🚗💨 Diesel engine fuel timing calculations

edc15-eoi

This is a simple tool I created to be able to easily tell the precise time of End of Injection event in PD TDI engines.

Getting started

1. Download & install the latest version of Python from: https://www.python.org/downloads/
2. Download this repository as a zip and open a console window in that directory
3. Run pip install -r requirements.txt to install the dependencies
4. Run py eoi.py to test if the program's working

Usage

Run the following commands to get started quickly:

git clone https://github.com/krook1024/edc15-eoi.git
cd edc15-eoi
python -m pip install -r requirements.txt
py ./eoi.p -h

Listing available codeblocks

Let's imagine we have a file called current.bin, in that case we can run

py eoi.py -f current.bin -l

to list the avaiable codeblocks. The output will look something like this:

 Available codeblocks in current.bin
╭────────────────┬─────────┬─────────┬───────────────┬────────────────╮
│   CodeBlock ID │ Start   │ End     │ ID location   │ Gearbox type   │
├────────────────┼─────────┼─────────┼───────────────┼────────────────┤
│              2 │ 0x717ee │ 0x817ed │ 0x77a50       │ Manual         │
╰────────────────┴─────────┴─────────┴───────────────┴────────────────╯

Showing actual duration & EOI

After finding out the codeblock ID, we can go ahead and run the program like this:

py eoi.py -f current.bin -c 2 

and it will show all the necessary maps and calculations.

If you want to also show the tables in a graphical view, you can use

py eoi.py -f current.bin -c 2 -p

Notes

• You can run py eoi.p -h to print the documentation of each argument.
• The order of the arguments don't matter, as long as all required arguments are set.

edc15-eoi's Issues

Working only on specific EDC15P bins

I was able to load only a specific set of BINs
Apart from CURRENT.bin (AJM bundled in repo) it works on original Golf IV AJM BIN (EDC15P+) but everything else ended up with error below.

Traceback (most recent call last):
File "/home/noveria/edc15-eoi/./eoi.py", line 3, in
from maps import soi, selector, durations
File "/home/noveria/edc15-eoi/maps.py", line 5, in
soi = Map(
File "/home/noveria/edc15-eoi/edcmap.py", line 58, in init
self.load()
File "/home/noveria/edc15-eoi/edcmap.py", line 87, in load
line.append(self.fun(unp(self.file.read(2))))
File "/home/noveria/edc15-eoi/edcmap.py", line 11, in unp
return unpack("<h", byte)[0]
struct.error: unpack requires a buffer of 2 bytes

I am attaching some of the BINs I was using for testing
