Still a bit confused.....
So you are saying you could have for example 8 lbs of max boost in first, 10 lbs of max boost in second, 12 lbs of max boost in third etc.
I still don't see how the XEDE can vary the boost from gear to gear. How does it know what gear you are in ? Doesn't it just know engine RPM?
Thanks in advance for explaining this.
We now have XEDE boost control working in both absolute
and intercept modes. In absolute mode, you simply input
your desired wastegate duty cycles as a function of load and RPM and
your factory boost control hardware does the rest.
In intercept mode, instead of inputting actual duty cycle values, you input offset to stock. For example, if you want 14.8% more boost , you simply put "14.8%" in the desired cells in your boost map.
In either mode, you have the ability to run a RPM-dependant boost profile of your choice. This is far superior to using a stand-alone boost controller,
most of which are only capable of holding one boost level all the way
up to redline. Also, the boost control logic in the XEDE greatly
improves both low RPM and partial-throttle boost response
and intercept modes. In absolute mode, you simply input
your desired wastegate duty cycles as a function of load and RPM and
your factory boost control hardware does the rest.

Ok so now I understand, boost is purely RPM dependent (XEDE does not know or care which gear you are in). This means the torque manipulation in 1st, 2nd & 3rd from the stock ecu are gone.Nutari said:

Oh yea, what determines if it's running in absolute or intersept mode ? Is there a switch or is this a software setting?

Holy s***, this is way cool!(first)

Btw.. I just got back from my test run. Watch for the write up.
the POWER is there folks. Its not just numbers.

So where is the review?? About time don't you think?

i dont know where you heard that out stock tiny little k04 turbo can produce 20-23psi ?! you could take the WG off the car and it wouldnt spool that high !! 16psi at redline is gonna be tops. sure there will be people dumb enough to try to push it further, but all you will get is hot HP robbing air.Anon Y Mous said:

eh, tell that to my local VW crew who consistantly run the K04's at 23psi (spikes) and settle to 20psi. Sure it's hotter air but thats what I've got a larger TMIC for.
it may be a larger trim k04, cuz this one would not do that..i promise !!Anon Y Mous said:
you would have more power with 16-17 psi than with 20-23.
even an IC upgrade wont take care of the EXTRA 100 DEGREES over working that turbo would create. just a fair warning, do what you want.

I have 2 questions:Nutari said:
1) When making user adjustments, how does one know when the onset of detonation is reached? Obviously this is very important to know unless one wants to damage their engine.
2) Exactly which ECU signals (input or output) are being modified or monitored by the XEDE?
