Lincurve help with 2 speed BLDC motor

I started a thread a few days ago about this and realized that I was asking the wrong question for my application. I have a belt driven BLDC motor on my mill with a high and low speed. I have been struggling to set up my Hal file to allow the controller to take care of speeds in the low range.

Originally I was going to use the gearchange comp and realized that possibly Lincurve was better for me. My changeover speed is 1300RPM and I have found some example Hal files that are similar to what I want. My problem is that I have yet to see someone using it to control a variable resister and everyone has used it for PWM. Below is the majority of my Hal file. I'm unsure what I should put below all of the X/Y values of my file but I know that the lines referring to PWM are wrong (they are coppied from the examples I have found) any help would be greatly appreciated.

I basically just started with my spindle in low range at S250 (which actually yielded 85RPM) and moved up from there writing down the actual speed that came back at each requested value. I made 16 total data points which looked like the max for lincurve. I put 2 points right next to each other at 1300 and 1301 so it wouldnt try to interpolate at the transition between low and high gear.

ok so far so good you now need a switch
to get the REAL or the lincurve in to the pwm
like a Mcode
working like
gernerate a BIT signal set by mcode
a AND selects the mux output witch is feeded from the lincurve and the pwm

I actually don't have an encoder on my machine yet. Well, I guess I should say I don't have an encoder that feeds into LinuxCNC. I have a single PPR encoder that gives me spindle speed readout but it's not accurate or useful enough to use for anything inside the control.

The issue im running into is that im not using PWM at all actually. My spindle is run in velocity mode basically like a 4th axis on the machine.

These lines below are the ones giving me an issue and I don't know what I should have them say because I don't know how the syntax of Hal files work

net spindle-raw motion.spindle-out => lincurve.0.in
net spindle-corrected lincurve.0.out => pwmgen.0.in
