s200 tune upgrade to s300

I am interested in upgrading from my current s200 setup to an s300 unit but I want to keep the tune I currently have for now. To determine if I can take the tune from my s200 to the s300 do I just need a chip burner/reader? Would the order of operations be:
1. pull the prom out of my current s200 equipped ECU
2. put the prom in a reader/burner and download the contents
3. upload the contents into s-manager and see if it opens correctly
4. if it does open, this means I can easily upload this tune to a new s300 unit?

I would like to figure out this compatibility question first since the nearest hondata dealer is 4+hrs away. I want to see if I can just order a new s300 from a dealer and then upload my current tune if I can get it off the prom in my s200. Thanks in advance for any help/guidance.

Information is in the help file. http://www.hondata.com/help/smanager/up ... 3files.htm

First you need to find out if it was tuned with Romeditor 3 or Rometidor 4.

So the link you provided makes it sound like upgrading a v3 file should be no problem but it does not address v4 files? Is the only way to figure out if the tune was done in re3 or re4 is to try and access the information on the prom using a burner/reader?

The info in the link is minimal so any elaboration/extra commentary is greatly appreciated.

You should contact your tuner to find out what they tuned it with. If it was tuned with RE4 then only your dealer will be able to assist you with upgrading the file.

My tuner past away about one year ago. The car was tuned about 5 years ago and I am pretty sure he was using re3 at the time. If this is the case should I be able to access the information on the prom using a burner and try loading it into s-manager?

I am taking advantage of the s200 to s300 upgrade promotion. I was wondering if any one can comment on the turn around time once the ecu arrives at hondata? The form says 2-3 days but I was wondering how accurate this is. I am also curious about what hondata does as far as testing the ecu before shipping out to customers. Thanks for any info.
