help finding firmware and adjust PID

[thoxbui]

Hi there
I have an acrylic i3 printer bought last year.
According to Repetier Host, the firm ware is:

< 3:02:44 AM: FIRMWARE_NAME:Marlin V1; Sprinter/grbl mashup for gen6 FIRMWARE_URL:http://www.mendel-parts.com PROTOCOL_VERSION:1.0 MACHINE_TYPE:GEEETech I3B EXTRUDER_COUNT:1 UUID:00000000-0000-0000-0000-000000000000


I'm running into a little problem, trying to put in new PID values. I auto tuned, and changed the configuration.h file to the new values.
But uploading the changes doesn't seem to do anything. The values for PID reverts back to default.

Is there a newer version of the firmware that I should/can use?

Thanks
