No Spark on SR20DET, wasted spark

[clem]

Hello there!

I have wired an EMU to my sr20 powered S13. I am using a bosch 2x2 double fire coil without amplifier, and there is no spark appearing...
Ignition status is synchronized, but with the timing light says that there is no spark. The car never run before and I am wondering if there is a hidden spark disable function similar as for injectors? Any Idea for that problem, or has anyone had a similar problem before? Coil fuse is ok, all other fuses too.

Many thanks

Din you activate the ignition outputs under ignition outputs?

Hi, thanks for your reply.
yes I had activated the outputs, like in your description. see my picture:

is there an other option to disable the coils to fire?

Please send a picture of you ignition configuration and log file from cranking.
Do you use Nissan trigger ignition type ??

Well I connected the Coil like in the EMU manual described. Battery to coils via 15A fuse, each coil to one Ignition output (output 1 (G8) for cyl 1&4 and output 2 (G16) for cyl 2&3). I can not provide a log file until thursday night, sorry. which parameters would you like to have logged (or are all parameters included in the exported log)?
Yes I use the standard Nissan Cam angle sensor from this engine. Emu even says ignition is synchronized!
here my trigger settings:

Even if the engine won´t start because I connected the wrong ignition cables to the plugs, there would be at least a spark visible with the timing light...
thanks!!

The 12v cable to the coilpack is ignitionswitched and not direkt from battery i hope?

[Jadzwin]

You have put VR sensor for CAM sensor type.

Here is proven trigger config for SR20DET



Check if there is +12V on the coils during cranking.

Thanks for your help. I will check these settings when i can get to my car again! Sorry for the bad description, yes the coil is ignition-switched...
see you!

Hi there.

Thanks for your help! Car is running now (more or less), it is a question of tuning now.
The problems were: Firmware mismatch, Trigger settings.

Thanks jakub!!! Kind regards
