Blitz SBC reading wrong boost

Just installed Blitz SBC boost controller from crashed car into my new 2JZ-GTE (stock motor). The boost controller sat around doing nothing for about 6 months.

 

Reading should be 0.8 bar.

 

Blitz SBC reports 1.48 bar.

 

Removed solenoid completely to eliminate.

 

Blitz SBC STILL reports 1.48 bar.

 

Remove Blitz SBC vacumn hose and put in it's place a manual boost gauge on hose. Boost is 0.8/0.9 bar as it should be.

 

The SBC controller itself seems to light up and work etc.

 

Any clues to the huge boost difference? Obviously the Blitz SBC is not measuring correctly - there is no fuel cut (which occurs at 1.1), manual gauge says 0.8 and my air/fuel meter is a-OK.

 

Is there some hard-reset I need to perform on the Blitz SBC?

How do I access the main menu/reset? I typically just have options/modes for OFF, various boost levels e.g. 30 / 40 / 50 / 60, peak boost and warning boost level...

 

Remember it's this boost controller I have :

Just as a side point, is there any possibility there could be a problem with the vacumn hose? e.g.if it's kinked or a hole in it etc.
