Cliff notes: Took car to local shop for the first round of tuning, they played with the tune while I watched and learned.

I want to start AutoVE tuning on my own. I have all the PID's, Maps, and backups ready to go.

Should I use the stock unmodified 1999 Camaro VE tables or should I use the VE table as it exists in my PCM now (that one has been modified). When I compare the two tunes this is the info I get:

Comparison summary"03:47:53 pm, Wednesday Dec 27, 2006

Calibration comparison between 1999 Chevrolet Camaro Coupe Manual LS1 5_0001.tun and ORIGINALTUNE27DEC06.tun.

B0101 "Main VE Table" -4.0212 "Different from cell: 0,0 to cell: 18,19 inclusive." AND
B0103 "Backup VE Table" -4.0212 "Different from cell: 0,0 to cell: 8,19 inclusive."

I understand that with my OS I need to use B0103. My High Octane Spark table has been modified as well.

Also, am I to assume that the -4.0212% means the tuner removed "4%" from the VE?

Thanks for your assistance.

Ideally to start with you would be best to update to a 2001+ Operating System, which requires the Commercial version of EFILive to perform the full flash required. That will get rid of the Backup VE Table and also provide you with a more current base.

If you are wanting to stay in SD mode after tuning then you would also benefit from the EFILive Custom Operating systems (version 3 would be best) which will restore the High Octane spark table - running SD in stock OS runs ONLY from Low Octane table.

Enjoy,

I have the Commercial version.

I have read that I would have to manually transfer each table with my '99 PCM, which is why I am still using the stock OS. Call me "chicken"

I have been talking to Chad at GLM about buying a Road Runner and he has offered to update the OS and transfer all tables.

So.... should I use the factory '99 VE table values or the values currently in the PCM?

Thanks to all for the assistance.

shouldnt really matter to be honest...once you start VE tuning & get the cell hits required the cells that are different now will likely change anywayz.

Ok... I started to secong guess when I had to add 15% to the values.

Thanks again.

15% is suggested to play it safe, but likely too much. As mentioned the first few wipes of the correction will sort it out.

Gotcha. I am all set to give this a shot tomorrow after work. Too dark outside (and cold as heck) to be messing around now.

Thank you all for the feedback.

Check out www.holdencrazy.com. In the modified tune section, there is a stock '99 m6 upgraded to a 2002 m6 OS. You can use this tune as your base and transfer the tables your tuner modified for you.

Gotcha...

I'll give that a shot. Thanks for your help.

I'll transfer over the files for you now if you want. Just send me your current tune and I'll apply it to a 2002 OS.

Let me ask this.... and I am not trying to make this more difficult than it is.

On the Holdencrazy website it says 1999 tune "migrated" to a 2002 OS. So does that mean all tables have already been transfered over?

If so, I will download that and use the tune comparison feature and "copy and paste" the tables that are different from stock.

No, just that I used a bone stock 02 file for a 99 car. I didn't change any tables as it was a scratch tune. With yours you already have tables changed.

Fratsit

So I would download the 99 tune on the 02 OS and change the tables that my tuner and I have modified, then I can start the AutoVE tutorial and further modify the tables according to that.....

or (all things being equal) I could download the Holdencrazy "99 to '02 OS tune, do a full reflash of my PCM and my car would run.

Thats what I need to get clarified. That the 02 file is set up and ready to run in a '99 car (hence "migrated") and I would not need to transfer any tables manually (if the car where still stock.... I understand I have some data to transfer over in my situation).

Thanks for all the help and smack my wrist if I am making this more difficult that what it is....

Ok..

Just downloaded the migrated '99 tune. A quick look at a few of the tables and everything appears to be ready to go. I only need to update the appropriate tables with my values.

Thank goodness for 17in LCD laptop screens. Having the tuning tool open in 2 windows is a PITA. Looks like I will be heading to the local Starbucks so I can concentrate.... and the Eggnog Latte's arent that bad either.

to answer you question, yes the migrated 99 to 02 tune is ready to run on a stock 99 vehicle. And yes, you still currently need to open 2 instances of the tune tool and transfer over the tables from your tune.

Hey thanks. I just finished transfering over the necessary tables.

I really appreciate the assistance from all.

If your going to run without the MAF when finnished you should upgrade to custom operating system 03,
just choose the appropriate custom op sys for your new 02 calibration ,then do a full flash with custom Op sys, then a calibration only flash with your 02 file and your good to go.

Probably best to go to EFI download page and get a copy of thier Custom Operating System tutorial.

Custom OS is definitely a good choice just for the extra tables and features like valet etc.
