I have just put together one of these Jaycar FCD kits and would just like to know are they safe and reliable to use? Also is it possible to connect this up to the map sensor under the bonnet instead of directly to the ECU?
As far as i know, when put together accurately, they are quite an awesome unit.
I know, I had one If your tuner is pretty on to it, they are capable of tuning it as well, kinda like the apexi safc floating around. This has been discussed before so they are a few threads around.
Don't know about your second question though, I guess in theory it all goes back to the Ecu

Any water or moisture will possible affect the unti at some stage under the hood. Also the intense underbonnet heat wont help with its life span, depending on the solder work and also the temp thresh hold of the casing.
Much easier to install it with the ecu

I've built a few of these and they are currently residing in cars with engines worth substantiallly more than the average 1J, so if its good enough for them... I've had no complaints as yet, and they have been running them for well over a year now.

They aren't adjustable out of the box, but if you replace the 10k resistor that is located just after the map sensor input on the board with a 10k pot (adjustable) resistor this makes it possible, then you just gotta adjust it with a multimeter until it makes around 4.25-4.3V at the output side of the circuit

Sorry my bad, I worked it out wrong and it was still clamping at 3.9V on mine until I changed the 3.9K resistor to a 4.3K and the 680ohm resistor just before output to ECU needs to change to a 300ohm
