Chad, thanks, that was it. :cheers:
Thinking about it, it must be how a new install of a COS forces you to set values in the new tables.
Edit: or it could be what was in the flash from previous non-COS (12212156).

Glad you got it figured out. :)
My PCM is currently running 12593358 -- I am trying to find COS5 for this setup. From the old COS3 tutorial it looks like I need 02040005 but I couldn't find that OS anywhere.
Am I correct in assuming that I should just flash over to 02020005 (hoping I got that number right) and then copy/paste my tables from the old 12593358 tune into it? If so, are there any particular tables I need to pay attention to (obviously timing tables, VE, etc.) or is it best to just copy/paste everything?
Also, is the official download link the one buried in the middle of this thread?

Thanks in advance.

If you want 02020005, then that zip is only one part of it (that zip file corresponds to step 0 below).

Thanks,
I am not sure what the difference is between 02020005 and the other 0005 OS file. Any advice on which to use is appreciated. This is going on a 2003 Z06.
:cheers:
There is no 02040005...
You have to copy your old tables to 12212156 and full flash that to make sure it works.
If it does, then full-flash 02020005, and then cal-only-flash from 12212156.
The other 0005 OS is for Australian PCM's.
Thank you joecar! I was thinking along those lines but didn't know the specifics of the upgrade path. Got all my tables copied over tonight (I think...) which was not difficult but sure was tedious. Going to reflash tomorrow and see how the car drives.
Is there anything I should be looking for in particular or is this just a pass/fail on whether or not the car drives at all with 12212156?
Car should drive the same with 12212156 as it did with your old OS.
I just did the conversion from the 99 Vette to 2002 Vette OS, that was the easy part. When I flashed to the 12212156 I had to resest the oil life and do a Crank relearn, once that was done, seems to work good, put about 50 miles on it so far no codes.
I am have a bit of trouble getting the COS5 to work NA (not using the FI stuff, just N2O monitoring).
Just down-converted from my 2003 OS to the 2002 OS 12212156. The car drives just fine. It's also one of the most beautiful days we've had here in Southwest Florida for a LONG time (cool and breezy 75 degrees outside, compared to the 90+ degree weather we've had lately) so it was nice to get the Z06 out and drive a bit. :rockon:
I did have to reset oil life but did not have to do a CKP relearn. During flash EFILive told me all CASE data would be retained and that was correct.
Now once the car cools down the 2bar sensor is going in and I am flashing to COS5 tonight! :D
Anyone have the P/N for the little gasket that goes on the MAP sensor and keeps it firmly in place on the back of the intake? I noticed the gasket on my old MAP sensor was torn in a couple of places while removing it.
:cheers:
Why did you have to downconvert from an 03 OS to an 02 OS? Is there not a COS for your 03 OS?
From what I've gathered, there are only two different versions of COS5 -- one for US spec cars and one for AUS spec cars (did I get that right?) The one for US spec cars is a direct upgrade for a specific 2002 OS, so converting to that OS first and copying the tables over makes the actual COS flash pretty straightforward.Quote:

That's correct: 12212156 -> 02020005
OK, I guess that makes a lot more sense than having about 205484 versions for each and every OS from 02-07+.:bash:Quote:

Brains, see attachments (...zip file failed to upload...)...
These were gotten by following post #204: showpost.php?p=46950&postcount=204
Edit: These files are already included in the later builds of EFILive software.
Ahh, thank you very much !! I skimmed this thread, and went right over it. :cheers:
Was the tutorial ever completed for this or am i over looking it? I am having a bit of trouble following the info in this thread :)
..RJ..
This thread contains the info required if you want to run the TPS vs RPM VE table (if you have a cam with much duration/overlap giving you poor vacuum, or just for kicks :D )... a.k.a. alpha-N.Quote:

Please somebody correct me if I am wrong but, does COS OS#5 exist for 2003 or +up? Any plans? I've got a truck that needs support for the juice.
So, basically in COS5 there is no way to run the car a little richer during warm ups? Because {B3605} has been altered.
I was wondering why our cars do this from the factory??Quote:

So, it's more of a safety feature. If you're going to be dialing in the tune and monitoring it every now and then, I don't know if you really need the factory safety feature of richer AFR's post startup.
That's what {A0008} is for.Quote:

Right. Well this depends from motor to motor. Some carbed cars had chokes and some didn't. I don't even think race carbs have them at all. Forgive me I haven't touched a carb since about 1998. Good ridance really.Quote:

Anywho, the theory that you are talking about hmmm I guess it is kinda of illusive. I was always told that it takes more fuel to start the engine + the heat of the engine helps to evaporate the gas. Pour more fuel in seems like it would just saturate the situation even more because the cold air can't hold as much vapour anyways. :nixweiss: However, I think my AFRs are leaner until the car warms up.
The problem I am having right now is that I have ran and ran the AUTOVE and each time I start the car it runs very lean but eventually goes to acceptable levels.
Attached is my note taking while reading thru this [long] thread.
For COS5 cal/tun files, see here: showpost.php?p=50208&postcount=218
Edit: the files are already included in the later builds of EFILive software, do not copy them from that link.
Can COS5 be used to add timing when PCM pin #56 is grounded instead of pulling timing for the Nitrous?
Id like to add timing when the pin is grounded for my methanol system and then go back to normal spark timing without the meth.
Looks as though minimum advance is 0 and upper limit is 20. Description say the value is subtracted from the final spark value.
Would it be possible to get a COS6 and just modify the timing to allow positive timing instead of subtracted timing?
Thanks Joe very handy...... :cheers:Quote:

By the #'s I thought I was looking for 02040005 but it seems that someone else had the same problem as me...IT DOSEN'T EXIST.
Now, my pal Howard e-mailed me a COS 5 but it appears to be an automatic calibration....I need a stick.
Now, I'm a bit confused....I've gone though a vast library of "original GM bins" and tried everything from 02-03 ZO6's and even a bunch of other LS1 standard shift bins and LIVE tells me none of them are compatible with COS5.
Are there rules somewhere I neglected to read???:bash: I'm sorta following the COS upgrade chart (os5 is not on it yet) and not getting this.
Does anyone have an stick shift ETC that works in custom os5..????Preferably an 02-03 ZO6 bone stock calibration....I'd rather not have to un-do someone elses tune.....
Thanks

COS5 is only available presently for two operating systems:
- 12212156 (2002 F/Body) = COS5 02020005
- 12225074 (Holden) = COS5 01290005
Hey guys.....
In COS5....I've had success improving the VERY cold start up by trimming the fuel in A0008 (open loop ect commanded fuel multiplier)
I was able to EXACTLY command the startup AFR and the thing starts AMAZING even when it's cold as hell....
But, In driving it today, I think I noticed my fueling was off and it ran bad.
QUESTION: is A0008 used for warm-up AND WOT conditions??
Do I need to bring PE in sooner to fix it? I seem to remember something about the pcm using "whichever is richer" PE or open loop commanded....
How does it work in COS5?

Is your problem final commanded fueling or final actual?
I would like to know if any of this OS's have the ability to change injector balance, to add 1% to cylinders 7 and 8 as we have the ability on LT1 engines.
I do not think so. At least I have not seen anything on this.Quote:

can we have OS 5 in the downloaded install OS folder to make it easer ,save having to place os5 in there after an install . i would say most people in OZ would use os5 as the base ls1 os
Geoff
I have been using for a LOONNG time COS5 with ETC, although this is a 512kb pcm...
