Limp Mode

Limp Mode
Here is my dilemma.
im boosting 17-18 psi at 3k RPM. i have the wastegate control set so i spool up faster too, now it runs fine no problems but it will be intermittedly. its wierd, sometimes it loves the setting and other times it keeps going into limp mode.
the limp mode will last for maybe 5-12km and then back to normal boosting 17-18 and then later on again same thing.
sometimes the intervals are hours , sometimes 10 times in an hour, or sometimes days in between.
so that brings me to this question: How can i elimante/manipulate/override etc.the limp mode to boost a proper 19-20 lbs on my k03

no, there is somehting going on. it should not behave in sucha fashion. the onset is set very mildly. i just set it so i dont have to mash the gas pedal in order to acheive full boost.
besides, im trying to acheive a max boost of 19-20 and i want to hold at 17 . in order to acheive this i need to get over this hurdle because it has capped me without any opportuninty for growth on that #

get a software upgrade..
or get a diode so the ECU never sees boost above 15psi.

it appears that this is an isolated incident? I am sure that this problem has been encoutnered and conquered. Some direction would be nice.
I didnt think that the ECU can adapt itself out of "LIMP" mode unless the codes are cleared or if the battery is reset. Maybe but I have heard of guys driving around in limp mode for weeks. Wierd

Diode mod is instead of chipping.

The diode will keep you from going into limp mode because cranked boost levels far exceed what any chip is written for, even GIAC X+.

i want to avoid adverse affects of having conflicting systems.

Do you get any check engine lights when the boost drops off? Or anything at all, just curious and it may sound dumb but have you checked for any boost leaks ever?

the connection to the boost gague is a little funky i reseal it every few weeks sincethere is a little whole at the boost T. Im getting the 42 draft design boost hosing kit. it should be en route. .. actually im gonna check the trackign # right now [:-]lol
anyways ... no Warning lights at all. i was reading on a Vortex thread that the EGT sensor will nto throw a visible code if it is malfunctioning. but i need to get a VAG to it which is also on theway, need to check the tracking on that too lmao ! [8D]
im gonna see if my buddy at his shop can check it for boost leaks, but i doubt that is the issue otherwise it would not be consistent.
