Just installed the S3 Lite V2 and LSU-ADV I received (replacing a S2 Lite + LSU 4.9). Upon receiving it I connected the UART, saw that it was on FW 1.10 and perfmode was 0, so I updated to FW 1.11, SETTYPE1, SETPERF1.
The car was not running right once I installed the S3 Lite V2 (old Motronic using NB signal). It was running fine on the S2. So I got out the oscilloscope and saw this. Yellow line is WB output, green line is NB output from S3 Lite V2. No difference when changing SETPERF to 0 or 1. Tried MEMRESET, SETTYPE1, SETPERF1 and no difference (with power cycling as instructed via serial messages).
Looks like I cannot post more than 1 image since I am new to the forum.
Continuing…
Then I tried flashing it back to FW 1.09, MEMRESET, SETTYPE1, SETPERF1, reset the ECU and drove around for 15 minutes (more than long enough for the ECU to set long term fuel trims. Everything seems about right now.
That firmware is meant for Spartan 3 not Lite. On Spartan 3 the brown wire is by default set to indicate sensor temperature and not simulated narrowband.
Are all of the listed firmwares in the downloads for Spartan 3? And, can I find the proper firmware for the Lite somewhere, since I have apparently flashed the wrong one to mine?
