... but boxster is correct.
The '97 - '99 ECU cannot be programmed like the newer gen2 986s.
Originally anyone who reprogrammed one of these had to physically open the ECU and solder a chip onto the existing board.
Recently my company developed a way around this by manufacturing a special computer that simulates the car's parameters and offers some signals that were missing in order to reprogram.
We can now remap the ECU by simply pugging it into our computer. We download the original map and upload the modified one, according to the customer's requests.
We still have to physically have the ECU in our hands.
We've also found ways around some of Porsche's "failsafe" modes:
1- We can completely eliminate the CLU (Central Locking Unit) and all its wiring from a car and...
2- We can completely eliminate the immobilizer (transponder for the key).
Porsche said that this was impossible. we now do it routinely for race cars that want to eliminate weight and simplify the electronics by just installing a start button.
If anyone needs more info you can contact me directly.
Happy Boxstering,
Pedro
