Flex Fuel P01/P59 Service

This is a service to add Flex Fuel functions to your existing PCM whether this be remotely or in house here. There is also options for mail order tuning and remote tuning to be added on with the Flex Fuel Service. This way you can have us setup the basemap for your combination with the Mail Order option or have us fully remote tune, pending you have HPTuners and a quality Wideband (not AEM, Glowshift, Innovate etc). The widebands we prefer to use remotely are the Ballenger AFR500 series or any of the ECM widebands. These must currently be analog based widebands to read through either the EGR port of the PCM or the Pro Interface of HPTuners. These P01/P59 are serial comm bus controllers so CAN based widebands will not work.

Please note that only certain vehicles are capable of Flex Fuel using the P01/0411 PCM. C5 requires the use of a P59 PCM to make everything function along with Flex Fuel.

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
