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, only primary trigger (=crankwheel HALL - is it HALL for sure??) will be used for now.

This crankwheel is very smart construction, because it can sync in half revolution (often even earlier!).

We made some modifications to signalgen to generate the wav sound files to test the trigger setup on the table. Firmware code was tested against this.

The trigger is supported from 1.0.38 with the following setting (multitooth, no camsync):


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.
