hey guys! hope you are all having a good day, anyway on my topic. i bought a tfv4 and i tried using it on my surric x but it doesnt seem to fire. tried it on my other mod (stingray jdtech) and it works fine. i tried adjusting the pins and see if they touch and they do. i dont know what the problem is and i was hopin for some help. I'm using a tfv4 with tri-coil at .15ohms max 120w and my surricx has a limit of .1ohms resistance and a 200w output. tried my box mod and works fine on my douge rda with a dual coil that is at .12ohms. please help
