Our B58 v1.0 base map (available on the website) is fairly conservative when it comes to high-pressure target and start of injection. Since it was tuned at 0.4 bar, you may notice injector duty cycle maxing out at higher boost levels.

We’ve prepared a B58 v2.0 base map with an updated high-pressure target, revised injection parameters, and improved high-pressure pump control.

This base map is available in the recently published [New EMU PRO software version 261.0.1 beta](https://community.ecumaster.com/t/new-emu-pro-software-version-261-0-1-beta/6165), under the “Load base map” feature.

You can use it offline to review the values in the v2.0 base map, or load it directly to your ECU. That said, as @mkuklis_ECUMASTER noted, base maps are only a starting point and still require careful tuning.
