What is the output signal range of a rev burner?

[ribfreak]

Hi Folks,

unfortunatly I can`t find any information about the output signal the rev burner is capable to generate?

Wouldn`t it be a great idea to pass such an important information on to the users? For example: My dash will need a 5Vss rectangular, frequency modulated signal for tach as well as speedo, for topspeed it has to be up to around 3.5khz.... if I´d have the output specifications it would be pretty easy for me to decide wether I can place an order for 2 rev burner units or not. Right now I can`t. I`m from Germany and I don`t want to order things from outside if I`m not 100% sure that I can make them work afterwards!

The whole forum here is full of questions like: "I can`t get the rev burner to work with my XYZ-dashboard!" so why not specifying clear and precise what output signals are possible? IMHO this would be a major step forward because a lot of people who are into simd are quite familiar with basic electronic knowledge.....

greets,

Hello.
Thank you for your suggestions.

I am sure somewhere in the website it is indicated that the signal output of the rev burner is a square wave at 12V, able to drive rev counter up to 17.000 RPM when the the rev counter is configured for 4 cylinder engines.

Regarding the speedometer, this page:

http://www.symprojects.com/using-the-rev-burner-with-a-speedometer/

contains some information regarding the signal and its frequency.
This information will be obsolete soon because the new version of SImDash will  make the rev burner able to output a signal with double the frequency. The new version is due for today or tomorrow.

If you have suggestions on other information I could add, I will be happy to do so.

Regards
Cristiano

Hello Cristiano,

thank you for your explantions. I`ve read the things you`ve mentioned already before I posted here, but still I don`t understand why you don`t want to specify the FREQUENCY range of the output signal?

It might be ok to state a certain rpm when we`d only consider a 4cyl engine but how does it perform when a speedsensor output needs to be simulated? In that case your arguments wouldn´t fit because there`s a lot of different speedsensors on the market- some work on the camshaft, others work on the sprocket of the gearcase (motorbike) and so on.....

It would be so easy if you just could state: 0 to 12Vss ranging from 0- XY kHz, so why do you make such a secret of it? I could even sit down and measure it, but like I said before: I won`t order and pay to find out lateron that it doesn`t work for my dash!

regards,
Wolfgang

Well, it's not a secret. SimDash even displays the frequency of the signal, in pulse per minute.

Anyway, the rev burner signal is at 12V, it's a square wave and the frequency varies from 0 to around 580 Hz.
Same think when the rev burner is using the firmware for the speedometer.
As I said with next version of SimDash, the firmware for the speedometer will create a signal with  a max frequency just above 1Khz.

I hope this helps.

Hi ribfreak

I was reading on the x-sim forum one of your comment saying "why re-inventing your wheel" or something close to. And you were talking about the availability on ffb controler to do your own wheel.

Did i read and understand right? if so can you help me find some.
