Hi,
I am new here. I am a retired mechanical engineer. Always wanted to dabble more on the programming side of cars. Finally have time to do it.

I have already read the BIN off the car but can't seem to find the proper XDF file to make sense off the data.

Here is the ecu data for my car.
HW: XW1FBB
SW: CRAIBMA.hex

I tried the crai8 xdf but my BIN starts with data immediately where as the sample bins provided have a long list of lines with only y's before parameter data.

Anyone can help me with the proper XDF?

Thanks in advance 👍

This is exciting stuff 😁

You have to use crai8 and the FLC2 file.

Simply copy over your pats code and vin from your read out and then you can delete it as its useless.

So I overwrite the ecu with the new bin file?

What are the differences between my original bin and the FLC2 file?

no, qh can't overwrite the ecu but yeah you don't need the stocker

nothing, all the same

I am not using moates, I am using a Kess V2 to read and write to the ecu and a raspberry Pi data logger.

your really limiting yourself then, the pi isnt going to be able to log well enough to log what should be logged to get anything meaningful for tuning.

Not being able to tune realtime using kess is going to severely hinder making changes and getting her exactly how you want.

far better off upgrading to a QH

Thanks for the advice.

I couldn't find a QH.

For sure I would have preferred to have an ability to tune realtime if I could.

The pi data logger is logging everything from an elm 327 and a wideband sensor.

What else should I be logging?

Thanks for the support 👍

You couldn't have looked too hard... viewtopic.php?t=995

ELM327 uses the obd2. Thats 60 bytes at 10 frames per second. You also can't log any ecu correction errors that way either.
QH is 256 bytes 1000 frames per second. It has to be slowed down because It logs faster than the cylinders fire. It also logs all the ecu corrections automatically.

Your basically logging with very limited 1980s technology. There's been 40 years of advancement your missing out on.
THERES NO COMPARISON.

Thanks for the input

Really appreciate and happy to know you sell the QH.

I am almost done developing the pi data logger with my son. A young future engineer like his Dad 😁. So this has been a project to get my son a bit more into cars. He spends too much time on his room coding and playing with his pi's and Arduinos.

If the pi isn't going to cut it. I will reach out to get a QH

Thanks 👍
