Visit Preferences to set your user name Summary of change: Audi PnP Standart box '''aan/16082''' no spark. Marius Helmersen Norge Audi S4 AAN. Ecu installed but they have * '''no spark while cranking'''. * They have spark in test mode. * They have stable Rpm reading * They have Stable Rpm tachometer * They have injectors firring while cranking. * It is not in safety mode. * Car runs with PnP BOX AAN 3742 (is box 3742 a jumper wire box or new pcb) * Installed same config as the running box 3742 *Is box 3742 different from box 16082? could be that Ign. coils + is low at cranking and only high at ignition on. Log of cranking the car. http://www.vems.hu/files/MembersPage/PeterJensen/S2_log/v3.3_u016082-2018.07.06-22.16.26.vemslog Trigger log http://www.vems.hu/files/MembersPage/PeterJensen/S2_log/v3.3_u016082-2018-07-08-19.26.39.triggerlog Any ides why there is no spark? '''Is there someone who can help Marius Helmersen in Norway or middel of Sweden, dealer, installer, retailer''' ----------------------------------------------------------------- * btw the most common reason is: SafetyMode ** VemsTune shows a big fat warning (and red flag) in that case, so usually noticed, but please check anyway. Very easy to upload full config (again) to fix it. ** another hint to check: VT version reasonably uptodate ? +Update ini files from web. * maybe ordered v3/16082 with some special, eg. HALL/HALL input ? The '''correct order of installation/testing''' * is to '''test inputs, independently of outputs: with outputs disconnected''', or disabled (removing fuses is easiest). ** including input-trigger(s), of course''' ---- '''Trigger voltage measurements''' * primtrig-VR (crank 135 pulse) DC voltage ? ** same with both ECU-s ? * sectrig crankhome-VR * cam-HALL DC voltage ? (when lo and when high) '''NEEDED: Config''' will be uploaded later. * Good, because it seems either config is the problem (which can be reviewed when uploaded); ** or trigger input; which can be tested on site. (capture and publish triggerlog, see InputTrigger/TriggerLog ) ** if no triggerlog pulses, '''disconnect the HALL sensor and insert temporary wire between GND and sectrig cam-HALL signal''' (assuming cam-HALL inverter, which is standard). => try again. Car is also tested using box AAN 3742 and the car is running perfect. * not a substitute for config and triggerlog, but useful info. ** note: the HALL of 3B can be outside the crankhome-VR, but not for the AAN. So not very likely in this case, esepecially if runs well. ** note: do the measured input trigger voltages (or better: waveforms) differ with the 2 ECU-s ? * what '''OscilloScope is on-site ?''' (now obligatory). Please make some ESD precautions, and follow install steps (including notes of verifications/measurement). Apparently running into more issues recently (of different kinds, that are difficult to link/relate, perhaps ESD or supply spikes, or some handling could be the common denominator - the probability that it is just luck falls exponentially after every issue ) than 10 other shops combined. ---- '''p259 outputs''' - suspect if VR inputs do not work. * tachout works ? (eg. DC measurement, test mode; or other indication of p259 working well) * anything else on p259 ? Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
