Like the title says - I have a newly built half-bridge and I need a base map to get it started. Thought I saved all of BDC's base maps from back in the day but that was several computers ago and they're no longer online.

Anyhow if someone would be able to provide a map that would allow me to start and break-in a half-bridge with 850/1600 injectors and APEXi 3bar MAP sensor I'd be quite grateful.

Starting mean running at idle up to no higher than about 2000 rpm max under vacuum.
No Boost. THUS IT CAN NOT BLOW THE ENGINE!
Any stock map with proper injector setup will work.

But to improve startup and smoother idling before using the commander to tune the idle on a large port and large overlap intake engine, timing and cold start retard need changing.

Settings 4, IGN vs Water T Cool, set the retard for 60C to 0, no retard. All modified engines should do this. For the idle area from N1-N5 and P1-P5 set IGL to 12 and IGT to 19. If you are using idle speed control, only do the retard step as the other will not function. No idle speed control works better for large ports as it allows 100% control of the idle.
Use hotter leading plugs for startup on a new engine to reduce fouling while you do initial idle tune.
Open the the throttle screw about 1/2 turn more..

Have a flat head screw driver handy with the commander on Setting IGL/IGT/INJ to quickly make changes after startup.
************************************************** ************************
When the PFC is set to control the 3 idles with values set over 0 rpms, the PFC runs a hidden idle timing map witch is extremely terrible for large port motors. To override this, all three speeds need to be set at 0. This turns off idle control over air flow. You should also turn off O2 feedback, always needed when the air pump is removed. But this makes you responsible for idle control air flow, fuel flow, and timing.
Just like cars were before FI and ECU!
