2004 F55 Delete - Can it be done??
2004 F55 Delete
Can this be done on the 2004?
Ive been searching, some say yes, some say no.
Who has done this successfully on a 2004 commemorative edition?? Sounds like 2004 is a odd duck.
Im looking at a 2004 this weekend with 65k miles on it. Im wondering if I can delete the F55 when the shocks fail.

Hello,
I have a 2004 Commemorative edition that came with F55, it can be deleted with a Tech II. I just did it two months ago with the help of someone on this forum.
The correct procedure is:
1. Use the Tech II to delete the F45 option.
2. Remove the large gray connector. Then turn key off but keep Tech II plugged in.
3. Go back to F55 module and remove the last two connectors.
4. Disconnect everything and unplug the battery for a few hours. Mine was still giving me the error messages until I completed this step.
No warning lights and no speed limiter.

Here ya go
1. Hook up Tech 2, turn car on, make sure module in the rear is plugged in. Do not unplug the rear module.
2. Use Tech 2 to delete the F45 option (F55 does not appear on the menu screen, use F45).
3. Save new configuration.
4. Do not turn car off, do not remove Tech 2. Go to the module in the rear of the car, unplug the grey connector (the widest one), leave any other plug(s) in. [leave the other 1 (F45) or 2 (F55) plugged in]
5. Turn off car, leave Tech 2 plugged in.
6. Remove remaining plugs from module in the rear of car. [never plug them back in again, if you do the F45/F55 turns on automatically]
7. Turn car on to verify the "max speed 80 mph" is gone.
8. Unplug Tech 2.

The F55 is MUCH better than the F45 system. The only reason I would replace it if its working and you like the ride would be to change the shocks to a more performance oriented standard shock. The F-45 and F55 set up comes with a base FE-1 suspension. Smaller sway bars and lighter springs.
If you wanted to achieve a more performance oriented car, you could do it in steps. Change the shocks to GM OEM C6 ZO6 Shocks, then step up to Z-51 or ZO6 springs and sway bars.
My ZO6 one day gave me a scare when I entered a high speed highway sweeping turn at a very good rate of speed and the car started to skidder sideways as the wheels became unsettled over the rough pavement. It was all due to worn OEM shocks that could not control the wheels on the rough surface in a curve. New C6 ZO6 shocks cured that 100%.
The answer to your question is YES, you can delete the F-55 RPO Option from your BCM successfully utilizing the GM Tech2. You just have to get a TECH-2 and follow the steps to delete it. NEVER EVER plug the module connectors back in to the module as it will automatically restore the F-55 RPO to the BCM! NO Tech2 needed! LOL!
