Summary of change:
'''LANCIA DELTA INTEGRALE HF 16V''' rallycross cars. *2L engine *4 Cyl *turbo *36-1 toothweel with VR trigger ** no camsync *wasted spark coil *4 bar MAP sensor, about 1.7 - 1.8 bar boost *permanently opened throttle body for ALS There are 2 cars here, they are almost the same, except one of them has high impedance injectors, and the other have low impedance injectors. The cars was running succesfully from a year with VEMS, and with 1.0.38 firmware, everything was OK. They use start limiter and boost control too. Now the cars came back. They need ALS. I uploaded the prereleased 1.1.7 firmware into one of them. Here are the config files: [http://www.vems.hu/files/Fero/Lancia/config.txt config.txt] [http://www.vems.hu/files/Fero/Lancia/tables.txt tables.txt] [http://www.vems.hu/files/Fero/Lancia/Lancia_SZABI_04.msq lancia.msq] ALS works almost perfect, but i realised some minor problems. We need an ignition cut gauge in megatune to easy tuning, and also we should take into the log the actual ign cut. Hungarian: Szerintem 0 foktól kellene megadni a retard értékét mert ha be van kapcsolva az ALS kapcsoló és elértük az idõlimitet akkor az alapjáratot a soft ign cut limiterrel tartja a kocsi, ekkor a gyakorlatban jólmûködõ ALS beállítások mellett még mindig retardolja a gyújtást a vezérlõegység, amire semmi szükségünk nincs. Nekünk csak a negatív gyújtástratomány a lényeges, és 0-tól nyugodtan válthatunk azonnal a táblázatban szereplõ gyújtásértékre. Here is a log file, you can see that the spark retard and the fuel enrichment works good in the 1.17 firmware: [http://www.vems.hu/files/Fero/Lancia/log5.xls ALS log] ---- '''One car runs fine with 1.1.8, but the other does not even start''' We must closely examine the config and tables difference between the 2. * There is no RPM signal. * does wheel error keep increasing ? Old 1.0.38 firmware, but the isn't with the new 1.1.8 firmware. Here are the files: * [http://www.vems.hu/files/Fero/Lancia/configFeri.txt config] * [http://www.vems.hu/files/Fero/Lancia/tablesFeri.txt tables] What files are these ? * The 1.0.38 config that works (with 10C engine) * or the 1.1.8 that works * or the 1.1.8 that does NOT work (with 0C engine) You should '''provide all 3 sets''' so we can compare and give you better hints. * I made trigger logs with the 1.1.8 firmware. I removed all the spark plugs (while capturing triggerlog), so no accelerations and decelerations on the carnk. ** [http://www.vems.hu/files/Fero/Lancia/trigger4.bin.txt triggerlog_bin] ** [http://www.vems.hu/files/Fero/Lancia/trigger4.txt triggerlog_txt] If the car runs with 1.0.38, there is no need to change the triggerwheel. We've seen that it's a sloppy wheel. In triggerlog the time ration is often 1.45 instead of 2.0 (remember: this is N-1 wheel) during cranking, but multitooth advanced filter (primary_trigger=09 instead of primary_trigger=01 switches multitooth advanced filter on) set to * 50 .. 125% for normal tooth * 125 .. 300% for missing tooth After it starts, at RPM >500 the RPM variation during 180 crankdeg is not that severe. Normal toothwidth=40, missing toothwidth=80 look good for 36-1 wheel. reset_engphase_after=160 looks good when no camsync is used. * tooth_wheel_twidth1=28 * tooth_wheel_twidth2=50 * reset_engphase_after=A0 ---- '''Ignition outputs''' You are using 2 different set of reftooth => ignout mapping. This fires ignch2 after reftooth 0: * h[1]=00 12 00 12 00 12 00 12 * h[2]=20 30 20 30 20 30 20 30 This fires ignch2 after reftooth 18: * h[1]=12 00 12 00 12 00 12 00 * h[2]=20 30 20 30 20 30 20 30 That is 180 degrees difference. '''Clearly, only one can be good'''. This is the most likely reason for one engine not willing to start ---- '''Injector outputs''' Please elaborate on injector wiring and sequence. '''If''' * firing sequence is cyl 1,3,4,2 * and wiring is "straight" cyl 1..4 wired to injector output A..D, than any (of the 4 possible) rotation of 01,04,08,02 mask-sequence (remember to read from bottom to top, in MegaTune) is good: * h[0]=01 02 08 04 .. .. .. .. Note that this does not effect RPM=0, and even does not prevent the car from starting. But verify and confirm to prevent one cylinder leaning out in some conditions. ---- '''Other''' 3 degrees of cranking advance is extremely low (6..10 is more common), if the base timing is set correctly * ign_crank_advance=0C --------- '''News:''' Because the RPM=0 problem, we thought to change the triggerwheel. It does not seems good too. It was rusty, and not harmness. So we chenged the wheel, also we'll use a HALL cranksensor insted of VR. http://www.vems.hu/files/Fero/Lancia/HALL_LAncia.jpg The missing tooth is about 90 crankdegrees BTDC. The trigger settings for this 12-1 wheel, with the new firmware(1.1.11) (GenBoard/UnderDevelopment/FirmwareChanges) *primary_trigger=01 # multitooth without advanced filter *secondary_trigger=02 # disabled *tooth_wheel=0B # decimal 11 tooth *trigger_tooth=01 # *ign_tdcdelay=78 # 60 crankdegrees *another_trigger_tooth=06 *tooth_wheel_twidth2=78 # 120 means 30deg *tooth_wheel_twidth1=F0 # 240 means 60deg *reset_engphase_after=A0 # no camsync If ignch2 and ignch3 are used, in a wasted spark way: * h[2]=20 30 20 30 .. .. .. .. * h[1]=00 06 00 06 .. .. .. .. Change to * h[1]=06 00 06 00 .. .. .. .. if you connected ignchannels to cyl-pair 1,4 and 2,3 the other way around. (or change h[2]) ----- New megatune MSQ file with 1.1.12 firmware http://www.vems.hu/files/Fero/Lancia/new/LanciaFeri_00.msq
