Link not working anymore. Mind reposting?
Is this specific to FA20, or will it work on EJ as well.
I found some similar things in opensource, but sometimes it didn't always translate back and forth.

Anyone with good information on tuning for EBCS. On my last platform you started by reducing the waste gate duty cycles (by half) and starting from there.

Hi Bill,

Could you provide the codes to delete the CEL for TGV deletes?

Thanks in Advance,
Scott

So I finally got my TGV deletes reinstalled, found the proper ECU codes to turn off and copied over all the open TGV tabled to the closed TGV tables. P2004, P2006, P2007, P2009, P2012, P2016, P2017, P2021 and P2022. (The High Circuit code can probably be left alone, but I didn't take any chances)

Here are some logs I took today.
Log 1 on Data ZAP Me

Log 2 on Data Zap Me

My current mods are:
ETS Intake with Box
ETS catless TBE with resonators in the J-pipe and mid-pipe. (could be a little quieter for my taste. I may swap out bigger mufflers for the rear, time will tell)
TIC TGV deletes
Mitsimosho TMIC and charge pipe

I have a GS 3 port and GFB BPV ready to go in but first I'd like to hear some feedback back on the fine knock learn I'm experiencing at the end of the logs... usually from 6100 RPMs to 6500 RMPs. -1.41 on the first log and -2.11 on the second log.

This causes the car to stumble a bit as timing is pulled to address the fine knock learning.

The car feels strong all the way to the 6k then I get the stumble for about 500 RPMs and goes away. Boost error, A/F, Fuel pressure, dam and feedback knock all look to be in place and well within tolerance.

What can I do to tune this out to keep knock away and Ignition from dropping, ultimately causing my stumble?

Cobb, do you have any feedback or recommendations?

^ your getting knock from too much cylinder pressure up top. Back the boost down near redline. Check out TD error near there. It's pulling almost 1 to 2 PSI up top. Lots of osculation too.

* not very familiar with 15's. Using knowledge of 2.5 here.

I'm working on tuning my three port and was trying to use this XLS... Your instructions state "to create a pivot table in excel that plots your percentage of boost variance across RPM and Req. Torque." Can you please provide some details on how to do this?

Thanks

Fantastic thread, I hope this continues to grow. Here is a great thread on how to tune for TGV/EGR deletes:

FYI, I've been self tuning for years mostly been in the mitsu camp (DSM/EVO), this is my first drive by wire and DI car, so some of this is new to me.

Couple questions:

1) Any info on how to make the throttle more linear? I would assume it is in the target throttle angle map. I'm currently looking at the cobb base map "Stage 0". It really seems to be spread over two maps from what I can see (don't have Cobb in front of me). Pedal to request torque and requested torque ratio (?) to throttle angle. What is requested torque ratio?

2) Also I am looking at trying to tune the boost curve a bit, Back in my EVO days I would turn off all the corrections, get my WG duty cycles where they are needed, turn back on corrections and then adjust the temp comp table to keep things under control with the seasons.

From what I can understand now, Throttle gives us requested torque, requested torque gives us target boost and WG duty cycle. So this seems pretty strait forward but are there a gear dependent adjustment? Can I shut off corrections to help get the WG table in check?

Thanks in advance.

I am also curious how to go about tuning the turbo dynamics tables (in my case running a 3 port ebcs)

I just got done tuning my GS 3-port... I only had to adjust my high and low waste gate tables.

I may be able to get away with that, but I would like to also understand the turbo dynamics tables fine to it. Thanks!

OT. Has anyone gotten this error when installing the Accesstuner Race? Looks like the file in the install has a extra _B . I have a 2015 WRX 6 MT. Your help is appreciated.

Make sure you have updated your AP first.

Anyone have any suggestions on tuning the maf corrected volume? I am trying to get the maf calibrated for a different intake? Also, how a/f learning 1 is reasonable to see once dialed in? Thanks!

sir Stevo
I have an 2015 FXT, EBCS, Catted J pipe and an ets intake ( supposedly no tune required. )
i lowered my WGDC by 40% at what point do i stop when raising them back up?
when it overshoots?
What other tables are in play here with the EBCS soemone said turbo dynamics but which are applicable. Integral Neg/Pos seem most applicable. do i reduce them by 30% as well?
What will the catted J effect? AFR? Spoolup?
Is there a way i can log an already tuned map to copy parameters? I have a map i like BUT it seems to be a low boost high timing tune. my dam drops alot at low speeds 2100 rpm no feedback knock though. im wanting to use the Cobb ots tune and modify it for my parts.

What's going on, everyone!

First off, thanks for all of the amazing info and contribution to the thread/community!

To make a long introduction short, and getting to my point, I was wondering if there's a guide like Psyko's (or maybe he's already taken care of that ) where I can build on Cobbs' foundation course with EFI?

I recently purchased and passed the course, done the super small things like disabling the ECU codes for TGV/EGR deletes, but I'm looking to learn more (within the community), like if you touch Table X, it will affect Table Y & Z.

Again I'm not making any sort of demands from anyone; you guys are truly amazing.

Just looking to see if something of the likes is already published for our platform?

And yes lol I know I can always pay a pro-tuner, but I would hate to spend X dollars a 2nd time around and not learn much in the process.

Appreciate the support & help.

Check out PhatBotti's website, they have links to NASIOC threads that will help. Look at their FAQ.

Don't have enough reply's to create my own post, but does anyone still have a copy of the FA20DIT Calculator? Just installed a new fmic and I have to rescale the maf as the car isnt driving properly. The car is pulling major negative trims and going afr's are really rich.
