Well I finally finished the install on my DDS3 v.10
The v.10 is the newest version and offers some nice refinements.
In addition to installing a new dds3 kit, I also re-wires all the electronics in my car so that they get power and ground from a "universal rail". This way the ECU wires for power and ground are only tapped once. This also helps to eliminate any ground offsets to the electronic devices. Finally it makes working on and installing electronics in the future much easier. I used my old DDS3 v.8 junction board box to hold my little custom board for the power rails. I also including the circuitry for the alt map harness inside the old junction board case.
Here is the old case, old junction board, and new breadboard.
The little blue terminals act the same way as the screw terminals on the aquamist kits. Each side is connected as a separate rail. With the right being all power and the left all being ground.
Here is the new kit components. A new board, gauge, and a new flow sensor with user serviceable ends.
You will notice I also install a connector on the flow sensor, this is for easy service and replacement.
I wanted to use the existing circuitry on the new board for a test button. The board already has a jumper that you can short for a test. I used the connector of an old computer case to bridge this jumper and give me wires to connect to a momentary switch. I did have to drill a matching hole in the top of the case to fit the jumper.
New flow sensor installed in the wiper cowl.
All the wires installed in the new Junction Box
The box when closed
Finished, both boxes are Velcro mounted behind the glove box. All the wires are wrapped in spiral for the first 6 inches extending from the box. You want to leave enough slack in the wires to at least hold the box in you hand while sitting in the pass seat so you can tune it later.
I also used wire loom if the wires are run over a metal edge to make sure the wires are not stripped and shorted.
Summary -
It has been nearly a year since I drove my car on meth. I was out of the country for the first 6 months of this year, and then when I got back I worked on a couple other areas of the car before reinstalling the meth kit.
The car is now a little bit lighter and has a few more parts on it since I last drove it on meth. Anyway the result is simply ridiculous. I am running 31 psi on 100% meth and pump gas. It’s the first time in a while that I can remember the car being genuinely scary. From logs run through data log lab, I am guessing hp and tq to be at 450 and 470 respectively, in a car that weighs 3,000 with me in it. Flooring it in first gear is just silly, as soon as it spools the tires break loose and you are at redline. Amazingly enough, the same thing is pretty much true of second gear as well. In a completely straight line I can lay on the throttle at 3k once the turbo hits full boost, the tires spin like crazy and I am bouncing of the rev limiter. Third is the first gear where I have traction with full throttle in a straight line.
I never imagined traction to be a problem in a straight line with an AWD car. THANK YOU AQUAMIST AND THAT YOU RICHARD!!
