    Personally I find the excessive speedo inaccuracy in this country bloody frustrating. We all know our speedos read way under, then it’s up to us to determine what is actually 100kmh. Get it wrong and bingo you’re paying fines.

    FFS just give us accurate speedos from factory then if we modify the vehicle the fault is ours. Can’t be that hard.

    Just had a look at that and in a nutshell I think it says a speedo shall not read a speed less than the true speed of the vehicle, and at 100kmh should not read more than 4.4 kmh above 100kmh.

    If my interpretation of Clause 5.3 is correct of course. Or have I got that back-to-front? I've had had a couple!

    Not true by my calculations.
    Using that rule, with your true speed at 100KPH your speedo can read anything from 100 to 114KPH (basically 10% +4KPH) and comply with the ADR.
    Or put another way: with your speedo reading 100KPH your true speed could be anywhere from 87.3 to 100KPH.

    Happy to be corrected mate. That’s crazy isn’t it? Really shouldn’t be that variance in factory spec cars.

    I have ordered a HP Tuners MPVI3 dongle which will hopefully arrive on Friday. Pearl will be my daily driver for the next 3 weeks so I will do some dataloging and post progress here and on YouTube, like a tutorial, so others can try it if they feel brave enough. Initially going to use VCM Suite and possibly Race Render on my Panasonic CF-31 Toughbook until I get, and it could take a long time, a newer FZ-40 Toughbook or a Toughbook tablet.

    Holy smokes mate, what is it about your daily driving that others may need bravery to try it? And the FZ-40 Toughbook that you aspire to is military standard fully IP66 rated laptop hardware. Would love to read all about your daily drive.

    I've been tuning cars for years and was able to get into it because someone taught me how to do it. I live in NSW they live in WA and they could show me how to do it. Tuning EFI cars is not like tuning carby cars that can be quite forgiving. Get something wrong tuning an EFI car, especially modern EFI, and you can brick the ECU and a myriad of other high tech componentry so many people are turned off trying it for themselves because they don't know how to do it and are wary of trying it.

    I have a few Toughbooks and I use them because it is the fav computer in the automotive industry. I have CF-29s, CF-30, CF-31, and a CF-D1. There are some FZ-40 units on 2nd hand markets now but prices are still high. Prices will drop when more come on the 2nd hand market and availability increases.

    My daily drive is boring. Home to work, work to home in the glorious NSW Hunter Valley The exciting thing to be looking for is the datalogues.
