### September 2019

 This edition… …we have a guest case study written by Martin Jensen, which goes into detail on how he diagnosed a vibration problem on a Lexus. Our video and article series PicoScope NVH and Maths is cool continue. Our team has worked hard to update and complete Guided tests and their videos, and we now have another four videos available to watch. Our "Best of the web" section features an article and some popular videos featuring PicoScope and this is your last chance to sign up to our amazing giveaway competition where you can win a WPS500X kit.  Like what you see? Why not forward it to a friend?

Lexus GS 300 | Driveline vibration problem
By Martin Jensen

My customer bought the car 6 months previously. During the initial test drive, he noticed a slight driveline vibration. The salesman told him it came from the tires. The car got four new tires matched with rims, balanced and road force tested. But the car still had a driveline vibration.

Steve Smith and Frank Massey discuss the road test results end how you can use the tools to analyze the different areas.

We are releasing another batch of new Guided test videos:

 GT008 Air flow meter – air vane The purpose of this test is to evaluate the voltage output from the internal track of the air flow meter during engine idle, Wide Open Throttle (WOT) and over-run conditions. GT009 Air flow meter – hot film –turbo diesel The purpose of this test is to evaluate a hot film Air Flow Meter's (AFM) voltage output with a turbo-diesel engine during engine idle, acceleration and over-run conditions. GT017 Multi-point injection injector current The purpose of this test is to evaluate the operation of a multi-point port injector based on current flow, response, and formation during engine-run conditions. GT036 Crankshaft position sensor inductive, referenced, voltage during cranking The purpose of this test is to evaluate a Crankshaft Position (CKP) sensor’s inductive, referenced, output voltage during engine cranking.

Maths is cool - Part 9
By Steve Smith

I thought it would be good to revisit the maths and modify the technique to calculate the theoretical MAF.

Here we have a 1.8-litre, 4-cylinder, normally aspirated Toyota Celica…
