Summary of change:
'''FIAT Uno 1.3 Turbo''' *4 cyl, 1.3 Liter *Vems V3.3 *wastedsapark coil *K04 turbocharger *high impedance injectors, 380ccm * '''12-1''' HALL primary trigger on the crank, with GT101 sensor, no secondary trigger ** '''in 1.1.x firmware the "Special N-1" must be enabled for N-1 missing tooth wheels''' *equipped with VEMS Bigharness *30V flyback diode is equipped for smooth idle *1.1.18 firmware *4 bar MAP sensor Solved problem: when "N-1" was not set, ignition was missing out in certain loadsites (RPM and ignition advance combination). The configuration files with bad primary_trigger setting, as "N-1" is not enabled. http://www.vems.hu/files/Fero/UNO/config.txt http://www.vems.hu/files/Fero/UNO/tables.txt http://www.vems.hu/files/Fero/UNO/datalog200706211820.xls * boost_channel=68 ??? ** corrected * supply voltage of ignition coil ? (maybe you need thicker wires or a 25V cap ?) * Can you strobe the engine ? ** Strobed the engine, the spark is not continous (with the bad N-2 setting, when N-1 was disabled) * '''primary_trigger=11 is needed for N-1''' (assuming missing tooth and rising edge) ** '''primary_trigger=01 is only good for N-2 !!! set bit4=1, because bit4=0 means N-2 that is bad for this engine''' * calibrate tps, maybe some cut spark idle control enabled? *TPS is calibrated good *Tried a thicker wire to the ignition coil. ---- '''Triggerlog''' http://www.vems.hu/files/Fero/UNO/triggerlog.zip Triggerlog only works properly during cranking (because of the baudrate of serial connection). With this 12-1 it works even up to idle, but definitely not above 2000 RPM ---- I've uploaded 1.0.73 firmware from the Megatune1.0.73final pack. 1.1.18 firmware definitely requires some more settings, like reftooth, toothwidth and the "N-1" Here are my 1.0.73 config files, after some short tuning session: http://www.vems.hu/files/Fero/UNO/config_1.0.73/config.txt http://www.vems.hu/files/Fero/UNO/config_1.0.73/tables.txt
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
