Re: 2009 Iveco Daily IV 2.3 jtd 94KW No rail pressure

Hi, Looking at the capture there may be some connection issues with grounding but that aside you have a duty cycle of around 50% which shows the ECU is sending a command to the pump which would allows some fuel into the pumping chambers to start creating flow. Given you have 0 Bar of pressure I woul...

Re: New guided tests

Thanks Paul. It's nice that they are out there and out of my brain mostly! Couple of bits of snagging to do but on the most part they should be useful.

I've got some ideas for the next ones but if you think of anything please let me know.

Kind regards

Ben

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? ...
