Once the device is removed and codes cleared(if any) is there any trace left in the Porsche ECU of the JB4?

Can you log on the device to see if there is any knock happening to verify the tune # selected is safe?

Do you know if the 718 has wideband or narrow band from the factory?

I see mention of running more ethanol, does the factory ECU have an ethanol sensor to make adjustments ?
You can email me directly if you need to

No trace when removed, as you stated.

Yes, the JB4 has logging which you can do from your laptop with data cable or phone via Bluetooth add-on. That's how we can monitor fuel trims, AFR, boost, timing etc.

IIRC, this would be a wideband. Terry would know better, so I'm not 100% on this.

No, we will monitor fuel trims, fuel pressure, and AFR with ethanol blends to ensure it is safe and can keep up with the mild blends we are mixing in.
