    Default Handheld display useless today. Will new 553-108 work or options?

    Hey Gang: Like a lot of other folks who bought the Avenger system and the handheld display/programmer device, ours has decided to get so dim you can't use it. The car was down for a few years - worked just fine a few years ago, now it's so dim you can't even read it.

    So, we either need a new handheld (have no idea as to the part number and availability), OR can we use the 553-108 display? The ECU is basically a Holley HP ECU - and we upgraded the firmware to V5 and can use the V5 software, so I believe this "might" work.

    Kind of annoying that so many Avenger users have seen this problem - to me this is a distinct DEFECT in the product that we should not have to deal with on our end. When I buy an Apple iPhone - the display continues to work for many years, I expect the same of Holley.

    Note: This is not my only Holley EFI purchase - just bought two box fulls of Dominator stuff - for a big blown application. What say you Holley? Dale

    The early style handheld controller (LINK) is now obsolete. The new style 3.5" LCD touchscreen (LINK) isn't too expensive, and it's much better!
    May God's grace bless you in the Lord Jesus Christ.

    That small handheld does not work with the newer versions, so as soon as you updated the ECU, you would have to get a new 3.5" LCD display.
