(adsbygoogle = window.adsbygoogle || []).push({}); Hi so basically i'm trying to change the accuracy of the MTAR -*0x26FFB99. It doesn't set unless you call it with the byte -*0x09. That will only make the accuracy 100%. I want to use a numericupdown to choice the accuracy amount but I have no clue how to call it. Can someone please help? Any help at all is appreciated!

Are you sure of the data size? You could just be setting the most significant byte of a short or integer which would cause drastic change between 8 and 9 for example, because in a short, that is 8*64 (pretty sure, really tired right now so might be off). Try manipulating the bytes to the right of it in memory. You might get some different results.
