Summary of change:
== Introduction == I'm building a 1997 Hyundai Tiburon and trying to build it as fast street car. So far the parts list is as follows: ems- Vems 3.3 :) turbo-garrett gt2876R wg-Tial 38mm greddy BOV injectors- 780cc lowz wiseco 83mm pistons pauter rods arp head studs ---- == Status == I have hooked the vems to a 12v supply to start getting more familiar with it. All the sensors work but ive got a first problem with VR sensor but looks like people have had it already. It seems like the signal is very low beacuse rpm gauge shows no movement as i connect the sensor(tried to change the polarity) If the signal was erratic I would need some resistors to clean it but in my case what should be done? ---- TRY2 I tried to generate a waveform and input it into vems as rpm signal but with no luck so far... * method ? * parameters ? * result ? * we use ElectronicDesign/TriggerSignalGenerator on linux, usually ** m631 (63+1 that is 64-1) only for testing ** or m582 for 60-2 ** or c270 for 270 primary trigger pulse for 1 sectrig pulse (for auditrigger) The minimum voltage(mV) for LM1815 (VR) to trigger is appr 50..60mV * a PC soundcard with max volume is always enough If you have HALL, the DC offset might prevent triggering, since the (usually internal 10k, but can be external too) pullup resistor pulls up signal to 4.5V or higher. A pulldown resistor (330 Ohm .. 1kOhm towards GND) can be used to pull the signal to 1 .. 1.5V mean value, the PC soundcard's 2V peak-to-peak signal should work from there. I have VR sensor! Today I tried using a drill that had a screw attached to it and got the rpm reading upto 300rpm in vems but only when next trigger tooth was taken down to 2. With the another_trigger_tooth=1E (decimal 30) that will be used, one cannot rotate fast enough manually for the minimum RPM. This is OK. My methods were really wrong as i understood by today i think. I just generated a sine with waveform generator but now i generated a test wave with the software you told! Will do the test this evening. Will vems also start showing rpm from 50-60mV? my vems setup is: tdc after the trigger-45 nr of teeth on wheel 58 trigger tooth 1 - not sure about that next trigger tooth 30 crank min period 900 Tried the soundcard testing today. Could not get the soundgen to work but used ordinary waveforum generator again and i saw the rpm. It increased as i increased the frequency but i also got the trigger error :( Tested on a car also but with no luck yet. I think i would need a ossilloscope by the car to measure the signal... ---- Did some more wiring by now and tested the temp sensors. The intake air sensor seems to be off as it shows 34 degrees but it was around 20 outside but will confirm after some more testing. I can read rpm now but it drops off after couple of seconds of cranking and then comes back again. The rpm reads around 160 while cranking-also little low i think. Will test little better cable tomorrow. Kuuno, can you point me (Marcell) to the (Marko's) project page of the serialnr=583 