5v senders

[skylinegtrhr]

So did you manage to test these sensors?

[STATUS]

they look like std GM sensors we use them also. lsx engines have them from factory, great for logging at a cheap price

Thanks for direction , can you share a link where you get them? We in Europe don+t have "real" GM only Opel with really sh... sensors made in China or Eastern Europe ...

Been a bit busy on other projects. Car was a daily for a bit there.

I got that fuel sensor for the ebay link provided.

The G sensor i think came from here https://store.arduino.cc/product/T000060 as i bought an arduino for my testing bench purposes.

I have had a few delays but have put the yellow wire out of my LC-1 to my DLP and that is running well.

I will over time make a working AIT pre and post cooler and that will pretty much cover my needs.

Updates on the fuel sensor next week i think.

well it wasnt a week but I got an aem 30-4401 it outputs 5v pretty well.

When I was using the DLP 5v output I got complete garbage. I am guessing it was unable to regulate the voltage.

I will test this with a stable 5v buck boost conveter one day.

I can monitor the fuel pressure now and I am thinking I will send this through an arduino to create some alarms.

The next thing is I want to log solenoid performance from my transmission. Maybe also manifold pressure/temperature with something like this

The thing is I get strange readings on all the other chanels when aux 2 is plugged in.

Currently nothing is plugged into aux 1 but it seems to be getting interference

You need to ground (or use a weak pull down resistor) on any unused inputs, otherwise they flap to noise, and can also affect neighbouring channels too

Another option for 5V is a LM7805 regulator (google as there are various ones around)
