Paddy Posted April 28, 2020 Report Share Posted April 28, 2020 Hi, I am installing a Thunder into a 350z and i need to test that a few of the can outputs are working. For most i can simulate these by wiring the sensor to inputs then moving it, or by using a trimpot, but i was wondering if anyone knew a way to simulate the RPM input? Is there a way to force an RPM signal onto the pre-configured 350z CANBUS settings to test the gauge cluster? Any help would be great!

Adamw Posted April 28, 2020 Report Share Posted April 28, 2020 You can connect a loop wire from an aux to trigger 1 pin. Set the trigger mode as below. Set the aux to test PWM and changing the frequency will give you different RPM. Davidv 1 Quote Link to comment Share on other sites More sharing options...
Paddy Posted April 29, 2020 Author Report Share Posted April 29, 2020 Awesome! The aux test PWM cant go above 300Hz, to simulate higher rpm, should i change the tooth count on the trigger setup? Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 29, 2020 Report Share Posted April 29, 2020 Aux 1-4 can do 4000Hz. 300Hz should be 3000RPM on a 6 cylinder if I have that right in my mind? You cant change number of teeth in 1 tooth/TDC mode but you could change the number of cylinders to something smaller. Quote Link to comment Share on other sites More sharing options...
Paddy Posted April 29, 2020 Author Report Share Posted April 29, 2020 Ok, got it working! thank a lot! FYI on these settings 300Hz ended up being 6000 rpm Quote Link to comment Share on other sites More sharing options...

Paddy Posted April 30, 2020 Author Report Share Posted April 30, 2020 Now that i can simulate RPM, Can I simulate the fuel consumption to check that on the dash also? Is it possible to select injector testing etc to simulate a fuel flow? Thanks Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 30, 2020 Report Share Posted April 30, 2020 As long as there is MAP and RPM and no fuel cuts active then the ECU will be sending out fuel consumption (vol per unit time), but I suspect the dash probably needs at least speed from the ABS and possibly other variables before it will be able to calculate fuel consumption per unit distance.

Paddy Posted April 30, 2020 Author Report Share Posted April 30, 2020 Good point, ill see if it works. Thanks again for the tips Quote Link to comment Share on other sites More sharing options...
