements dialed into our system are extremely complex
and well-researched for the exact driving dynamics our engineers desire --
we have engeineers who've literally been developing this stuff for 20
years, not the kind of thing that can be easily duplicated or adapted,
frankly.
The F45 was a "first generation" attempt at this kind of technology. But
in the 1990s, the magnetorheological dampers were not yet perfected. So,
it was the best we could do at the time, and it results in a very pleasing
ride system. The new MR system takes advantage of the electronic controls
pioneered by that system -- but now we have shock dampers that are greatly
more sophisticated. The result is smooth, well controlled ride motions
that we can tailor to a much more precise degree. F45 was good, but the
new system is the full realization of the technology.

Yes any chevy dealer can do it. You need a Tech II device. make sure you unplug the F45 control boxes in the rear trunk before deleting the option otherwise it will not delete.

Ya I guess im not really sure... I have a 2001. I do know that I have three ride choices. Touring, sport, and performance ( I think that is what the console reads)

That is the F45 ride control option.
I suggest you get yourself a set of C6zo6 shocks ( GMPARTSHOUSE.COM has the best price as I recall) and some resistors from Radio Shack and restore the handeling and ride on the car.
They also sell the same thing prepackeged with connectors so there is no soldering if you want to spend the extra $$$ They are called SIMULATORS (not inexpensive) Google C5 F45 Simulators and you will find many places selling them. I personally would do the resistors, they are much less expensive.
