Agreed on the "anything else"

I cannot name any ECU on the market today which springs to mind which I would not prefer to have than an emerald.

They work, but so doesnt everything else, and everything else does, and everything else does so without mapping software that is so horrible for road mapping.

And even for mapping on the rollers, where it works better, its still just not a nice product, just feels really ameteur to use.

Comparing it to an autronic for example, is like comparing a kia to a bmw, sure the kia works, but its just not a quality product.
