This was my first drive on V3, and I’ve encountered a few strange issues.
While driving, the car shuts off when coming to a standstill. I haven’t been able to pinpoint the cause yet. Additionally, the car seems to be running a bit rich on V3. AutoTune is showing that it still wants to add fuel, which seems odd.
I also noticed that the VSS signal from the gearbox is erratic—it jumps between values.
On my VE table, you’ll see a significant dip where the water-methanol injection kicks in, that is normal . However, the entire range is running rich overall.
The shut offs are cause by ECU reset. It is not watchdog reset so most likely there is an issue with the harnes and when coming to stand still something disconnects or shorts.
The signal from VSS must be erratic that is the reason of the fluctuation vehicle speed. You need to check with the oscilloscope what type of the signal is and properly configure the input.
Thanks for the respond. In V2 i don’t have this issue .Car is not shutting off. Will check the gear speed sensor. If you look at the logs the voltage stay constantly online aswell

Awsome i did this . So i see the dwell time v2 vs v3 is deffrent .I have r8 coils
Yes, a high dwell time can damage ignition coils. When dwell time is set too high, the ignition coil is energized for too long, leading to overheating and potential melting of the coil windings, resulting in failure. This can occur if the ECU continues to apply current to the coil even after it has fully charged, especially if a new coil with lower inductance is used
