I was searching the web on the Pico NVH and came upon a 5 part video series a gentleman at a college put together.

Really nice documentation in my opinion. I am not into vibrations diagnostics to much, but if Tom can give me a deal on the tool and I can make a $$$ and learn something. I am all in for it

Once in a while with my long term loyal customers. I through them a bone and give them a deal

I did go through the other video's. Been watching them for the past two days. The evolution of the NVH has come a long ways.

The issue with the other tools is being outdate and the more modern you got the software got outdated.

This is so true. I think the ROI could be seen in one year.

The thing I would like to try is to use the tool on the engine. Wonder how sensitive the tool is for lets say a misfire or using it for other practices.

I would like to see the microphone in operation. I wonder what uses we would have for it. 

I would like to demo one of the tools to find out. May be see if my buddy at the GM dealer has theirs and see if I can use it.

It's not like the use it anyway. Most stuff like this sits on the self

I believe it is variable. Shall we find out?

Also note with this method we could have more than one PID or CAN I.D. being graphed at the same time.

Ian, that was a really nice article. Do you have the NVH tester at your disposal?

I contacted my friend at the dealer today. They are actually waiting for their kit. They have 20 Chevy pick ups experiencing vibration issues right now. Gm engineering the dealer to rule out all possibilities before condemning frame issues.

With this being said, GM has revamped their frames with a body design change which is raising havoc with NVH issues.

Curious to see what GM will do to resolve this.

Bob, The dealership that I work at used to have  Oldsmobile. A GM special tool was a EVA (electronic vibration analyzer)  it worked on the same principle as the link Mr.Logic posted.  Excellent tool  I wish we still had it, when Olds went out we had to send back all special tools, parts ect.

Your friend at GM should have access to this, or maybe the dealer would sell the EVA  if they are made to switch to  Pico NVH tooling.

No I do not have access to one, but I find the discussion here on it enlightening.

It is great to consider the possibilities of where we can go, what we can do and what can be added to with our Picoscopes.

I find the discussion here a constant primer for my thoughts, I have you all to thank for that.

I did talk to Tom yesterday about the tool. He has them on the shelf and has sold a couple.

I asked if he had any feedback from his customers in regards to the tools performance and he said no.

He mention they have tried it a couple of times, but Andrew is the one who has used it the most.

Mike, I have heard the EVA works good. The issue is theirs is broken and they are trying to get a rush on the new one before their CSI goes in the drink.

Told him if they let me borrow the tool I will give them a basic class on the potential use of the Pico scope in return. The scope is just not for NVA.

This way they can purchase all the accessories from Tom and be able to broaden their horizon's

Ian, not to change up subject. Have you used the Pico on Flex Ray yet in the F series BMW's. If so, what is your experience?
