CHECK IT OUT
sorrry but i dont believe it, i doubt 20 hp, it might do something coz i know advancing ur timing does give u some power....
wat u guys think? $5, its not much!

Rep Power: 0 for five bucks and a 10 sec install its worth a try. plus you can probubly sell it to a stupid riceboy at your school for about 30 and convince him he can feel the power. if they can feel decals HP then they can definatley feel this awsome ENGINE EDU MOD's HP. anyway. i like at the bottom how it says use premium gas for best results. PISH. yea right. i'm not paying for premium.[IMG]i/expressions/laugh2.gif[/IMG]. eh well.
think about it tho. if HP was that easy this would have been out and be in everyoens car.

Rep Power: 0 It just tricks the engine into thinking its getting more air than it seems and makes it run very lean. It's gonna kill your catalytic converter in the long run and who knows what else. I wouldnt even bother with it unless that guy's supposed liftime guarantee covers buying you a new cat b/c of his shoddy rip-off product.

Moron. It's very easy. This resistor would not affect engine timing, it only affects the signal going to the ECM from the MAP (manifold air pressure) sensor. It's a very cheap and ineffective version of the S-AFC, and I guarantee it would throw check engine lights all the time.

Rep Power: 0 Take a look of the fellowing web-site. It's not for our car but it will explain how that mod works. I am sure you can DIY for cheaper than $5.

thats the biggest load of crap i ever read, you can't advance the timing just by adding a chip, wtf?!!? Timing is a mechanical thing meaning you have to adjust seomthign physically not electrically. I wish I could take that guy out to a parking lot and just beat the crap out of him with like a big metal rod.

Rep Power: 0 Ok I know exactly what that mod is. It's a resistor you put into your O2 sensor at your intake. It basically tricks your ECU into thinking there's more air coming in then there actually is. Basically it's just a trick. And yes over time it screws up your engine badly. Just search around the net and you'll find info on it. I considered buying one until I did a little more research. They say it's supposed to do the same as the S-AFC and/or a performance mod. But frankly I'd rather spend the extra money on a quality researched part like the S-aFC or the Jet chip.

BTW: Did I mention that limiting the early ignition timing advance is one of the things they did to get cars to run on low octane "regular" gas?
If you look at the idea of fooling the computer by adding resistance to the temp sensor, you might also see that is one of the advantages of a CAI. The CAI is actually doing what the resistor is telling the computer, it's actually giving colder air. Colder are is not only denser, it's also going to allow more timing advance. A double whammy so to speak.

Well now, it's the ECU that controls the timing. You know about knock sensors and all that don't you? Like if a pre-ignition conditon is sensed, the ECU retards the timing to prevent knocking. One way of getting better fuel mileage and lower emissions is by not allowing for too much initial advance. If you have something electronic that will fool the ECU, then you might get more timig advance, ergo, better acceleration. That's been a mainstay of hot rodding cars for many years, well before the computer controls. Now we're taling about ignition timing, not cam or valve timing here. Is that what threw you off?

Now i'm confused. I have a cam gear which adjust cam timing, this is a mechanical thing that you have to adjust manually not on the ECU.... Now you start talking about the ECU controlling timing? I'm confussed here, are you talking about the ignition timing? Our cars don't have a distrubutor so how do you adjust the ignition timing on our cars???

Please read the post again. I believe all the info you are asking about is there. Look for the key words "ignition" and "timing" and the phrase "ignition timing".

Rep Power: 0 OK my bad I meant IAT sensor but regardless the mod is a ressistor that you basically bridge the IAT sensor with and then leave it unplugged. Main point of my post is it's a mod that will do serious damage over time, and that time seems not to be too long. If you really want to try it I can give you the type of ressistor you need when I get home and you'll save yourself 5 bucks or 20. Just pm me if you want it.

OK I reread, I must have missed that part before! So what you are sayin is the ECU maintains the proper ignition timing automatically??? Like If I adjust my cam gear do I have to adjust the ignition timing or will the ECU automatically compensate? I know with a distrubutor the ignition timing can be adjusted from there I think, but with our cars do we have to even worry about adjusting the ignition timing? If so do you know how?

I believe the ECU will adjust ignition timing, but it will be limited. I think to allow more adjustment it will take a computer change or a unit that will again fool the ECU such as a Venom 400.
Here's a link to a thread about the Venom. I see you posted there that you have one, so you should be all set for it to work with your cam gear.

Rep Power: 0 I pulled the temperature sensor out and did a simple test on it. I connected it to an ohmmeter on the two metal pins of the sensor. I got 470 ohms at 100c (boiling water) and 5700 ohms at 0c (ice). The range is about 5k diff. for 100 degree. Let say connect a 1 or 2k ohms resistor in serious sounds reasonable for the mod. I am trying 3k ohms on my EX and it works fine so far with 93-octane gas (no ping and very good acceleration). Try it at your own risk.[IMG]i/expressions/face-icon-small-smile.gif[/IMG]

Rep Power: 0 I'm thinking that you could buy a extra air temp sensor (About $21) and set it up with a resistor and then you could switch back and forth from stock to mod, etc.
Also I believe the engine will run richer, not leaner if it thinks the air is colder. Remember when cars had a choke, so they would run when it was real cold? That choke simply cut off part of the air to the carb.

Rep Power: 0 Our car has an intake air pre-heater instead of the old style that required a second hose for exhaust heating. But anyway, a secondary sensor is a good idea but a carefully selected resistor will be cheaper (5 cents and some soldering). I did not modify the sensor itself, but put a resistor in series to one of the wires connected to it. If you really want to replace the sensor, I think you need a larger range of sensor (e.g. -25c to +120c not just 0 to 100c) with the proper range of resistance. Good luck.[IMG]i/expressions/face-icon-small-smile.gif[/IMG]

Rep Power: 0 The throttle body heater has a closed loop where engine coolant circulates, but that is down lower on the throttle body. One guy posted a thread where he bypassed that part around the TB. There may be a sensor in there too as there is a wire to it.
As for the new sensor, I was thinking of using the OEM sensor from one of the Honda parts places, then attaching that to a quick connect plug. That way you could switch back and forth to stok or one with resistor easily.
The point about the resistance range is this. If we know the actual chart for the temperature sensor, then we know exactly how much resistance put inline will synthesize exactly what "temperature" the ECU is seeing.

Rep Power: 0 All right, now the question is at what lowest temperature will get the most advanced timing. Also, at what temperature will trigger the pre-heater. So we can get to most out of it and avoid damage on our car.

Rep Power: 0 I know that mine runs best for the first few miles, and part throttle when started from "cold" at an ambient temp of 70F. Of course maybe need to factor in humidity, etc, but that temp seems to have more power at moderate throttle.
