Just to close the loop on this, I've not been logging barometric pressure, in the past it looked to me that at idle the boost pressure desired was around barometric so I stopped logging baro.  I did about a dozen logs over the two week span so I would expect the barometric pressure did not remain unusually high or low consistently through that time period.

Pull timing. Also one of your O2 sensors isn't looking so good.

Do you have a wideband?

I'm puzzled by the very different numbers being shown in the Neftune5 data versus the Nef14b data that I logged.  Boost level is nearly the same, IAT's are close, yet MAF numbers and IDC are quite a bit higher (around 20%) for my car, the resultant acceleration curves are very similar.

It seems that one impact of the higher fueling is slightly greater but less varied timing curve.  If the MAF scaling is possibly the cause of the difference I do have an RS4 MAF that I could try on my car.

I don't think it is that, I'm at most driving around at two or three hundred feet.

Replace that O2 dude

Thanks for jumping in and contributing.  So I understand where you are at, did you get up through the steps summarized in this page 22 post, and this Stage 1 tune page?

This would include:

• NMAX/NMAXF
• LAMFA/LAMFA Axis
• LDRXN
• KFZW2/KFZW

By the looks of the boost profile I'm guessing that's about where you stopped.  You may want to press on and start adding the changes that I put on the Stage 2 page.  For a bit there at the end of the Stage 1 phase and shift to Stage 2 I lost track of the sequence that additional tables were being changed.  There are probably a couple of tables, like KFMIOP, KFLDHBN and KFMLDMX, that were altered in the Stage 1 phase.

I need to compare notes with therealnap0le0n and make a post summarizing all of the changes made thus far.

Looking at your csv file it looks close to what I logged at that phase of development.  I noticed in the csv header that you have the Bosch MAF, and interestingly the MAF and IDC curves in your file are more similar to therealnap0le0n (Bosch MAF) than mine (Hitachi).  The only odd thing I noticed on first look through was some small intermittent spikes in both O2 sensor readings.  Nice job incorporating all the changes, nothing sticks out to me as being offtrack.

I should note that my chassis is a B6, with a 2.7t swap.  It might change some values somewhere in the car profile of ecuxplot but I have not made those changes yet.

FlyBoy: that's exactly where I'm at as I wanted to get some real logs before pushing it further.  I have some "before" logs of 4 pulls I made on the stock modified M box file that daz provided on page 3 if those would be of interest.

nap0lean: I will be pushing forward with this, I still have all 4 cats and stock dp's but straight back after the cat's, which I don't think qualifies me to move to stage 2 just yet, so I'll be working on the stage 1 for a while.

I will make those changes on your stage2 page and get some readings.

*edit* I just had a look at the stage 2 changes and referenced my bin, I think I'm going to need nap0lean's input if those tables are related to MAF, considering my values are very very different from Flyboys who has 0's in lots of the cells.  I will keep reading as I have been doing and catch up on these changes and what they actually do, maybe it will all "click"
