I did measure, EC18/17 is internally connected in ECU to EC36/26. Should i change ground to EC18/17 pin? ** Can you measure with DVM that EC18/17 is internally connected in ECU to EC36/26 ? (been the standard for quite some time, but if the ECU has dual WBO2, or an old ECU, then EC18/17 is not grounded internally so GND connection from EC36/26 must be maintained externally) * Do you have some other +5V source to try? (eg. a wired-in 12V=>5V regulator, or cut the USB cable from a failed mouse, find GND and +5V, take care of polarity, and supply from a cigarlighter USB socket) * '''fuel pump is turned on when pulses detected on EC36/pin26 primary trigger.''' * for VR sensor (depending on LM1815 adaptive threshold setup), even low amplitude (eg. 140mV to allow starting in winter with depleted battery) pulses can trigger. ** however, for HALL (which provides <0.5V and >4V signal), much larger swings needed, and definitely grounds should be checked ** just the android serial stream should NOT cause fuel pump to turn on, so definitely find some GND or +5V disturbance to HALL sensor. ** Although normally should not be needed, might help: an added 47uF or 100uF (min 10V but rather 16V or 25V electrolitic) capacitor in DSUB9 housing between DSUB9/pin5 (-) and DSUB9/pin9 (+5V), take care of polarity '''A)'''YES +5v from EC36/28 NO, Connected to main ground like prebuilt harness, as before I added +5v. * I did measure, EC18/17 is internally connected in ECU to EC36/26. * Should I change DSUB9 ground to EC18/17 pin? * theoretically RS232 GND should be fine either EC36/26 or EC18/17 (as they are confirmed connected inside the ECU) ECU ground Should be OK? http://www.vems.hu/files/PatrikGolf/ECUearth.JPG What if you '''make a DSUB9 connection to the notebook with ONLY DSUB9/pin5 GND''' ? (no pin2/pin3 communications). * Does the notebook disturb the engine GND even than ? * what if notebook is powered from battery, not the mains ? ** sounds like the notebook ground injects surprising level of noise into the engine GND (or perhaps into +5V or HALL signal, but that is less likely) ** does the engine have any other connection to mains ? Like a charger attached ?

'''A''' * Please apply the setting as suggested: "first trigger tooth = 4, tdc after the trigger = 60" * Than after rebooting the ecu first (power cycle through ignition), take a triggerlog in format 8-10 seconds cranking without IGN and INJ fuse and sparkplugs mounted (so compression cycles can be seen). * upload the triggerlog to your FileArea and link it here so i can review. we'll work from there.

Looking very good, spark position appears to be in the right spot ~tdc. * you should be ready to start the engine now and proceed to tuning after fine tune (and double check) of tdc after the trigger with strobe light.
