A different PCM wouldn't work, IF the BCM isn't sending the ignition signal. If the BCM is failed, or is failing to send the signal, for whatever reason, it won't matter which PCM you are using.
I'm not familiar. If Banks is selling it, especially as an upgrade kit, their name is on it, at least in part.Have you ever seen the supplier that is on the decal? I am wondering if they maybe did programing for Banks?
I will try and find some info on them.Plus check out the BCM
Definitely check out the BCM.
