Creating a basemap for a 2017 Subaru STI in COBB Accesstuner. Injector scaling and other tips.

- In this video we explore the process of creating a startup or basemap for a 2017 Subaru STI. This process applies to most all Subaru EJ powered vehicles. For this video we will be using the Cobb accesstuner pro software with custom features and nexgen capability. I know the video is long and may not be the most exciting but there is a ton of good information.

Thank you for taking the time to make this video! It solidifies what changes I have learned to make over the years with larger injectors! I have been intimidated by the load compensation and looks like I have no need to worry about zeroing it out. THANK YOU!
I don't always zero, but when the fuel system is working correctly, ZERO AWAY!
Here to learn some good info.
Glad to have you as a subscriber!
@@WT4T thank you and I didn’t know you did all this base map building and tuning. In the past I’ve been tuned by Mikey botti and Winnfield. Now I’m with BBR but I’m looking forward to more videos and I’m going to look through your channel for other videos. I went from Cobb to Ecutek and now back on Cobb.
I don't etune much at all but I'm the staff tuner at PREracing and have worked there longer than the aforementioned shops have been in business 😅
I wish I could pay you to give me a full walk through on tuning a Subaru. Ive taken the HPA courses and have completed them but I'm still having issues completely understanding the everything.
Email me at willtunefortacos@gmail.com and we can work something out
@@WT4T when I’m finished up at the shop today I most definitely will. Thanks brother
Hey, thanks a lot for making this video! It's super helpful. By the way, are fuel economy adjustment tables available in open-source(ecu flash or RR)? I'm thinking of upgrading 1050x injectors in my 2015 STI, and it's currently tuned open-source after installation it thinking to get a re tuned.
Not in the default rom definition from romraider but someone may have them defined in custom rom definitions
You have a video on what parametersyou log and how you set up HD viewer
I'll do one!
How was the P0420 cleared? I understand there was a aftermarket downpipe which would make this code appear.
No emissions codes were cleared. 🤗
I believe the car had an Invidia catless downpipe that we installed a GESI cat into, which usually satisfies the code parameters.
What maps from the cobb accessport could I use with 1050x cobb injectors to hold me off before actually getting a pro tune?
Depends on what else is done but if you have their 1050x map you can use that if you have sf intake but only with stock turbo.
question about data logging on a COBB AP.
Can I data log parameters with an unmarried COBB AP and make tuning changes and re-flashes with open source software?
You can log with an AP but it has to be married to something. Doesn't have to be your car. You can sometimes pick them up cheap because someone sold the car they're married to and use them for this purpose.
Jesús!? That was fast!
Thank you, by the way! 🥰
I only ask because I have a new in box AP that I bought for myself but am terrified to install in (marry it) to my car for fear that it will undo all the tuning and re-flashing work I’ve put into it so far, lol!!
How can I get a copy of accesstuner I want to learn more about running but have a protune on a motor that needs it and I just want to edit my tables
You'd have to contact Cobb and become a protuner but even with the software you'd have to get the protuner who did tune to unlock it which most just won't do. That being said as a protuner you could just start from scratch.
@@WT4T I struggle with injector scaling
During cold start my idle for 20 sec of open loop. My car will run lean about 16.xx. Once car goes into close loop, it will add 15% of fuel. Which table do I adjust? warm up enrichment , h/s enrichment, or both. Can you give me some tips. Thank you
Warmup enrich target (it's a subrtactor) just subtract what you need until the coolant temp it evens out. If its just a few seconds and not related to coolant temp then you can modify h/s and l/s enrichment
@@WT4T i'll give it a try. Thanks for your reply My a/f / short trim is lean, i will need to subract the value to have ecu, add more fuel during cold start? i thought its the vice-versa. I don't see warm up target, do you mean warm-up enrichment( non- primary)? sorry I've been trying to figure out a long time, but i can't find any info on forum. Thanks.
@sskwan1 year/make/model and tuning software?
@@WT4T 2016 sti cobb acesstuner.
@sskwan1 sounds like if it's adding 15% everyehere you should start with that. Make sure your injector scalar and latency is correct to the injectors you're using and low IPW tables are calibrated. Then make sure your maf is scaled correctly and you have zero air leaks (that will include your bov if you have one being fully shut on warmup)
May i ask what your opinion is on the cause of that weird spot in the fueling at 2700 rpm? My gd Sti has suffered from that stumble for years. I have upgraded the entire fuel system including installing aftermarket rails that have built in fuel pulse dampers. Even tried two different aftermarket ecus on top of a cobb flashed factory ecu. Nothing has been able to fix it. As i understand it the fix on the gr and newer chassis was to use the GD for regulator. So this has never made sense. I think it's great you highlighted this particular issue.
Have you watched my other videos regarding this issue?
I'm sure i have as i think i've watched all of them. I'll give them another go. Any particular vid in particular?@@WT4T

I go over it in this video but talk about it in a few others. It's caused by a combination of issues so there isn't a single fix but rather a combination of things that cumulatively fix the problem and one of those things is in the programming itself.
Yeah for my 2015, I’m using a 04 STI regulator with stock fuel lines and 1050 injectors
With that regulator you'll need some load comp or injector comp still. It's far from ideal and overpriced in the kits it comes in
How do you still have access? Isn’t it locked to one AP? Trying to figure out how people are still using it because I want to tune my 04 wrx!
I'm a Cobb ProTuner
@@WT4T Gotcha, hopefully they re-release it but it’s hard saying 😅
I know some people still using ATR, not sure exactly how but it's possible
AccessTuner has been blocked to new users for close to a year and a half now.
It'll probably come back eventually.
