Xede is by far better

You can tune for best ignition timing so you can avoid knock at all costs. The Xedes map offers better resolution than even the stock ecu can provide. All with free software to do this with.

What more can you ask for? Oh wait, maybe some viewable knock =P

 

But I thought the FLASH IS MUCH MUCH cheaper compare to XEDE so of course you go with the best bang for buck.
Its like Intel and AMD we all know Intel is more EXPENSIVE but AMD is cheaper and FASTER !! Bottom line I think if you want to save Dynoflash, you got too much money no where to spent XEDE all the way.

 

These arent Ozs if you want to go cheap penny pincher with your 32K premeir sportscar on THE most important thing oh well see you in the service bay

 

I did the Dynoflash through the mail. Feel it was well worth it for $225. I don't have access to a tuner and a AWD dyno, so this was the best bet for me. Xede may give you nice gains, but no one in my city can tune it as far as I know. Plus I did not want a piggyback and have to remove it to go into service. Dynoflash is stealth and nothing to hide when I bring it in.

 

True Dynoflash would be good for people who:
Just want a few easy HP
Do not have anyone to tune their fuel/ignition maps
Do not have access to a wideband o2 sensor or the like
Don't want to spend too much $$

Xede would be optimal for someone who:
Wants the best for their car
Is able to tune their fuel ignition maps (although Shiv's base maps are very, VERY good)
Wants to extract the most potential safely mod after mod

Oh and btw - most dealers dont give a **** about your piggy back's, at least the ones here in Washington dont. I talk with them about my tuning and the techs even give me pointers! =P

 

I dont understand why you guys just cant accept the fact that is cheaper and performs decent. You make it sound like this is some EBAY 20 dollar performance chip upgrade, why try to do this man ? Come on be real guys we know xede is great but compare the result and price Dynoflash is much better.

 

Decent isnt good enough

 

It certainly has a point. I am just trying to get someones question answered and have some meaningful dialogue. You have answered the question so just move along .

 

what kind of poll is this, oh wait there is no poll. I was going to get my vote on and ther was no voteing to be done. I would imagine there are more dynoflash's on the site than xede's do to availablity.

XEDE IS DA BOMB

 

your dealer must be an exception, but my dealer would give me a hard time and i believe most would, especially when it comes to messing with A/F and boost. Any dealer WOULD void your warantee if you have an engine failure and they see the Xede tapped into your ECU harness.

 

Seriously - and with all due reverence and respect . . . . do you even understand the concept of a piggy back vs. a reflash and how each works???

Let me give you a quick basic ecu 101 update so you will not be silly enough to ever say that the Exede has more "resolution" than the stock ecu!!!

The exede is basically a piggy back devise - much like the unichip that Shiv used to hawk and or the SAFC or Emanage

What they all do is basically the same concept - the INTECEPT the sensor signals comming into the stock ecu and either increase or deminish them - delay or advance them - in that manner you can adjust the stock ecu by tricking the ecu into thinking - for example there is less load on the engine because there is less MAF signal thereby reducing the fuel and running leaner - - OR - - delay the crank trigger signal and trick the ecu into changing the ignition timing

You can NOT have ANY greater resolution than the stock ECU has becuase the stock ecu is still firing the coils and turning on and off the injectors

There is no enhancement in control over what is already there

Its like putting a super fast modem at the end of a phone line - you can only download stuff as fast as it goed through the phone line

Piggy backs like the Exede are actually very poor ways to tune a motor becuase you can not write directly to the base map - ALL you can do is trick the sensor signals. When you change one sensor signal it effects the other parameters. It is really a band aid approach to tunning a car which is only viable when you are on a budget and / or when a re-flash of the stock ecu is not available

Ther are other drawbacks to piggy backing your tune

Many of the piggy backs are TPS based - meaning they reference off your gas pedal as the load - which works Ok when you are under full pedal down operation - what if you are on part throttle - full boost ?? Guess what - your piggy back that is TPS referenced can not deal with that situation

In fact the piggy backs sucked so badly that in the old days Vishnu had to come out with some new box - forget the name - just to deal with these kind of issues

Next - we have the issue of changing your boost level with a EBC or MBC - since most piggy backs are not LOAD based - they ONLY are dialed in properly at ONE set point. Regardless of what resolution they have when the load cell changes to the next row in the stock ecu your tune is changing period. You still get what ever percentage correction the piggy back has BUT you get the additional fuel of timing of the factory tunes next level.

