Default GIAC J31 K04 Programming

After seeing mmart6545's dyno data recently, it made me wonder if GIAC defeats the throttle cut/limp mode on boost levels over 1.45 bar somehow in their programming. Seems like they would have to in order to maintain boost at those levels.

I'm running the GIAC CHK01a K04 program on my '01 Passat and it runs great. Below is a link for a recent data log of block 115 and 003, 82F ambient temp. Similar question as above. Do they defeat the requested/actual boost deviation that I thought was in most programs?

Any thoughts would be appreciated.

Yes, that's one of the shortcuts he takes.

Default The throttle cut wont happen till you sustain more then 1.5 bar of pressure at the boost sensor.

I dont think GIAC used any codes to disable the throttle closing feature on anything other then the 2000 A4. Since that was something he worked on with my custom chip back in 2001. He was able to run 1.65 bar of boost out of my K03 on 91 octane without the throttle closing, that same chip was then used to produce the K04 chip for the 2000 which ran 28+ psi.

The Xchip for the 2001 A4 runs 1.2-1.4 bar of boost and should still have the throttle safety feature within the programming code.

Default is the 1.55bar limit a result of programming? or the physical limit with the MAP sensor?

and i wonder how long that boost level has to be sustained to get throttle cut. i was spiking past 1.55bar and getting tc, so i dont think it has to be sustained necessarily
