Changing the mapping in tuner pro

Hello, I want to make changes to my map and I do not understand the unit used in tuner pro. For example, in this picture, for the maximum speed for the gear shift in automatic mode, I 203. What is this unit: decimal, octal?

You'll find a lot of the values have not been scaled to actual values and appear in raw decimal.

why can one change the shifting rpm in the dme?

does the dme tell egs when to shift? i thought egs would work independently and decide when to shift.

Its a scalled value from 0 to 255. However you need a prom chip like the Ostrich 2.0 to have any hoppe of using tuner pro to tune anything. This will not work on an e46 - at least not with the stock computer.

Raw decimal for a single byte is 0-255. No scaling applied.

You can indeed tune it as long as you fix the checksums and load the changed tune in with a reflash program like "Galletto". The Ostrich and Ostrich 2 won't work for these MS43 DMEs as it doesn't support emulating the chip the MS43 uses.

So? its possible to raise shift rpm in manual mode to higher values then revv limiter from the engine?

Daniel, you know I can't go into details about tuning these currently.

Ok but how could quickly convert all these values ​​for the corresponding true values​​?. Has he a plugin or software that can process and convert this information? I also want to ask a question about the ignition advance. I have a scale of "null" to 15 to 300 ..., what and how it matches could have the unit in degrees?

The scaling needs to be defined in the definition file you're using. Whoever made the definition file doesn't actually know the scaling for it or the ins and outs of tuning these boxes.

Those axis are clearly not real-world values.

Hello, I bought a KWP2000 + to read my original map and I have the following numbers when reading the ECU. 7511570 0468 111430533703. What is my software? Is compatible with the XDF 430055? If it is not compatible, or can I found the right XDF?