Also - the piggy backs are less desireable due to the simple fact they must IMMEDIATELY process numerous signals and calaculate all corrections and send out new signals to the ECU - and all of this has to happen at the SPEED OF LIGHT - OR you get a very unique and strange feeeling tune I call the "piggy back lump" - this occurs as the piggy back tiny $25.00 "brain" attempts to perfrom hundreds of calculations with in a split second as you are racing through your power band - - I don't care what the piggy back hawkers tell you - THERE is a delay and its substantial

Also - I have logged numerous piggy back inputs and out puts and they ALL create errors in calculation and mistakes - - who exactly is checking up on your cheap piggy back to see if it is cutting exactly 10% of the MAF signal as you are running 100 mph down the highway - - sometimes its 10% - someotimes its 9% and sometimes its 14% - it jumps around like a mexica hat trick - thats why I cal it the "PIGGY BACK LUMP" when I drive one

Ok enough about piggy backs - what are the disadvantages of re-flashes - #1 - you can't adjust it yourself - end of story

In every other catagory - aside from end user adjustability - the re flash is superior to a piggy back in every manner

remember - when we reflash your ecu we have direct ability to re-write the entire base fuel map and also re-write the base ign timing map - once they are flashed in they are set - there is no errors of calculation - no delay no cross effects - you get what it in the active cells - period

The ONLY real limitation of the factory ecu is the actual MAF sensor itself - a MAP based tuning method such as a total stand alone is the superior choice for very HIGH HP applications

For anyone under 450 whp - a reflash is the best and most effective way to proceed AT ANY COST

It make me laugh to see these guys posting that the reflash is a "economy" or "cheap" tuning method - thats a real laugh - the only thing cheap is the price tag becuase you dont have to buy any hardwear

 

Als right but it is no way comparable to a ****ty unichip. Nothing wrong with using this form of EM its just a tool

 

I am not donw with my essay - keep checking back - I am going to post up some good data - my fingers are fresh

 

When you change one sensor signal it effects the other parameters.

This is out of context. the changes are accounted for and are directly proportional to the changes you just induced- like I said nothing wrong with that
In fact the piggy backs sucked so badly that in the old days Vishnu had to come out with some new box - forget the name - just to deal with these kind of issues

Called the EMI- once again out of context this was to smooth the wrxs unique and inherant CL-OL transition nothing to do with shivs prefered tuning- the unichips crappy 12 load points were all we had till shiv himself scheemed up the Xede
Next - we have the issue of changing your boost level with a EBC or MBC - since most piggy backs are not LOAD based - they ONLY are dialed in properly at ONE set point. Regardless of what resolution they have when the load cell changes to the next row in the stock ecu your tune is changing period. You still get what ever percentage correction the piggy back has BUT you get the additional fuel of timing of the factory tunes next level

Does not apply to the Xede it fires the factory boost solenoid itself- Like them apples?

sometimes its 10% - someotimes its 9% and sometimes its 14% - it jumps around like a mexica hat trick

this is an accurately working intercept computer adjusting for real world load conditions- monitor the factory ECU and it is making the same voltage #s based on the load. Cheap processors are one thing high quality expensive units are another (read Xede). Logic would say there is MINUTE delay I have never seen it scientifically lagging behind in high quality units. I have on cheap *** units and even a microscopic delay will throw a CEL

 

Its much more efficient and accurate to adjust the fuel map - - and JUST have the fuel map change. With a piggy back you are also altering timing - which then has to be re-changed and which of course then effects fuel

Obviously If you are able to write directly to the base maps and just change the fuel with no change in timing - as in a reflash - you can be much more accurate
