Default how to get out of limp mode

For engine management i have an ecutek reflash with xede on top of it. When i was tuned we couldnt get my avcr to work so we just used the stock boost control solenoid. Well after the tune i thought i figured out the problem with the avcr so i hooked it up and went out for a drive to get it dialed in. Still was only able to hit wastegate pressure. I then hooked up the stock solenoid and i still cant get over about .7 bar. Did my car go into limp mode of some sort? My friend said with his ecutek he had once overboosted and his car did the same thing until he took it to his tuner to get fixed. Is this something i can fix by myself or do i need to take it back to have them do something with the software? I already tried reseting the ecu and that didnt fix it.

Resetting the ECU should fix it.

If you disconnected the battery, then you may just need to wait a bit longer. I've personally disconnected it for ~15 seconds or so, and it wasn't long enough. Just wait a minute or two and it should be fine.

hmm who knows, maybe it isnt even in limp mode. I had the battery off for about 45 minutes and it still only hits .6 bar. Nothing else has changed so i'm sorta stumped. I guess ill take it to my tuner and see what he has to say.

found the problem. i forgot that the tuner put a boost pill in the line coming off my intercooler piping (compressor pressure) and when i hooked the lines back up i had the pill on the side of the solenoid by accident.

D'oh!

It's cool that you found the real source of the problem.

Xede over Ecutek? What advantages does that have other than dual map functionality...I can only imagine that being one huge mess. Maybe you can enlighten me?

Ive been running xede for a while now as my only form of engine management. Recently change my setup from a normal vf30 setup to the kingpin gt3040 setup. Also added the perrin big maf and pe800 injectors. With the big maf i guess the timing values were so high that the xede couldn't lower it back down so we had to reflash the ecu to lower those values then from there tune with the xede. Also had the change the dead time for the PE injectors so the idle would be better.
