i got a used fc and the commander screen just sits at the apexi logo when i turn the key on.. i need to find out if its the ECU or the commander. or the connection. i live in Brenham tx which is between houston and austin and about 30 mins from college station/bryan area if anyone can help me test it i would be very grateful,

 

Hey man, have you tried unpluging and pluging back in your commander to your PFC? I think your symptoms are those of a loose connection. Hope that helps....

 

yeah i tried wiggling it and removing it and putting it back.. pushing it in harder all kinds of things. i dunno what to think

 

alright i fixed it. was the brown wire in the commander needer resoldered. thanks for everyones input
