Hi Martin, Thank you for that.. I will try to look into it some time in the next days, no engine on dyno today

cheers.

Hi Steve, Well success to a point. I have tacho setup with 4 pulses per ENGINE cycle so 2 pulses per Rev. The data synchronises to a point.. The data tends to "float" a little across the screen. while the size of the channels requested remains (ie 1 engine cycle) the channel data tends to jump a lit...

Fantastic guys, thank you all. Steve my Crank signal is 60-2 so the frequency won't be constant and in any case I am using a motorsport ECU so I can simply configure a Tacho output. I would think that will be easier solution.

Hi Guys, thank you for your quick reply. Martyn, I guess the channel (A)in the formula is Input A so could be any of the inputs (B,C,D). I would also guess this input needs to be a frequency consistent to what I want to sync to, RPM in my case. If I use a Tacho output from the ECU this should be suf...

Hi all. Is it possible to link the traces to sync with engine RPM.. IE I am using an engine dyno and I want to display 2 cycles of the engine on the scope then when I increase the rpm the same data stays on the screen, so I guess you can say the time scale is linked to RPM to keep the same display.....
