Aussie ISX 15 E5 SCR Delete/issues

[nvenn1]

Hi all
Have an aussie ISX15 E5 in one of my trucks. Doesnt do any on road work. Off road work only so is not subjected to running mandated emissions.

I will post all info below on ECM/Engine.

Had a delete years ago, then someone turned the adblu/SCR back on so cummins could do a rebuild on the engine, problem is they never cleaned the SCR Canister and it became so blocked it cause massive turbo back pressure issues. I have since gutted the SCR canister, but now obviously i am getting alot of Nox error codes and derates.

How do i go about deleting these, i do not need the SCR to be functional, hence why i gutted the SCR canister. As the Nox and SCR unit is seperate to the truck engines, can i just put block codes in with calterm on the 2 codes causing me derates? or what other options people suggest. Seen plenty of delete files out there for the ISX15-e5 but they are for engines with EGR, DPF and SCR. We dont run them here in Australia. Ours only have SCR (Adblu/Def)

This ECM has a factory 600hp/2050ft tune in it. Which is needs to retain as its a 170ton (370,000lbs) rated truck, pulling quad trailers in a mine.