v3.x ECU (6 IGBT, 400 kPa, VR primary trigger) that was examined and found to require > 300mV primary trigger signal unlike usual 50..100mV (and therefore it was replaced). Markos project page is currently the last one ---- Wiring-with injectors and ignition coil im using little bigger wires thna the ones that came with vems. VR trigger is using original vires that came with vems-not shielded just 3rd wire running as shield(cars original wiring was the same) sensor ground is conected to the chassis about 30cm from the vems unit. Megatune is 2.25 vems v3.3 1.0.38 have not used config.txt for configuration output of manmcd ---- <code> primep=0A primep_temp_scaling=05 cwl=2F cwh=0A cranking_thres=03 awev=41 awev_temp_scaling=0F awec=C0 warmup_clt_range[0]=00 warmup_clt_range[1]=0C warmup_clt_range[2]=20 warmup_clt_range[3]=34 warmup_clt_range[4]=50 warmup_clt_range[5]=64 warmup_clt_range[6]=78 warmup_clt_range[7]=8C warmup_clt_range[8]=AA warmup_clt_range[9]=C8 warmup_clt[0]=B4 warmup_clt[1]=AC warmup_clt[2]=A0 warmup_clt[3]=90 warmup_clt[4]=83 warmup_clt[5]=7E warmup_clt[6]=78 warmup_clt[7]=70 warmup_clt[8]=6B warmup_clt[9]=64 warmup_rpm_scale=BF req_fuel=1E divider=01 alternate=13 injopen=00 battfac=13 kpafac=C8 kpaoffs=92 injocfuel=2A injrampup_battfac=FF injpwm=FF injpwmt=0A injpwm6=0A rpmk[0]=0B rpmk[1]=B8 tpsdot_kpadot_conf=00 tpsdotrate[0]=08 tpsdotrate[1]=0F tpsdotrate[2]=19 tpsdotrate[3]=28 tpsaq[0]=01 tpsaq[1]=02 tpsaq[2]=05 tpsaq[3]=0A als_cut_mintps=FF tpsasync=02 acmult=C8 tpsacold=96 launch_enrich=00 launch_retard=00 overrun_fuelcut=14 overrun_fuelresume=13 rev_limit=32 airden_ignore=00 config11=31 config12=40 config13=02 batt_cal=BC fastidle=C6 als_max_cut=00 dbaro=0C tps_low=C8 tps_high=1C fan_temp=5F fan_hyst=05 fan_channel=FF iac_step_seq=C9 iac_conf=48 iac_max_steps=FF iac_tps_thres=08 iac_cold_idle_temp=90 iac_warm_idle_temp=C6 iac_cold_rpm=78 iac_warm_rpm=5C iac_cold_start_pos=E6 iac_warm_start_pos=D9 iac_afterstart_rpm=0F iac_afterstart_duration=96 iac_speed=32 iac_kp=14 iac_ki=0F iac_kd=1E launch_rpm=14 iac_integral_limit_dec=32 iac_integral_limit_inc=8C iac_integral_deadband=14 iac_deadband=0A als_cut_maxtps=00 iac_overclose_interval=80 iac_ref_pos[0]=BF iac_ref_pos[1]=B3 iac_ref_pos[2]=A6 iac_ref_pos[3]=99 iac_ref_pos[4]=8C iac_ref_pos[5]=80 iac_ref_pos[6]=73 iac_ref_pos[7]=66 iac_ref_pos[8]=59 iac_ref_pos[9]=4D iac_sol_channel=FF iac_ign_slope=20 softrpm_range=04 iac_ign_advance_limit=08 iac_ign_retard_limit=08 iac_ign_threshold=08 ego_conf=06 ego_lag=01 ego_coolant=B4 ego_maxtps=E6 ego_maxmap=80 ego_minrpm=06 ego_maxrpm=49 ego_warmup=3C ego_lean_limit=33 ego_rich_limit=0D ego_pid_kp=28 als_enrich=00 ego_delta=59 ego_target=19 ego_pid_window=FF wbo2_warmup_ramp=C0 als_react_tps=00 wbo2_abs_limit=F5 wbo2_limit_maxt=A0 wbo2_fallback=60 wbo2_retry_t=06 wbo2_edgetime_corr=BA wbo2_edgetime_min=50 wbo2_ri_target=9A wbo2_nernstdc_target=89 wbo2_pump_pw_zero=65 wbo2_calibration=CE wbo2_heater_pid_kp=46 wbo2_heater_pid_ki=10 wbo2_heater_pid_kd=1A wbo2_heater_pid_ilimit=80 