I broke a Bosch LSU 4.9 and I think Speeduino can help avoid that. I learned I need to power up the wideband controller only after the engine is running, otherwise it will get damaged. Bummer. I found this explanation:

So, I would like a delayed signal from the Speeduino to drive a relais. I know people use the fuel pump wiring, but that also starts before the engine runs. Would it be possible to use Speeduino 0.4 port 14 (proto area, I don't use a flex fuel sensor) to generate this signal, using the 'Programmable outputs' in TS? Never mind the chosen output pin number, but something like this pic
Using an unused port of the ULN2803 already there for the fuel pump relais and the fan relais?
Cheers,
Hugo
