Diagnostic Invisibility

[vishnut_vadmin]

The Procede is first CANbus integrated tuning system on the market. As such, it offers many distinct advantages over all other tuning options. One of them being the ability to be diagnostically invisible. Here's what you need to know (and do) in order to keep your dealership from knowing that you have been running with the Procede:

1) Leave the CANclear feature active when driving your car. The default setting is ON so just leave it alone. Next, unplug your exhaust bypass valve solenoid. It is located in your trunk. This is a very popular "modification" to make your exhaust note sound better. But, more importantly, the Procede's clever CANclear function will use the benign shadow code this modification generates to displace any potentially warranty-voiding tuning codes that would otherwise be stored in the DME (even after a code clear).

2) Before dropping your car off at the dealership for work/service, plug the exhaust valve solenoid back in and clear all codes with the Procede. Truthfully, isn't even necessary since the CANclear will do this periodically by itself. But it's worth doing anyway just to play it safe. And it only takes 5 seconds of your time.

3) Once the codes are cleared, physically remove the Procede. Dealership techs are instructed to inspect/look for tunes in some circumstances. So removing it is important. If, for some reason, you simply cannot remove it (and are willing to gamble with your warranty), you can leave it installed. But you MUST do the following:
-Toggle to Valet Mode (using the DTC mapswitching feature)
-Turn CANclear OFF (in the User Adjustable menu)
Not doing BOTH of these will make it impossible for the dealership's diagnostic tools to communicate with your DME.

When you get your car back, all you need to do is:

1) Install your Procede
2) Unplug the exhaust valve solenoid

And get back to driving!
