Tools Needed:

10mm wrench
Wire cutters
Crimp tool
mini torch or soldering iron (only for the heat shrinking.)

What comes with the XEDE:
XEDE unit
Wiring harness
7 Male spade connectors
7 Female spade connectors
3 Scotch locks (taps)
Wiring diagram/instructions

I didnt take a picture before I started because I was too excited. (Can you blame me?)

Here is what it should look like (almost) before you start.

First, remove the harness cover seen here.

http://i6.photobucket.com/albums/y241/Deathwater/mazda/002.jpg
Then remove the battery cover.
Disconnect the Negative (-) side and tape it out of the way. I am extra careful because I hate electricity and actually covered the terminal with tape.
http://i6.photobucket.com/albums/y241/Deathwater/mazda/003.jpg

It looks very scary at first but do NOT be intimidated. There are 8 wires coming from the XEDE unit. Our speed 3 only uses 7 of them.

http://i6.photobucket.com/albums/y241/Deathwater/mazda/004.jpg

Following the diagram supplied by BEGi, locate the wires on the harnesses. Only one wire from the Right side harness is used. The other 6 or on the left harness.

You have to keep in mind that this unit is an INTERCEPTOR style. It goes in between the sensors and the ECU. Once you can understand that, the install is a breeze. Took me about 20-30 minutes in the rain.

once you have all your wires crimped, use a soldering iron or mini torch (be careful not to hit the other wires) and hit the heat shrinking to insulate your crimps.

All the spade connectors (male and female) and the three wire taps are all supplied by BEGi as well as a bunch of zipties.

Then, plug in the harnesses to the XEDE unit, black to black, gray to gray.
start zip tying and decide where you want to stash away your XEDE unit.

I was just barely able to put back on the covers on both. If I had taken a little more time, I could have done a better job and chose to cut the wires further down.

If you take a look at the pictures, it looks almost stock. You wouldn't be able to tell unless you knew what you were looking for.

Now, to take on some unsuspecting STI's....

Little do they know, an extra 57 whp and 70 ft lbs or torque are waiting for them.

Hey thanks for the write up dude. (first) I can't wait for you to post on how it DRIVES!!!! Are you using the stock maps or going to do some custom tuning?
Looking forward to your write up on the test drive!!!!!!:)

I'm saving $$$ for one of these babys, but I'm waitin for plug-n-play.

I've been driving it all day now.
Its amazing. I can floor it in second and it pulls me off the road. Well, the roads are wet so I couldnt really open it up till just a little while ago. 3rd and 4rth pull REALLY hard now and it does NOT let up. You know how ( I posted a video also) the boost only spikes to 16 then settles on like 10-13? now it holds the boost at 15-16psi all the way up. Im sure there is ALOT more but like I said, it was raining almost the entire day and I couldnt open her up fully.

I am trying to schedule the dyno for next week. The way the wiring is set up, I can just unhook the XEDE and plug the wires back together so im back to stock.

The dynos will be as follows.

Totally stock
XEDE
TMIC no XEDE
TMIC & XEDE.

I will be getting a laptop to borrow tonight and custom tuning it just a little bit to compensate for the TMIC.

Intake is here also. Going to install it tomorrow though. :)

Stay tuned...

300whp is just a tiny step away if not already here. :)

ok.. roads dried up a bit.

From about 15 mph in 2nd, I punch it.. wheel spin.. shift third.. catch traction for a little while, hit redline, I get wheelspin again.

I found ONE thing wrong with the XEDE.

I have no idea why I typed boost cut. I have a speed 6 so I don't have that silly boost limiter in my first few gears.

I'm trying to find out about the fuel cut. I already have full control of my boost with an EBC... but fuel cut hits sometimes at mid RPM with just an extra psi over stock. It's really bad in the cold weather.

People who have added downpipes are hitting it all the damn time and 4DRHTRD is really suffering with the upgraded turbo. He's supposed to get this system installed Monday so I guess we'll see if it does indeed solve the problem.

But seriously... how about boost cut?

How about now?

BEGi reported that they saw a 3mpg increase.

I have been flooring it everywhere because the feel of the car slamming you into your seat is highly addicting. Obviously I wont be seeing that same increase.

I'll try to drive it a little more civil and see if I do get better mileage.

how reliable can the xede run.....in a long run....50k, 80k later....will the xede cause any negative to the engine? i heard people say the tranny/clutch will hold all the extra whp.....but how about the DSC?? can the DSC takes all the punishment??
lastly ken do u have anybody can do the install/tunning in ca bay area?
thanx guys

frankly any kind of mod you do to the engine could in some way potentially damage the engine. the only way to guarantee that a modification won't harm the car or void a warranty 100% is like abstinence and pregnancy :) just don't do it. everything is engineered and designed to work within certain parameters, however its also true that the car is tuned to run very conservatively from mazda. this is to account for a variety of climate conditions, altitudes, driving styles, etc. the old phrase "jack of trades and master of none" in a sense applies to how cars are tuned from the factory.

that said, as long as your air/fuel ratios are right and your driving habits are not steve mcqueen at every red light, your car and engine will hold up fine. BEGi has always been very big on streetable and reliable power in thier work. the fact that the engine is direct injection allows for a bit more leeway than your tradition fuel injection systems - its less easy to detonate and much more precise in fuel delivery.

