Ecu pinout is available in the FR. you can Google "Simos 18 FR" to find it.
Full car wiring diagrams are all available for download from VW, you just have to pay for access. It costs $30 for 24hr iirc. You can download as many docs as you want in that timeframe.
If you have an R/S3, then you could at least use opensource logging to see the ecus MODELED shaft speed. Which won't even be remotely accurate if you've switched turbos.
Haven't had a chance to see if we can wire one in or not.
Yeah, in California they recently started checking for tunes by looking at something called a CVN.
Open source - I'm one of the devs and we don't do CVN 'correction' so you wouldn't pass
UM isn't doing any CVN 'correcting' so you wouldn't pass with a UM tune
APR won't do CVN 'correcting'...
Is the forge pneumatic?
That 100% has the potential to cause massive issues with the way the ecu operates to control airflow.
The throttle position has no direct correlation to the pedal. When you let off the pedal, you're asking the ecu to make less power. Sometimes that means keeping the...
It wasn't an enormous rant. It was a detailed explanation for the way the ecu actually works to meter fuel and control boost.
The ENTIRE issue with the tuning community is that nobody shares any actual information and so people are left just guessing about how things work. It keeps people...
Just to echo what @ZuMBLe has already said:
- The ecu meters fuel based on calculated airmass
- It calculates that airmass based on the flow characteristics of the engine (VE).
- The only sensors it has to do that are the air pressure (PUT, MAP, and ambient) and air temp. I.e. the airmass is...
@aaronc7 I THINK 425C is 18.2, yeah?
I had used Brian's unlocker to unlock a 425C on the bench, but we would have to build a new unlocked CBOOT to flash via obd going forward.
@paan It's nontrivial to get that hardware set up with our software (but it could be done). I can try and take a...
The ability to pull a file off the ecu via obd2 is completely disabled in code - so it only supports what's called "virtual read". Even commercial tools will read the box code from the ecu and then download the file from their own central repository.
You can flash over tuned files, depending on...
