I have been working on this problem and have finally found a way to playback a recorded onboard datalogging that will show analog input readings.

When a onboard data log is recorded to the ecu I click on ( Download from Ecu ) then double click on a recorded data log to view the data log.
The ...

As far as the onboard datalogging it is just recording the normal engine sensors of the vehicle.

The only issue is there is no data being recorded for the installed oil pressure sensor during a onboard datalog recording.

I have a switch to activate onboard dataloging. When a switched activated ...

Any idea’s for a solution to this problem?

Software version 2.8.9.0

Serial number - 60855

I have a oil pressure sensor wired to A0 signal - B2 LG2 ground - and D19 5v

The oil pressure data reads perfectly when viewing the live data on the laptop

When on board data log has been recorded and downloaded to a laptop for viewing - all sensors of the vehicle read as perfectly as expected ...

I am getting this same problem with Smanager. I’ve even had it error on reviewing a datalog unplugged from the ecu and tried 2 different laptops and it still will pop up an error message and close Smanager.
Is there going to be a Smanager update to fix this problem?

I see in the picture of the pins how you mentioned that one looks damaged and have a through hole. I inspected that pin and there is no damage or solder cracked or broken. I resoldered that pin just to do so and made sure j12 was cut and not contacting.
There was no difference made. All the sensors ...

I have narrowed this problem down to the switch control datalogging. Every time when the switch is turned on to datalog everything starts to go crazy all the numbers start maxing out for sensors on and off also error codes start to flag up to 16 error codes.
I have tried another switch and wiring ...

I have changed the capacitors in the ecu - no diference made

The problem seems to be getting much worse

Attached is a datalog that is just a complete mess of everything going on.

Has anyone ever seen this before?

Thanks for the info on the ecu capacitors.

I would have never thought they could caused ecu glitches because of there age.

The capacitors have never been changed.

I see no signs of leaking or swelling of the of the original capacitors on the ECU board.

The serial # is 22305

The software version is 2.7.8.0

I have been having an issue with a hard engine stumble at light throttle and mil is set with many dtc's for a very brief moment
Also there have been a few times where it keeps wanting a firmware update when uploading changes to the ecu.
Any thoughts to what may be happening?

Attached is the datalog ...

It may be a couple pounds less than previous runs. I have just have never seen a flat duty cycle through a gear like that in my logs no matter the psi amount. I thought maybe something was failing in the ecu.
Thanks for viewing my datalog, good to hear everything is working as it should

The last two outings to the track I have blown headgaskets both times. This past weekend the first pass was ok no headgasket failure. The second pass the headgasket failed blowing coolant out of the overflow ...
