pico diagnostics latest beta version
Jan 28^th, 2010 at 7:13am

I just downloaded the latest version of pico diagnostics 2.1beta (think thats what it was) from picos web site today. i have had it on my laptop before and i was hoping to get the battery tester test that i have seen advertised. is that included with this update? also is anyone using the battery test? is it accurate? all the hook ups are the same as any other batter tester. is the cranking and starting loads enough to pass/fail and is running for 10 seconds enough to check charging? does it even check charging or is it just a battery/starter test? the pico diagnostics seems pretty accurate in the playing around with my own car ive done as far as causing missfires and pulling spark plugs and cranking to cause a low cyl psi and it cathes all the little glitches i can make. of course it wont ID the cylinder thats the culprit but it lets you know there is a problem. PERSONALLY i usually dont use this software on a customers car b/c in the sake of saving time i want to ID the cylinder thats the problem in the relative cranking amps or exh pulses so i use those tests to ID problem cylinders and relative cranking compression or missfire diagnostics since the hookups arent much harder. SO, who else uses this software as well? Sorry for the long post with random scattered questions. This is my first post on this website and all the content and discussions seem first class with great info and great waveform sharing! thanks!

Hi Shaun, I will have a go at trying to answer your questions.

Yep, 1.2.1 I think. It's been around since middle of last year.

This version has the battery test. I have had very mixed results with it though. I use it occasionally but get alot of errors and negative readings. i believe It will show internal resistance of the starter, condition of the alternator. ie ripple and output. and battery condition and recovery time. I find i have to be very precise with my battery initial charge and the time it captures for. If you leave it to long or not long enough you will get strange errors.

Have you tried connecting a second scope lead? I think you will find it will recognise an injector of ignition signal to sync your cylinders. Don't forget the attenuator

Well, Me! I use it as much as i can. If I have a vehicle that I suspect a compression issue with I start with Pico Diagnostics relative compression test so I don't waste time on a 'crook' motor.

Thanks for the responses Rod! the reason i asked about the battery test was b/c after downloading and rebooting i didnt see the battery test option anywhere on the program.
As far as using a sync i usually go off cyl1 coil or secondary or whatever is close and not buried. so your saying pico diagnostics will sync to a cyl? obviously it wont know if im on cyl 1 or any other cyl but will this point of reference then become cyl A for example on the programs relative compression test? to be honest i have not tried syncing with anything when using the pico diagnostics mostly b/c it doesnt direct you too. i will deffinetly try this next time to see if it gives me the accurate results your saying it does. good job just trying it and figuring that out! guess i was just too ignorant/lazy to even try Huh

thanks again

Hi Shaun,
I should have elaborated a little more.

Quote:

Yep, exactly. The software still identifies the cylinder as CylA, CylB, etc. What I meant is if you show the waveform at the top of the program by clicking on the little message box in the botton right that states something like

All cylinders are above ...%

you can see the sync signal from your second lead in the waveform at the top half of the screen.

I tried to add an attachment to show you what i mean. hope it works.

rod_au likes to key press and mouse click and even hover everywhere on new software!! Ya never know what the developers have added to the applications that isnt documented!
