does the powerwire really do much, what does it do??
Hopefully these answer your question homie.
1. Will this harm my PCM in any way.
No. The POWER WIRE only simulates intake air temps that are 20 degrees cooler at all times. Your PCM will not know any better and it will still adjust as advertised. The only difference is that the POWER WIRE causes your PCM to advance the timing by 3-4 degrees at WOT. This is where the 8-10RWHP comes from.
2. Will the POWER WIRE cause my engine to run rich?
No. Your PCM is programed to keep your Air Fuel Ratio nailed down to 14.75:1 at all throttle positions below Wide Open Throttle (WOT). So the POWER WIRE can not effect your Air Fuel Ratio anywhere below WOT.
The POWER WIRE will increase your AFR by approximately 2.5 percent at WOT only. In most cases thats enough to help improve on the factory slight lean setting.
3. What does the POWER WIRE do? How does it make HP?
The POWER WIRE alters the Air Temp Signal to your PCM to read 20 degrees cooler at all times. So if the actual intake air temps are 90 degrees then the POWER WIRE alters the signal to read 70 degrees. This causes the PCM to advance the timing which is worth approximately 8-10RWHP.
4. Will the POWER WIRE hurt my fuel economy?
NO, in most cases the POWER WIRE will increase your fuel economy by 1-2MPG when driven under a light foot. As long as you do NOT hit Wide Open Throttle the POWER WIRE can NOT add more fuel. The MPG gains come from the degrees timing advance effects the POWER WIRE induces.
On the flip side, at WOT the POWER WIRE does cause your PCM to add approximately 2.5 percent more fuel. So If your at Wide Open Throttle allot then YES your fuel economy will take a dive by approximately 2.5 percent. But the additional 8-10RWHP HP at WOT makes up for the slight loss in fuel economy.
Bottom line, if you want increased fuel economy while useing the POWER WIRE DO NOT put your foot to the floor... but what fun is that.
