Did you come here to ask for some informations or to teach us how to tune?
Reading your posts it sounds like you're just encouraging the use of the microtech without really asking for some help.

Now again, since your poor customer could turn out to be an unfortunate victim of some thread mayhem: what do you need? Provided that the microtech is a pretty primitive ecu, how wold you like to reach your goals?
This could help giving plain answers.

Hey no problem, I was going to make a comment in that thread but it would have been in the same context as yours...not fully thought through and out of disappointment/anger or whatever you call it.

All good

No it is a local.

Zeon if anyone is curious, really never posted much but yeah really shitty situation for what happened. But things like that happen I guess.

 

The premise of this thread was loaded with irony and destined to the current conclusion.

 

Yes, persistant ignorance is something hard to fight. I guess that keeping a standpoint in tuning would be like keeping one in medicine... technology does change and calling something like the stock ecu "not advanced" looks much like talking about the 8bit rx7 ecus.

 

I'm not encouraging anyone to use the Microtech ECU's. It was merely suggested that reflashing the stock ECU is the BEST tuning method when in actuality it really isn't as that highly depends on application. Still running an N/A RX-8, sure reflashing would probably be the best way to go about it. Add turbo and looking for a high performance, it no longer becomes the best method.

Yes, the Microtech is probably one of the most simple standalones out there but it is preferred by many tuners out there. It is especially often used in 20b applications.

Anyway, I already got what I needed out of this thread on the first page. Everything after has just been completely off-topic and full of biased opinions. Would appreciate if the bickering stopped as well.

Hence my observation of the irony in the first post.

 

And that would be you.

I really hope that you aren't suggesting that a 16x16 or even 32x32 fuel table referenced to MAP is "higher resolution" than a fuel table for each gear, overlayed by a Ve table for the motor, overlayed by an absolute throttle position table, overlayed by tables for IAT, ECT and BARO, overlayed by an RPM delta table, all referenced to absolute air mass.

 

Key word being "overlayed".
MM, I am ready to go back to a Tascam 488 MkII. Are you?

 

I am no longer responding to this thread unless its something about oil metering.

edit: I realized I'm getting caught up in your bickering, so only going to care about direct technical information.

I understand your point but i have to disagree.
Add a turbo with a properly mounted MAF and the stock ecu can handle it. For sure you can't scale the MAF up to infinite but up to today there's probably no system topping over the MAF's capabilites.
I think that the first Standalone comparable to our stock ecu is the motec m600 with some add-ons. It would be a fair battle between the two imho.

The problem is that the discussion got trapped in "general" for this car while you were probably referring to your kit (esmeril), already well known for not being that much maf friendly because of the maf's location!
Saying that the accessport or any other stock ecu flasher is junk just because in your configuration is not optimal is not fair.
Said that, i will use an accessport to tune my car with a pretty good turbo as well and believe me i've done my homework!

Here, searching a bit, you can find some screenshot of the Hymee's protuner. That could give you a base idea of what the stock ecu can handle.

 

You're only talking to yourself now, bse50.

 

Yep, guess so. He replied while i was still writing

Angry with me Charles?

 

OK then -
The OMP is a stepper motor. It is not voltage controlled.
Your Microtech does not have the ability to control it.
Then again, neither does the Haltech or Motech because their stepper outs can't deliver the PW that the Mikuni requires.

 

Thank you. So the only solution to modify this is with the accessport then or to premix.

thewird

 

Or build a stepper motor controller.
Of course, the PCM will freak and attempt a limp mode, but if you are using an external computer for fuel and spark, that won't matter.

 

That would be a neat thing to try if this was my car but since it belongs to someone that I might never see again after I'm done with it I have to keep tweaks with what should be reliable instead of experimenting. Too bad the Microtech doesn't have this programmed in as it would be useful.

I predict you will see them again next time the weather turns LOL

 

I'd hope for a different reason then your suggesting though.

I'm fairly confident that the Microtech can control the temperature changes correctly as the AIT sensor seems to respond pretty well to temperature change. I've been taking it home so have experienced both hot and cold weather as well as a really humid day we had today. A computer will only perform as good as what you tell it to do. Anyway, we will see, the car should be done this week.

Well if you succeed my hat goes off to you ...

 

If you shoot for the middle (running crappy everywhere), it won't be as big of a deal. lol

 

What do you mean?

thewird

 

Just stupid rich everywhere. Especially in cruise, idle and transition.

Essentially, if you set the idle to anything leaner than 12.7:1, it won't idle once the baro, ambient temp or humidity changes.
The IAT table doesn't have nearly the granularity to be useful and the fixed data points are too far apart.
Same goes for ECT.

 

Sigh...

thewird

 

Let's put it this way; if you are able to get the Microtech to work with the RX-8 in a fashion other than what MazdaManiac describes either you are a WAY better tuner than he and Scott Glassburn or Mazsport fucked up the Microtech when they modified it and sold it as the "Interceptor-X".

That's how it has been for years around here and if you can do better than you will have a LOT of customers coming your way for new Microtech/Int-X tunes and the rest of us shall applaud and support you.

 

Well that puts it better, we will see then.
