Keep up to date on the latest developments at Howerton Engineering and Aquamist.
This last weekend a Howerton/HFS-4 equipped car set the record for a CTS-V in the Mile at 192.6mph. This car is equipped with our new 2.5 gallon baffled and sumped tank and an Aquamist HFS-4 injection system. If you need a setup that’s going to work the best for your V, don’t hesitate to call us.
Here’s a few pictures of the setup.
We are currently working on a system for a E60 535. If you in the Northern California area and would be willing to bring your car by for some measurements please contact us. Thanks.
We will be receiving a batch of HFS-4 boards next week for the upgrade program to begin. Once we begin shipping, there will be one week to get your name in on the upgrade then it’s closed. We may not have everything shipped in that week, but we will cease to take new names.
I will make one final post when the shipping begins with the cutoff date.
As for those than are signed up. I will send a PM when we have the boards in hand, or you can send me an email with HFS-4 Upgrade in the title and we can get the payment and shipping arrangements setup.

HFS-3 to HFS-4 UPGRADE: Preliminary Info (Subject to change): We have some details for those wanting to upgrade their HFS-3 controller to a HFS-4. If your HFS-3 kit was purchased after Dec 1st 2011, the upgrade will be $50 with exchange of your existing controller. If the unit was purchased between Jan 1st 2011 and Nov 30th 2011, the cost will be $150 on exchange. After the HFS-4 GB ends, we will post up the procedure for the exchange process, this offer will most likely be limited to a 30 day window.
We received our test units today. We have the our local 335 test car coming by in the morning. It will be a fun day….
Below are preliminary schematics for hookup to the standard ECU and 3rd party controllers. We will be bringing our local test car in this week to test the wiring arrangement.
You can see the new HPFP signal tap for the HFS-4 controller.
The group buy will be held on the Aquamist forum at waterinjection.info If not a member already, you will need to register. Scroll down to the HFS-4 sub forum, and be ready to put your name on the list when it opens.
Group Buy is OPEN!
The HFS-4 is officially here. We have preliminary product information, and this kit is hot. Many of the improvements are of a big benefit to both regular and Direct Injection applications. The main changes are new inputs and tuning functions to tailor the injection to the application, whatever in may be.
Here’s a look at the first customer pics we have received back from an install. You can see the unit drops in and uses the existing fasteners to be secured. All of the stock trays and carpet still fit over the unit for an unobtrusive look.
We will be putting a standard package together in the online store with an HFS-3, appropriate jetting for the most popular SC kits, and the tank unit.
