So a few members have their used PFCs for sale with the Commanders, and I can use the $$ i can potentially save to get the Wideband Fuel sensor as well. THe question is I have seen many ppl ask about the SN on a power fc. WHy? What am I looking for exactly? Do you recommend buying one used?

Thanks for your insight.

 

I don't know anything about SN's but I have both a used commanded and Pfc, they both have worked for 3yrs now. Electronics don't typically go bad they die from miss use.
