Ehnto Posted June 17, 2020 Report Share Posted June 17, 2020 Howdy, as you can tell from the title I have run into some issues that I can't seem to find online, and a particularly worrisome one that shut the car off and re-locked the ECU. This is a long winded one so sorry for the long read. Unfortunately I wasn't able to save the log due to the PCLink itself faulting and needing a restart. First error, which I noticed upon first connecting to the ECU but hadn't seen since clearing it:Error Code 9: Settings Underflow It's not in the documentation anywhere, online or offline. So I wouldn't mind getting some info on that one. The second issue a lot was going on, the car shutting down and ecu relocking, a handful of errors showing up, here is the timeline: * Started logging, went up through gears 1-4, staying under 3k rpm, running rich but everything was working * Made some changes to the fuel map according to the Mixture Map automatic updates * Started logging again, got to maybe 2-3k rpm, car shut off * A program error dialog popped up saying ISC Solenoid error (I think, it disappeared too quickly for me to take a picture) * Program dialog popped up saying ECU is locked, contact dealer to unlock etc. (Maybe a red herring?) * Tried cranking, and it cranked but didn't start * Unlocked ECU again, cranked but didn't start * Error Code 9: Settings Underflow appeared again * Can't find it online, but a Fault Code for Injector Max Duty Reached * Upon trying to open a saved known working tune, I got a program error dialog about invalid memory addressing or something along those lines, again the dialog disappeared before I could record it (would be good if these stuck around or were otherwise logged, even when not logging engine data) * Turn everything off, re-connect, load known good tune (base GTST tune from Link, with initial configurations completed, master fuel set, nothing else changed), cranks and starts perfectly fine. Is it possible the ECU did not actually relock itself but the dialog error was thrown improperly? I'm not so worried about the tune, it's the unknown errors and possible re-locking I'm concerned about. I think the issue with starting was because I made changes too low in the RPM range from the automatic mixture map updates and those updates were inaccurate, I forgot to double check them.

Edit: Just noticed in another thread, Fault Code 9: Settings Underflow was addressed in a firmware update. It would be nice to know what it is and what issues it could cause still.
