More COS5 questions
I have never attempted a COS before I have read the tutorial millions of time now and feel comfortable to do it to my truck. Although I was looking more into the COS5 for the Nitrous controls. Here is what I found:
My OS 12202088
My choices are 012500xx (either 01,02,03)
I was reading another thread here in which I think he flashed in another OS (12225074) then ran 01290005. I am looking for more information on this please. :banana:
I also noticed a lot of talk about tps ve table I wish not to use this I take it this is something that can be enabled and dissabled. Is this a varient of Alpha N tuning?
-
TPS VE can be disabled.
I switched to 12212156 and then did COS5. I don't think it really matters though.
-
For COS5 you need to first swap to OS 12212156 as ferocity said.
TPS VE is alpha-N (alpha being throttle angle, N being engine speed).
TPS VE can be enabled any time provided you populate the TPS VE table with values obtain from your corrected Main VE table (using the pid GM.VETABLE_DMA).
-
Ok so just go under EFILive>V7.5>Calibrations>LS1B> and select 12212156 OS and full flash it like a COS. then retrieve it and open my original cal and flash it?
Will there be map addressing issues. (I wish I could find the other thread to look over the issues he ran into it.)
Then repeat for going to COS5.

Take the 2002 Camaro 12212156 tune file with the same transmission as yours, found on www.tunefiledepot.com
then manually copy any non-stock tables from your 12202088 file over to the 12212156 file (open two instances of the tunetool);
then full flash the 12212156 file into your PCM, make sure your engine runs same as previous;
then follow COS5 procedure (full flash 02020005, cal only flash from 12212156, fix OOR cells, populate B3647 and other tables).

Thank you Joecar, I will do this tomorrow and post results.
This may be a dumb question I have herd reference in other threads to "OOR" but don't know the meaning sorry.

Out of range?
When you switch to the COS you will need to go through the tables and fix values that are out of range. Some you will have to make lower/higher and the max/min, save, reopen and set to the max/min in order for the tune tool to not say they are out of range.
-
Yes, out-of-range... (those cells will have blue dogear corners)... to fix those set them to max-1, save file, exit tunetool (important step), re-start tunetool, set those same cells to max (what ferocity said).
-
I take it some of these will not be used in my ecu thus is why they are getting set to max?
Also the file i found was for a 5.7l i take it doesnt matter as long as i copy my origanl maps and data into the spots that are changed such as Maf curve, temp settings, VE, PE and so on.

When you flash in COS5 and then read the tune off the PCM, there will be many values that are out of range that will need to be fixed. Also if you want to disable certain features then the corresponding calibrations will need to be set to the max or min values.
