    So, changed my stock head pipes to V&H true dual headers, Also took off the Power commander II and the factory ECM and replaced it with a Thundermax with Auto Tune. Bike runs really good now....good acceleration, no decel popping... but now I have a check engine light.....any ideas as to the cause of the idiot light??

    Got in and got the codes and cleared them.... I have codes: P0131 and P0151.

    not sure chris.......hope cardboard or hrk will see this.....they seem to be pretty good with the efi stuff. i feel the light is of a code that hasnt been cleared. probably not a problem with the bike.

    again, welcome home and congrats on the promotion!!

    I believe those codes are related to the front and rear oxygen sensors.