wbo2_pump_pid_kp=15 wbo2_pump_pid_ki=37 wbo2_pump_pid_kd=00 wbo2_pump_pid_ilimit=FF wbo2_ri_confidence_scale=80 knock_conf=01 knock_sampling_window=FF knock1_frequency=29 knock1_gain=3F knock1_integrator=1F knock2_frequency=29 knock2_gain=3F knock2_integrator=1F knock_threshold=FF knock_noise_scale=FF knock_max_retard=00 knock_default_retard=00 knock_retard_step=00 knock_retard_delay=00 knock_advance_step=00 knock_advance_delay=00 knock_minrpm=FF knock_maxrpm=FF ve_learn_coolant=D8 ve_learn_max_power=FF ve_learn_rpm_scale=1E ve_learn_kpa_scale=1E ve_learn_ego_scale=43 ve_learn_min_weight=4D ve_learn_speed=FF ve_learn_limit=33 ve_learn_conf=00 lcd_c0=FE lcd_delay=FF lcd_backlight=FF kpa_conf=22 ign_balance=00 als_retard_mintps=FF als_retard_maxtps=00 lcd_default_view=00 primary_trigger=01 secondary_trigger=1F tooth_wheel=3A trigger_tooth=02 another_trigger_tooth=1E crank_minper=2C tooth_wheel_twidth1=02 tooth_wheel_twidth2=06 cam_sync_r_edge_phase=01 cam_sync_f_edge_phase=02 reset_engphase_after=F0 ign_tdcdelay=F0 ign_dwell14=37 ign_dwell6=38 ign_crank_advance=3C ign_out=70 ignchmax=01 engine_off_delay=0F pump_on_mintime=0B fuelpump_channel=FF inj_stage2_rate=FF inj_stage2_start_tps=FF inj_stage2_start_map=80 als_deact_rpm=FF als_deact_time=01 als_deact_egt=00 als_retard=00 als_rev_limit=40 misc1out_minrpm=01 misc1out_maxrpm=FF misc1out_mintps=FF misc1out_maxtps=FF misc1out_minmap=80 misc1out_maxmap=80 misc1out_channel=FF misc2out_minrpm=FF misc2out_maxrpm=FF misc2out_mintps=FF misc2out_maxtps=FF misc2out_minmap=80 misc2out_maxmap=80 misc2out_channel=FF act_wot_rpm=FF act_wot_channel=FF act_rpm_rpm=FF act_rpm_channel=FF egt1_cal=47 als_tks_channel=FF boost_conf=00 boost_targetoffs=00 boost_minpressure=80 boost_pid_kp=20 boost_pid_ki=80 boost_pid_kd=01 boost_pid_ilimit=FF boost_channel=FF water_pump_temp=00 hybrid_rpm_a=00 hybrid_rpm_m=00 water_pump_hyst=00 water_pump_channel=FF toothrel_normal=7A toothrel_missing=B5 fuelcut_min_kpa=07 fuelcut_max_kpa=80 tach_channel=FF tach_divider=FF shiftcut_conf=01 shiftcut_channel=FF shiftcut_time=00 softrpm_rpm=FF </code> The mct dump (tables) would also be needed to verify inj and ign sequence h[0] and h[2] lines ---- '''RPM hunt''' MegaTune configuration is-rising edge, multitooth(60-2), no filtering. This (primary_trigger=01) is fine. problem-rpm signal drops to 0 after every few seconds, no spark cranking below 200rpm '''VR polarity''' * tried changing the polarity but nothing changed! ** try again now with triggerlog and watching wheel error! * Original vr + wire is known from factory manual. So it is '''known for 99% which VR wire goes to GND in the factory install. But this means nothing!!!''' It often happens that the factory ECU triggers on rising edge and they mark VR+ what must go to GND in VEMS (VEMS triggers on falling edge). ** Marcell was tricked for several days with this, believing in the factory diagram too strong. This was the time when triggerlog was written, and it revealed the problem in 3 minutes. I have not soldered VR - to the sensor