🙂 It's FWHP - and the car also has a rather good trick in its book... it can get 2.9 litres/100km. The retarder fan has been removed from my dyno. I'...

Now you've caught me. I was just thinking big on-screen on/off buttons! But when I think about it, one output could trigger a dyno brake cooling fan -...

Finished with top end. Now need to spend a lot of time from 4000 rpm downwards. Re dyno: will now build power supply into a proper box. Have bought th...

Well, I didn't expect to achieve that! 98RON pump fuel (previously tuned on 95) , more timing in top-end and from 2-4000 rpm. You can see that I lost ...

Ah yes, that's right. Anyway, it was quick and easy.

Yes, something different I'd imagine. For me, it doesn't matter - the dyno will so rarely see a different car that I could set the inertia value up fo...

Nice going Julian it's ALIVE!How are you going to correct the rotating asseblies moment of interia?Jostein has a good video on how to do that. Basica...

First complete runs - low and high boost (1 litre turbo... that doesn't breathe very well at higher revs). Not yet properly corrected for roller inert...

Found the webpage reference - checking now.

No I haven't! Where are the details on that plse?

Speed sensor working well. Have load cell calibrated. When controlling eddy current power supply manually, I can read power and torque figures. But......

Lots of mess. YourDyno software shows roller speed without any apparent glitches (at least at low speed - not yet put a car on it). Tomorrow I might t...

Pretty good waveform on scope:

I got YourDyno sensor mounted with original tooth wheel. Simple use of washers to change gap. I have gap pretty small!
