Re: Diesel engine knocking as if something loose when in operation.

Hello, Just wanted to add a couple of thoughts. The first one being pump timing. I know these will be geared so there isn't any movement and being a new tractor with low hours, it's unlikely but not impossible. Following on from the post where we looked at using the derivative maths function to look...

Re: Maf frequency measurements problem

Thank you for the capture as it really helps to understand how to recreate the issue. It appears that this was a problem that has now been resolved in the latest Early Access version. Would you be able to try this version of PicoScope 7 Automotive for me and see if you are still seeing the problem? ...

Re: Canbus issues

Hello Burt_100, Thank you for your post. Lets tackle one thing at a time and to start with that it seems to not decode. This was due to a slight oversight in the decoder settings where the threshold was set to 3.6V and so outside of where the packet actually is. The decoder will try to fit the signa...

Waveform library

Hello all, I'm after some help. We all know that PicoScope can be used for more than just automotive vehicles - hence this section of the forum. It would be great to see more and more non automotive waveforms in the waveform library. Could I ask that if anyone as any waveforms that might be suitable...

8 wire, brushless DC motor

Recently I found myself going back over some old captures to see which ones might be useful to upload to the waveform library and I stumbled upon some captures I made to follow up on the JCB JS220 EGR fault case study. You can see the full case study here - https://www.picoauto.com/library/case-stud...
