Hi all,
I'm currently running tunerproRT with an Ostrich 2.0 in my GM 5.0lt V8 (oz engine) and wanted to try tuning in open loop (no cats)but for the life of me i can not find the flag or constant like it's easily seen in the 165 and $6E.
Would anyone be able to point me in the right direction of where to disable closed-loop and how to adjust PE.
It is a SD setup similar to your 165 ECU.
Thanks for any help...mario
This is my set up:

 

I may not be correct, but I don't think there is a flag to turn CL on or off. Instead, you adjust the CL temperature to something way high, so it never goes into CL mode. There should be a setting somewhere for the CL temperature, I think stock is something like 110 degrees. Someone correct me if I'm wrong though, I'm not 100% sure.

 

Thanks Ward,in item find there are about 10 IAC closed loop parameters and 2 flags...KOPTFLG3 and 4 and thats about it,but cant put my finger on it.
Hoping someone could D/L my bin and Def and see what they can make of it.
Thanks again Ward...
Mario
