Aquamist 3 issues

Hey folks! This is my first time on a forum so be nice 😁

I have recently fitted an aquamist 3 kit on to my naturally aspirated BMW 323i E36. - I have the intention to turbo the car, hence fitting the kit.

My issues are as follows:

I have a green IDC light in the control unit, however no light on the gauge.

When the car is revved the relay clicks constantly whilst water injection is engaged and the "B" light flickers with it too.

I have no red bars showing on my gauge whatsoever. - I have tested the gauge by moving the pin in the controller and it worked fine then.

When the water does inject, the water level light comes on momentarily after even though there is adequate water in the tank.

One note to mention is that when I bought the kit, annoyingly the cables (fav, water sensor, and tank water level) had been cut. All of which are correctly reconnected in accordance with the wiring diagram included with the kit. Perhaps the resistance of the cables could upset it?

I am eager to get the kit working so any advice or pointers would be super helpful! 😊

Re: Aquamist 3 issues

You may have reversed the two wires to the fuel injector

Re: Aquamist 3 issues

I did try reversing the cables just in case but it makes the whole guage flicker.. The IDC light is working okay in the control unit so I think they are the right way round.. I will double check tomorrow though ��

Re: Aquamist 3 issues

Can you tell me what version is the controller or serial number.

Re: Aquamist 3 issues

I've changed the wires over too and it just makes the relay click constantly and the 's' and 'b' flash...

Can you give me the serial number, there are some minor differences. On the v3.1 , they are all the same, for now.

There are 3- test points on the controller, do you have a digital voltage meter so you can help with the diagnostic work.

Re: Aquamist 3 issues

Yea I have a multimeter, I'll send you the serial number as soon as I'm back home �� Thanks :)

Re: Aquamist 3 issues

What is the serial number?

Re: Aquamist 3 issues

Sorry for the delay, I had trouble getting on here... The serial number is: 101286
