Default Vibration Under Load - MHD Stage 1+ - 07-01-2019, 05:55 PM

Hey armchair tuners,

I've been having a vibration issue for the last several thousand miles, and I'm trying to solve the problem.

I'm running MHD Stage 1+ on my stock 09 535i with 100k miles on it. I replaced injectors 20k miles ago (index 12 $$$) and replaced plugs and coils 1k miles ago (NGK plugs, Eldor Coils).

My issue is a vibration/what feels like a misfire under load in 3-6th gear.

I did a 3rd and 5th gear pull today to see if I could gain any insights (or if you could).

3rd: https://***********/u/reeselightning/...og=0&data=2-22

5th: https://***********/u/reeselightning/...og=0&data=2-22

Anyone mind offering me some words of wisdom based on what you see in these logs?

Thanks for reading!

Ummmm, couple of things. MHD, maybe contact them for support as this site is mainly for JB4 users.
Logs are read from csv files, not 3rd party hosting.
Last , being an airm chair tuner, I would guess vibration would be due to more a driveshaft, u joint, axle, hubs, bearings, wheels, alignment, warped rotors, motor mounts, trans mount, diff bushings, etc VS. an engine problem that provides no CEL or SES light.
Good luck.

Thanks for the info - Now I see that there's no info related to MHD on here. I think it may be safe to assume that it's an issue that is not dependent on the tuning platform. I've attached my logs in the proper format (I think). I'm fairly sure that it's either fuel or ignition, but it could be something unexpected, of course.
