Independant MAP sensor to run DDS3v8
 

Can I trigger and run a dds3v8 off a 3bar map sensor that gets a switched 12v signal cut to 5v (using a 7805 voltage regulator) ?
The 3 bar map sensor would only operate the aquamist/hydramist.

The MAP sensor can only trigger the system but the system still mirrors IDC. The 7805 voltage regulator will be perfect.

OK, well can I use the HFS-1 generic wiring diagram (page 8) http://www.aquamist.co.uk/forum/gall...FS-1web-sr.pdf to run the Hydramist.

The injector pin-out is here on page 26 and 27

Cant believe I forgot the link:

Page 26 and page 27?

You can send an PWM signal out from the hydramist to run the MSV (medium speed valve) valve and trigger the DDS3V8. Unfortunately the HFS-1 valve will not be fast enough deal with the 80Hz frequency of the Hydramist.

In case you are thinking of replacing the MSV with FAV, don't. This is because the hydra's output current is not capable of driving the FAV directly.

Added the link to my last post.

I have the Element Hydramist kit with HSV and flow sensor, what I meant was can I just use injector signal taken at the wire harness/ecu and connect to pinouts 17 and 23 of the dds3 v8 box. as indicated on page 8 (generic wiring diagram) of the HFS1 instructions.
