My Programming PSU

harkes · 05-05-2024, 04:30 AM

This has been done many times before so just to share another success story and weekend project

DSP-600PB PSU. I used a 10k Ohm potentiometer between Pin 7 and 9 to achieve 13v output. ISTA+ requires 12.55v.
For my F20 a single PSU is keeping up just fine

The work will not win any beauty contest but it works; and awesome how the handle doubles perfectly as a clamp holder

Nice, could you make a diagram for the connections you made?

The best voltage for flashing is from 13.8-14.4

ISTA+ is only asking for >12.55 so hope I'll be OK. If I can even make it work with ISTA+...

Ista said min is 12.55 before start to warn you but normally 13.8 is optimal so I will suggest you to make 14V
