XEDE Engine Management System Available Soon!

[Anon Y Mous]

eh, probably not a "ton" of power but a noticeable amount I'm sure.

The boost limiter is my biggest complaint and the XEDE will more than handle it. The stock turbo is good for 20-23psi which should be a healthy bump over the stock 16psi. With my "more than adequate" TMIC from p-garage I'll be good to go with the stock turbo for a while.

That is kind of the route i want to go with my car. I want to some sort of ic upgrade, xede(only if it is nice and reliable with moderate hp gains) and maybe atp turbo upgrade sometime down the road.

 

[Anon Y Mous]

the XEDE is a very competent EMS. I'm sure you will be very happy going this route.

what I'm doing is buying the TMIC, 3" catless ATP DP and intake piping for now....the XEDE will control it and when I get bored with 23psi and bolt-ons then I'll just buy the $1600 turbo upgrade since I'll have the rest of the kit already.

So if I go with the xede and lets say further down the road i want that turbo kit that is avaliable all i have to do is reprogram the xede with some new software and away we go.

The software stays the same - Xmap. The maps in the Xede will change. This particular application has four maps, boost, MAF, Timing, and MAP sensor adjustments. If you add on a new part, you can tune it yourself. A wideband would be a handy tool, or any dyno tuner could do it. All you do is modify adjustments in the map to compensate, ie. add fuel, take out fuel, pull timing, reduce or increase boost. Once done save the map, upload it to the Xede and Burn it to the Xede. Then your done.

The next question is how do i do the download. do i have to do dyno tuning or is something i download from xede and put it into the xede and away we go again with having fun? Sorry for all the crazy questions, I just need some instructions on how this stuff works.

To download off of the Xede - F8 download and show maps. Then the latest maps burned to the Xede will come up on the screen. As long as the car is running, all changes you make are in 'real time' and become effective immediately. Once done save the map, upload it to the Xede and Burn it to the Xede.

You can visit the Xede website for a how to tuning guide. You could also download xmap software and play with it some.

Once again, cant agree more with you on that one. I wish my g/f was into cars!!!!

 

[Pololo_MS3]

So bottom line,

Since this is a step "forward" from a current piggyback, can you datalog different maps in real time ala FM Link ECU?

With the Miata, I used to do all my tuning in third and fourth gear making sure I went through all the zones in the Fuel and Ignition maps, then once I had my results, I will change them in the zones that either needed more timing, more fuel and/or other parameters such as your threashold boost and how knock sensor readings

BTW, every car is different so a "base map" is just that, a base map(very conservative) and I believe to get full advantage of this XEDE someone should "invest" in a dyno tuning ($85) provided they are able to measure AFR from the tailpipe and of course if you want to get very serious, a wideband O2 sensor is a MUST

Was the "guinea pig" tested with a Wideband O2 sensor or the tailpipe AFR from the dyno? What about the knock sensor? Since you were "just" tuning due to the richness of AFR, I believe the 1st and 2nd gear limiting factors are still there

This is indeed good news!

Keep up the good work

Sorry, no luck. I guess my 'image' would be probably be destroyed if I mentioned that I drive a F350 4WD? (shocked) j/k.. The Miata is the daily driver and the truck is for when the mood strikes. The Miata is turbo'd, alas the poor truck is not.

So bottom line, Since this is a step "forward" from a current piggyback, can you datalog different maps in real time ala FM Link ECU?

Yes, the Xede does data log and sends it to an excel file. Unfortunately, I have never tuned an Link so I do not know exactly what it data logs.

With the Miata, I used to do all my tuning in third and fourth gear making sure I went through all the zones in the Fuel and Ignition maps, then once I had my results, I will change them in the zones that either needed more timing, more fuel and/or other parameters such as your threashold boost and how knock sensor readings

It is the same principle for the MS3. However, tuning is done in 3rd, 4th and 5th gear since it is a 6 speed.

BTW, every car is different so a "base map" is just that, a base map(very conservative) and I believe to get full advantage of this XEDE someone should "invest" in a dyno tuning ($85) provided they are able to measure AFR from the tailpipe and of course if you want to get very serious, a wideband O2 sensor is a MUST

The base map is conservative at 288 rwhp (uncorrected). The wideband is always a good idea, but not needed.

