Good People of Vishnu

What do you guys think will be the effects of running just an Xede (stage subzero) on a stock Evo at 10k, 25k, and 50k miles? Naturally one would expect the usual wear items to go faster with a more agressive tuning, but I'm more concerned with things like sensors.

I could give examples, but really I'm not trying to compare to any other car or vendor. I'm just wondering what 'gotchas' you guys see?

ps- I find it strange that nobody has asked this question before, but i certainly didn't see it in a search.

 

Once you have the XEDE you will want more. Power is addicting.

 

Agreed. No sensors are harmed with installation of the Xede

 

Not true, the proprioceptive sensor gets damaged...

 

The Xede has its fans and its detractors, many of whom are very vocal. The fact that there have been no threads where users complain about sensor damge casued buy the Xede makes a good statement. It probably does challenge self control though and therefore may indirectly harm you bank account.

 

I'd be curious as to what the 'detractors' have to say...as well as the extent of their experience from which said comments are based.

As far as I can tell based upon my understanding of the Xede, there should be no long term 'side effects' from running it. If anything, a dyno tuned Xede should *improve* the WOT reliability of your modified car for the long term.

- The factory sensors, computer, and OBDII monitoring systems remain intact.

- The factory part throttle settings remain relatively unaltered, which ensures reliability, longevity, and fuel economy.

- The system retains the MAS, which allows the computer to continually, accurately adjust itself over the long term - thus providing optimum longevity and reliability.

- A MAS based system will adjust itself accordingly if you make moderate changes - can't do that very well with a MAP based stand-alone.

This seems like the way to go for a daily driven car, especially at roughly half the cost of an alternate option.

 

I tend to agree

 

I have a custom tuned 1+. Effects so far:

#1. Kick-me-in-the-*** power (also kicks the collective asses of most of the cars out on the road)

#2. Improved fuel economy

#3. The only downside, I can't go swimming anymore

 

I have a stage 1+ car and for the most part it drives as smooth as stock. Obviously there's a LOT more power there over stock and it is delivered in a very smooth powerband. As far as longevity goes, I'd say a lot of that depends on how heavily modified your Evo is. IMO, the XEDE is one of the most elegant tuning solutions for all of the above-mentioned reasons. However, tuning your car more aggressively (even with Shiv's conservative approach) does seem to make the ECU more prone to throwing various CELs ... the infamous P0330 being among them. For example, I am currently getting an intermittent CEL that only seems to happen when I'm cruising along at something like 45mph. I don't know what it is yet, because it always clears itself before I have a chance to have my dealer look at it, though.

As far as outright wear and tear on the engine and other components ... I don't think the XEDE is any better or worse than other tuning solutions. IMO wear and tear has a lot to do with driving style and maintenance habits. The only kudos I would give to the XEDE in this regard is that it is fairly foolproof once you have it installed correctly just as long as you don't start manually editing the maps ... at that point all bets are off

I'm on my second Evo and second Xede and I haven't noticed any problems. The best part is that you have a variety of boiler plate modification paths to follow from just the chip torque through a turbo upgrade.

 

I remember reading something by a guy named Corky Ball in his book Maximum Boost.

He said something like: an increase in power on an engine's internals of 100 percent only equals a 20% increase in stress on an engines internals and since most engines a over engineered, increasing the power is fine, provided one avoids heat and detonation.

Vishnu, and most tuners here, go to great lengths to avoid detonation and heat which can damage certain sensors, but more likely engine internals first (and most likely more catastrophic) than a sensor.

With more horsepower you'll encounter more driveline stress and you could expect clutch, differential, drivetrain mounts etc.. to wear quicker along with brakes, tires and more frequent oil changes.

 

Long term effects primarily revolve around the use of nanoprobes. When you drive the car with the new Xede unit, these probes are released from the Xede when you hear that clicking sound. Eventually you become a mindless drone that spends all your money at Vishnu and become estranged from your non-assimilated family members. Version 3 of the Xede firmware will actually be filled with new invasion and assimilation plans.

 

Correct and good info to err on conservative I like to say the doubling of BHP roughly equates to an increase ~33% on the rotating assembly. This is of course provided your tuner avoids Det. If the tune is too aggressive all bets are off and the % goes up massively

 

Are you using 33% because of the raised rev limiter?
