I now get 45MPH with the 7.5hp moter I just replaced from the 5hp moter that came with the E-4. I drive 15 to 20mph 99% of the time but it’s nice to know I got the stuff under the hood if need be.:roll:

Nice! Have you noticed a big difference in range?

Not any difference at this time. This is because the Min Field Current adjustments only kicks in at 25mph +. Because I only use higher speeds to get out of the way of faster moving traffic I found no difference. However with the extra current to the moter as you already know ,there will be a lost in range if I drive hot all the time. I’ll measure the difference with hot driving and post it up soon.

wow Blackhorse… I want to do that… just found the law change in CO that allows LSV/NEV’s to travel on streets limited at 40mph… what fun it would be to stay up with traffic… what size tries do you have on your car? with 185/65/R14’s and the 5hp motor I can get to 28mph… am trying to get the program from Marlon to get into my controller and make some changes without going to the bigger motor…
