Firstly you should set up your BASIC settings pas 1-9 incrementally say from 10-100% CURRENT and SPEED LIMITS.
You can then set your throttle at any of the 1-9 pas settings you set up on the BASIC tab, so if *)% is on pas 8 then set throttle to pas 8.
I will attach my maps so you can get some ideas, but BEWARE, there are differences to BBS01 BBS02 BBS02B and BBS1000HD motor controllers, they all have different MOSFETS in them and can be blown/overloaded, so be careful what you change, I run a BBS02B 350W with 48V x 10.5AH battery and a BBS02B 750w with 48v x 17.5AH battery, you will notice on my 750W model (Program attached) that whilst it has 25AMP controller I have limits set way below for safety. (on my other 350w motor with 10.5ah battery my current limits are a step down again.
As a matter of interest, I have no set limits in any BASIC pas, and my THROTTLE at pas 5 (50% current ) is ample to get me up most hills in my neck of the woods

IF you are unsure what you are doing I suggest you download PENOFS own programmer which has some SET LIMITS you cant override
