Hello!

I installed e85 fuel-box. The MPGuino did work before that, and during that.
I removed it, and then MPGuino does not display any info from injector.

I have several MPGuinos and all tested, so it can't be that.

At idle, the injector gives around 70Hz signal(Measured with Hz meter, i dont have oscilloscope).

I tried by adding some kind of lowpass-filter just to test what happens, 4k7 and 100n, and it brought some kind of signal to MPGuino, but it's very distracted.

Any thoughts what could be?
