Consult connection only at "ON", not when running engine

Hi
i'm having some trouble with my self buildt consult interface.
the interface is based on this schematics: http://consult.hackthebox.org/files/...schematics.pdf
The problem is that i only get connection to the ecu at Switch/key setting ON(next to cranking) but nothing when the engine runs.
any hints to what i could be?
The car is an Euro Primera P10 1994 model(Almost similar to Infinti G20 P10) with Sr20De engine.
i've tried diffrent softwares but it doesnt seem to work with any...

I also have this issue. I read TPS, MAF, Injectors, etc. when not running. Once I turn it over, nothing. Bump.

what circuit are you using zexel? and are you sure to restart consult software once engine is started (as connection might be loss due to cranking drop in volts)

as ive told the original poster via email a few days ago, its most likely the ECU transmit in the circuit (top part with R1), if you dont use a schmitt triggar input like HC14 to output a 0-5v square wave (since using just a resistor ends up with a more rounded wave, and closer to 1-5v), then use a single R1 10-15K and remove R2.

Finally messed with the car after a few weeks. Got the program to run today. I had an issue with my connection, I believe. It works great now! Thanks.
