RoW reprogram?

Recommended Posts

I have a 2004 986S that I use as a dedicated track car. Thus far, I have only upgraded suspension bits.

I am considering stripping the car and installing a full cage at the end of this season. I am hesistant to make engine changes....but....I am interested in eliminating the catalytic converters.

I have been told the following and am looking for thoughts on these items:

* the catalytic converters integrated into the headers rob the 986 of power (Note on an 04, there is a primary set integrated into the headers, and a secondary set after - the primaries have the sensors, not the secondaries)

* you can reprogram the ECU using a PST2 to RoW, and eliminate the CATs, as the RoW configuration does not look for cats

* the s-car-go headers give good flow and good HP gains

I don't know if any of this is correct, and am looking to see what you guys know.

Also, it would appear that this would be a simple change - new headers and a ECU change - and it would not trigger wierdness elsewhere that would require endless tweaks. Naive thinking??

Euro 986 have only pre cat. sensors, sensor and cat. are integrated in the exhaust tube between headers and rear exhaust. Option: install Euro headers - install Euro exhaust tube and eleminate the cat. by welding a tube in between - install your car pre cat. sensor in the original empty spot of the Euro exhaust tube - eleminate your car post cat. sensors - reprogram DME to EURO NORM 3. No fault codes will appear but you never can pass trough a environment gas test.
