#1 Road Dyno Settings - help needed

Post by ysmalkie » Sun May 02, 2021 7:24 pm

I bought a Road Dyno and I am excited to try it out, however I need to understand how to move it to "coil Mode" form ECU mode.

The Instructions say:
The Road Dyno can to be configured to coil mode, by connecting the Dyno to a PC and using the Road Dyno
Processor software (rdp.exe) to set the higher number of pulses per rev. This is done by establishing a link to the Dyno and selecting Config under the Edit menu. Follow the instructions there. This will re-program the Dyno to "coil" mode. Note that you will need to re-program the unit to go back to clamp or ECU mode. You don't have to do this step; if the Dyno isn't programmed to coil mode you can correct the excess count using the "Sparks/Rev" setting in Road Dyno. The difference is that the Dyno unit's memory will fill quicker if you don't tell it to count less pulses! As the memory lasts about 4 minutes this may not be a problem!


Where is this setting of higher number of pulses per rev ??

The Config menu only has these settings:

Also, what did you set for::
- Spark/rev setting
- Drag Coeff
- Frontal Area
- drive terrain loss
??

I don’t know the answer to configuring between coil and ECU. Mine was already in coil mode, and seemed to work ok with that.

Here are the settings I used (S2 FHC). I’m not sure if they’re right or not. Adjusting the settings even a small amount has a bigger affect on the performance figures than one would expect to see from any engine modification, so there’s a temptation to adjust them to get the answer you want to see.
