With only 11 seconds of log and no recording of idle position DC% i can only see that the engine fan kicks in once dropping you idle. Also your lambda is not tracking your target. Best to get this closer

Post a new log and file

Its not overrun cuting in and out?

Your current Map and a log file will help tech support with fixing your issue.

North Queensland. Aus
I can do dead times and max flow 98 and E85.
SPAT I can't do.

If u send me one I can do it on my test rig.

Yep 1.52 sorry. Those figures dont take into account your wiring or LINKS ECU injector setup.

Link has a good injector test function. So worst case you can work it out that way.

These are the dead time figures i found for 43.5 Psi. Any reason why you have your base fuel pressure at 50 PSI?
8v---- 1.52
10v--- 1ms
12v----0.71ms
14v----0.55ms
16v---0.43ms

Glad it works. Always frustrating chasing the little things.
Another thing to look at is the over run fuel cut settings. At 1.2% TP threshold you may find you can reach 1500 rpm with less TP% so when sitting stationary and holding the rpm up it will bounce in and out of overrun fuel cut.

In the help file type in Stepper Reset, explains 2 different ways for a reset. 5 sec hold time should be enough i reckon. I would give it a clean first so it give repeatable results.
I would also target a slightly richer AFR at idle until you get the idle sorted .95 is always my start point until i get idle stable.

These are low resistor injectors do u still need a resistor box?

My 1st thunder was the same. More annoying than anything. 2nd is about .2 out. Just make sure voltage doesn't drop when ECU internal temp rises.
Is there a voltage difference between bat voltage and aux voltage.

Is 9600 baud normal? I looked the Link USB Com port settings on my laptop and it's 115200 by default, but I'm not currently connected actively to a ECU at the moment and about an ocean away from one.
In regards to Integrated graphics vs the geforce gpu, in my experience it doesn't really make a difference. The Intel integrated is a pretty good gpu for what PCLink ask of it. But if you want, you can change the affinity for PClink by going into NVidia Control Panel, then Manage 3D Settings, Program Settings then choose PCLink or Add it if it's not there and you can choose which GPU to use for it.
Not sure if 9600 normal, will try 115200 cheers.

Always recommended to do a file compare after software upgrades to see any possible changes.

So after fixing that im now at 60hz and dropping down to 31hz when logging. Still pretty poor tho. If i change the logging rate from 40hz to 20hz the sample rate increases to 43hz.
Is that a ECU limitation?
-
So i think think might be because this dam PC keeps using the Intel graphics instead of the geforce GPU. No idea how to stop that atm.
-
Thanks for the quick response guys. PC im now using is a ASUS ROG scar strix 3 with the RTX 2060 so should have no issues there. Hope the below pic helps. Also happy for anyone to remote logon and have a play around.
Not sure it it makes a difference but i have both CAN 1 and 2 channels full.

Enjoy your holidays, this can wait as its not urgent just annoying.

Any idea why the software sample rate is so dam slow. Not sure if it is a usb driver issue or a limitation of the ECU. Sample rate goes between 40 and 25Hz. worst when logging.
-
Sound like the ecu has a poor power supply or ground.
Have you tried powering it up out out the car? Also make sure you don't have any CAN devices connected.

If a LINK ECU is not wired in as per the LINK help file/recommendation it is wired incorrectly. If another brand requires the injector outputs wired differently they you must follow that or again it has been wired incorrectly.
I've quoted it again, please read it slowly this time.

I can totally understand your point here, but I wouldnt call it "wired incorrectly" as there are a number of different ecu manufacturers that actually recommend that you wire the ignition/injection out puts in the firing order. Say with a 1-3-4-2 4 cylinder, out put 1 to 1, output 2 to 3 and so on.
As long as the installer and calibrator know whats going on it will work, it may just create confusion for others down the line.

owww.. that's right.. i thought that is no firing order setup.
I just find out, there is in the configuration set up..
Thank U so much.
Since the engine already working just fine.. is it ok if i just leave it like this?
Having it wired incorrectly will cause confusion when trying to configure knock control.

Your dead time values are incorrect.
What dead time values are you using? You should be looking at IDC% to see if injectors are maxed out NOT the 150 number in the main fuel table as there are so many variables.
