On 2003+ the fuse
number 21 must be removed to disable the digital cluster. •
The
fuse box is generally located to the left of the steering column. Possible locations
depending on body builder: under the dash, under lift-up dash, removable lid on
top of or left side of dash.

Plug
in the Programmer to both the OBD2 and PC. To ensure a good connection you can
test it by opening the WinFLASH program, click on “Tools” then choose
“Vehicle Information”. The calibration screen will come up and list
the VIN and Calibration ID’s. The first cal id is what the program will be
“built” on. You need to check that id against what is most currently
available from GM. If you are capable of performing a SPS update using a Tech2
or MasterTech it is a good idea to do that before you “read” and send
us your file. If you aren’t able to upgrade we can still perform the programming,
it just won’t have the latest updates from GM.
•
Once
you have finished the SPS update, start the engine and let it run for a few seconds.
If it runs rough, it needs to relearn the crank position. Shut off and start again,
accelerate rapidly to the floor and release, let it stabilize and shut off. •
Plug
in the programmer to the OBD2 connector and the PC. Run connection test, if ok
go back to “Tools” and choose “Read”. A “Save As”
screen will pop up, we recommend that you save in “Desktop” and use
a file name that is easy to find like “smith’03-8.1L”.
•
Create
an email To: tech@brazelsrv.com. Attach the file you just read and send along
with any special requests such as speedometer correction, fuel octane, electric
cooling fan on/off temps, etc.
•
You
will be sent a file that will be labeled “smith’03-8.1Lupdate1”,
drag file to desktop.
•
Run
the connection test and than choose “Program”, find the file on your
desktop and open. A last minute warning screen will appear. After you’re
satisfied that all the precautions have been followed, press “ok”
•
A
VIN screen will appear you will say “ok” and then the programming will
begin. It normally takes about 5 minutes to do this. When it’s done it will
let you know, turn the key off for 10 seconds and then start engine. As long as
you don’t get an error message, there is no way the program won’t “take”. |
