MoTeC Global Forum

Hi guys,

Has anyone built an ECU test rig for testing ECUs and sensors? I'm looking to build one and am looking for recommendations for a bench top PSU.

JR

Anyone? How abt the MoTeC guys?

we do have ECU simulators in house. Please Email directly to us with a detailed description of what you are trying to achieve so that we can see if we have something suitable.

regards

Has anyone successfully used an arduino to output a rpm signal for an ecu simulator ?
Looking to do this for my own test rig I'm building .

Google autosim

He is also in the process of making some other more specific units like crank signal generators etc.

Google autosim

Yes but I don't need to spend $1500 just to generate an rpm signal.

Surely someone has used an Arduino to output a basic rpm signal to use before, anyone got some code they would like to share for it ?

No you dont, but the thread starter never asked for that. He asked for an ecu test rig or simulator and Autosim is exactly that.

The same chap also makes and supplies these which are cheaper, but yes still a few hundred dollars

Google TF Electronics

And depending on what you class as an rpm signal ( baring in mind the variety of trigger patterns out there ), I have a very basic USB Scope with a signal generator that cost only £120

Or I have an old Gunsons sensor simulator that cost less than half that which can output pulse signals ( although dont think they make it anymore )

I recently got myself a "jimstim" and find it to be a really helpful tool. Has pretty much all common ref/sync signals built in but also allows you to design a custom trigger pattern if needed and will also simulate any other sensors that you can think of at the same time, TPS, temps, 0-5v etc...
I think it was about USD80 for the fully assebled version that I got but you can get the DIY kit version cheaper.

That looks pretty cool. I assume it needs attached to a laptop to choose all the different patterns ?

No you dont need it connected, the "wheel pattern" is selected via dip switches. It may be easier to configure when connected to a pc but I havent needed to try yet - I mostly work with 36-1.
