    Default V2 to V5, update 5.7" TSLCD?

    I plan to update an HP installation from V2 to V5. I don't see firmware/software to update my 5.7" TSLCD to V5. Am I missing something?

    The old 5.7" TSLCD (which is now obsolete) it's not compatible with V5 EFI software/ECU firmware.

    Hmm....too bad! What's the latest firmware it's compatible with? V4?

    Ya, good luck. I had issues with V4 and the 5.7". Holley would not help out. It sucks they just abandon the people who have a 5.7" TSLCD. Least they could do is give some sort of credit towards a 7" Digital Dash if you bought one. It's real upsetting.

    Yes, V4 EFI software/ECU firmware. It's on the Holley EFI Tech Resource Library webpage (LINK), under "Holley EFI Digital Dashes".
