I'm wanting to add a performance chip by revolution to my 88 vert but I am wondering if will make a big difference in HP and if it will do any damage to my engine. Has any one added a chip to their RX-7 if so what brand and did it make a difference.

 

Never heard of them. Any info on what the chip does? Also what do you have done to the car?

 

The SURGE Performance module simply wires into the factory harness of the IAT sensor. The module will work with the sensor to provide a new signal to your vehicles computer, or ECU. The ECU then adjusts your air/fuel and timing advance curves to new performance settings. I have a cold air intake ,borla exhaust racing clutch thats about it.

 

useless mod imo

 

I don't think the IAT plays a big role in figuring out the timing and fuel maps so I doubt it will make a big difference. Plus doesn't it give colder IAT values to the ECU so it can richen the fuel mixture? This would lower HP output on your NA car. Its also a very universal mod, not model-specific.

Search titles only for "chip" and see what type of search results you get.

 

Not worth it. The only 'chip' [i.e.: anything that utilizes stock ECU] worth anything is the RTek, since it actually does something and you can tune it.

 

This is from the FAQ. Its just an inch or two below the button you pressed to ask this question.

"Do those cheap eBay "speed chips" or "mod chips" work?
No, they do not. In fact they're not even a "chip" (integrated circuit) but simply a 2 cent resistor in a fancy case. The theory is that by putting this resistor in series with the IAT (Intake Air Temperature) sensor you can fool the car into adding more fuel by making the intake seem colder then it really is. In reality we all know that more fuel is not equal to more power and by messing with the IAT sensor the car will run too rich and lose power. Also the price is a total ripoff considering that anyone could go out and buy the same resistor for less then 5 cents."

 

I'm with the other folks on this one. A chip wired in to the IAT sensor will not do much for you performance wise. Not to mention it's not really a "chip." It's a resistor that lowers the voltage signal to the ecu. Which tells the ecu it needs more fuel and timing. Now that wouldn't be too bad on any piston engine. On your stock NA motor it's only going to make a pig rich mixture even richer. All in all you will see a loss in horse power and a big drop in already horrible gas mileage.

 

And just to add to this, N/A's generally run richer and so tricking the ECU to run even richer is not a good idea =P
