Hydra

Anybody got a hydra in an excursion? Do you have a flashing theft light? I spoke with php over email and they said there is no way of getting it to stop. But you can drive it that way! What am I supposed to do put some duct tape on my dash?

Above the accelerator pedal there is a small module with a four-wire connector (green or red in color). Unplug that and your light won't flash.

However, there should be an option in the Hydraflash software that allows you to enable PATSin the calibration.

If hydra can accept tunes from different vendors, could I get a tune from someone other than php to email me one to try it and see if that fixes my problem?

It does, there are several vendors that support Hydra, or vice versa depending on which way you look at it. Tony Wildman and Gearhead are 2 of the best/most popular.

If you have the optional USB cable, you can use it to read the current PCM calibration. If you email me the calibration I can put the PATS information in your current file and send you a new one.

Connect your laptop to the USB cable with the chip attached to the PCM. Turn on the ignition and select the "read pcm" (or similar ) option from the Hydraflash menu.

... And yes, VRAA6Y3 is the correct PCM code for your Excursion.
