Disable the F45 option using Tech2
97 Vette
Connected Tech2 and the menu items are:
0 Diagnostic
1 Service Program System
2 View Captured Data
3 Tool Options
4 Getting Started
Under the Service Program System there is one item available for reprogramming - the PCM. I did quick google and read that after 300 off/on ignition cycles the BCM is locked and no longer programmable. Must be why it is not in the list. Appears a new BCM would be needed to go that route. Did not see any reman unit or unlocking service available.
I have already removed the shocks from car. In addition I removed the position sensors and am getting error codes. I know about the resistor mod for the shocks but have not seen anything for the position sensor.
Any suggestions?

Also, try a search on F45 Removal, as there is a certain order to follow in disconnecting components and flashing the BCM.

You have to go into diagnostics. Here are directions. Although they are biased towards turning on TPSs on a Z06, they do show where the F45 option is located.

Got F45 disabled. Tip of the hat to fdxpilot & Wicked C5 for link to: http://www.stopforce.com/RPO.html which has the procedure.
Error in 1st post was selecting option #1 - Service Program System, which is used to program NEW modules.
IIR from working on computers, hot plugging serial devices was a no-no. So I unplugged all the connectors on the ECS unit before starting.
1. Disconnect the Electronic Suspension Control (ESC), PULL both connectors!
Now summarizing the procedure from the stopforce link:
2. Navigating the Tech2
From [Main Menu]
select F0: Diagnostics
From [Vehicle Identification]
select year
select type
From [System Selection Menu]
select F1: Body
From [Vehicle Identification]
select product line (Y)
select body style
select trans
From [Body]
select F0: Body Control Module
From [Body Control Module]
select F2: Special Functions
From [Special Functions]
select F1:BCM RPO Reprogram
From [Setup New BCM]
select US & Canada RPO V73
From [BCM RPO Reprogram]
hilight RPO F45 option line
press deselect
Select Save Changes
4. Turn off the car.
5. Turn the car on and verify that the dreaded - MAX SPEED 80 MPH - is gone.

I tried removing the F45 today on a '97 with the TECH II but failed. It would not disable. Could not get past the "Setup new BCM" page with the delete option and then save for the F45. It did nothing when "delete option" was selected. Starting thinking I needed to disconnect the Electronic Suspension Control (ESC) first. Will it not disable with the ESC connected?
Also, anyone in the Delaware County, Pa. area willing to share their Tech II. Think I wore out my welcome at the Dealer.

As long as the BCM sees a Suspension computer, it will not allow the F45 option to be deleted.
Also, any GM dealer will have a Tech II.

Well round 2 was another failure on the '97. We disconnected both plugs first from the Electronic Suspension Control (ESC), then turned on the ignition, and still cannot delete the F45 option. The option shows but nothing happens at all when the remove option key is pressed. Any help is appreciated.

Yep, pretty sure we followed it to a tee. There was some differences later on in the screens, like it asked if a special handling package was installed at one point. There wasn't a whole lot of options to chose from so I can't see where we could have taken a wrong turn but it did not exactly match the instructions. Also. the last screen showed the available options and did have a deselect option, but no asterisks. I'm wondering if this is a '97 model year issue?

FYI, the stopforce site has been up and down the last few years. the instructions are mirrored at http://techvelocity.com/stopforce/RPO.html in case the stopforce site is down.

There is a little more to turning off the F45 than shown in that link. It shows how to get to the correct menu but not the things you have to do in order to make the delete permanent. Here are the steps:
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 turns on automatically]
7. Turn car on to verify the "max speed 80 mph" is gone.
8. Unplug Tech 2.
