Title: GTRS [GT2860RS] 1.8T [AWM] KFLDRL & KFLDIMX Post by: BlkSerialKilla on October 30, 2017, 10:23:50 AM Currently in process of attempting to revise my tune for my recent installation of my GT2860RS [eliminator on stock manifold]. I checked the wastegate with hand pump and it would appear it opens at 1.00~ bar pressure and I checked with the N75 electrical connection disconnected on car and boost is around 1.00-1.10 bar. I'm reviewing the information in regards to calibrating using CWMDAPP=8 & manually setting KFLDRAPP rows to needed DC and getting a table of boost in relation to DC in each condition. However is their a baseline configuration I could reference for KFLDRL and KFLDIMX that someone has done for this turbo & wastegate?
Currently limiting boost to 18-19 lbs of boost and planning to keep it so since i have 550cc injectors and running our of DC for the initial 11:1 AFR I was initially setting for safety, Planning on using 12.06 or 12.5 . Also I made the following maps like attached. Yes in the future I do plan on building a block and getting full potential out of the turbo; Rods at very minimum.

1000 mbar pretty useless if youre planning to go higher and why not 95% during spool up? also check s4wiki for tighter wastegate settings Title: Re: GTRS [GT2860RS] 1.8T [AWM] KFLDRL & KFLDIMX Post by: BlkSerialKilla on October 30, 2017, 05:40:34 PM you should rescale kfldimx axis 1000 mbar pretty useless if youre planning to go higher and why not 95% during spool up? also check s4wiki for tighter wastegate settings I had initial concerns since I have not replaced the rods no kidding the stakes I've setup with this setup almost make it not worth it :( Title: Re: GTRS [GT2860RS] 1.8T [AWM] KFLDRL & KFLDIMX Post by: vwaudiguy on October 30, 2017, 08:52:08 PM I had initial concerns since I have not replaced the rods no kidding the stakes I've setup with this setup almost make it not worth it :( Just don't floor it until like 5-6k and you'll be fine!

I read over this thread http://nefariousmotorsports.com/forum/index.php?topic=9221.60 and had made adjustments to KFVPDKSD and KFVPDKSE appeared to be 1:1 so I mirrored my alterations in each. I used log from running wastegate spring pressure without n75 plugged in and determined what would basic boost pressure as FR mentioned and rescaled PR axis to accommodate new PR @ 2.0, advanced columns 2-10 over to 3-11 and placed first column data into second column. I'm going to log this tomorrow morning and review. Am I looking at this correctly though? |
