Re: PCM Problems - Please Help!!

hp tuners,you have to pull a vin from a 97 car to match up so sadly bigbryan is right, i have a 96 camaro with a 97 pcm and it works great, you should really try my friend jeff,he does every thing for $50 bucks so you could have gotten it from him cheaper than pcmforless.

This all refers to programing not reading. Reading is non intrusive.

Reading the VCM

Sorry, here is the correct one and it is for reading the PCM. When your reading the PCM your pulling all the data out to read so if you disrupt it you can damage your PCM. Notice it says do not start or turn on accessories. This info is in the help section on HPtuners, alot of info in there.


To read the VCM follow these steps:
Plug the interface cable into the vehicle OBD2 port and PC serial/USB interface. See Connecting to the Vehicle section for more information.
Open VCM Editor, ensure no files are currently open and select "Read Entire" from the "Flash" menu. Alternatively, click the "Read VCM" icon on the toolbar. The Read VCM form will appear.
Put the key in the ignition and turn to the ON position (do not start the vehicle).
Make sure the doors are closed and accessories are turned off (do not lock or unlock the doors during reading or writing procedures or operate any vehicle accessories)
Wait 10 to 15 seconds.
Click the "Begin" button.
Allow the PC to read the VCM until the status says "VCM Read Completed".
Turn off ignition and optionally unplug the interface cable.
The file is now automatically opened in the VCM Editor and modification can begin. We recommend that if this is the initial read of the stock VCM that you save (and backup) the file with a meaningful name such as "stock.hpt" before any modifications are made. You may wish to restore your vehicle to the stock tune at a later date.
