Summary of change:
I have set up this project page for the issue I have with no injectors or coils firing, after having the ecu repaired (Chip replaced) for pegged exhaust temp @ 1200 deg. [http://vems.hu/files/Audi%20S2%203B%20Alex%20J/ uploaded files] also a trigger log done after I received the ecu back when I was investigating the no start issue. the care is a 3B engine using an ANN ecu. pins have been swapped in the motronic55 female connector. car was running as you can see from the log I uploaded. ECU serial number is 1450 firmware 1.1.95 although 1.1.96 was installed when I received it back. I think I changed it to 1.1.96 just before I removed it to send away. ---- '''Speculation''' * perhaps his new board has camhall invert and old board did not ? ** RPM reading would be fine with inverted camHALL, just ign firing 360 degrees off. (but in the new logs, RPM=0 all the time) * Dave Brul: I do not see any showstoppers in triggerlog or config, other than secondary pulse being very close to primary pulse ---- '''EGT K-thermo tip broken''' * EGT readings lifts significantly when cranking is initiated (from 222 to 768) ** '''most likely cause, EGT tip grounded (broken probe)''' Although this, in theory shouldn't damage the ADC597 chip (which was damaged earlier), who knows... In any case, a new K-thermocouple will be needed. ---- '''Before / After''' Comparing config before/after (the ecu repair): diff -U2 alex18_before_repair.vemscfg v3.3_u001450-A-2014.03.28-17.25.55_after_Repair.vemscfg Suggests: Apparently some innocent calibration differences (eg. nernst dc target was wrong before) but only max_prim_per_sec_count could effect triggering. <code> @@ -43,5 +43,5 @@ battfac=22 kpafac=D0 -kpaoffs=94 +kpaoffs=90 injocfuel=08 injrampup_battfac=FF ... -wbo2_nernstdc_target=80 -wbo2_pump_pw_zero=82 +wbo2_nernstdc_target=84 +wbo2_pump_pw_zero=67 wbo2_calibration=ED wbo2_heater_pid_kp=45 @@ -238,5 +238,5 @@ act_rpm_rpm=FF act_rpm_channel=FF -egt1_cal=4B +egt1_cal=49 als_tks_channel=FF boost_conf=69 @@ -299,7 +299,7 @@ bla_8[0]=65 bla_8[1]=65 -bla_8[2]=65 -bla_8[3]=65 -bla_8[4]=65 +vvti_measure_tooth=00 +max_prim_per_sec_count=FF +sd_logging_mode=3F boost_pwm_max=FF boost_pwm_min=71 @@ -448,5 +448,5 @@ prohibit_config=00 prohibit_h=04 -prohibit_l=DF +prohibit_l=E0 config_switch=07 vtstorage[0]=7F </code>
