P59 Flex Fuel PCM

This is a refurbished OEM GM P59 (Green/Blue) PCM. We only stock PCM's that contain IAC drivers and analog AC circuitry so these will work with both DBW and DBC applications. They are all flashed with a base OEM file of your choice with VATS deleted. You may also purchase a Mail Order Tune option along with this and we can flash a custom calibration onto the PCM for you prior to shipping. And last but not least there is an option to purchase with Remote Tuning so that we can remotely dial in the combination for you. The PCM will come pre-loaded with our basemap to fire the car up with on the Remote Tuning option. Remote tuning requires you to have HPTuners and associated licensing to read/write/datalog the PCM with.

This is also used to convert 99-03 C5 (97-98 needs rewiring of harness), 99-02 Fbody (98 needs rewiring of harness) to flex fuel capabilities.

If you are requesting a Mail Order or Remote Tuning options, please fill out our mail order form to send in with your ECU or email with tune files. Link
