Good news and a nice surprise.

Last Tuesday my car had its electronics diagnosed. Results? Only 2 errors, both old,
both caused by works that we have done before. As the car has electronics in a good state and no errors or potential damages that need to be fixed were found, next step is preparing its engine for dyno. This means some restoration which I will show you after I got all needed things. Below photo of print from diagnostic service:

We got errors number 19 (wrong signal of engine RPMs) and 145 (wrong signal from immobiliser). And that's it :D Everything is working fine, I'm going to collect all things I need and make a video of basic actions you should take if you want to make your engine running better! ;) So stay tuned for more. See you!
