Chapter 20: Trouble Shooting & FAQ’s
Trouble Shooting- Common Issues (cont.)
RPM intermittently drops out or PC ceases the test run prematurely
This can be from ignition interference, as covered in a previous FAQ, but do not overlook the PC itself as another issue.
We have encountered particular laptops that will not run reliably near engines. Wireless attachments can give trouble
also near interference fields.
Do not have any other programs running when DYNerti3 is operating and make sure virus programs are not inhibiting
operation. If in any doubt, and after you have taken the advice in the hardware setup chapter regarding avoiding
interference then please try another PC to test.
Test results seem good until high RPM, then erratic power readings.
If RPM is coming from the engine ignition system (RPM Adapter input being used) then at high RPM the rev limiter may
be cutting in and killing the ignition pulse. Avoid using the RPM Adapter input as the primary RPM source, just use it for
‘teaching’ the ratio (see ‘RPM Input options’ chapter in this manual)
Certain vehicles/engines coming up with error warnings when processing the data after a test run.
Make sure the start and finish speeds are reasonably set in the ‘Record Settings’ field on the Dyno screen. Ignition
interference with the transmitted USB data is the next likely cause. Test the RPM input by observing the gauge operation
(press the ‘Gauge’ button and run the engine)
-Use suppressed ignition leads and resistive plugs for the testing and ensure all wiring is as far as possible from the
interference source.
‘Double Click’ in other programs running (i.e. not DYNertia3) does not work.
You were told not to run other programs in the ‘Software installation’ guide! Close DYNertia3 and function will return.
‘Run Time’ error occurs and DYNeria3 will not start.
Copy the ‘DYNertia3.D3CF’ file (‘C/DYNertia3’ by default) and email it to us with fault description. Delete the file
(DYNertia3 will recreate it) and re-start. You will need to re-enter your settings (SETTINGS.txt file has them).
Screen text appears to be out of place, the wrong size and DYNertia3 screen seems to be all ‘messed up’.
Windows has been set to the wrong display properties (its magnifying the text so it won’t
fit on the screen).
Depending on what version windows you have you will need to search and find the
‘appearance and personalisation’ and then ‘display’ settings.
Throttle servo is ‘twitching’
See chapter on Load Controller for notes on filtering and setting speed of operation. Some servos are very sensitive to
electrical interference and will require small ‘bypass’ capacitors (e.g. 0.1uF) to be wired directly at the servo. Isolating he
servo from the engine via a nonconductive ‘pull cable’ will help also.
