Attention CS+CTS owners.
DO NOT USE PEGASUS!
You must now use the CD that came with the programmer.
Which Edge calls FUSION.
Thank you for reading this sticky and have a great day!

If you update the firmware in a CS/CTS, the truck (and unit) MUST BE IN THE LEVEL 0, STOCK TUNE STATE! This advice is shown in the manual on page 56 (in small print).

If you do not return your truck to stock before updating the firmware, you will probably wipe out your truck's stock tune! This MAY force you to have your truck reflashed at the dealer's (for a fee).

Also, if you already have custom tunes on a CS/CTS, DO NOT apply a Fusion firmware update! If you do, it will replace your custom tunes with canned tunes!

If things change, I will modify this posting - but for now, consider it a warning!

Sometimes, things can go wrong. If the CS or CTS seems to be malfunctioning or possibly "frozen" up while in use, it may need to be "rebooted". Do it this way:

Turn the ignition key OFF and unplug the unit from the OBD port. Wait a bit, maybe 30 seconds to let any internal "memory charge" bleed off, then reconnect the unit to the OBDII port with the key OFF!

If you see the "splash screen", the unit is starting to reboot normally. Wait until you are instructed to turn the key ON, then follow the instructions to complete the reboot process.

This should restore your CS/CTS to normal operation.

This has been covered before, in other threads for other programmers, but the advice is still correct. If you live in an area where they do emissions testing, on newer vehicles they simply plug a computer into your OBDII port and check for codes. If you show ANY engine or emissions equipment code, you will fail.

Setting your truck back to stock will set the P1000 drive cycle code. This code stays in place for a long time unless you operate the truck through the driving sequence that resets it - which is a VERY complicated process. It will eventually go away through normal driving, but I saw it last for at least 50 miles on my truck after I set it back to stock once. This code would cause an emissions test failure.

Setting the PCM to an advanced tune such as Towing or Performance always clears this code. If nothing else is wrong with the vehicle it should pass an emissions test without trouble. Simply disconnect the OBD cable at the OBDII port and tuck it up behind the dash so the testers have free access to the port. I did not even remove my CTS from the dash.

You can also use the CS/CTS to check for any codes BEFORE you take your truck in for testing, which I did. Use the [Diagnostics]->[Trouble Codes]->[Read DTCs] menu item. You can also "clear" codes (except for the P1000 code) using the [Clear DTCs] choice, but if there's a mechanical problem, the code will return. When you see a code, it's telling you to fix something.

Edit: My inspection report has a box labeled "Malfunction Indicator Light Status" and the entry "Commanded OFF", which has a "Pass/Fail" value and mine was "Pass".

I'm guessing here, but I suspect they are checking for someone possibly "disabling" the "Wrench Light" or other P-Code status indicator. I don't know that using the "Clear Codes" option would cause a truck to fail this test, but it might. I think it's not a good idea to "Clear Codes" just before an emissions test.
