Hey guys,

Firstly the platform I am using

B7 1.8T
8E0 909 518 AR
K04-0015
Bosch 550cc EV14 Injectors
Stock MAF

I had my car tuned by a tuner some time back and since then it has always had massive timing retard (-9cf). I had asked them to sort it out in the past and they tried but could not figure it out (This was when it was on K03-0029). Since then I've done some changes and have been using an MBC in Parallel to keep boost spikes away as the Wastegate on the K04-0015 is crazy and I get 1.6 Bar when using the N75 alone (I've since adjusted it on the map I'm working on and I seem to have got it working just fine) but I still have this crazy timing retard and I can't figure out why (Perhaps I'm just not understanding something, perhaps it's torque intervention) so I'm calling on the assistance of the forum members to advise me in where I might be going wrong

I also have weird AFR spikes and stuff.

I used Master J's spreadsheet to calculate and scale KMFIOP

I've also attached a log of before I tuned WGDC and after.
*Edit : Did a PS_W log and I seem to be hitting the cap early on, could this be the reason?

I'm new to all of this and still trying to get an understanding of how it all works. I've posted logs and stuff below.

Hence me trying to fix it myself. I've actually got another set of logs where timing retard is -10 :/ I've uploaded the CSV.

The weird thing for me is that lean spike at the beginning. Also I've tried using TABGBTS set to 200 and using LAMBTS to force the fuelling to around 12 AFR in boost but it isn't working all too well for me. Even removing timing from KFZW does nothing much. I'll figure it out eventually. I'll do some adjustments to LAMFA and see what it does and report back.

For now I'm using Methanol Injection as a band aid

Haven't done much with KFZW2 yet, I'll have a look.

Thanks for the assistance nyet, much appreciated.

Thanks Mocke, let's hope this pans out, been pulling my hair out for the past few days regarding this.

Alright, on to the next chapter

I forced an 11.85 AFR using LAMFA to see what happens.

10.5 Degrees Ign Retard, 8 Degrees Ignition Advance, and an AFR that's almost spot on 11.85

I'm a bit lost as where to look now, I also removed some timing from KFZW/2

I've attached my log, bin and xdf (Nowhere close to fully defined, just attempting to define maps as I need them, not very good at it though) if anyone feels like taking a look to see where I've failed. I've pretty much butchered this thing trying to find out why it's just not performing. (Could it be torque intervention by any chance?)

It isn't bad gas or knock sensors, if push comes to shove I'll pull the head.

The best I can do for now is to do a pressure test, I was also concerned about ps_w as I don't feel that I should even be close to the limit there.

I'll also pull out as much timing as I can and see where that takes me. I'll report back in the morning (Well, my morning which is in 7 hours time), thanks again for the advice.

Just a report back, I've pulled about 10 degrees off the last 4 load value columns (Which load value column would I use for WOT? Just the last one?) and it seems to have made a substantial difference.

Mostly 0 Degrees retard (Except when I went over a small bump), 9 Advance, 11.85 AFR all the way through.

I suppose this is the point where I slowly start adding timing back to the table?

Thanks nyet, you're my hero
