I've been reading around and from what I am gathering this requires me to either:
-- Upgrade to a 0411 PCM and then OS Swap to 12216125
or
-- Use a P59 PCM out of an 4.3 or Express VAN or something that is drive by cable
So I want to ask:
-- can I get a part number or specific vehcile make model and year for a P59 PCM that is drive by cable?
-- can I OS swap a 12216125 in my current PCM on my 99?
-- What segments will I need to swap in either my current PCM or the 0411 PCM? I am assuming no segment swap is necessary on the P59 PCM?
-- The P59 PCM seems the most plug and play out of all of them, but is there anything I need to change or tune out? It sounds like I need to disable the O2 Sensor Heater Codes, but is there anything else?
-- Is there any re-pinning required on either PCM?
Lastly as a Bonus question, my LS3 knock sensors are installed but tuned out because they're throwing false codes. I am believing that the LS3 knock sensors need to use a different pin than my original LS1 knock sensor, does anyone know what pin that is?
