Vishnu XEDE progress

Wow... i cant belive it actually worked! Have you checked to make sure the nasty stock ECU isnt messing up your tune now that you've been driving it? When we did the emanage, it tok the tune for like 3 iginition cycles, and then started making its own changes...

Thats what I'm worried about as well... so we'll be checking for that =T
 
he other problem that you will never be able to get around with Xede is that with the stock maps as a base, they will shift based on conditions and your Xede tune will get pushed out of where it is supposed to be. It'll be a nice tune, but it will fluctuate over time and with different conditions. You'll never be able to nail it down to stay stable. A lot of people think it stays perfect, but they don't run constant logging or AFR's or so forth, if you actually track that you will see all the variations that occur over time. It most becomes a problem when you run a series of hard runs in a row and you'll see variation between each of the runs.

Did you guys get it to be plug and play?
 
=T I've still yet to get Shiv to send me the dyno graph results =P But I've been driving with the XEDE in for the past month. I know everyone is more anxious to see the dyno graph comparisons, so I've been bugging the hell out of Shiv everyday. If anyone is really interested, and live close to the Bay Area, you can give them a call to show your interest. Otherwise.. just wait ~_^

This has always been an issue with any tuning device granted it be a piggy-back or full standalone. Although when tuning witht he XEDE, the idea is to stay within the "happy zone" of the ECU so that the tune does not get "pushed out". One advantage to tuning witht he XEDE is that you can work in conjunction with the the stock map and keep all of the factory failsafes (ie knock threshold) that car manufacturers spend millions of $$$ on designing. (hint: standalones)

Although we have develped what we call the SMART system for the XEDE which can adapt to slight environmental variables (ie temp, altitude and octane). Thats not to say that a car tuned at sea level will be able to perform just as well at 2000 feet, but it does resolve the issues of having to be re-tuned every year (hint: standalones)

As for the variations between hard runs on the dyno, what we've observed were high water temps that affected performance drastically. This was already very apparent when running the car hard at track days for more than 15mins.

Couldn't source an affordable connector... so this will have to stay a wire-in.

- hint they spend the money more on emissions.. A system like the JandS safeguard runs circles around the stock knock systems. And if you are staying within the happy zones of the stock ECU you aren't going near the full potential of the tune of the car.

Ha!! That is the most BS thing I've ever heard. Unlike piggy systems like the Xede that lose their maps as the stock system re-calibrates once a standalone is tuned things are locked in for eternity.

Exactly... you can't do an accurate enough correction for the higher temps... one of the guys that runs the Microtech found that his 1/4 runs are now more consistent AND faster running the system compared to the stock ECU doing things.. and he is an NA car...

You guys will have emissions and generally a good tune, so it is a reasonably good system though for a lot of people. So it's good that it will be available.

How is this BS? We've been running this system on the EVOs flawlessly.

Well... the fact that he has an NA car dosent help in comparisons to the turbo charged cars. I'm pretty sure the main reason for high water temps is due to the addition the turbo and small radiator.

=) There is no solid comparison that would suggest that a standalone can bring out a cars full potential over the XEDE, especially at this point in tuning. We've had countless discussions on the EVO boards with different tuners that prefer using standalones, and it just becomes a big war.

This thread is dedicated to XEDE information, so if you'd like to leave a link to a Microtech thread, I'd be glad to read about it there =D

Well, you're just in time for the same thing here thanks to one of the other piggyback vendors ruffling everyones feathers all the time. You'll have to forgive Steve, I think he is still a little on edge thanks to the "other" guy.

Everyone knows that there are people who prefer a standalone and then there are others that like the piggyback. Debate the products and the advantages, but there is no need to be anything but civil about it.

My point was that having to re-tune a standalone every year was BS. I haven't researched how you guys have done on the Evo's to know really what has gone wrong or so forth... but that is also a considerably different ECU. Mazda's are known to be a lot rougher to deal with.. hell E-manage works without an issue on an Evo or Lancer yet is a pain in the ass on a Mazda.

Well if it's hot and your radiator and fan combination is not to the task you'll get high water temps.. my point was with the Microtech he was able to correct it and make the car more consistent and powerful at the higher temps... and you had said that the Xede hit a rough patch there.

Right.. it always becomes a big war... and it's a lot of misunderstanding and misinformation. I take issue with someone saying it is better or so forth than a standalone.. I don't think the standalone is necessarily different.. I believe that they both do the job, but do it in different ways with different drawbacks...

I realize this is an Xede thread.. and I didn't comment on standalones until you stated misinfomation regarding them... I corrected you and it's continued from there.

Yep.. I agree.. and I am probably a little extra "touchy" these days because of what you said..

I agree that it will work well and there are pros and cons to both... my issue becomes when people don't admit to the cons that they have with a system. NO system out there.. absolutely NONE is without flaw... so you better be ready to admit it so customers can choose which flaws they are fine with!
 
Nope =T
Sorry to get everyones hopes up...
If you're local and you really want one.. you can give us a visit to have one fitted on your car. Otherwise we wont be officially selling it.
The Xede that was installed on my car has been working flawlessly.

That's still pretty cool. (thumb)
