S/C calibration ID numbers

[Philby]

Been driving the truck now for 10+ years with the TRD S/C with no issues....just turn the key and drive. When I reflashed the ecu for the s/c all those years ago the calibration ID number was 3YWG0200. Recently I found on the web that there has been 2 further releases.... 3YWG1900 and 3YWG2800 since the install.
Any clues as to what has been added/changed in the software?

Very interesting question. I'd also like to know.

Could be related to the air injection on the newer trucks and or the reflash for the accelerator/brake override...can't say for sure. @o0opackersfano0o and ideas? You're the yota tech...

They are not updated calibrations, they are different calibrations Your original ecu calibration would dictate which trd s/c calibration was used.

They are calibrations for other problems. Like the spark knock one. And I think for another code. I can figure out what they are Monday.

How'd you go.. any luck comparing the calibrations to see what was changed?
