Here is a little bit of work I've done that may be of use to someone. The first bin (748mk2) uses the .xdf from the speedzilla site and is just the basic 748 map with the 2nd cylinder offsets from the 996 copied in. It worked rather well for a first attempt and I've used it all summer. Makes the bike a bit more grunty and nicer to ride. The second one is the previous copied into the UM222 bin with a tweek about 2500rpm to remove a bit of unpleasantness. The bike runs REALLY nice with this map, a lot more responsive. The bike is a standard '95' bike with ST4 bellmouths, over-bellmouth filter and an exhaust that has had the welds cleaned inside. The silencer appears standard, untouched Ducati but is straight through, everything 45mm. http://www.ducati.ms/forums/56-superbikes/279737-designing-ultimate-1-6m-chip-33.html#post3246385 Serious Black You use a 32k file on a 64k eprom by burning the file from 8000 to FFFF. the ecu looks at the top 32k, which is either 0000 to 7FFF on a 32k (256)or 8000 to FFFF on a 64k (512). you should be able to set the start and finish address in the eprom burner software. or you can burn a 32k file on a 64k eprom twice, once from 0000 to 7FFF and again from 8000 to FFFF. that way it has to get the info. you can make a 64k file into a 32k file using wayne orwigs software - it has a function for that - or by burning a 64k file on a 512 and then reading the top half (8000 to FFFF) of that eprom to a file that will then be 32k. In tuner pro rt, open tools, hardware, moates prom read/write utility, pick 27SF512 chip. For TDW's or other 64k bin, start address is 000000, end is 00FFFF. Load bin file to buffer, erase chip, blank check, program chip, verify chip with buffer.
