S.Trim Freezing

Post by 2x0 » Thu Aug 09, 2018 3:15 pm

I’ve had this problem quite a few times now, normally after a longer highway drive. I’ll stop at a stoplight and notice my AFR go lean. I check my s.trim on my phone and it will be stuck at some random number, today was 1.56%.

I made it home but it wasn’t adjusting s.trim anymore and my AFR was very lean. Once I turned the car off and back on it started working properly again.

I’ll try getting a datalog when I can, but it’s random and I don’t drive around with my laptop plugged in. Is this a common problem or any ideas what might be causing it?

What is the serial number on the s300 board inside the ECU?

From Help, About, what is the version of software you are using?

Has J12 been cut inside the ECU?

Post your calibration as well as a datalog showing the issue.

Did you ever get this sorted out? I've been having the exact issue.
