Acadia Celebrates 1 Year With MQB #3, Wonders If It's Time To Upgrade...

[Acadia18]

Given it went away after, my guess is it was indeed the traction control

You sure it can't spin? This guy has an XL but is clearly spinning tires at 90mph

I'm cautiously optimistic my only issue was the TC. I've gotten EPC\Limp Mode & P0234 errors twice now, and while TC was on both times, I wasn't going anywhere near 90mph. Just some regular acceleration on the highway\on ramps, not even WOT. Since I do have a habit of not turning off TC when I get in my car, I'll code it off with OBD11, and see if it happens a 3rd time.

And I can't say I'm 100% sure, but I don't think so? I don't feel any slippage at 90mph. Earlier, sure. But not that high. It is possible though.

It's the TC, Jon.

It's a ghost.

So here's two top of 3rd pulls I did on my way home from work today. Paging all the smarter guys than me to take a look at something.

Pull 1: https://datazap.me/u/acadia18/eqt-v...c-1242022?log=0&data=3-8-14-38-41-44&mark=101

For this pull, I didn't turn off ASR\ESC, because I don't have a habit of doing that when I get in my car. At 90mph my car said "WOAH WOAH WOAH NOT SO MUCH BOOST!!", and another part of my car said "IDGAF, YOU'RE GETTING THE BOOST!!". No EPC or anything, but I could see the Target Boost I was monitoring on my AP start to drop.

Turned off ASR\ESC, replicated the same pull, about a minute later.

Pull 2: https://datazap.me/u/acadia18/eqt-v...c-1242022?log=0&data=3-8-14-38-41-44&mark=135

Boost control was right where it was supposed to be. At 90mph, my car didn't try to pull back the boost.

That lines up with two full 3rd gear logs I did yesterday:

TC on: https://datazap.me/u/acadia18/eqt-v106-3rd-gear-log-1-tc-1232022?log=0&data=8-14-38
TC off: https://datazap.me/u/acadia18/eqt-v106-3rd-gear-log-2-tc-1232022?log=0&data=8-14-38

Is there a safety measure built in to ASR\ESC to pull boost at 90mph if those are turned on? I know I can have traction issues lower in third, but I'm hooked at 90mph and not breaking grip, at least when these roads are dry. Is there anything else that could be happening here?

I've been following this thread for a while, initially finding it for results of Vortex turbo with only a HPFP. Can anyone clarify if these over boost issues could be solved by using cobb TC instead of OE, since its ignition cut based vs. boost cut? Since that is the case, would the boost not then be cut and cause the engine to run lean?

Sorry if a dumb question, just trying to learn.

CobbTC can only handle so much before it lets loose. Winter, crap tires and a Vortex...not even Jesus can help him!

I could make an instructional video on how to wipe sitting down without getting shit on your hand, since that seems to be a confusing idea for some...

Quite the turn for the build thread. Will there be Mayo?
