Re: NVH Road Test

Pilot Error !! Have we eliminated that conclusively? Maybe the software engineers at Pico could provide some advice about what pc's we need to invest in for the latest versions of pico software! Indeed, they sit there twiddling their thumbs all day with nothing better to do. Pico Automotive scopes ...

Re: NVH Road Test

Steve,

I have the NVH software file at work on my latest industry PC. I can confirm that the software operates OK and does not seem to lock up. New pc's required then.

Thanks again Steve for your invaluable help.

I did a cylinder balance test using Pico diagnostics and when I was observing the bar graphs the bar graph B never changes from 1.00. When I did a cylinder compression test using Pico diagnostics all four cylinder bar graphs move. A relative compression test shows no problems with either starter cir...

Re: Secondary Ignition scope analysis

It is well documented around the globe that testing anything looking for errors is best achieved by loading and stressing that subject to force the error. For secondary ignition that is not going to be achieved at Idle, 1500 rpm or 2500 rpm. Cannot be achieved at any RPM really. If you don't know h...

Re: Secondary Ignition scope analysis

Waste spark system is best checked at idle since you have the advantage to see a spark under no compression. Really ?? Then why don't we check spark with the spark plug removed ? In atmosphere !! I have always seen compression lower at higher Rpm then at idle too. Something not adding up here ! Ive...

Re: Secondary Ignition scope analysis

Hi technician, I'm looking at your first post (screen 7) you are running at around 800rpm.Your cyl.4 shows some odd behavior which is a characteristics of pico's secondary leads. The data is not valid anymore when you see those jumps. There are 10000:1 leads available which are a lot better, but do...

The aftermarket telling me that silver calcium batteries were not required. Auto-electricians telling me that they had repaired faults in the alternator and that it was now working fine, only to find that later the battery still discharged. I fitted an OEM alternator from Ford myself, and a silver ...

Re: Secondary Ignition scope analysis

I've done some more ignition scope tests this evening. They look a lot better and I think the main problem is how I'm setting up the scope and whether the leads connected to the plug leads are very sensitive and allowing interference? I decided to pass the leads through the bonnet hook and let them ...
