"Injector test" (Expanded functions for Test PWM)

[Davidv]

I've finally started piecing together my injector test bench.

I want to test:

-Injector deadtime at varying pressures and voltages

-CC rating / see how well injectors compare in a set

-Spray pattern at varying fuel pressures

So putting something together to physically acheive that is fine, I want my ECU to run it and datalog it though. 

What's the best way that I can control the injector with the ECU while the engine isnt running?

If I use Aux injection with a 1d table for a value at 0rpm, will that do anything? Or because it's 0rpm, will it only fire once/never.

The "PWM test" would be good but it only lets you specifiy the HZ with no control over pulsewidth etc.

It sounds like Aux injection can acheive everything I want, so long as it's able to work at 0rpm.

If there's currently no way to control the above, then could I please add to the wish list:

"Injector Test" function for aux outputs (Or just expanded test PWM function)

-Can specify HZ, but also ms opening time or % opening time

-Run the test for a certain number of events or for a certain time period. (Run for a minute, or run for say 500 events)

-Switchable on/off by a DI / virtual aux /  timer

-Able to datalog the above

Thanks,

David

Check out the options on the injection test for injector drive 1.

Think this will have you covered.

Haha wow!

That's perfect... How did I miss that.

Thanks Simon.

Hi I've  probably found a bug

The Advanced Injector 1 Test function doesn't work right if injection mode is set to off. It injects alot of fuel and the test doesn't stop. 

If i set injection mode to sequential and configure the injection outputs, it works fine. 

Please have a look.

Hi mapper,

Thanks for letting us know. I've been able to re-create the problem and have passed it on to the engineering team.
