Hi guys,
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
When there is a loose wire or there is short cirucit you will not notice this on the log as the device immediately turns off.
I add some more info to the log for next build that allows better diagnosis of reset cause.
I loaded my V2 again yesterday . No cut out .Runs perfectly. Is it possable that a cam trigger is failing
could you please post also v2 base map ?
Hi Jadzwin see my file saved today with today’s log of v2. I see my log file is 12mb to big to upload

Please set up digital inputs like that:
Also I can’t see any configuration for vss sensor in V2.
If you want to have vehicle speed just use the speed from abs:
Please disconnect the VSS sensor, make above changes and it should be ok.
I’ve testes your calibration on simulator and didn’t find any issue.
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
