These are offered for ALL 97-04 Boxsters![/QUOTE]

Hi,

There are several ways to chip a car. You can add additional Maps, you can piggy-back on the OEM ECU and overide default Maps when certain parameters are experienced, or you can trick the ECU into seeing different conditions than those actually present. Some of these are actual hardware chipsets while others are merely a code over-write.

It is more difficult (therefore more expensive) to break the OEM code to write additional Maps (which are tested to work properly) than it is to create hardware/software which sends false sensor readings to the existing ECU.

I have not researched whether or not these chips differ in this manner. Also, each company's market research establishes the price point people are willing to pay and they price their products accordingly...

Happy Motoring!... Jim'99

Jet Performance, re-writes the code. That's why they require you to send in your ECU and then they overnight it back to you after they are done with the changes. That's the same thing that PowerChip does. So why is it better, if it is at all?

So I found their direct line instead of the 1800 number.


It's 310-235-1122. I left a message for Trav and the guy said he will call me back.

The guy was really kind.



I'm very excited. Not so much about putting my car out of commission, though.

my situation is a bit different but here is my plug for revo. After the 3.4 swap, I was still running the stock 986 2.7l maps. It ran ok, but there was a flat spot at 5k, which was associated with the changing over of the resonance flap in the intake manifold.

I contacted GIAC and they would not do any remapping for my situation. They actually were against remapping for this swap, so they said.

I then looked at revo and contacted them. I got a "custom" ecu remapping from the head programmer of Revo in England that installed the 3.4 maps into the stock 986 ecu. This was done by Hergesheimer Motorsports in Lake Forest. Bruce Hergesheimer was very helpful and personally handled the reflash, and over the course of 6 hours we got the revo guy to write the code, and then loaded it into the car. He wrote the code to account for the intake and headers/cats as well.

what a difference it made! No more flat spot at 5k, and a definite improvement in the throttle response, more "peppy" (theres a scientific term) engine feel as well.
It pulled harder in each gear. I am sure that it added a good 15 to 20hp, based on the change in feel. When I dyno it, I will have more definite numbers. But the change was not "wishful thinking" by any measure.

You will not go wrong with revo.

That's a very happy ending to your story, pecivil.


I'm glad revo can be a credible company and I'm disappointed that giac was a let-down.
