Hi all i have jusst recently purchased defi Bf boost an control unit.just wondering how do u set the peak boost to wat my car is actually running.its set to 1bar standard.Any ideas let me no thanks mark

 

OK, on the control unit there is a button for "warn set" select this button and the red light flashes on the guage and the needle will point to where ever its set too, then there are forward and backward buttons on the control unit, use these to move the needle to the desired boost point

 

if you mean how do you set the alarm just hit the warning button until the red LED in the guage you want to set flashes the most (if you only have 1 guage this won't apply!) then use the up and down arrow keys to set the limit - simple as that
