How do I remove pcm?

**ls1monarch** · 04-19-2008, 02:59 PM

just got pacesetter ceramic headers and ORY. Have FRA, K and N, High flow lid, port n polish MAF, Port n polish TB, Tb fluid relocation thing, and exhaust cutout. Everything was fine untill the headers and Y pipe because of the o2 sensors. So I am going to send the PCM to LSX tuiner. Any where i could find instructions on how to safely remove the PCM to send it to them? also any HP estimates? 99 ss m6. any bottle necks in my mod list? basically just looking for airflow stuff at the moment. but open to all suggestions.
thanks guys. and girls.

I removed mine to get wires through the grommet under it. I just disconnected the battery, loosened the bolt on each connector (doesn't have to come all the way out), then unplugged the connectors and pulled it out.

Be sure to pay SPECIAL attention to getting the rubber gaskets seated correctly when you reconnect the PCM to the two harnesses. Quite a bit of water can and will get in there if those gaskets aren't seated and will wreak havoc on things! I learned first hand...