Was the "guinea pig" tested with a Wideband O2 sensor or the tailpipe AFR from the dyno? What about the knock sensor? Since you were "just" tuning due to the richness of AFR, I believe the 1st and 2nd gear limiting factors are still there

The car was tested logging from the stock wideband sensor and also AFR from the tailpipe while on the dyno. Knock is listen for via microphone, and while street testing. Tuning is also done at certain boost levels too. The wastegate solenoid is controlled electronically based on rpm and load value. I still need to check on first and second gear, the car comes back for more mods in a week or so.

This is indeed good news!
Keep up the good work

Thank you! I hope everyone had a good holiday season. Happy New Year!

That must take a lot of experience. Still, it makes me wonder about the long term effects of increasing allowed knock as a way of making more power. But if you want to play, you're probably gonna pay in one way or another. Some will be right now (cash) and some will be down the road (decreased engine life).

Anyway, thanks for being on here, Stephanie. We all really appreciate when you guys share info with us. Happy New Year to you and the folks at BEGI!

 

[Pololo_MS3]

The Knock Sensor is just a microphone that is plugged into the block (via a connector) that listens for knock and then retards timing to avoid the harmful detonation.

I didn't know that MS3 has a wideband O2. I thought it has the common Narrow type O2.

It seems that you are able to datalog with a serial port (USB) through a laptop and this way change the parameters as needed. However, if these "numbers" are not stored in RAM (ECU memory) then how could these numbers change and still be undetected by a scanner when brought back into the dealer?

Guess I need to study as to how XEDE works. If the ECU parameters don't get changed, then this is still a fancy piggyback(no harm intended by this BTW).

A trip to BEGI is in order especially since I live in Austin. Perhaps I'll get a better idea of how this is being developed.

Funny, last night I found myself wanting more as my right foot was all the way down in the accelerator and there was no more travel in the pedal. At that point, I felt that my RX8 had more power.... lol

Ken / stephanie, does the XEDE have the ability to auto-tune to a set AFR based on an auxillary input given by a WIDEBAND o2?? That's a feature I like about the e-manage ultimate and AEM on other cars.

It woul dbe nice for someone on the stock turbo with bolt-ons to be able to set their AFR and ride.

 

[StephanieT]

We used these nifty little headphones with a microphone laid in the engine bay so that it was easier to hear. It looks silly sitting there with headphones on, but it works.

We recommend the Radio Shack Serial/USB connector is a serial port is not available.

The ecu signals going in are modified, however still within the "normal range" the ECU will allow without throwing a code. So until a code pops up, you would never know it is there. There is not very much changed at idle on this map. For the most part it is really close to stock. So unless the dealer tech. goes out for a joyride and/or sees the unit, he will never know it is there. The Mazda stock ECU maps are not changed. The Xede just tells it to look in a different place on the stock map based on the "adjusted" signal coming in. If I have just totally confused you, sorry, give me a call and I can explain how it works better over the phone.

You live in Austin and have not been down to visit???? (poke) The Tejas Miata club comes down regularly to visit.

Yes it does. We are some tuning with that set up this week. Technically, it is not an auto tune like the emanage. It has an additional map set up that makes more fueling corrections based on the wideband signal.

I just moved here (3 months ago) from CA. After 3 weeks of being here, my RX8 got totalled (sandwiched) by 2 TX trucks!!

I might join the Miata club here as I don't see a need to join the Rotary club here. On top of this, I MISS my Turbo'd Miata and will be looking for one in the future (nothing feels as good as power oversteering with a RWD car)

Not anymore.

Amen to that.

Is there great torque steer now when you get on it compared to before?

[benzo]

Torque steer is the nature of the beast. Learn to deal with it, in my eyes. With all these different map talks and changing them with mods is getting me confused. I will have to call and talk to really understand.

 

[redms3gt]

Will exede remove boost reduction in regards to steering angle. Might give more tq steer but this thing really bogs out in the slowspeed turns.

 

[djdanny5000]

why is everyone so damn concerned about tq steer i mean look at the stupid srt-4 aren't they front wheel drive as well and those guys are pushng alot of power
