Re: Cylinder contribution

https://www.picoauto.com/library/automotive-guided-tests/diesel/ Perhaps you want more of what Burt 100 was listing. It was strange the page on this website for the petrol version of the test I was suggesting was missing. But that is a link to the diesel version. I would think this would give you s...

Re: Cylinder contribution

I believe there is a built it relative compression test based on that setup built into the picoscope diagnostic software. It has everything to help you run that test. It is one of the tests I've just added to my initial tests. Verify soundness of engine mechanical . Check it out.

Diagnosising old school ignition coil

Had a car come in a couple months ago that gave me a good slap in the face. 1970 Chevrolet Corvette with stock electronic ignition. I did a re-curve of the distributor, and overhaul / rework of the carburetor. This was done to help deal with the changes in gasoline since the vehicle was produced. I ...

Re: Raster Parade, etc,..

Had to add a little more. With the raster display you can so quickly pick up on timing event issues. Like a slack timing chain albeit a mechanical issue. And so quickly. The parade pattern can't give you this. With just a very quick hook up the amount of knowledge that can be viewed is priceless. Be...

Re: Raster Parade, etc,..

Not sure why I wasn't getting notifications for this thread. Thanks all for your input. I had totally forgotten my MixMaster. I own one! I use to use it with my one Ls2000. It was not that easy to use with it. But I will pull it out and try it on my Pico. Why didn't I think of that. I did end up pic...

Raster Parade, etc,..

Just had a double loss of two scopes at the shop. We had an old Sun 900, and I had a Vision Premiere digital scope. Lost hard drive on the digital one, and my wave pattern is no good on the Sun. I am left with my Pico 4423 scope. Good scope for a single cylinder. I want my cylinder kill funciton bac...

Re: po125 fault code

We don't have this exact model in the US but that shouldn't matter. Mitsubishi version of P0125: Engine started (cold); and the ECM detected that the ECT sensor signal decreased from more than 104ºF to less than 104ºF or the ECT signal did not reach at least 104ºF in 5 minutes, or the ECT sensor sig...

Re: Looking for Insights in diagnosis of a Large POP On acce

Ended up under the gun for time. Replaced the Distributor as a whole. Problem gone. I will put the old distributor on the distributor machine this coming weekend and hopefully get some patterns. I had already changed the module, and coil wihout any improvement. The wiring didn't seem to have any fra...

Re: Looking for Insights in diagnosis of a Large POP On acce

Thanks Robski, I'll be giving autonerds a call. Just got a dedicated pc for the Pico Scope. I didn't know there were better cables I could get for Ignition. I've been using a much older OTC automotive scope for Ignition. Only switched to Pico when I had to take it for a drive. I'd like to be using i...

Looking for Insights in diagnosis of a Large POP On accel

Hoping to tap into all the minds here for some insight. Our shop seems to be changing direction and going back to the 50's and 60's. Usually working on cars where I can use a scan tool to great advantage. I think I've gotten a bit rusty with the older cars. I've been spoiled by being able to hook a ...
