Good day!

My mechanic is going to install today the Zeitronix Wideband controller. Zeitronix has 1 user input(0-5volts) aside from the other predefined inputs and outputs. I would like to know if the Zeitronix would accept in the User Input the signal coming from the speedometer to login the speed.

Thanks!

smart idea!
truly I don`t know the speed signal voltage.
Remember that you can use the other inputs too
and calibrate them in the software.

Maybe you can tell us later where you take the rpm signal from,
a friend has ongoing problems with that.

thanks

Speed sensor is a frequency input, not a 0-5 linear.

What are you currently planning on monitoring?

Falk930, I'll let you know when I get my car from the shop.

Dwalker, I'm planning to monitor AFR, EGT, boost, rpm and hopefully speed. So it is not possible then with zeitronix?

A much more useful set of parameters to monitor might be Intake Air Temp, RPM, Boost Pressure, AFR, and Fuel Pressure. EGT is nice to monitor in a diesel or a steady state application such as aircraft or marine engines, but auto engines, especially boosted engines, are far too dynamic for most EGTs to effectively monitor. By the time you show a problem, the damage is done due to the slow reaction time. Also,EGT without other information can be very misleading and worse than uselsss information. Intake Air temp is IMHO very critical to understanding whats doing on in the engine, as is fuel pressure. Please feel free to give me a ring if you would like to discuss further, as well as looking at this article on my website: http://hrd-performance.com/13.html which might give a bit more insite into the hows and whys.
