Need help with MHD Log
Hey All,
I recently tuned my 2011 135i DCT with MHD Stage 1 and just did a log today; Ambient temps were roughly 90 here in jersey and it was a 3rd gear WOT pull. There seems to be timing corrections on all cylinders besides cylinder 3. And my boost seems to be under target. I am new to reading logs and was wondering if someone with more experience could chime in and see if anything is abnormal. I have not changed my plugs or coils yet and I have had some stuttering in 6th while passing on the highway. Mods to the car are: VRSF charge pipe Berk race axelback K&N filter (I know not really a mod but still haha) Any input is greatly appreciated! Thank you My log: https://datazap.me/u/aaronfitz/log-1...38;data=3-4-11 |

I'm not a pro, but it looks like a possible boost leak to me. What octane are you running? Check all your connections visually before you go spending money on a pressure tester. I've seen quite a few reports of the bottom meth bung plug coming undone recently, check that also. Did you move the o-ring over from the OEM CP to the VRSF CP when you installed it?

Seems a bit early to me... I would try to catch it on a log and post it up. Also, did it start sputtering immediately after the tune? Was it doing it before?

I never noticed it before the tune only after, I'm going to try and catch it on a log tmr and also maybe flash the car back to stock to see if the sputtering goes away
