Good product. Looks very impressive. I've been out of the electronics game for a few years now, I'm my day discreet components had to be used in high current applications as IC components just weren't up to the task. I am glad to see they are today.
I hope you have resolved the issue of vibration at the contacts causing extreme heat. This product looks like a winner to me and if proven robust in the long term will be the death nell for the old relay.

Just like for the original relay, one still should have a spare in the glove box with spare fuses.

Wow! Talk about costumer service! I email the sales department yesterday because I ordered the wrong relay and Joe Baumbach got back to me this Sunday morning as to what to do. If this relay works as well as Joe I will never have a relay problem again. Thank you Joe!
And by the way I have zero ties with this company or anyone who works for it.

Looks like a great idea but I do have a suggestion for added reliability. (Better never then late ehhh?!)
The biggest vibration and shock loading in a car is vertical because of transmitted road vibration. Having the board horizontal will make it bend/flex more from these vibrations (even though it is quite reduced because of the drastic reduction in weight from the lightness of the chips.).
The unit would be better protected from vibration if the circuit board was turned up on edge.
(As a side note: The DME is more resistant to vibration if it is mounted on edge too. Not easy to do in a 911 but in a racecar it could be done.)

What is the difference between the pump-prime and the regular one? (I have an 86 911) Not sure if one is an option or something that is required for a particular model.

With a pump prime option, the fuel pump will run its sequence before cranking the engine. This *should* result in a faster start.

FTech has done the basic DME work for a 4 cyl as the 944 DMEs has been available for quite a while. The 911 is a much larger market and provides a real opportunity. I'd really like to see the DME+ board applied to the 911. There are a lot of data acquisition products that work with an OBDII connection and I think that would sell well.
