Do you know of anything that has support for the 2022+ VB WRX?
The only things I see on the market are COBB and they do not have an options to edit/write the tune yourself. You have to pay a dealer...

Here is the tune I currently have if someone see's something obvious....

Small update:
So I put it into open loop with Speed Density and tried to get fueling relitivly close in the idle areas. Got the idle in park a lot smoother, albeit with a little bit of oscillation...

Another update!
I figured out why the e38 ecu was not following minimum air tables or changing the tps or adding or removing air with idle rpm.
The fix for the computer not controlling the TPS or...

Update: I tried those changes and it was even worse :(
So I decided to start over with a stock tune, and redo the VVE.
Now I have idle fueling tip top!
And with the truck in SD mode, it idles...

What settings are you referring to?
These are the factory values, I have checked over factory programs and the map sensor offset and linear slope are set the same to other factory tunes....

thank you for your timely response, I however have a question:
I have already gotten VVE doing good with open loop and an external wideband, I will gloss over timing; I have tried lower timing...

Yes, I have used the search function.
Yes I am read the guides and watched the videos and thought I had a good understanding of what is going on with the idle routines for these trucks.
I just got...

If you are looking to trigger/output a voltage at/above a specific RPM value, try making your own circuit using a cheap ebay shift light. First set to whatever RPM you want. Then you tie into the...

I have changed the displacement from one engine size to the other a few times, but its all been on p01 computers and operating systems. I have a tune for the truck that runs really well partial...

Okay I will do that, no problem. Thank you for replying.
I have gotten much bigger cams to idle with stock programs before, I thought something may be up.
So on my list to do ive got:
-Clean...

I have tried following the sticked guide on how to tune the idle but nothing is the same/working like the guide says it should.
I am still on step one after turning off all adaptive idle spark and...

Idk what is going on with it tripping abuse move for the trans, but I did like you said. put auto trans back to 4l80e, and thneim going to delete the DTCs that...

Okay so I swapped out a fuel rail with a service port to watch fuel pressure, look great.
So disable abuse mode huh? and "Manual trans option" OK, I will put that back to auto, delete DTCs and try...

Hey guys, apparently I don't know what I am doing so I am trying to get some help with getting this thing running well enough to do some VE tuning.

Engine: 364 cubic inches
Flat top pistons...

Okay so new problem, Flashed it back to stock and now I get the error of "Unlicensed vehicle" When I have definitely bought the credits for the tune file and the ecu multiple times. I have tried...

I have No idea whats going on with the fuel trims here.
Can someone give me some insight as to whats going on?

So I replaced MAF and got ahold of another 4.8 truck and compared readings, MAF is good. Smoke test is good. Not a vacuum leak but maybe bad injetor? Or low Fuel pressure? (Or O2 SENlSORS are reading...

Anyone else take a look at my logs and see if you can tell if it was a bad MAF. vacuum leak or bad injector....

Nah, I am going to exchange my current MAF for another one but I am still going to keep the 1BAR sd tune for now because it runs so darn good.
I will tune the VE when I figure out how, but now I...

And then compare that run to the cold/MAF tune run I did earlier this morning

Good advice man, but screw the MAF.
Engine is stock, and the changes were made by the last person?
I loaded the stock timing tables and VE tables and then set the computer to never go below 18...

The reason on why I am just so paranoid about this was because in the winter, I would start it up, and it would missfire...
