its doing what it can with the parameters you set when you que'd it in... you either have a lowish ohm build and the software is accepting it, but not really doing its job properly.... the software takes into account the resistance of nickel wire to be a standard, so it takes that info and when you set the temp it reads the resistance and then varies the voltage to the coil in an attempt to match what resistance the coil should be at at a specific voltage
kinda like having software in your car for cruise control... the software sez your engine should be at 2000 rpm in 5th gear to be going 70mph. If you force the gear to be in 4th, the engine will rev up higher to make the car go 70mph. By using a higher ohm per inch wire ( instead of Ni orTi) the chip will make the system work differently.... you will still go 70, but your gas mileage will be terrible
