It seems worth more to sell the EBC and get some money back on it since the XEDE will be controlling boost really soon.

Yep

 

Mark - would you know if the boost control option be available with just a firmware update? I wish I could get ahold of Shiv... Im getting the Xede and getting tuned on June 28or 29th.. so I wonder if that function will be available by then...

Also Mark, when you got your Xede tuned, couldnt have you have hooked up an mbc or ebc and ran some higher boost than stock? what was the reason behind not doing so? im just curious

 

I don't know when it's coming out. You should probably call to make sure that it would be available by the time your getting it tuned. Since you need it by a certain date, that could pose a problem if it won't be ready. I guess you'll always have the EBC to fall back on.

I actually had a MBC to hook up to play w/ boost, but I didn't want to install one at the time. Shiv let me know about the boost control feature coming soon so I decided not to play w/ boost until a later date. The power gains were still decent, although I bet it would be a lot more fun to hold 19psi the whole way

Mark

 

Good question. What could cause a boost limitation? I guess it would be ok for the stock turbo if that exists, but if anyone upgrades that and wants more boost, then I guess an alternative would have to be used like an EBC.

Mark

 

I was just thinking the stock turbo is only so efficient at 22+psi so it wouldn't matter if the boost range was capped there in the upper range, but if a larger turbo is used, then a limited range of boost might suck.

My guess is that the XEDE will allow for a larger range since it should allow for stock boost levels as well as modifying it to increase boost.

I thought that Shiv's stage 0 XEDE tuning held 19psi all the way until redline. Is this not the case? If you look at the dyno graphs he posted that's where most of his gains are: after the stock ECU dials the boost back in the upper RPMs.

If his XEDE programming didn't change boost, what did it do? Basically just adjust timing?

 

Yea, I believe he kept stock boost curves with his initial stage 0 graphs....

I want to see what it will look like with 19psi all the way up.

I want to get tuned with Full Turbo back, Xede, EBC, and open air intake. And want to see some better numbers than 225 at the wheels...

 

Shiv, we need some answers bro!

 

Dunno what he uses, but I bought this for my Teg and it works great.

I'm testing the newest version of our XEDE firmware on our shop EVO. The results have been excellent right off the bat.

Yes, our XEDE now controls boost with the factory solenoid. I'm able to add or subtract boost level (from stock level) as a function of RPM and Engine Load. The ultimate range of allowable boost presssures depends completely on the factory hardware (solenoid orafice, wastegate spring pressure, etc,.) But, as it stands, I can run as little as 10psi or as much as 25psi at any engine speed I want (with the limits of the turbo, of course)

The newest version of the EXEDE firmware also allows for realtime map switching. Basically, you can store two maps in the XEDE and toggle between them using a simple toggle switch. One can have a race gas map and a regular pump gas map depending on conditions. Each map will offer different fuel, timing and boost tables.

So far, these new features are available to current XEDE units through a simple firmware upgrade which they can do by using our freee XUpdate software (downloadable off the website). Or, of course, they can ship it back to us and we can do it ourselves.

We plan to test the new features in our shop car for a couple more weeks before it is released to the public.

Not sure if that answers all the questions. If not, fire away.

Cheers,
shiv