ground yet beacuse of tring different polarity. This shouldn't cause problem if connection is otherwise good (connected close to EC36pin26, at the same point or closer than GND5 connects). What part of InputTrigger/TriggerLog you didn't understand ? Reread, I made some quick-list notes. ---- wheel error counter increases continiously as I crank the engine! for testing i also ran separate shielded wire for VR to eliminate noise problems-using shielded mic cable(2 wires+isolation) * mde40 is for loggin all trigger event timestamps. Getting weird symbols with that from the terminal program. ** this is normal, it is the binary that you can capture, zip and upload ** you can also convert it but if you don't have perl installed, it's easier if we evaluate it ---- I uploaded the file with filethingi-created a dir under memberspage-kuunolotamois hope that helps i will read the triggerlog with reversed polarity also now-been trying to charge the battery for whole morning :) also mct dump (why do I get the spaces everywhere? encoding?) j[0]=4C80 4C80 5D80 6480 6E80 7180 7180 7380 7380 7380 7380 7380 j[1]=4F80 5080 6580 6C80 7480 7980 7A80 7980 7980 7980 7980 7980 j[2]=6080 6480 6B80 7880 8280 8480 8680 8280 8280 8280 8280 8280 j[3]=7280 7580 7D80 8480 9380 9880 9880 9280 9280 9280 9280 9280 j[4]=8080 8680 8880 8A80 9B80 A480 A880 A180 A180 A180 A180 A180 j[5]=8580 8980 9080 9380 A880 B380 B980 B380 B380 B380 B380 B380 j[6]=8D80 9080 9780 9C80 AF80 B880 BF80 BE80 BE80 BE80 BE80 BE80 j[7]=9280 9580 9A80 A080 B080 BA80 C580 C280 C280 C280 C280 C280 j[8]=9280 9580 9A80 A080 B080 BA80 C580 C280 C280 C280 C280 C280 j[9]=9280 9580 9A80 A080 B080 BA80 C580 C280 C280 C280 C280 C280 j[A]=9280 9580 9A80 A080 B080 BA80 C580 C280 C280 C280 C280 C280 j[B]=9880 A080 A280 A880 B080 BA80 C580 C280 C280 C280 C280 C280 l[0]=3D 36 2F 2F 2F 2F 2F 2F 2F 2F 2F 2F l[1]=37 34 31 31 31 31 31 31 31 31 31 31 l[2]=37 36 31 31 31 31 31 31 31 31 31 31 l[3]=37 37 37 37 37 37 37 37 37 37 37 37 l[4]=37 37 43 47 4F 4F 4F 4F 4F 4F 4F 4F l[5]=47 47 4F 55 58 58 58 58 58 58 58 58 l[6]=66 66 66 66 66 66 66 66 66 66 66 66 l[7]=6B 6B 6B 6B 6B 6B 6B 6B 6B 6B 6B 6B l[8]=6B 6B 6B 6B 6B 6B 6B 6B 6B 6B 6B 6B l[9]=6B 6B 6B 6B 6B 6B 6B 6B 6B 6B 6B 6B l[A]=6B 6B 6B 6B 6B 6B 6B 6B 6B 6B 6B 6B l[B]=6B 6B 6B 6B 6B 6B 6B 6B 6B 6B 6B 6B n[0]=3A 3C 60 87 A0 B4 B4 B4 B4 B4 B4 B4 n[1]=3A 3C 60 88 A0 B1 B2 B1 B1 B1 B1 B1 n[2]=3A 3C 60 87 9B AA AB A9 A9 A9 A9 A9 n[3]=3A 3C 60 86 98 A1 A2 A1 A1 A1 A1 A1 n[4]=3A 3C 5C 85 8D 99 9B 9A 9A 9A 9A 9A n[5]=3A 3C 58 77 83 8E 8F 8F 8F 8F 8F 8F n[6]=3A 3C 58 6F 7A 81 83 84 84 84 84 84 n[7]=3A 3C 58 67 6F 78 78 78 78 78 78 78 n[8]=3A 3C 50 5F 6F 78 78 78 78 78 78 78 n[9]=3A 3C 50 5F 6F 78 78 78 78 78 78 78 n[A]=3A 3C 50 5F 6F 78 78 78 78 78 78 78 n[B]=3A 3C 50 5F 6F 78 78 78 78 78 78 78 k[0]=0A 0F 14 19 1E 26 2D 35 35 36 36 37 r[0]=05 0A 0F 14 1E 28 32 40 41 42 43 44 h[0]=02 08 04 01 10 20 40 80 h[1]=00 00 00 00 00 00 00 00 h[2]=00 01 02 03 04 05 06 07 b[0]=14 18 1C 20 24 28 2C 30 80 80 80 80 t[0]=20 40 60 80 A0 C0 E0 FF
