In legatura cu asa zisele "harti" , RobyS , uite ce raspuns am primit mai demult de la un seller de power box-uri (www.italianspeed.it) Hello, Thank you for your communication, ok, I understand, everything. So, honestly, our box, especially on particular car,for examble 177 engine, is certainly one of the best. Almost all sellers fail on this engine, and even us in the past. But now, we have created advanced programs, which are able to achieve the potential of that engine, although not much. Generally, on that engine, we obtain a maximum of 25 horses. Our box, did not have display, but has switches to select 4 maps, divided in this way: RACE = MAXIMUM PERFORMANCE LINEAR AT ALL SPEEDS SPORT = MAXIMUM PERFORMANCE MAINLY AT LOW AND MEDIUM ENGINE RPM FAST = MAXIMUM PERFORMANCE IN START - MEDIUM POWER AT ALL SPEEDS SPEED = INCREASE THE PERFORMANCE ESPECIALLY AT HIGH SPEED In addition to 4 maps, there is a power regulator, classic. Although there is present, the power regulator, the box is digital. If the power regulator, is increased excessively,may enter limp mode, but decreasing it, limp mode goes away. For further information or clarification, consider me at your disposal, cordially Mirco Italianspeed Team
