Summary of change:
Car Nissan CA18DET ATM fiddeling with why the car wont start, seems like i got the triggering right and the ignition and injectors set right in the options.. But all that happens while cranking is random misfires.. '''ECU serialnr=3822''' (orderid=7469) Was "sectrig for 360 pulse nissan trigger" requested in the order comment ? (to lower the sectrig filtering capacitor, as the 360 pulse nissantrigger has 30 times shorter pulses than normal sectrig pulses). Although this is more relevant at high-RPM, let's see clearly. '''ECU 3822 was ordered as''' * primary_trigger: '''EC36/27 VR''' ** must be changed to HALL (1 jumper disable, 1 jumper enable, stronger pullup eg 4k7 instead, or on top of 18k) See GenBoard/Manual/InputTriggerHardWare *** Allready moved jumper from SJ6 -> SJ2 .. But havent replaced the pullup. Is it R30 on this [http://www.vems.hu/files/genboardv3/images/v3.2/v3.2_top_trigg_jumpers.jpg picture] that needs to be 4k7 ? * secondary_trigger: HALL ** Ordered without mentioning 360 pulse nissan trigger, so normal internal capacitor on sectrig: should be replaced to max 1nF. ***This is the c103 right ? I'm using the stock CAS trigger * primary trigger 4 pulses ** length of windows (when signal is high) ? ** rising or falling edge selected ? * secondary trigger 360 pulses ** longest primary trigger window has N (...how many exactly in your case?) sectrig pulses See InputTrigger/NissanTrigger * notably: "how to measure the length of the longest primary trigger window" part... ** you'll want to detail the results of "Nissan special settings Widest window measurement" in [http://vems.hu/vt/help/v3/v3_secondary_trigger_settings.html VT help] ** that is the '''reading from the hijacked "air correction gauge"''' to find out the "longest window length" (to verify how many sectrig pulses the ECU sees in the longest window) in case of Nissantrigger when temporarily inj+ign disabled (forced into safe mode '''with prohibit_h=0 ''' - in ECU calibrations) *** Im a bit confused about what the "Air correction gauge is" Attaching a Trigger log and a vemscfg file for thoose who might wanna have a look see and help me start the car .. * [http://gratisupload.dk/vis/699990 vemscfg] * [http://gratisupload.dk/vis/699991 Trigger log] --- UPDATE Changed the Base setup -> Secondary Trigger Settings ->Ignore sectrig pulse above @ 1. And the engine starts and idles .. But got some trigger errors above 1500 RPM.. Will the pullup and the 1uf capasitor eliminate this ?
