Do some of you guys tune your own Xede. I am trying to decide between a Utec or an Xede. My decision is swaying more to the Xede because of the available maps for it. I had my car Dynoflashed with a Base flash for my mods. I will be addidng HKS 264,272 cams and cam gears to my car. How can i compenstate for the ECU being dynoflashed.

 

WOW,

21 views and no one knows .

 

Kinda answers your question eh? Actually I've seen several threads of guys who are tuning their own Xede..

Unfortunately tuning on top of a reflash means custom tuning..

 

It's WAAAAY easier and WAAAAAAY better than the UTEC, for the street. Wanna race exclusively? Go for the UTEC. Nah, go for the XEDE...more tech, more friendly, and more better. Don't mess around with the old school crap that has been known to blow motors due to detonation. Either choose the XFLASH or the XEDE...I dare any UTEC user to beat the XEDE on the street. It is proven and it is the ONLY EMS I trust and I've had both the UTEC and now the XEDE. Just my $.02...but it's worth a million bucks.

Get the XEDE/XEDEflash combo ... I believe that should overwrite the dynoflash and set you up for XEDE only (double check with someone @ Vishnu though). It is possible to run the XEDE on top of a Dynoflash, of course, but usually that will mean a custom map. IMO with all of the available (tested) maps and the ability to switch between two maps at the flick of a switch, there's really no need to tune your own XEDE, unless you have a fairly unique setup and/or like living on the edge.

You have to send your ECU in for an XEDEFlash (its only $100 with an XEDE purchase) to overwrite the Dynoflash so you can begin tuning.

I've tuned a couple of them- Very simple and straightforward. You'll need access to a dyno. Other than that, its not too tough. The baseline maps Shiv provides make it so easy as a starting point.

 

i still gavent figured out if i canjust purcgase the xedeflash alone for the fuel cut.

 

get the Xflash!

 

neh, i dont see spending that much money just for a flash, when all i want to take part of is the fuel cut part, an xflash would be a waste for me when I plan to get an XEDE.

 

In all honest it's easyer to tune the Xede just because of the 3D graphs and offsets instead of direct Ignation timing. Plus full factory knock control for the extra margin of safty. When the data logging and Wide band input come out it's over. More people will be tuning it and as of two years Xede has been the only system in the market that has not had any problems runing with the stock ECU.

UTEC had A/F mapping issues

I agree with the comments about starting from the Vishnu maps with a known base ECU map. My car is currently somewhat outside the traditional Vishnu stages with Piper cams and a K&N intake. I'll probably be taking the intake out shortly, but I'm in the process of having my head ported and oversized valves installed in preperation for a turbo upgrade next spring.

As long as you have access to a decent tuning facility making adjustments is pretty easy. The software is easy to use and very flexible.

 

I tuned my own Xede. I have a dynoflash and I really like the low end tq hit compared to the vishnu tuning so I have both Top end is great now and I haven't been beaten by any evo with equivalent mods yet.

If you keep both, you are really only going to be tuning the AF. Al's global timming corrections pretty much negate any changes you'll make to timing. Works well enough for me right now. I'll eventually sell the dynoflash and get it Xflashed one day.

 

That's a lot of monkeying around with the sensors. Since the XEDE can control boost 100%, having the dynoflash in there is a waste. You can make your XEDE stronger than the reflash in the low end and midrange, you just need to tweak the XEDE's boost settings on the dyno. Having a reflash that controls A:F and timing as well is a piggyback is kind of like running two laps in a one lap race. Its better to run one great lap.

Cliff's notes: Get rid of that crappy baseline and start from scratch. You'll make more power everywhere and won't be trying to manipulate sensors that have already been manipulated.

 

Noize, I am well aware of the setup that I have and what I expect from it. I did get the Xede to one day upgrade to the Xlfash, but as of now, I am enjoying my car and its performance. I do not find the dynoflash, in my particular case, to be a crappy baseline. Hell, I beat TWO custom tuned Xedeflash cars with just my "crappy" dynoflash mail-in from a 40 kick up to 85-90 on several occasions. Perhaps I am lucky and have a strong car. Either way, when I upgrade the cams I'll probably ditch the dynoflash then.
