Convert 2000 to 01 or 02 system

[DaddySS]

I've been searching because I thought I remembered a write up on converting from a 00 to a 01 or 02 operating system. I know I will have save all the calibrations and move them once converted, but anything else I should know/look out for? How for instance is the VIN number handled for a full reflash?

Just paste your VIN into the VIN field of the Calibration tab (go View->Show Calibration Window).

You'll have to open 2 instances of the TuneTool, one on your '00 tune and the other on your '01/'02 tune;
and you have to copy table-by-table; if any tables are transposed, you can un-transpose it using the scratch table under the Conversions tab (go View->Show Calibration Window).

If you go with '02 OS 12212156, then you will be better positioned for migrating to COS5 if you wish later;

+1 for an '02 OS. Many more custom options should you choose to use them.

You guys are the greatest!!! Thanks for the quick response. So just open up the 2002 and the 2000, do all the copying including VIN, then full reflash? How nervous should I be.....

Go slow, check twice, it's easy if you take your time and do it all in one go (I only managed to mess up the speedo cals so not too bad).

Well the conversion went very well. I started by comparing all current calibrations versus stock - this way I knew which ones to leave stock in the new OS and which ones I might want to change. This is helpful since not all the calibrations are the same - some different, some missing, combined etc. and if they were stock to begin with, you don't need to worry about them for now.

For all the calibrations that were different, I made sure I had at leasta fair understanding of why they were different.

During the comparison, I made note of all the calibrations - this way for the ones that were the same I could just breeze through - and any that were questionable I could compare to the 2002 file.

I left all the fuel and spark cals the same as the current tune, this way I could make sure it was working before any changes are made.

My first two logs showed a dramatic improvement in the KR problem I have been fighting - just 2.2 max in a few cells.

I highly recommend this upgrade to anyone thinking about it!

DaddySS, good job.

Interesting. I have a 2000 SS vert also, except auto. If dealing stock vs stock do you still have to copy and paste the tables? I have my stock tune downloaded. I also have a copy of a 02 coupe auto stock.
Thx,

Yes. There are differences in many tables. Timing, injectors, etc. You need to update all tables. Some will be the same, but many will be different.

So copy from the o2 os table by table to the 00 os? So I will have all the 02 info,parameters, etc. but still 00 OS? New tun file name of course.

Thx for the help
