I got the 58V put in and i like it. It does seem to be a little more responsive. Starts strong to. My old ficm was weak but running and always started with no problems. If someone wants it for a $100 bucks just pm. me.

Is your old FICM 7-pin or 4-pin?

my old one is a 7 pin. It would hold the 48v through cranking and then drop when first started but when the truck came up to temp it would show 48v again. I did try the solder trick but didnt fix it. Maybe i didnt do a good job or maybe something else is wrong i dont know.:dunno:
