The car got an 1.6L 4cyl NA engine because it is believed to better compete in that class, compared to the 1.8L engine.
The deadlines are very tight, it should be ready for race before 2006-03-17
With a standard trigger, it should be no big deal, but this engine has a special trigger.
IAC
Simple bipolar stepper - should be straightforward
Ignition
Wasted spark. Coil on plug style. Yes, only 2 transformers, each have a second high voltage connection for the cyl pair (1-4 and 2-3).
MAP / AlphaN
The engine has a MAP sensor. However, because of very aggressive cams, some loadsites might need to be tuned from TPS (AlphaN).
Trigger
The engine has camsync, but because of wasted spark, primary trigger (=crankwheel HALL) will be used for now.
Firmware code must be tested for this special crankwheel
- we made some modifications to signalgen to generate the wav sound files to test the trigger setup on the table
The trigger is supported from 1.0.38 with the following setting (multitooth, no camsync):
- primary_trigger=01 # multitooth (advanced filter is not applied; actually, advanced filter could work with N-1 setting)
- secondary_trigger=02 # disabled
- another_trigger_tooth=12 # decimal 18, no surprise
- tooth_wheel=20 # decimal 32, no surprise (36-4 wheel)
- trigger_tooth=44 # decimal 68; tooth 4 selected (0..12 could work with different TDC position), but 64 is added because of implementation reason
- ign_tdcdelay=78 # decimal 120, that is 60 degrees; according to drawing, TDC is 60 degrees after tooth 4
A describtion of the trigger (HU; just to confirm the direction and position seen on the image):\n
Mind1, itt küldöm a képet, immáron dedikált lendkerékkel. A felsõ holtpont fizikailag ott van, ahol a lendkerék tövében a csap van. (azaz van 6db felfogató csavar + 1 tájoló csap, na a csap van felül holtponton) A jeladó ehez képest lejjebb van, gondoltam azt a bordát jelölöm meg, amit "lát" a szenzor felsõ holtpontban. Komikus mód ez úgy semmilyen rendszerben nincs semmivel se. Utána a forgásirány szerint még kettõ bordát "olvas" a szenzor, és kezdõdik az elsõ kihagyás. Udv Yas Azt hittem soha nem fox feliratkozni.:) Lenne 1 kersem:) Ha lehetne akkor kommentalnad magyarul is a torteneseket? Lassan azert tanulok angolul:) A_Feri/Saybor:)
