Aquamist HFS Methanol Injection Systems
With the group buy going right now I think it would be a good idea to start a thread specific to the Aquamist HFS water/methanol injection systems.
This thread can cover all the systems, HFS-2, HFS-3 and the HFS-4, but please since the R53 and R56 (R55, R57, R58, R59, R60, R61) motors are so different let’s keep this thread limited to the N14 and N18 motors.
It would be nice to collect various system settings such as:
1.) Jet size
2.) Restrictor size
3.) System flow when is SYS mode
4.) Water/Meth mix
For the other settings (THRES, GAIN, etc.) I think it’s easiest to take a picture of the control board.
Another important item is if your car is tuned, is it tuned for methanol and approximate horsepower.
Eventually maybe we can use this data to determine the optimal settings for various configurations.
Also please free to discuss the installation process.

That's what I was thinking about doing. I was hoping maybe some one found a boost gauge that matches. I was looking for one that matched the rest of the gauges. Old school Autometer gauges look like they might be close.
I still am working on getting my boost issue figured out. I've made improvements, I was only boosting 10 psi now after some throwing parts at it I'm up to 15. I have the stage 3 tune from Battle and it should be about 20 psi. Its all on hold for the moment waiting on some exhaust parts.

Ordered mine today as well. I went with this gauge holder.

I installed my HSF-4 last weekend and everything went well. Not really sure about all the adjustments that are available so we left everything to factory defaults. We did adjust the system so it activates @ 12lbs of boost. I'm not sure about the whole restrictor thing though.

Oh I think it can be turned up all the way from a timing and knock point of view BUT you'll be running a lot higher boost. The other day with the JB+ at 50% I saw ~17.1psi. I'd imagine it could be pushing the 22psi limit at 100% and I'm not really excited about running that high of boost.

Here's data log that I did this evening. The main part of the boost lasted about 3 seconds. It gives an idea of how the temp sensor responds. There is probably some data logging lag.
I'm using the MAP PID because for some reason when I use the calc.boost PID it slows down the sampling rate to ~2 per second. Here I'm getting about 4 per second, still slow but I trying to see if I can speed that up (it might be intrinsic to the car)

I do have an automatic and I'm not sure how the fabled "over boost" works or how it is triggered. I'm not sure if it is triggered by the kickdown button or what. I usually never push the petal that hard to trigger it.
Today I was monitoring throttle position and was only getting 85% when the pedal was pushed to the floor but not hard enough to push in the kickdown.

I'm going to be tuned for meth on May 3rd by Manic so I'll let everyone know how that goes.
Where does everyone place their nozzle? I've been playing around with the idea of doing a dual nozzle set up where a .5mm nozzle is placed before the iat sensor and the second one directly on the intake manifold. What are people's thoughts with this kind of setup? Since the intake manifold looks symmetrical I don't think one cylinder will get too much meth than the others. I would run 100% meth on this setup. What are your thoughts?
