That is awesome. Thanks. This could be put into a xdf as a patch to toggle it on the and off.

nomecone

This should be the other motorcycle section.

Are you sure the xdf is made for your version of firmware. They have to match exact location of data offsets.

XDF from who's website? Where is the firmware dump from? The firmware dump you have does look like it's a bad read if the xdf is correct.

File believed to be the Alpina B3 3L ROM dump is now on the project GitHub.

There is also Tools>preferences>general [X]Enable Edit Logging

it makes a log file of all changes made to a BIN file

Reason:
Have parameter/s dependent on a value being updated. Making adjustments and committing the change requires repeatedly opening the parameter because it closes every time the commit button is pressed.

Reason: The description section is small in the edit parameter window. Hard to edit larger descriptions. Suggestion: Would be nice if there was a way to use the big Parameter Comments window to edit the parameter comment/description. Some sort of unlock button or something would be needed as you wou...

Hello. Can I have the answer too? From your question I am going to make the assumption that you do not known what TunerPro is as a tool. TunerPro is used to create definition files for ECU firmware files and then view the data and modify it. There is very little specific support for specific platfo...

Updated vin2hex sheet to a sane conversion. The other worked but was using a wild method that I found. Understanding the binary conversion is much better.

I'm very new to 402 so have no clue how it works. ( will read-up about axis ) Thank you for the help nomecone! I need some time to check this out and do some testing. ( will try this weekend ) I will probably come up with a lot of questions, how you will keep helping me with the 402 journey? Thanks...

Step 2 continued Here at FA44 this first a self address so you know you are in the right place. 44 FA -> FA 44 . Next is the location of each table written in little endian, last byte first.

You should view with 16 bytes in a row. The data is there and it is same tables of data. You should 1 offset the file so the index of tables table locations are correct. 2 used the index of table information to know where every table begins 3 If you do not already know, learn the Motronic axis label...

Interesting read. Googles translation works pretty well. I like the better explanation of the vin in hex code. I may try the software to get info from ROM and see if it uncovers anything. I'd rather it show the location, original hex, and then the resolved value. Then it's a complete translation too...

The same/similar maps called lambda from soft 7098 are in a different location in 8599 software

see That Hurxkens and adhamkhe have the same map locations and the data is completely different I think there is a version of BIN and version of XDF mismatch somewhere. Internal location markers in the ROM indicate the ROMs should start offset to x8000. I do not think any of the public 402 bins/xdfs...

I played with making a patch in TP to see what it was like. Bit of a hassle but can be made. I used the MAF calibration as my test subject. First thing I found out was the patch appears to be limited to 256 bytes. MAF cal is 512 so it take multiple entries. I am using the 540(800)/EuroM3(806) MAF ca...

Correct answer. I was mislead from the sounds I was hearing.

Color me surprised. NO PRIMING is the correct answer. Something else is running for ~1 second at key on and clicking off. Multimeter only showed power to pump when cranking. Not on key 1 or 2 positions while car is off. I did not start the car as I had the power disconnected from the pump to easily ...

There is some undo ctrl+z functionality in the editor windows. It is best to keep your own bin file versions saves so you can restore if needed. TunerPro is an editor, I do not think version control is in its scope. Github is one option for keeping versions of bins with the same name. It can keep tr...

I finally came back to this and, actually tried editing an axis for load. I have only been able to edit when using raw hex properly. Putting in an updated converted value does not evaluate properly. I wonder if there is a method other than direct hex edit that can work for Bosch style axis in TunerP...

nomecone

My posts are a bit rhetorical at this point. But I'm still trying to figure things out on how I want to display them in the XDF. Currently, all the tables that I have labeled use the hex offset of the data, not the beginning of the axis information. The index of tables in the ROM data uses the begin...

I have been trying to resolve the injector constant into its parts. It much be made up of a value representing the injector size, unit conversion factors, number of cylinders, stoichiometric ratio(possible the value stored in the ROM is used), and revolutions per cycle.

nomecone

What method do you use for scaling. Did you scale the load axis or did you scale/compress the data that has a load axis to the lower load side?

I'm actively working on defining all the things that get adjusted for injector size changes but what I'm doing is a slow process.

I'll put multi meter on and check this weekend

Interesting thx. I was wondering how can this happen with only 2 wires to the pump assembly?

Pump powers on when key is in start position. DME does not regulate it to my knowledge. - Updated with corrected info

The m3.1.1 does not exist to my knowledge either.

You would not want to tune MAF calibration data to tune a car.
