I have experience. I have done a 20-valve 4A, a 3S-GTE and a BMW motorcycle (alpha-N).

There are, of course, hidden costs. If you want to run sequential injection, you need their latest box, and you need to build a signal conditioner. I have yet to see a stock trigger work with them, even with all of this.

If you want real-life IAT compensation, forget it.

Their Accel enrichment is a bit of a joke.

It is open-sourced, but don't let that fool you. You will be SERIOUSLY hardware-limited! If you are a half-way decent coder, you need to be REALLY good at REALLY tight main loops. This even applies to their newer boxes.

You build it (unless you use a service that does it for you). Either way, you have a hand-made piece of electronics, which is never as reliable as manufacturer-built.

Basically, you get what you pay for.
