Wiki-spamming is not tolerated, will be removed, so it does NOT even show up in history. Spammers go away now. Visit Preferences to set your user name Summary of change: '''Issue''' IGN output behavior changes with RPM and # of cylinders. * Firmware 1.0.23, Megatune r27 and r30 all show same results '''History''' I found this issue when attempting to functional check a unit prior to configuration. Initial reports suggested that it was a bad trigger signal (benchtop generation). Resolved this problem and '''now can generate a proper 60-2 wheel VAG style without any wheel count errors.''' '''Description of issues''' * Given: [MembersPage/GrmRacer/TurboSetup/TurboConfig Config] firmware, and tables '''Problem with precompiled firmware''' Firmware version 1.0.23 as downloaded from filethingie * no recompilation done * configs & Table changed using MegaTune (r30) only * pretending to be end user trying to get board setup * I also don't want to go thru the toolchain setup to do it. ---------------- Problem is that the number of outputs driven changes when a factor of RPM and # of clyns and #of IGN outputs selected '''Original configuration to find problem''' Basic description is the Ingnition outputs were set in ''Ignition Settings'' Outputs to use in h[2] set to [7..0] *Ingnition ouputs set to **0 Drive00 **1 Drive01 **2 Drive02 **3 Drive03 **4 Drive04 **5 Drive05 **6 Drive06 **7 Drive07 ''Yes I know this is not valid for a wasted spark BUT, it produces bad output. '' **above 41Hz(~2500rpm) with an 8 clyn setup **above 29Hz(~1650RPM) with a 4 clyn setup Symptom above these values all IGN outputs that are set are triggered else only 2 outputs are triggered. ''if Ignition Settings '' *outputs to use in h[2] is set to [1..0] symptom goes away. '' if Ignition Settings '' *outputs to use in h[2] is set to [2..0] three outputs trigger above 41Hz(4clyn) '' if Ignition Settings '' *outputs to use in h[2] is set to [3..0] four outputs trigger above 41Hz(4clyn) * * '' if Ignition Settings '' *outputs to use in h[2] is set to [7..0] 8 outputs trigger above 41Hz(4clyn) ----------------- Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
