You have it rpm limit 3 times in your logs.
-
I start with 1400 cold and taper off to ~1100.
2nd reason to run ~1100 is to keep my oil pressure up when hot.
Are you running ej25 series block ?
-
Seems like the shop has no clue how the AVCS works.
AVCS should not run during idle.. no point in it.. it just robs your engine of oil.
I run my AVCS GSC2 cams at 1100 as this seems to be the smmothest.
AVCS cams or not.. doesnt matter as you could run your AVCS cams and never turn on the AVCS solenoids.
Have you done a boost leak test ?

Hi.
Try chaning the "Spark Edge" to Falling.
Next check your injector Min Effective Pulse Width... seems kind of high.
Also I see you have staged injection running.. just making sure that this is what you have.. running 8 injectors..
Not that of a common thing in a Subaru.
You seem to be idling very lean.. 16-18AFR.. that might be a part of your problem as well.
-
I would assume it can but .. It speaks CAN.. but I dont have first hand experience with AIM Pdms.
-
Not sure you understood.. but from what I see in your logs the problem lies in you either hitting rpm limit or hitting speed limit.
Your Voltage is weird at times for sure..
I think the ecu works fine down to 8V. But your voltage is high .. not low.

Hi.
Log3
From what I see you are hitting a rpm limit (fuel cut) thus going lean around 7K rpm.
First instance you going lean around 6600, log shows you are still on the throttle. (could be the way its logged)
Next I've noticed your voltage drops from 14.5 down to 13.8.. Not terrible but odd. (pulley slipping perhaps ?)
Log4
You are hitting 15.7V during idle.. Thats a bit too high.
You hitting fuel cut for some reason..
First cut is due to rpm limit which you seem to hit quite often. But I cant tell why the 2nd cut is kicking in...
There is also Ignition correction at that time and I dont see where its coming from. (6.5 table vs 1.5)
Hope this helps
Ha ha..
Found it ...
You have speed limit enabled !!!!

Post your map and logs here..

Hi.
I dont have the scaling for temp but that should be pretty easy.
Seems like both fuel and oil pressure sensors are the same.
Here is the scaling that I made.
Assumption here is that the sensor is linear.
(forgot to mention that from what I've read, ecu and defi control unit need to be connected to the same groud point)

Hi.
Have you checked for cracks before and around your 02 housing ?
You dont log knock .. but if you leaning out you'd possibly be getting some knock.. if you dont.. I suspect a crack somewhere in the exhaust is sucking oxygen and skewing the reading.. all while fueling is correct.
One thing that I noted is your wastegate is acting funky..
While your boost targets are way off to your boost (thus the oscilations) you wg seems to behave very different in almost identical scenario.

Did you search by the coil part number thats on the coil itself ?
-
Hi.
I dont see anything in the log that would indicate a missfire.
Have you checked your vacuum hoses ? That would be the first indicator of a leak.
-
Re-reading the manual 5times and switching to "single" instead of "table" made me realize that there is no other way, other than read the current cell and add X%
-
Hi.
I just got my injectors cleaned and I wanted to correct the ~1% discrepancy with a Fuel Trim Table.
Assuming I want to add a 1% to FuelTrimCylinder#4 Table... from 3-10ms pulse width.
The trim table goes only up to 75.. so what am I adding here.. % overall, % of fuel table itself ?
Fuel table goes up to 150 so this looks like an arbitrary number yet it says "Fuel table 1(%)"
Fuel equation mode is Traditional.
Thank you.

Have you researched and made a plan before installing it ?
From what I see this is a constant-on pump.
I'd run this as GP output. "on if rpm above <your idle rpm -100>" with "SwOff Timer" large enough to accomodate your rpm drop.
Might want to add batt voltage greater than <your charging voltage (13.Xv?) > as AND Sw Cond 2.
(dont forget to measure the draw on your 12v pump activation cirucuit to make sure its within the ECU limits)
Hope this helps.

Hi.
Seems like you in are in -6.5MGP when the fan is on and -7.3MGP cells when the fan is off.
~44% fuel vs. 47% fuel (from table1)

Link software has a pretty good help section.
Give it a try.

Idle Issues
in G4+
I'd start with fixing your knock.
Seems like its pulling timing left and right. (even when you just rev it)
Your DBW is in setup mode.. so not sure if you aware of that.
Your IAT might be interfering as its adding fuel pretty much all the time.
Raise your Overrun De-activation RPM in the range of oprating temp.. from 1500 say to 1800 see if that help with the dips.
Last but not least.. I'd enable Idle ignition. That should help with rpms dropping as well.
Hope this helps.

Exhaust / wideband leak ?
-
Hi.
Your Right AVCS seems to be off target by quite a bit.
Could that be causing the AFR discrepancy ?
-
Plz post the map and a log.
-
Use a clutch switch or change to 2D table where you can be more granualr and use Disarming Speed.
-
Hi.
Your LC is kicking in.
Regards.
Can anyone make anything of this? - Odd idle at cold start

With EJ257 are you sure your Trigger Mode is setup correctly ?
It shows JDM v7-10
EJ's have a Reluctor for Trigger1 and Optical/Hall for Trigger2
Btw... I see trigger errors in your log..
Why CDI over the factory coils that come with Ej257 ?
Oil pump from what I remember is 11mm.
My oil pressure at idle when hot is ~34psi
