Alien Logging

After the FirstProblem is solved I want to log my Ignition to get an Idea how much Advance vs. boost i have. Do i need to populate the second LM1815 Chip? I want to log the Ignition in the car, because my Ignition have two triggers (first one every 180deg on TDC Cyl. 1+4 and on TDC Cyl. 2+3, second one 122teeth per revolution at the Starter gear). Is it right that i need a cable from the Coil Pin 1 to the input of the second trigger?

In my_make:

LOG_ALIEN ?

SEND_DWELL_NOT_IAC ?

CAPTURE_ALIEN_ECU O.K.

MS_COMPATIBILITY NOT defined O.K.

MSNS NOT defined O.K.

See my notes on OnlineCourse/AlienIgnitionLogging

In global.h i found for trigger2:

bit0 0:falling/1:rising,

bit1 0:enable/1:disable,

bit2 0:no filtering/1:filtering,

bit3 0:toothwheel/1:coil,

bit4 0:alien advance/1:cam sync,

bit5 0:single edge/1:both edges when cranking

so i think config.secondary_trigger=13 ?

Sensor Calibration

The most frustrating work for a newbie is Sensor calibrating.

I changed the gentherm2 utility for my needs. You put the three temp-resistance Pairs in and get a hex file out with which you can patch vems.hex. I put my Sensor calibration Data and this program into [Sensor Url].

I found a little Problem with hexpatch and my VDO cltfactor file:\nÿ1ÿ

Maybe somebody knows why this is?

If I patch the vems.hex with hexedit - no problem.

at the Bias Resistor is adjustable.

I used Lcc to compile it (under Windows). I uploaded everything under: [Sensor Url].
