Old Firmware request, ASAP please 29G

[Toma]

Hey, got an old system here, connects with Tuner studio, says says signature is msns-extra 029f******** and firmware found is megasquirtnspark extra 029g****

I need this definition ASAP, as we are sitting on the engine dyno, and I really do not want to upgrade firmware until I can see the tunes/configurations in the boxes.

Help please ;)

Thanks
