Title: b5 s4, bw k04, 630cc ev14, stock air intake, rs4 intercoolers, full exhaust, 6mt Post by: s5fourdoor on March 05, 2013, 05:24:33 PM OK guys. Here we go. I've been meaning to do this for a while.
I have most of my tune aspects roughly cleaned up, so I figured it's time to share. Hopefully I'll get some good feedback and be able to push my tune a bit further. The goal here is an easy-going daily driver with full reliability and a max boost of 21 psi. apb, stock engine autobahn88 piping kit stock bosch maf stock airbox stock y-pipe stock bi-pipes 034 k04 up-pipes (they fit perfectly) bw k04's (imported from germany brand new) stock n75 42 draft design catch can thermostatic oil cooler with 180-degree thermostat rs4 grille mesh airflow mods awe rs4 intercoolers + shrouds bosch ev14 630cc injectors stock 4-bar fpr rs4 fuel pump - bmw inline aluminum check-valve ASP 3" downpipes custom 2-1 v-band merge into milltek stainless 3" single egt's coded out rear o2's coded out jason @ amd did the physical stage 3 upgrade. he does awesome work. two years later everything is sold as a rock.

This needs works.

What looks like the first step? My initial thoughts are: fueling is a bit too rich wastegate duty cycle falls too quickly / PID isn't dialed in correctly timing is still bland throttle angle opens up too slowly super critical comments aside, the tune isn't bad. but it def needs help. i have just installed and calibrated an Innovate LC-1, so that should assist moving forward. now i have to get the ME7L + LC-1 dual-logger that Jason wrote to run, hopefully before this weekend. all inputs appreciated, tyvmia. p.s. double-check the check-sum on the file. i will stamp it safe this evening when i get home from work.

The boost control has vastly improved. I've successfully setup the LC1 logger.
The next move; I'm going to take all of the PID settings and create a summary spreadsheet for others to start with. Currently I'm doing tests with KFLDIMX, so I'll get that wrapped up and post another update soon.

The KFLDIMX table is flat and base boost is done through a "base boost level", as if CWPLGU was set to 0. This is at least true for the K-Box.

Changed KFMIRL, KFMIOP, KFLDRL, KFLDRQ2, LDRQ1ST, LDRQ0DY, and KFLDHBN to straight RS4 values and axis labels. KFDLULS disabled with constant value of 1275, although I swapped over KFTARX as well - yet i believe its never used anyways. Additionally, I scaled KFLDIMX by the K-box maximal value and then multiplied by 60. That was what I thought would be a good technique, slowly ramping the "maximal value" up and down to get the best effect. Is something wrong with this? Are there any side-effects, so far it honestly seems decent. Also, for the help of others, here is the thread you were involved with before which discussed CWPLGU: I'll go and read that now... lol. http://nefariousmotorsports.com/forum/index.php?topic=3280.0 Title: Re: b5 s4, bw k04, 630cc ev14, stock air intake, rs4 intercoolers, full exhaust, 6mt Post by: mvmtech on March 26, 2017, 03:18:51 PM Nice. :o I too am currently working on both of my 2002 S4's which are equipped with K04's and ev14 630cc, but had create an xdf for my 551T and 551AA ecu's but I'm looking perfect these tunes myself. Just curious did you ever get to perfect this setup? ???
