Thank you so much for doing the work on this! We need this product and I'd like to purchase two of them when they are in production.
I'm not sure if you're aware, but many of us 964/993 guys pull the relay before starting the car after a period of hybernation. Then crank several times to build oil pressure. Then re-insert the relay and start the car. It might be a cool thing if there is a way to incorporate a "kill" switch in the relay. It could also work as a theft deterrent
