So its really THAT easy, huh?

Someone PLEASE exlain this and why it does/doesn't work..

I dont know to much about chips but I know in many other cars, chips can give a good deal of HP. Hondas I have heard dont usually get that much from chips, but the whole converstion was not about the S, so it could be diffrent with the S. To answer you question chips can provide extra HP. But for that auction you have to relize if he is not already stretching the truth, he is right on the edge. That 20 hp increase is prolly at the crank to so you wont feel 20 extra hp it at the wheels. (Its kinda like all the intake companies say 15 more hp, but in reality you USUALLY get like 5 at most at the wheels.)

 

It doesn't work because I say so. There. I just saved you .01!

 

Some of the RSX guys went and tried this out. Basically the idea is that it tricks your car in to thinking the intake air is cooler. It seems to only be useful in VERY warm weather. A few members reported less bogging when it was 90-100 outside.

Basically, don't waste your money.

 

This is just a stupid BS deal. It is just a resistor that you put on one of the sensors. It is NOT a chip. Tricking the ECU into thinking that the air is cooler will NOT improve HP, since it will just increase the amount of fuel that is provided. If the ECU provides more fuel, you will LOOSE power, since the OEM air / fuel ratio is already too rich for optimum power.

 

Actually, its tricking the ECU to not retard timing for higher intake temps. I believe this makes you more likely to experience detonation.

Hokie resistor mod bad.
Detonation is even worse.

 

Yeah, all it does is trick the ECU into thinking the air is cold, so it doesn't automatically retard timing... Not always a bad thing, since there is a little tolerance for things like bad fuel and stuff like that. But in that case, you're stripping away the tolerance, so if you do get bad fuel, you're much more prone to detonation.

Also, it would only work in closed loop, when you're driving sedately. In open loop, you just fire on preset settings, basically ignoring all sensors. In open loop, the ECU would eventually learn that the A/F ratio wasn't right, from the feedback coming from the O2 sensor. So after a "honeymoon" period, your ECU would probably learn to ignore the resistor anyway.

If it genuinely did work, do you think Honda would have saved $0.01 at the cost of 20HP?

 

-And there ya go...Thanks, guys....

 

jackson racing does this with their ems system that accompanies the prelude supercharger kit. it sends a 0 degree intake air temp signal when you enter boost, which causes the injectors to stay open much longer on a honda. they do this to help get enough fuel under boost. for them, the timing advance of a few degrees is a side effect.

so even if those degrees of timing were actually safe to run all the time (probably are on 94 octane) the richening would most likely cause a power loss on our already rich motors.

and incidentally, this trick DOES work in open loop. the ecu has map adjustments or separate maps for situations in which the engine is warmed up but the air is extremely cold.

 

wow I learned alot today. thanks for the info even though I didnt start it.
