Unfortunately, here in the USA, we sometimes get roped into fixing things with Brand H ECU. This is Brand H manufacturer developed DI Rail control on an engine they claim is fully calibrated and ready to go. There is no access to calibrate any of the DI pump control. That oscillation is 125 bar. LOL
This isn’t a bash Brand H post, its a thank you post. Thank you for developing a product that the end user can actually use!!! Which the bottom of the picture shows.
We saw similar stuff from another manufacturer with a DI solution.
In their software, it appeared to be okay, but when we spliced the pressure sensor signal and logged it at 500 Hz with no filtering, it wasn’t OK.
We knew it should be working better, so we focused on every detail of the direct injection system to have precise control. We also wanted a universal and flexible system that enables users to start new engines by themselves. We are glad our plans were achieved, and you are happy with the product.
