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:

Maybe somebody knows why this is?
If I patch the vems.hex with hexedit - no problem.
Hope it helps.
