When you enter any changes in the Custom Options menu, make sure you hit the <Enter> button to record them. Then, when you're all finished and want to program the PCM, select "Done" in the menu, turn the key off then on again.

At this time, it creates or updates the "Previous Options" file, which it stores in addition to programming your PCM.

Now, suppose you want to reprogram something. You have two choices. If you DO NOT select "Load Previous Settings" as your first choice in the Custom Options menu, you will see the "default" settings for everything! So your shift firmness will be 0, your speed limiter will be at 99, your tire size may very well be some bogus value and so on. You can manually reenter all the values you want as JWBFX4 suggested.

OR - you can select Load Previous Settings as the first step. If you do, you should see the +5 for shift firmness that you set the last time. If you raised your max speed to say 110, you should find that value in that menu selection now. There's one value that doesn't seem to quite "hold", and that is tire size. I set mine to 2481 and when I load previous settings I always find it is at 2484. Bill explained once that the unit sort of "rounds" tire size in mm to a value it can store in binary (possibly converted to inches?)

The "Load Previous Settings" brings back the previous set of values you entered in the Custom Options menu during the most recent programming session. It is a single file and is not specific to any level. If you "Load Previous Settings" partway through the Custom Options process, it will reset anything you've just changed to the values you set in your previous tune. It's designed to simplify your setting of custom options, so you don't have to do them ALL over again when changing from Level to Level (which is why you want to Load Previous Settings first).

Bill does adjust things like shift speeds or RPMs, shift pressure, timing, etc when he writes your custom tunes. I suggest you try his values out at first. (They will be the "zero" points in some of the options - in others, like WOT shift RPM, you'll see a number like 4975). But, you CAN change these after you've tried them if you decide you want to.

I hope I've helped - I agree, it's all very confusing and I'm not sure I could write the manual any better than it is.

soooo... if I get to where it asks me if I want to create custom options, if i say "yes" and hit enter, every parameter that I previously set returns to 0 or default?
