I tried to test out my Speeduino at the weekend.
I assembled it myself last Autumn... and made some mistakes - I put one of the ICs where the VR conditioner was meant to go and when I fixed that I put the VR conditioner on upside down.
I fixed them both, but it involved desoldering which messed up some pcb tracks and caused further fixes so I wasn't that confident.
First test... It connected to Tuner Studio on my desk OK.
The MAP reported 105kpa which is reasonable and suggests the board is basically alive.
Next step was to connect it to the crank sensor on my running engine and see if I could detect it moving.
I couldn't. [emoji22]
My hope is just the VR conditioner is knackered.
So I've ordered a new one.
If that doesn't fix it, I think I have to make another main board and try again.
