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 ****.

Its a good argument, in the end thats all that matters. The rest is sugar coating.

i autotuned the hydra for years.


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.

I am looking forward to hearing this success story. It's pretty much the only thing that I'm waiting on to dump my Hydra and make the switch myself.

Getting my new MAP sensor from Travis sometime next week. So far it starts and idles. Drove on the stock injectors. No complaints so far about the adaptronic, even though I've been having MAP sensor issues from day one, which has NOTHING to do with it.

Wait till auto-tune screws up and air-france's your engine, I would never trust a computer to think for me.

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.

I didnt know the LC1 sends a error back through its serial cable that something is wrong. All I know is that it will just produce the same reading based on how you set it up.

you can set the sensitivity of the autotuning algorithm based on RPM and MAP stability and if it is not held steady in both for a specific amount of time, it wont tune the cell.

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.

Just to be clear when I mentioned traction control I wasn't talking about launch control. The Adaptronic has input for two speed sensors so it can do real traction control and you can adjust the slip angle on the fly. Handy when it rains 300 days a year.

One of the reasons I went MS back in 06 - is the serial protocol for this ECU open?

I think they use Modbus.

but that may be only for extracting data and, unfortunately, disabled in beta firmware/software.

Just to be clear, when I mentioned traction control I meant learn how to drive.

Code:
Feature                    Adaptronic         MS-I           MS-II
Injector resolution           0.7Ás          100Ás          .67Ás
Ignition resolution            0.2░           0.3░           0.1░
Processor                     16-bit          8-bit          16-bit
Speed                         200Hz           8MHz           24MHz
The adaptronic destroys the MS-I for injector resolution (about 100 times faster), however the MS-II beats it slightly in both categories....

I would like to believe that the Adaptronic does not have a processor speed of 200Hz, yes?

that's what it rates its "main loop speed"