you make some good points, I didn't know that mazda could tell that your ecu was flashed. Can they still tell if you unplug the battery after you flash it back? I really hope that they make the xede plug and play.

of course they can tell :) this is how they flash cars to begin with. you go in for warranty work, they scan the car to see what version you have on your ECU, the system will tell them whether or not the car needs an update. many people have gone in with thier msps when bought second hand to find out whether or not they had gotten the dreaded flash ;) factory computers have become very advanced, almost to the point of black boxes where they log a certain amount of information about things like recent driving habits. you could go in with a blown engine and if the tech analizes sensor data from the system memory and sees what he feels is evidence of vehicle abuse, they could state so and lead to your warranty being voided.

as for unplugging and re-plugging in the battery, thats not going to stop a mazda scan box from seeing what version of what software is written to the ECU last and by what kind of device. the file will still be there and the fact that it was flashed by something will also be there. if it doesn't correspond to warranty work done on your car then they might find that suspect. this is also a reason why you can't just clear a CEL and go in for an emissions test and pass this way. basic OBD2 scanners at emissions stations can see that you've tried to clear the memory on the ECU recently and that there isn't enough logged sensor data to pass the car.

i think when other systems become available the choice will come down what features and goals the consumer is looking for and willing to pay for. personal preference will play a large role. as for being plug and play, latest word is that the harnesses are familiar to a company we've contacted and that we may be able to import them from japan. i'm not guaranteeing at this point that this will be possible, so please don't take false hope in that.

Does it control the Throttle by Wire, i.e., change the mapping so it stays open longer or acts like a wired throttle instead of closing to reduce torque?

Are you referring to open loop vs. closed loop? Throttle Position Sensor?

the newer mazdas use an electronic throttle, not the tradition cable actuated throttle. i think what he is asking is if the XEDE can assume control of that system to make it act more like a conventional throttle.

Yes, that's my question.

According to somebody's log the throttle closes by redline, limiting top end power; it also closes at the onset of boost around 2600-3200 rpm, I guess to keep torque controlled when the turbo first kicks in. I'd like to see how the torque/power change if the throttle was kept open all the way to redline.

you mentioned some dyno's with different mod configurations, did you post them?

the cai you mentioned that you had, is that the xcel or is there another out there for us real soon?

i just ordered the tmic, and am wondering what to expect with the cai too.
i may buy the xede but only when plug and play.

please show us the numbers, i plan to time 60-100mph in different gears with my mods as i install them to monitor gains and share info with others.

cheers

No, as I said in that same post, the dyno will be sometime next week.

I never said I had a CAI. I said I had a short ram

i just ordered the tmic, and am wondering what to expect with the cai too.
i may buy the xede but only when plug and play.

I have seen only one dyno graph for the speed 3 with a CP-E CAI. It gained around 15-20 whp.. which is hardly believable. At most I would think a 5 whp gain.

please show us the numbers, i plan to time 60-100mph in different gears with my mods as i install them to monitor gains and share info with others.

cheers

What numbers? If you can afford to dyno your car after every mod you buy, please do post the graphs. The community needs more numbers to verify just how awesome this car is.

sorry for taking an interest.

I am trying to schedule the dyno for next week. The way the wiring is set up, I can just unhook the XEDE and plug the wires back together so im back to stock.

The dynos will be as follows.

Totally stock

I said trying. Dyno WAS set for the 22nd but I found out I have to work that day.. have to wait till tomorrow to find out my schedule for next week.. then I will schedule it for whatever my day off next week will be.

BUT.. drags are on the 20th.. so I will at least get some good 1/4 times.

01-20-2007, 05:53 PM

Power is gone by 6k rpm because of the ECU controlling the drive by wire "80% limit I think". Rev limiter is 6800 or so I dont think there would be any need to increase it with the factory turbo. Aftermarket turbo and a ability to control DBW would be a diffrent story.
Do we know if its the DBW that controlls the redline or the ECU/PCM that kills spark/fuel??? I have dealt with the DBW systems in the past and we have a fix for it if its just the DBW that kills the power..

Terribly sorry for the bump, didn't see anyplace else for this.

So, if I hook up the Xede system, do I just leave it as it is in the engine bay and just forget about it(besides hooking it up with the laptop to tune the engine)?

Nutari, any updates on the Xede? Been a while, ya know....

yes, hook it up and go. For OPTIMAL results, dyno tuning is recommended.

What more updates do you need? Car is running fine. I cut everything apart and hardwired it in there. (Solder with shrink tubing) looks totally stock now cept for the XEDE unit. I am going to put in the map bank switch either tonight or next day off. Also going to wire in some LED lighting for the footwells because I like pretty blue lights.

I am so glad you posted those dyno graphs.
I have been trying to figure out which direction to go next w/ my speed3.

My first 2 upgrades were the COBB SRI and Forge BPV.

I have gone back and forth w/ what upgrade to do next.
It came down to the ETS TMIC after seeing the results of COBB'S AP initial release.
I waited for the release of the COBB AP but I am really happy with the results I am seeing w/ XEDE.

XEDE will be the direction I will be taking now.
