JB4 Install: All of a sudden 29F2/2B2C Codes!
I installed my JB4 and ran fine for about 72 hours. Now I throw 29F2 and 2B2C codes after the engine is warmed up and I hit 3k RPM.
This happens regardless of what map I set it to, and did not happen when I was driving the car hard. I've tried adjusting the open loop settings (Speedo 11) and adjusted everywhere from 60-100 with no luck and the same results. I've updated the firmware on the JB4 to the latest firmware as well. Worst part is, this even happens on Map 0 with the JB4 disabled. Can anyone help? Any ideas? |

Have you reinstalled the JB4 yet? Does the car throw codes with the JB4 uninstalled completely?
Has your car had the HPFP replaced? Are you using E85 in your tank?

I haven't tried to uninstall completely. I did attempt to reinstall. I'll try that next.
HPFP has not been replaced but it showed 0 signs of stutter or any other issues prior to this (63k miles). The car would turn over on ignition faster than any car I've owned. No e85. |

My Hpfp went out right after I installed a piggyback. Was difficult to figure out what had happened.
