I was wondering if someone could tell me if this chip would work well with a 1992 camaro 3.1? Theres a bunch of them availabe im not sure which one to get. Burning my own is not an option. The car is slightly modified ( exhaust, cold air intake). Do chips allow for more improvements ( headers ect)?..thanks

there not worth it..... get headers, there will be more difference.

 

All the cips do is richen up the WOT mixture a little, advance the timing curve, and on some models they turn the fan on earlier. If you're planning on doing other upgrades, then you'll soon run out of room even on the hypertech/jet chips and have to learn to make your own.

 

Ok so it seems headers are the way to go. I saw on a post a while ago that in order to install the pacesetter headers, you will have to remove the smog pump. Dont you need this for Pa inspection?

 

If they do any kind of visual inspection...yes.

 

What about the gas cap and emissions test, if you dont have a smog pump wont it show up on the test?

 

The smog pump only comes into play when the engine is cold. Once it warms up there shouldnt be any difference.

 

what does the smog pump do actually? tryes to make the exhasut cleaner? Does it reduce power like ive been told and will the 2.8 headers fit with the smog pump removed?

 

The Smog Pump injects oxygen(in the outside air) into the manifolds when the engine is cold so that any unburned gas and Carbon monoxide can be oxidized before the cat warms up to operating temps. Once the convertor warms up, it does a much better job of oxidation than the air pump, so it just dumps air back to the atmosphere.

It only takes about 1/4 hp to run the pump. You'll never feel a difference by removing it. The only time you really see a difference is when you have a built motor and are trying to squeeze that extra 0.001 second off your car.

To my knowledge, the Pacesetter headers do not have the AIR Injection Bungs installed and are therefore not legal for any 2.8L with AIR Injection, but should phyically fit without pump removal. The AIR Manifold won't be able to be hooked up though.

 

what do you mean by "Air Manifold ". I thought the 3.1 was a mfi.

 

It is. The AIR manifold is the tubing that screws into the exhaust manifolds from the AIR Pump.

 

If this is true, then where do they get the hp figure from that is advertised with the chip? I beleive the hypertech chip for the 3.1 shows an increase of +14 HP....

 

Because they don't tell you that that specific HP increase came from a 1999 Chevy Silvirado with a 5.7L motor. They just say that their product has give this increase, but they don't tell you what it is on your specific engine.

 

So these over the counter chips don't add any horsepower at ALL??? And how would you go about burning your own chip??? Im sure not everyone (such as myslef) is an expert in that area???

 

Just lurk on the DIY- PROM part of this site... Will tell you everything you need to know! there are a lot of good guides stickied at the top of that page.

 

I didn't say it won't give you ANY power gains, just that it's not what they advertise. They advertise "up to 14HP gains..." which means that depending on the application, you might see these gains, but they are not typical.

In my opinion, I don't think they give you enough gains to make the cost worth it.

 

I've also seen advertised that these chips can provide firmer shifts points with vehicles equipped with automatic transmissions. Is this also misleading?

 

On our vehicles...yes. The 700R4 Trans that 3rd gens are equiped with are not computer controlled transmissions, so the only thing the chip would change is the qualifications for TCC Lockup. They usually move this to a higher RPM to give you the feeling of more power in 3rd gear.
