New to EFI LIVE and struggling with COS upgrade

[Cyrperformance]

Been reading through the tutorial guides and about 1000 threads about upgrading OS and for the life of me can not figure this out. I have an LS1B OS 12587811 and see the custom OS files in my documents which show 0125001-3 then 0127, 0129, 0201 and so on but how do I know which is the correct one to use? I figured out the 001-3 at the end are the different options within the COS but can not figure out which is the file I would use. Under V7.5, Upgrade OS there is nothing listed so I'm guessing it would show in this box after you flash in the COS file but there again I have to ask which file to load? What is the guru secret to knowing what COS is for what?

There is a table matching COS to standard OS in the upgrade tutorial.
Tune Tool>Help>Tutorials>Custom OS Upgrade Tutorial - LS1.pdf. The 'Upgrade OS' tab is for later OSs where they are 'patched', not for LS1B.

However, for your particular situation, unfortunately there aren't COSs for the 2006 OSs.

Seriously, I can not run a 2bar OS off EFI Live? So depressing. Seems like everytime I think I can do something with one or the other software I get kicked.

If your OS is not listed in the LS1B Custom OS pdf then there is not a COS for it.

Seriously, I can not run a 2bar OS off EFI Live? So depressing. Seems like everytime I think I can do something with one or the other software I get kicked.You can run a 2-bar MAP sensor, and scale the VE and MAF tables by 1/2, and also you have to scale/shift any other tables referenceing airmass or airflow on their axis... it is doable without a COS.

[Cyrperformance]

So if it is not in the small list from 2001 to 2005 then it doesn't exist. So I need to start searching the whole scaling deal. Seems as though it might be easier to keep the LS jobs with HPT, we can upgrade to 1bar, 2bar, 3bar extremely easy.

why not OS swap to an upgradable OS?

[Cyrperformance]

Okay so I have read the custom os tutorial but can not really find anything in regards to OS swap. Is there any tips that can be shared? I appreciate the help.

[RADustin]

need to find a similiar OS that is COS supported.

The OS that you have, what did it come from?

[Cyrperformance]

2006 Cadillac Escalade, 6.0LQ9

[RADustin]

I would try this file. Then you can use COS 051200xx. Edit- I had '051300xx' here but I meant '051200xx' as what is in the tutorial.

This is from an 06 LQ9 truck. Compare it manually to your file.

[Cyrperformance]

Okay Thank You for that, but can you please tell me how you found that file? I am interested in the know hows so I am not asking the same question and learn a little more. Again Thank You.

tunefiledepot.com

search though it for the OSs you are looking for.

[Cyrperformance]

yeah I just looked at the one you posted and it doesn't have an upgrade listed under that tab. I think I'm lost and this is going to take a bit to get used to.

have you read that?

Get your current tune swapped into that new tune( update any tables that are different). Then tune your ecu with that new tune. Then flash in the COS from the folder in my documents, read it off, fix it up, flash it back in, make sure it still runs, then get to tuning.

Its so idiot proof it seems complicated at first.

[Cyrperformance]

Yeah I read that and I swear I read that you go under the upgrade tab and select the OS. They must have changed it since last night!:bash: Okay going to try this and hope for the best. Again Thank You.

[RADustin]

I think thats the 'updated' way but it has never worked for me.

[Cyrperformance]

Don't even have this 051300xx in the custom OS.

[RADustin]

the 'xx' is replaced by what COS number you want to run. If you want COS5 then you want 05120005. If you don't see it then make sure you are on the latest software.

I admit HPtuner is more noob friendly, but efilive has CAX capability which is epic.

[Cyrperformance]

I am on the latest update but do not have 051300XX, I have 05120001-0003. CAX capability, so I may cry myself to sleep tonight.

[RADustin]

yep so the beginning posts of this thread make since. no >1bar support for this ecu(or any 1mb). just cos1 and 2.

looks like hptuners is your friend currently.

[Cyrperformance]

Yeah, kinda sucks that I was all pumped up with HPT go to use the real time tuning and can not use with this controller which it confuses me that it will come up as LS1B sometimes then E38 others. So on to EFI Live and yeah, no can't use that feature. So it will be off to the dyno to spend some more money to nail this tune down. Time is my biggest killer with work being so busy I have no time and you can feel it has so much more potential but sadly it is neglected.

[RADustin]

well it is strange efilive just gave up on the 1mb cos3/5. this is all new news to me- I apologize for misleading you.


If you read around you can see where it was asked for but other things have taken precedence. Maybe since hptuners has a COS for damn near every ls1 OS EFILive has thrown in the towel on it?

[Cyrperformance]

No no thank you for the input and help.

[Cyrperformance]

Also don't know if I would say they threw in the towel, EFI Live so far looks like they have a bit more attention to detail in their software IMO. Diesels are a huge market and growing more and more and becoming harder and harder to keep up with. We will see.

[joecar]

Yeah I read that and I swear I read that you go under the upgrade tab and select the OS. They must have changed it since last night!:bash: Okay going to try this and hope for the best. Again Thank You.
That's for E38/E67.

[joecar]

I am on the latest update but do not have 051300XX, I have 05120001-0003. CAX capability, so I may cry myself to sleep tonight.
You should have both 051200xx and 051300xx...

[Cyrperformance]

Thanks we figured that out and it does say it in the tutorial, but also says LS so quite a bit misleading to someone new.

[joecar]

You can run a 2-bar MAP sensor, and scale the VE and MAF tables by 1/2, and also you have to scale/shift any other tables referenceing airmass or airflow on their axis... it is doable without a COS.
Have you considered this ^

[Cyrperformance]

I don't have the last cos number you posted for whatever reason, but the whole scaling may be a little to complicated compared to just using the HPT.
