@E90Company, what's the history behind this? I have been plagued with oscillations and was unaware of any maps made to fix it? Is this homegrown or officially from COBB?

Either way, thanks for uploading, def gonna give this a try

Why didn't you ask for some help?

@Jake@PTF has been working with me for a year now off and on trying to iron things out. My car seems to have extremely unhappy wastegates.... and a terrible timing curve, maybe related maybe not. I sent this map file to Jake, hopefully using this method will work...

FWIW, I have newer coils, plugs, injectors, and just did a walnut blast 3k ago. I have a coil of new vacuum line sitting on my workbench, thats on the to do list for sure.

Ah ok, This wont be anything that Jake hasn't already tried.

Yeah that's what I figured, but at this point I'm desperate.

Piggybacks never had the issue which is frustrating.

so why not stack jb and fix your timing issues and most likely your boost issues as well

Honestly never looked into it... I'll have to do some searching to get educated

@Zasquatch, The changes I made are much less than a custom tune by Jake. This is a scale down of the WGDC base table and the stock D-factor multiplier (less harsh than the OTS) which seems to clear out 80% of people oscillating and overshooting boost. If Jake is having to take a few revisions to get it right this probably wouldn't help much, but anything is worth a try. These changes gave me a very predictable, smooth boost curve and my turbos are new. On the regular OTS maps I would overshoot my target causing minor throttle closure and some oscillation at boost onset, which is what most with new or low milage turbos experience and need to make these changes themselves.

Zasquatch,could you post some logs of this oscillation and timing conundrum or a little more details of this,have you tried some race gas or E85 mix to see if this helps things timing wise?

Just got new maps from jake and so far much better feeling. Ill take logs tomorrow hopefy, but won't post until we straighten it out since jake has a business to run
