Tried to look at PCIIIr timing maps after downloading them, jibberish! What I need is the timing change at various throttle positions and RPM's to construct a timing map for my Yosh box. Yosh box came with 6 fuel maps but no timing maps. I made one timing map with 2.5 degrees advance across the board but doubt that is ideal. Help!

Well, I lucked out. I went to Dynojets site and downloaded their software, then came back here and downloaded the available PCIIIr maps to the same folder. Opened the Dynojet software, hit the load map button and yureeka! The map from Dynojet for the 12 with a Yosh duplex and K&N has no timing map. The Kinney zx12r map has no timing map. The Atom Racing timing map varies quite a bit. Changes a lot from 5% throttle position starting at 2K RPM and tapers to 60%, 80% and 100% throttle position alterations only @10K. 80% and 100% @ 10.5K-11K, then only 100% @11.5K RPM. Hanks timing map appears nearlly identical to Atom Racings. Muzzy's race map is as follows: from 0%-100% throttle position, at 2K-5.5K RPM 3 degrees advance, 6K-7K RPM 4 degrees advance, 7.5K-10K RPM 5 degrees advance, 10.5K RPM 4 degrees advance across the board and finally at 11K RPM 2 degrees advance across the board. No advance above 11K RPM. Does anyone know if Muzzy's map was for a stock discplacement 12? Finally, all the fuel maps vary but seem to follow the same general pattern of changes up and down at the same positions, just different percentages.

Instructions kind of suck with the Yosh box, buuttt---each individual fuel map is 3 maps in one! Each map includes a baseline (ideal) map for the Yosh system they were testing and a +5% map and a -5% map. You can easily program which of the 3 maps is the default map. Soo---with the 3-way switch option 9 total maps are available. Only 3 map choices at a time, but with a computer handy the defaults can be quickly changed. Something like this, switch position one; map A or A+5% or A-5%, switch position two; map B or B+5% or B-5% and so on. Or, the switch could be used for one map and its +/- counterparts. Say switch position one; map A-5% for thrifty riding, switch position two; map A for racing, switch position three; map A+5% racing plus nitrous. The unit comes with 6 maps, one, a zero map doesn't count. That leaves 5 individual maps, each one with its +5% and -5% counterpart. Since no timing maps are shipped with the unit I don't know yet for sure if the same benefit exits. I think that it does because the software lists fuel map 1, timing map 1, fuel map 2, timing map 2 etc. To program the 3-way switch requires yet another button. To test this theory I printed out all 6 maps, each fuel map, baseline and +/- included a timing map! Now I guess I've just got to plug in some figures on the timing maps and go with them.
