Thx for the help

Mike,

You're going from a 2000 OS to a 2002 OS...

copy all the tables/parameters from the 2000 file to the 2002 file...

i.e. you want all your 2000 tables/parameters and the 2002 OS/algorithms.

Joe

Thx, That's what I was thinking.:)

And welcome to the forum Mike... :cheers:

Here's what I did:
- Set DTC & MIL to 00 settings
- Copied 00 Main VE, Injector Flow Rate, & High Octane Spark tables over.
- Enabled EGR (when I still had it)
- Did a comparison of my 00 tune to a stock 00 tune and copied my changes over.
- Analyzed various tables (e.g., PE RPM modifier, base line pressures) and used 00 values where I thought them more advantageous.

Did I forget something?

Thx for the info guys.
Ok I was copying parameter data where I could, table to table and I hit my first snag. B5911 SPARK IAT TABLE. My 00 reads in inHG, the 02 reads in oz/cylinder but the columns have different numbers. I assume because of the different calibration units. How do I deal with this and other similar tables such as Spark EGR correction which reads likewise. It must be built into the parameter tables. I tried to make them the same but no dice.

Some of the tables are different in the fact that they reference other parameters. What I did was start with the new '02 table and tweak it for personal preferences. Just be logical. I mean, unless you're running a boosted setup, do you honestly expect to see intake temps over 140*F? That'd be some major traffic jam in the desert on a blistering day. Then on the off chance you may see those IAT's, are you going to be the type of person to floor it?

Right. Just do the tables I listed and forget about the rest for now. Get your OS changed over and the car running. Most of the other tables will not differ significantly enough from one OS to another to have much effect on how your car runs. If after driving your car for a while with the new tune, you want to tweak something, then compare the old 00 tables and the 02 tables for information.

For example, I noticed that the 00 OS gave more base line pressure on 1-2 and 2-3, but 02 used more on 3-4. My tune combines elements of both. But you can do that kind of thing as you go along and get a feel for the new tune.

I compared my 00 tune to a stock 00 tune first - if the values were stock I kept the stock values in the 02 system also. I only changed the things that I knew had to be different - VE and Timing, speedo calc for the gears, DTC & MILS, etc. Everything that I could leave stock on the '02 system I left figuring that many of the tables interact so the fewer the changes the bettter going into the new system.

Thx for the help. I think I was making this more complicated than it needs to be. :Eyecrazy: I'm going back and start from scratch.

Keep notes on what you doing table by table. It's time consuming - took about 1.5 hours but worth it later when you say - hmm, why'd I do that?:Eyecrazy:
