But then by the same token, we should just hide all configurations, and have an installation wizard instead of vemstune, like Microsoft. It asks you for the year, make and model of your car, loads the defaults and that's it. That way no one will ever configure their fuel injector output as the fuel pump and burn down their house, and damage the system's reputation as being a fire hazard.
I'm in software and I work for a major corporate wireless lan player. I cringe whenever I hear that we should make something easy to use. It's a half truth. A complicated product doesn't have to be easy to use. There are complicated things in life - if someone doesn't get it then that's just too bad. Now, making something more complicated than necessary is a different matter. It just needs to be as easy to use as possible - which might still be difficult or for some, even incomprehensible for some others. I'm no EFI expert, not by a long shot, but it seems the deadtime table is a pretty standard thing. We could just add a line in the help menu that says "If you don't know what this does, don't touch it".
I think it's more important to have a good explanation for the offered configuration (as Gints mentioned, many of the current F1 popups are either sparse, wrong or non-existent). But for this, I would be happy if there was any way to configure it, even if that means manually editing the config, as long as the firmware would know what to do.
For what it's worth, I'm impressed as all hell with how mature VEMSTune is as a product, for one as young as it is with such limited development resources (which isn't meant as a knock against the developers - they're just not a full-time army of managers, architects and developers, the way a corporate outfit would be).
