    Default Holley EFI V5 Build 110 Complete File Set - 3.5 Touchscreen Issue

    Hello. I'm having an issue with the new V5 3.5" firmware update, hoping someone can help me with my problem. I downloaded the updated firmware into my 3.5" touchscreen & Dominator ECU. The problem I'm having is with the touchscreen. On the Air/Fuel ration screen, I'm able to read i.e. AFR, Closed Loop, Learn, Closed Loop Status, RPM & Oil Pressure. However, when I switch to read all the sensors the Battery is reading TPS%, CTS is at zero, TPS is reading MAP! There's a red dot flashing in the upper right corner of the screen. Any comments or suggestion on what I'm experiencing?

    The EFI (laptop) software, ECU firmware & touchscreen unit must all be version compatible (LINK). If so, contact Holley Tech Service (LINK).
    May God's grace bless you in the Lord Jesus Christ.
