Memory block/log comparison

So I've discovered how to edit tire size in my f250 via the ABS module using forscan canned options. Now I need to compare the saved FORSCAN log with the ASBUILT so I can locate the memory block associated with tires size so I can enter in my correct size and calibrate this speedo exactly finally. C...

Re: Setting arbitrary tire sizes for speedometer calibration

I understand how that works and used your formulas to calculate my own revs and circumference. But if I go in to edit ASBUILT I have nothing listed, only a series of three boxes at the top that appear to be to search or call up specific memory block locations

Re: Setting arbitrary tire sizes for speedometer calibration

You are correct, I am editing the canned FORSCAN settings for the ABS module. It did however change the speedometer and odometer calibration. Is there any documentation that contains year and model specific memory block locations for ASBUILT editing so I will know where to look?

Re: Setting arbitrary tire sizes for speedometer calibration

I've located it I'm the abs module and there is a list of different sizes of tires in there and one choice named other. However my size isn't in there nor can I figure out how to manually enter the size and revs for my tires.

Re: Setting arbitrary tire sizes for speedometer calibration

Would you happen to know the location code in the module for 2001 year models?
