'''Any or a combination of these functions should provide proper off starting line response''' - DB --------------------------------------------------- How I can reduce power on start only ?? in all of this option car always running on retard ignition on 1 or 2 gear or reduced boost or when im active launch time vs ignition retard i have retard ignition on each gear. Im need some special conditions for launch setup some like no2 conditions , and strategy for holding rpm by specified time 0,1 sec on 4100 rpm 0,2 sec on 4300 rpm 0,3 sec on 4500 rpm 0,4 sec on 4900 rpm etc... In wheelspeed firmware '''by-speed launch-RPM limit is more reasonable''' and more commonly applied. Using by time is also possible: * definitely in the PS2 firmware. * I think even in wheelspeed firmware, anyttrim on launchtime (+ 50% tps) and trim launch rpm easy * see: http://vems.hu/vt/help/v3/v3_anytrim_control.html for more details '''Trigger Problem With hall sensor''' ------------------------------------- i use this sensor and trigger wheel sensor: https://www.autoatu.ro/uploads/tdimages/159/01590175803255.jpg trigger wheel http://autodbase.ru/433_2016_2q_deadlock38/images/162/01620265803255.jpg and problem is with trigger errors i change in vems SJ2 closed, SJ6 open R30 pullup - install 4k7 resistor, and 2701 still problem my config file http://www.vems.hu/files/Audi%20URS4%20Kryinu/v3.3_u006060-2017.07.18-08.33.21%20do%20wysylki.vemscfg trigger log 4k7 resistor http://www.vems.hu/files/Audi%20URS4%20Kryinu/v3.3_u006060-2017-07-17-18.19.28%20with4k7%20resistor.triggerlog trigger log 2701 resistor http://www.vems.hu/files/Audi%20URS4%20Kryinu/v3.3_u006060-2017-07-17-15.22.20%20with%202701%20resistor%20.triggerlog Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
