plox Posted January 20, 2019 Report Posted January 20, 2019 Hi all Has anyone seen a Lag or Freeze in logging data like the below? (clearly visible where everything flat lines for around 1 second before unrealistically jumping 1k rpm or 30% idc) https://drive.google.com/open?id=1YXMsvvHNLX_3M3WdGF5wqokXmlFjgANe It only happens on the highest boost setting (of 3) when I have water/meth active and it happens right before the WM actives. Other 2 boost settings show no issues. I am wondering if it’s to do with the current the water/meth solenoid is drawing, the prometh solenoid is listed as a 3amp draw so I’ve wired the earth direct to the ECU and it’s controlled via a PWM output. I am wondering if this would cause the logging to freeze? The car doesn't stumble or reflect what's in the logs. Cheers in advance Quote
Adamw Posted January 21, 2019 Report Posted January 21, 2019 It looks like a USB comms drop out to me. It could be the flyback from the solenoid interfering with USB or possibly ignition noise etc. Can you do an ECU log instead? Note the aux outputs are only rated for 2A so that solenoid should really be wired through a relay too. Quote
plox Posted January 21, 2019 Author Report Posted January 21, 2019 Sorry, 0.7amp draw after re checking the solenoid's Spec's. I could wire the solenoid through a SSR but figured it was unnecessary due to low draw. I'll do an ECU log tonight and report back to see if it has the same affect. Quote
plox Posted January 22, 2019 Author Report Posted January 22, 2019 I found it happens when flicking the medium boost switch also, but not the high boost switch (also happens when the WM solenoid activates). low/medium/high+WM is on a 3 way switch, so WM is not the only thing causing the freezing in logging. And yes it is PC logging only, this is both ecu and pc at the same time and me flicking the switch back and forth (bottom you can see the linear AFR's from the pc log): https://drive.google.com/open?id=12giK3etxj4fSMw27OotCOcZ9pVrWjcn2 Would it be worth testing another PC?

Adamw Posted January 22, 2019 Report Posted January 22, 2019 Yes worth trying another laptop, some have more robust noise immunity than others. Also check through these suggestions from the help file: Quote
