Not exactly true. I've used several Xede's and I've always been able to work off of shared maps through the course of typical boltons. This allows you to grow your ems with your incremental additions while not having to ship off your ECU. You can also remove it in a few minutes for dealer visits. I believe the flashes are detectable. Also, launch control is available on the Xede, although fuel cut and rev limit are not accessible. With an Xede you have the option of self tuning but can rely on available maps and biult in safety features to protect you. This applies in varying degrees to other piggybacks so make sure you search on the topic and form your own conclusions.

Congrats on the RS

 

Relying on "available maps" when purchasing an expensive piggyback is not smart. It's just like using a mail-in flash. If you get one without doing your own tuning, it's a poor decision, imo. Less features and very expensive. A piggyback's purpose is for self-tuning. Those who get it without doing their own tuning just spent too much money.

 

The reason I suggest the Xede is that it helps people avoid making costly mistakes and forces them to see the multidimensional elements of tuning. IMHO boost should not be adjusted in isolation of timing and fuel considerations. Give a guy a mbc and he's going to turn up the wick more than he should.

Another reason I suggest the Xede is that it may be the only mod needed on a IX. I'm willing to bet that once all the tuning parameters are hammered out it's going to be vicious I plan on going with a catless TB and Xede and maybe a cam(s) depending the results we see.

 

Not smart huh, I'm pretty sure more motors have been blown with mbc's than with Xede's. You are a vendor and have a relationship with Dynoflash, you want to peddle thier goods that's fine. I'm not a vendor, just a guy that loves evo's and is on his third one that will be equiped with a third Xede in various stages. I've never had any problems with maps for the various stages and I've put close to 100,000 hard miles on these setups.

As far as tuning, a piggyback let's you grow into it, and with an Xede you have a support system. The same could be said for UTEC, but that system is not as idiot proof regarding knock control.

 

Well you make a point about more motors blown with mbc then xede, but think about it $85 vs ~$1,000. More people are going to have the mbc then the xede.

 

I'm no vendor. I'm just a regular Joe who has accomplished a lot with very little. A Xede costs more than I've spent on my mods. That's why I don't see it as a good suggestion for most people.

Also, what do you think the ratio of MBC owners to Xede owners is? You can't make a statement about blowing engines while ignoring the drastic difference in numbers there. An MBC is only as dangerous as the user. If the Xede is made to be idiot-proof, then that's fine. A $200 idiot-proof flash does the job, too. I haven't seen any Xede-equipped cars match my times. Have you?

 

Regarding the numbers, please feel free to take a random sampling of Xede users and MBC uses and let me know the measure of association between each and blown motors. I was not attempting to employ fallatious logic comparing raw numbers...although anecdotal evidence is in my favor as well(unscientific as that is).

Regarding value, when you buy a flash you have nothing tangible, nothing you can adjust or grow with other than to send off your ECU for min. $100 a pop. This will add up fast for most here. And if you go stand alone in the future you have nothing to sell to offset the upgrade...all you have done is lined the flasher's pockets.

As far as what it costs you, you always place a premium on price...which is fine, that's why they have kmart. I think that a good piggyback system offers more long term value.


As far as matching your performance, you would need to flash to do that (to adjust the fuel cut/rev limit). However now you have voided your warranty due to the ability to detect a flash. If that's not important than it's no big deal.
