Do I need Ver.4 for E85 ?

[Boosted920]

I have the Kpro version right before the built in blu tooth. So I believe it's Kpro3 ? Do I need to upgrade to Kpro4 in order to run the E85 GM flex fuel sensor ?

What is the serial number of your K-Pro board inside the ECU?

Version 4 K-Pro is needed.

i know i am responding to a very old post. i too have a version 3 kpro with a serial number of 13008 on a PRB-a07 ecu. so there is no way to use the digital connectors on the v3 board to connect the gm flex fuel sensor? thank you

No, you must use the v4 K-Pro.
