    Default Long term memory perfomance ECM

    Is ther anyway to remove this light it constantly stays on? It annoying

    I get a long term memory performance code even after i just flashed my truck? I thought it was from the battery being diconected all the time but its been powered for a while

    Is there a connection between the security light and this? As the light always is on in the dash too

    My RR ecm works fine I can read/write no issues and the code doesnt seem to harm anything.

    I have the theft set to diabled in G301

    Is this on your RR LB7 or a real LB7 ECM?

    Thanks that is what I needed to know it was on my roadrunner Ecm

    Now how do i get rid of the security light? I think i read somewhere that you posted the lb7 would do this.

    It doesnt seem to effect anything besides the big light always being present
