It's been 3+ years since my car was pro tuned 2008 - e92 335i stage 2+ 93 octane, lately I was smoked almost by an s4 not sure if it was stock anyway don't matter. I have no error codes but I just re-flashed my car with the pro tune map again and getting timing pulled on all cylinders. How much timing pull is safe can someone help me out and look at my pull 1st 2nd 3rd and 4th gear pull. THANKS!

good lord this is a large thread, i am experiencing the same exact issue with the same exact ecu and map IjE0s stage2 agg + fmic st throttle v402 getting the P2ABC/P3100 prior to these codes i got P30FE , went ahead and cleared the P30FE and consistently get P2ABC/P3100 on hard pulls there after, im going to try changing the tune back to just stage 2 non aggressive and see if it does the same, i put the car back to stock and did not get codes which leads me to believe its tune related, i plan on doing a custom tune in the near future but wanted to know... if this isnt tune related , what would be causing exactly |

im on IJE0S, but question that just came to mind,
ive had the tune on the car for a few years now never had an issue till recently .. i would have assumed that if its voltage it would have been giving issues since day 1 .. no ? - to remedy the issue i installed the new NGK plugs and some coils it went away for a few days after i uninstalled the cobb and re-installed it ( when i added 2 coils to #1 and #2 ) .. |

Hi all,
I just want yo share my recent story/situation with Cobb. I recently got some VRSF catless downpipes. I also have their 7" FMIC, charge pipe with BOV, MFactory LSD, with solid diff mount, and a gen2 HPF exhaust. I switched to the Cobb stg2 aggressive + FMIC, I also changed my plugs and coils and thought I was good to go. After a day of driving I got a P2C31 code. I have been resetting this code for about 2 months. Finally took it in to my shop. The wires were not switched on the sensors and the sensors were tested and were deemed good. One of their techs had some experience with Cobb and said that their tunes are not for catless downpipes. I called Cobb twice and spoke with Brandon and he confirmed I will need another tune that is for catless downpipes. SO, if you're gonna go catless I'd look for another tune. I'm gonna probably go with MHD. |

We must be subscribed to a lot of the same threads BQ
All Cobb Stage 2 maps have the cat efficiency codes disabled (29F4 and 29F5) for catless DPs. 2C31 is not the same thing, it's a trim code. If you're 1000% *positive* the connectors aren't crossed and the sensors are actually in their correct original locations, something else is up that switching to MHD is almost guaranteed not to resolve. Post a log for BQ to look at, one bank's fuel trims are probably all jacked up because DME is getting bad or no reading. |

Thanks guys. I will do some logs and post them. I am still puzzled that a support staff at Cobb would tell me that their stage 2 does not support catless downpipes. More to come...
