Xede pippgback ECU is now available see http://www.xede.com.au/Vehicle%20HTM...50Z%202003.htm with good results,anyone likely to try is mod?

Where are the results?

 

The web site offers no info!

Who are these people?

 

Zuff the web site provides heaps of info. But nothing that helps us

 

Rang ChipTorque this morning and spoke to Matt 07 5596 4204 this is a summary of the discussion.

The unit "Xede Processor" is a ECU piggyback, developed there in Qld Aust., they are getting between 10 - 12 RwkW with the fuel and ingnition maps they have for the 350Z and it can be further tuned by anyone with a laptop and the software that comes with the Unit. They have agent/installers in all states for those who rather leave it to the experts price $1395 fitted and tuned or $950 for those who would rather use their tunner of choice.

Ring Matt if you have any questions.

David

 

Thanks for the info.

I would be interested in this but I need to do further investigation with my tuner. I cannot tune a car if my life depended on it.

If my tuner confirms that this unit has both the functions and resolution required for decent tuning then I will put my hand up for one of these.

Will let you guys know how things pan out

 

Sounds a bit like Powerchip Except Powerchip don't have the ECU but re-write the Stock ECU.

if the Xede said it will gain 10-12 rkw. So it will be aroud about 20 kw flywheels?

This is nothing like the Powerchip believe me I've checked it out, Powerchip reflash your current ECU where as Xede is a piggy back unit and can be tuned on the dyno by most tunning shops, so when you add that nice new set of headers + high flow cats, it can be re-tuned to get the most out of your hard earned cash. The other nice feature is it leave's the factory ECU untouched, plus it's an Aussie made and supported product with continuing development.

PS: At this stage they can't up the rev limiter!

David

 

Unfortunately while it could be tuned by anybody with a dyno you really want it tuned by someone with experience with that particular device with it's this XEDE, Motec, Autronic or Haltech etc. In this case that limits it to Chiptorque for tuning.

 

Agreeded but some of the top tunners are good are several brands of units, the price of the unit includes the program for the 350Z that ChipTorque have developed so you have a good starting point if you wish to fine tune it further thats up to you.

They have tunning shops up to speed with the Xede in most states that ChipTorque can recommend, give Matt at ChipTorque a call on 07 5596 4204.

David

 

I know the local ChipTorque place. They did the initial tune on my MX-5 many years ago. It was a conservative, safe tune but very very rich. I would have reservations about using them again if there was any other option.

 

FYI the US is also developing the Xede piggyback unit check this thread https://my350z.com/forum/showthread....hreadid=51393.

I know, I know Shiv. He was the first to crack 300rwhp on stock internals in his Miata way back when that was a big deal. I'm interested to see what they come up with but at the same time I have my reservations about this unit.

I've heard rumours of a Power FC coming in the new year but really I think the solution is going to be the one I didn't want. Get a real ECU and use it for fuel and ignition only.

 

Hi guys,
FWIW, we're the sole North American distributor of the XEDE. We work closely with Chiptorque in developing and testing applications for cars on this side of the pond. So far we have XEDE applications for Subarus, Mitsubishis and now Porsche and Nissans. The easiest to get ready was the Nissan 350Z XEDE due to the absence of a turbo. But since the XEDE's hardware and software have been developed on turbocharged cars, implementing things such as MAF scaling (for upgraded MAFs and/or larger injectors), boost control (both closed loop and open loop), water injection/IC spray, additional injectors, etc,. on the 350Z was a snap. Within 20 dyno pulls, the entire car was mapped to max power with none of the associated drivability issues typically found in stand-alone applications.

Regards,
Shiv

Have you been able to lift the rev limit to 7100rpm with the Xede unit and can the unit be switchable for lower octane fuel ie have to maps one for the optimum fuel and the other when low grade gas/petrol (as you call it).

David

 

I haven't attempted to raise the rev limter since the 350Zs I've tested have all made peak power well before fuel cut. We might look into it if this isn't the the case with all cars. As for having two maps, yes, we've done this. On the pre-production car, in fact. One map is for regular 91 octance (the best we get in CA) and the other map is for 94 (91 mixed with race gas). We use a simple switch to toggle between them.

Shiv

 

Is this similar to Unichip?

What signals are you piggy backing, POS, REF, CAM etc?

 

This piggyback actualy sounds good. I can't say the same for Chiptorque.

Are they the only people who tune with the XEDE piggyback?

 

A question for someone who might know:

With the plethora of aftermarket add-ons like -

HiTech - 17 rwkw
ChipTorque or similar !$ rwkw
Cold air 2 rwkw
Filter - other stuff -

and so-on.

Can one expect these gains to be CUMULATIVE
or are they amortised somewhat by virtue of their
conflict/numbers or otherwise ?

With all the tweaks that I read one might expect
something in the order of 40 rwkw cumulatively!

What's the opinion ?

FROZZZZTY
(ho-hum)

 

CHILLY, Im afraid it doesnt work like that and in fact sometime mods can work in conflict with each other and give a negative nett result.

As well as that, you have to take into account whether the OEM part you are replacing is any worse than the replacement part. I think CAI's fall into this category. That's to say, as far as I've read there is very little improvement if any over the standard intake.

As always
