FAQ - GM and EVO-ALL Hardware 5 Programming

Question

This only concerns newer GM vehicles when the EVO-ALL does not want to program.

 

Problem: Evo-All with hardware 5 ONLY does not program. Harwdare is written on the back of the EVO-ALL on the top right corner of the sticker.

 

Solution:

Three possible solutions:

1. Change the Evo-All for a hardware 4 model.
2. Install a 50K pull down resistor on the Red/Blue wire of the Evo-All. (one side to ground, the other to the Red/Blue wire)
3. Flash to firmware 4.07 and tie the Lt.Blue and Red/Blue wires of the Evo-All together.
