From the WTF Files

31 Jul

Someone on a local forum we are a sponsor on was asking for the wiring diagram for the Inlet Air Temp. Sensor the other day on a G35. When asked what he needed it for (sort of a random wire to be splicing, and you figure if you’re doing a mod that involves splicing that wire (such as converting from MAF to MAP, you would own a factory service manual already..I don’t know, call me crazy), he replied that he was helping a friend install this:

triphase

The manufacturer claims gains up to 20 hp and 15 lbs of torque just by wiring this little device in. I don’t know about you, but it looks like something that Realistic made (exclusively for Radio Shack) circa 1985.

So what is this thing really? It’s a little metal box with resistors in it, that’s what. The resistors intercept the air inlet temperature sensor signal to the ecu, and “fool” it into thinking the air is colder than it really is. Colder air (even though in this case, it’s fake colder air) = more timing advance on many ecu’s, and viola, you get the “feeling” your car is making hp. You have 3 modes to choose from – street, race (give me a fucking break), and “off” – hence the tri phase.

I’ve heard Motec, Pectel and Pi Research/Cosworth each have their own versions being shown at SEMA.

Do yourself a favor – save your money. Or if you really have $180 burning a hole in your pocket – donate it to your favorite charity, take your girl out for a nice dinner, or maybe go get some lapdances.

Project Z33 Continues

4 Feb

Some more new stuff arrived today for my car.  Thank god there is snow on the ground – gives me time to get all this stuff operational!  This new toy is going to be a bit of a chore to install and setup exactly like I want it, but I’m really looking forward to the final result.

I posted about this about a month or so ago.  It really is an amazing piece of equipment and the potential is simply awesome.  Since my car is used primarily for street, I opted for the standard display only model.  There is another version that datalogs, and it’s possibilities are nearly limitless.  You could moniter shock travel, clutch slip, etc etc.  But that’s a bit over the top for my needs, so this will do.  This will connect to my Haltech 350Z Platinum ecu via the supplied plug and play cable, and I will set it up to display rpm, speed, fuel level, afr, oil temperature, coolant temp, and odometer.  However, through the CAN network, it can pass through all sorts of info such as fuel pressure, fuel trim, TPS – basically anything that is part of the OBD2!  Really slick piece, and at $700, it sure beats having a ton of different gauges scattered throughout the car.    Next thing to do is getting it to my installer guru Dave, so he can fabricate me a proper housing to make this thing look like it came with the car!
