Re: Frequency waveform for 8-wire digital MAF

Thank you Steve,
I do have the 4423 but it is good to know that all is normal. The interference doesn't bother me now that I know that it is normal. I will try your tweaks next time. Happy New Year :D

Re: 2010 VW Golf 1.4L TSI Compression Leak

Hello all, my sincere apologies. I keep forgetting to tick the notify me box :oops: I am humbled by the amount of discussion this has produced. As many of these diagnostic cases go the customer never gave me the opportunity to do further diagnosis. I haven't seen the car since. I would really like t...

Re: Resonance and Natural Frequency

Thank you for all of the effort in your response. I must have forgotten to select the notify me of a response so I didn't see your post until today. My main issue was with the 1-2Hz which you have cleared up by attributing that value to the body itself. Thanks again.

Frequency waveform for 8-wire digital MAF

Hi all, I'm looking for some advice on the waveform I've take from a 2015 Holden Commodore 3.6L V6 SIDI which employs an Hitachi 8-wire MAFM (GM actually call it a multifunction intake air sensor). These new MAFM's output Air Mass, Humidity, Baro and 2 air temp values. With all of that said my captu...

Resonance and Natural Frequency

Hello suspension experts, I'm a trainer and trying to clear up an inconsistency. In the PicoDiagnostics NVH Assist files it states that the natural frequency of a vehicle suspension is 10-15Hz and some newer vehicles are up to 20Hz. I have also seen other resources out there that state a range betwe...

2010 VW Golf 1.4L TSI Compression Leak

Hello, I have a 2010 VW Golf 1.4L TSI in the workshop with a Compression Leak in cylinder 3. It is only really noticeable at idle. The engine ECU is picking up the misfire and logging #3 misfire codes. No evidence of previous overheating issue, one owner and 160,000km on the clock. Spark Plug and co...

Re: Primary voltage on a waste spark distributorless ignitio

Regarding the burn time at zero volts, remember how we are testing and measuring the secondary firing voltage. (Using a near non contact, capacitive pick up COP probe or pick up leads) This is what I was trying to grasp!!! Thank you again for all of your support, top product with fantastic support :D

Re: Primary voltage on a waste spark distributorless ignitio

That is great and it would be handy if some of these newer systems could be added to the 'in tool' library ;)

There is only one last thing that I don't understand about my waveform and that is why the burn time is at 0 Volts?
Has it got anything to do with how I have set up the scope?

Re: Primary voltage on a waste spark distributorless ignitio

That would be wonderful Steve, Thank you:)

:idea: NOTE TO ALL NEW PICO USERS :idea:
Remember to turn off your inductive amp clamps when you are finished each job, otherwise they'll be flat when you go to use them next time :?

Re: Primary voltage on a waste spark distributorless ignitio

Hello all, sorry for the delayed response. After refitting the faulty coil and getting the faulty ignition primary current waveform I left the file unsaved while I reassembled the car. My daughter (on school holidays) came along a played with the computer and deleted my image... I didn't realise thi...
