XEDE Engine Management System Available Soon!

Thanks for the updates. After coil overs next month (hopefully) I realy want some more power to play with this summer, or end of summer by your schedule.

We can basicaly "set and forget" on the Xede correct?

yes it comes with a very good and streetable base map. for the best results when you do more mods you'll want to have it tuned or tune it with the XMAP software.
 
So quick questions, how will the maps compensate for altitude, and climate changes?
Say the streetable map for a stock MS3 has been made at see level, where i am in SLC, you would/should run uber rich compared to sea level.
I only ask because my previous experience with a piggyback had this issue, and i don't want to be driving around with my laptop plugged in every week trying to iron out problems.

Will it come with a map geared toward maximum fuel economy? I know, silly question with this car. If not, would it be possible with the XMAP software?

sure its possible, but you'd want to be careful not to pull out too much fuel and run the engine too lean. honestly the system is really geared towards making power, and you might find yourself putting your foot into it more with the added power. definetely not good for fuel economy :)

the XEDE is an interceptor system, so the ECU's own correction factors will apply themselves.
 
Woot, bought one, thanks BEGi/Ken. I wish it came with a free copy of Corky Bell's book, Maximum Boost
 
I was wondering, with the XEDE system, and the fact it changes boost pressures; using the supplied settings it comes with, will I have any problems with the stock bypass valve, as far as leakage? The reason I ask is I'm trying to only get performance mods at this time, and only later when I start playing with the rice side of things, or boost more, will I change things like my bypass valve to an aftermarket bypass. Mind you the stock bypass will be on a Injen CAI, but I don't see that making a difference.

Sorry for posting twice in a row, although notice the time difference. :P
 
I thought i read the stock bypass valve is good to aprrox 21 psi, the only reason people are changing it out is for the sound...
 
that's what I figured, just got thrown off by online retailers claims of "replaces that cheap plastic bypass valve that's prone to boost leakage, and get this [super duper woosh cannon!]" ... you know... just to paraphrase XD

....wait here's the direct quote from a retailer, whom I won't name..

"...The HKS Super Sequential BOV kit replaces the factory plastic bypass valve which has been known to rupture under boost. The HKS blow-off valve is machined from billet aluminum and is polished for an attractive and high quality appearance under the hood. Not only is the HKS unit more attractive, it also is more robust, and will not leak under high boost conditions, thanks to its unique pull-type actuation..."

I guess if I read more closely I would have understood more, I understand now that I know what to look for.

This retailer was more down to Earth, and straight forward about the same thing.

"...Universal billet aluminum blow-off valve made by HKS. The BOV utilizes a dual valve system to ensure quick response and complete closure during idle..."

I <3 them.

i got my hks bov kit from mcp-e for 291 its cheaper now like 260 i think..im not too sure check there website...the kit is the best ..comes with everything you need so theres no need to shop aroudn for flanges and recirc fittings
 
I don't see a point in buying it if there is no performance gain, at this time for me :) 260 $ better spent on motor mounts. It being the BOV.

well if u get the piggy back ecu im sure boost wil be a problem...if it doesnt show right away eventually u will need to change the plactic BPV...figured id get this and cai seeing as they are the easiest mods other than shifter bushings and s***...xede spikes at 22 and holds at 18psi wouldnt that be a problem on the stock valve? i think it would be...(usa)

the only XEDE-tuned car that spikes to 22 is our speed 6. The XEDE tune on the speed 3 only spikes to around 20~ and settles at 18.

o ok...would the stock bpv endure alot of stress at those psi levels?...causing the need for bov upgrade?

I've had the XEDE on almost since I bought the car (December) with no problems.

Have you done any tuning or are you still running the base map on your car? Also, do you guys have a map yet for CAI, or is the stock map the same thing?

I've said in a couple different threads that ive done tons of dyno tuning (30+ runs) I have a couple different maps. One that is a little too aggresive for higher altitudes (I went over the mountain and hit fuel cut several times)

Need to make a map to take advantage of the CAI.

Next step is to up boost/retard timing/add fuel.

I missed your tuning references. But thats good youve been messing around with it. I live in NC and spend alot of time in the VA mountains(1 hr north), to and from the inlaws. Mountain fuel cut might be a problem. lol. Do I order this thing from Protege or Begi? Or does it matter? Also, can I get a different map flashed at the time of purchase?

I noticed in the your "How-to" thread, that you said you spliced all the wires together and it looks factory(id love to see pictures). Would the dealer still obviously know this had been done? It seems like you dont care as much about that aspect, but what are your thoughts on this for those of us who do?

Im tired of waiting and I want to join the Xede club. Im almost to the point of pissing on my warranty, but I dont want to do it unless I have to.
 
seems to be running okay on stock BPV right now, I'll let you guys know.

Need to take pictures of the new setup.

I have a few new maps available. Still need to get a new one made to take full advantage of the CAI.

You would buy it through us.

Depends on where you hide the unit. The wiring all looks factory. They would just wonder what that box is. One of my customers/friend hides his in the battery box.
