Who wants dibs on the XEDE PnP System?

[StephanieT]

Need Specifics! Just saying it is more $ does not do much.

I read a post by a CPE employee that says it cannot control fuel at cruise conditions or at idle. Is this true or application specific?

i dunno, i never really got into either unit. i just know both control the same thing and one is cheaper than the other.

And therein lies the confusion. People who do not know specifics are out there making claims about X and Y product. And it is usually not accurate. That is the reason I will never say anything about someone else's product they have not already said themselves. I realize the Xede is new to the Mazda application, but that does not mean the extra money is not justified. There is a way to tune a car for power, and there is a way to do it for efficient power. We prefer efficiency and think that most will also. If not, there are always other things out there.

The standards for efficiency #'s:
Below 8 - Awful
8.0 to 8.49 - OK
8.5 to 9.0 - Good
9.0 or Greater - Excellent

Our Car: 288 whp @ 16 psi - 288/ (16+14.7)=9.382

Dyno Sheet recently posted on Web: Boost level was not specified, so both are listed.
253 whp @ 19 psi - 253/ (19+14.7)=7.508
253 whp @ 15 psi - 253/ (15+14.7)=8.518

If I was tuning a similar car for someone else, I would leave it de-tuned to 15 psi. Better fuel economy, still enough power to feel the difference, and less wear on the engine.

So you aren't going to justify the 400 dollar price difference, your just going to tell us to take your word for it? I think you should justify it, it seems like gauging. If the best you can come up with is controlling something at idle, I think I will head on over to CP-E.

Like I said, Give me a specific List of what the CPE can do and how it does it and I will compare it. There is not enough info listed on their website. What is the cost per horsepower gained? What is the cost of the CPE unit?

The only things I have read are about the method of Boost control and the lack of fuel control at idle and cruise. The boost control method works, there are advantages and disadvantages. Just like an boost solenoid. Neither is better than the other, but they both work. The lack of fuel control off of idle would not be good. A larger exhaust or downpipe will affect cruise fuel trims and fuel economy. One really needs to be able to adjust that.

According to CPE's website, the piggyback costs $640; and thats to be hardwired in. If they follow the same setup as the MS6, then you will have to pay an additional $399.85 for the PnP feature... Thats a total of $1039.85!!!

BEGi Xede is $899 and if I read correctly will include PnP...

So who is more expensive...?

(Stephanie, am I correct will my understanding with the pricing of Xede...?)

I thought laloosh did, but oh well.

I thought laloosh did, but oh well.

I want specific info on how it controls fuel and timing. I have read about the PID boost control. I am pretty sure they tune via fuel pressure. That has it advantages and disadvantages. We have configured the Xede to tune via MAF and Fuel pressure at the same time with no real benefit. How does it control timing? Does it control fuel during closed loop? What are the other features? Map switch, etc... That is the type of info I need.

ill will most likly be able to help you out by the end of this week. My ems is getting dropped off today by the friendly ups man. I will play with it all week and see how everything works, or at least try and see how everythign works. From what i read this isnt the easiest thing to comprehend as it controls ALOT of things. go to cpe's website, under the speed 6 they have a bunch of screen shots and more info on how things work.

 

[SAVAGE70]

Can we expect the XEDE PnP to be out by the end of this year? Also could u tell me if the connectors off of a CX7 ECU are the same as the connectors on the MS3 ECU the same? Or would the MS3 ECM connectors be the same as a regular Mazda 3 ECM?

Can anyone confirm this...?

 

[pHeeL tHiZ ViBe]

the rumors hold true to date...but cp-e is smarter than that and the market is small. so i doubt it will turn out like that.

The standback a can adjust the maf voltage and fuel pressure in closed and open loop, those adjustmants are made via a voltage multiplier-not based on rpm or tps. The primary and secondary fuel and timing maps are adjusted by an RPM vs. TPS grid--I don't know the actual method they use to effect the fueling changes though.. The timing changes should be maintained during closed loop, but the fueling changes will eventually be adjusted out by the ECM via the long and short term fuel trims(during closed loop driving). I can see this very easily on my motor-if I reset the fuel trims(disconnect the battery) my wideband will read at 14.6~14.7 at idle and cruise, but over the course of about 100~150 miles it will trend twards 14.1~14.0 at cruise and idle(I have replaced and recalibrated my LC-1 sensor, so I attribute the gradually richening AFR to the stock wideband sensor calibration drifting).. Regardless of the feul trims effect on my closed loop running my afrs at WOT are fairly consistant around 11.8 until about 6k where they take a nosedive into the 10'a at redline...

Interesting, it's missing the "Plug 'n Play Wire Harness" part for the Speed3....

BRING ON THE XEDE W/PNP STEPH!!! ;-)


Anyways.

I'm waiting patiently for this, so yeah, I just may have this on my Christmas list for santa!! lol

**Right now, the plug 'n play harness is not available for the MS3. We anticipate delivery of the PNP patch harness in late 2007. There has been some confusion between the parts manufacturer and assembler as to whose part it is to sell. Once that is straightened out, the connectors will be made and shipped. **

hoping late 2007 doesnt move to early 2008 then mid 2008

GARR DAMMIT!! LOL

yeah, hopefully we get it sometime this year?

Stephanie!!! Come on girl...we are dying to spend some cold hard cash here!!
Start cracking that whip and get the PnP harness out!!!

(2thumbs)(lol2)
