Convert 2000 to 01 or 02 system

So the MIL and DTC settings your talking about are the Engine DTC processing enablers and Engine DTC MIL enablers , parameters?
The transmission DTC settings seem to be the same.

Another wierd thing in the speedo settings: My stock tune is saying the tire diameter is 24.91 in, but shouldn't it be 25.66? I'm now running 275/35/18's which figures out to be 25.57. How is the stock tune off that much?
Thx, Mike

'99 A4 (OS 09381344) to '02 A4 (OS 12212156) files

I tweaked a few things. But, it's pretty much a straight copy of every table that could be copied.

Mine was the same, and the speedo seemed to be OK. Easy enough to modify if the speedo is off whenyou're done.

Yes, the DTCs etc. from the diagnostics section.

So if I have a stock 00 tune I can pretty much just use the stock 02 tables?

I think you need to re-read this thread...

I think there are some tables that are interchangeable. They might include things like DFCO settings, fuel trim settings, fan settings, and secondary type functions.

But, things like the timing tables, the VE table, the trans pressures/settings/DTCs, etc. all need to be migrated. Download the 2002 OS version I uploaded above and compare it to a stock '02 A4 tune and you can see everything I migrated over.

If he did, he would notice that you say that all tables need copied from the 2000 to the 2002, but DaddySS and RevGTO say to leave the 2002 table if you haven't changed the 2000 table.

Why do you think unchanged 2000 tables need to be copied to the 2002?

Because an '00 LS1 is not the same as an '02. There are differences between the knock sensor tables, injector tables, airflow tables, spark tables...I'd say more than 75% of the tables are different between those years. All those tables interact together. If you want the car to perform like it did before an OS swap, I suggest copying ALL of the tables.

Most of those tables are different in mine because it is a 6L, 250* cammed, big headed, FAST, etc car. What I don't understand is things like (from your post) D1108 "Desired 1-2 Shift Times" should be copied. But, it is all good. No big deal.

Well, the trans is different too. Desired shift times work with the base pressure and force motor current settings. All of those tables are different. I'm no expert by any means. But if it were my vehicle, I'd want the calibrations for my vehicle's production year.

LOL! Okay, you are working on personal preference and not technical reasons. Take a look at the IFR tables in the 2002 M6 and 2000 M6 and see which one you would prefer. I think I will not blindly copy tables.
