Why is Adaptronic better than Megasquirt?

The only thing you said was [paraphrasing]it doesn't matter what ECU you use as long as you can get a good AFR.[/paraphrasing] But it was a poor argument at best.
it really goes beyond features, the code is better, the processor is better, it's more robust, it's simply a better ECU. Do they both work? yes. Any reason to crap on it? not really. Am I going to sell my MS for one? no. you're arguing about trivial ****.

As for auto tuning, it shouldnt need to constantly tune. You tune once and you are done. If the ECU is constantly re-tuning that means something is wrong with your car that the AFR's are fluctuating. Nice feature to have, but beyond the initial and final tune, its pretty worthless. Its a nice to have, not a need to have.
see there's this thing about 3D maps. you're not in every cell just by driving the car once. and then you raise the boost. and then you change injectors.
that's why OEMs make their **** adaptive too.
oh and the adaptronic has a function that sets tuned cells to "tuned" and locks them in after it feels they're within the proper tolerance. they turn green
anyway I been driving my car for several days and the whole map is not green.

A computer can only be trusted to perform a repeating task over and over and taking into account reliable data, when your o2 sensor fails it better be smart enough to know. Does the adapatronic stop tuning when it detects that engine load and AFR dont make sense? What about when the knock sensor fails and it keeps advancing your spark?
If it is smart enough to know, I stand corrected.

If you use the serial port the adaptronic will stop tuning and switch to open loop if the sensor fails. I also have an LC-1 with a light put in to flash when its running incorrectly as well for backup.
As far as spark tuning the adaptive functions do have a programable maximum in, but knocksensors usaully don't fail. You have to have some common sense when using any piece of hardware. When you tune spark it would be good to understand what deto sounds like. If your car suddenly drops in power and begins surging your next instinct should not be to hammer down and "blow the carbon" out of it. It also only increases timing if it senses more torque is available by doing so. It is unlikely it would go all the way to the user set limit.

assuming load/afr values dont make sense means you're pretty fucked even without autotune doesn't it? I think that's irrelevant. ie if your 100% mechanically controlled injection loses a vac line and thinks you're at 100kPa when you're at 300kPa, does it matter if you can autotune or not?
the system is way more flexible than at least the Hydra in that regard. the hydra will go happily on autotuning when your car is at a CLT of 0C and screw up all your cells (think fighting a coolant enrichment of 20%). at least the Adaptronic has a temp window.
but lets keep this in perspective. no engine management can do it all on its own if you're a retard. suggesting that because the adaptronic doesn't have a sixth sense it's a POS is a little extreme.
pretty sure the megasquirt doesn't have the features you want either.

^ Nah, im not suggesting sixth sense, but everything you have mentioned so far I do not disagree with. If it does everything you say then that's freaking sweet, and I stand corrected.
As for the MS's features, I have no need for anything else beyond EBC which works, and launch control which I use as a valet switch.

Handy when it rains 300 days a year.
