I'm getting an engineering degree.

1NZ is correct they are principally a diode that tricks the ECU. However will not trick ours? Garm I'd say open it and take pictures for me but then no refund. Honestly I think this one is just a loop that goes into place maintaining the circuit without doing a damn thing.

Sorry but it wouldn't make it through Custom's

ztrack157 · 12-20-2008, 02:02 AM

Oh yes it would! lol just put bear scat in to scare the dogs.

superfly78209 · 12-20-2008, 02:08 AM

wow this is awesome.. cali keep us updated.

cali yaris · 12-20-2008, 02:22 AM

hehe, alright - let's settle this. And I don't care about returning it, I'm opening the thing up after I play with it.

We require photo proof ,

when it arrives and apart

until then

ztrack157 · 12-20-2008, 02:29 AM

Ok sweet Garm is the man after all. Even though hes a vendor he needs moderator status he is a guru.

richardholdener · 12-20-2008, 02:53 AM

Hows this for an offer-you get your car and this magic product to either of the dynos (here in Vegas or in palmdale0 and I will test this for free. We can monitor the air/fuel and timing values before and after and see what it does-if anything. That way there is no speculation. I don't want to hear it felt better-I want real data. Let me know Cali.

You the man ,here's your chance Garm ,to dyno you beast

ztrack157 · 12-20-2008, 03:21 AM

Thanks Richard. Let the myth be cracked. Now if you'd only sell me one of the prototype intakes. :)

mikenacarato · 12-20-2008, 04:18 AM

you want a placebo to take with this too? these modules are all bs..every last one of them (not talking about real engine management systems and such though)

and please spare me the "oh and you know this from experience?" part. i DO know from experience.

Loren · 12-20-2008, 11:21 AM

There is no "circuit", it's just a resistor in a fancy box. It is installed inline with the intake air temp sensor and causes the ECU to read the temperature as lower than actual. Since cooler air is more dense, this makes the ECU "see" that more air has gone into the cylinder and it injects more fuel. A slightly richer mixture can give more power under some circumstances. But, this only happens at full-throttle or during warm-up when the ECU is not in closed-loop operation. In closed loop, O2 sensor feedback will correct the error induced by the faulty temp data.

So, it "might" give you slightly more power when you get on it, but there's no way it's going to improve fuel economy.

That's all there is to it.

richardholdener · 12-20-2008, 01:08 PM

Altering the IAT value to show colder inlet air temp can also increase ignition timing.

Good point, Richard.
