Any thoughts? rl_w went from 220 to 290 on the same tuned file, just with 5120. rlmx_w is still 220, but rl_w is about 100 higher. Car runs 2 points richer as well (which I assume is because of the inflated rl_w). I'm just getting started working my way through, and must be missing something.

Considering you only posted one log, it is going to be awful hard to figure out what changed.

My bad. Here's one before 5120.

Totally different requested boost, totally different WG profile, totally different actual boost (complete with chronic underboost), completely different MAF readings, completely different load.
What did you expect?
Also guessing totally different i limit, but you didn't log that.

They are in diff gears. I don't (yet) have one with it in the same gear. Only changes (I believe) between these two files is 5120 related.

I'm baffled as to what "problem" you are trying to solve here.
Maybe you should worry that requested boost isn't anywhere near actual first?

I was under the assumption not much would need to be changed when going 5120. Attached graph is of the file before going 5120. Request and actual look ok.

Even though charge pressure is lower, rl_w is through the roof after 5120. 5120 boost profile is a combination of running rich, higher gear, no imx trims yet, and timing because of the exaggerated load.

Guessing combination of IAT difference and one or more unscaled rfagr calculations that nobody has investigated yet...
I'd just tune around the differences.. otherwise you'll end up having to log the entire req load and load->boost conversion path to find the missing scaling.

I thought about that. My part trim went -10+ so I can bring krkte down to probably get it to where it was afr-wise, but I didn't want to do it that way. I'm convinced something is missing from the 5120. I also figured with all the 5120 talk on here, someone must have noticed the same (assuming my 5120 is correct). |

I didn't but I confess I didn't do a apples to apples comparison on the same car with 5120 vs not 5120. I just tuned 5120 files every time from scratch more or less on each car. If you really want to figure it out, i'd start by logging all of the req load path or the load to boost path and looking for differences. I'd be glad to help if you manage to get good logs. A big problem will be controlling for IAT and such, since that alone can move things around quite a bit. Unfortunately, my car is still dead so I don't have a way to log for you If/when I get it back I can try a 5120 conversion on my file and see what happens vs stock (i'm not currently running 5120 on my own car) |

Thanks for your input, Nyet. I'm going to try and tune around it for now, and see how it goes. I saw in another thread someone mentioned using your "5120 base file" so I thought you had something out.

0A 51 to 85 28 at 0x50926.
At least I noticed that different between my RS6 5120 conversion and whatever public M-box 5120 file.
That's "10.13 [hPa/%]" multiplier on page 289 of FR.

Just throwing this out there are you using a definition file that is modified for 5120? That can throw values out of whack.

rl_w is supposed to stay the same. |
