Re map?

[liam996]

Worth doing? If so where is best place to get it done?

Vehicle still obviously fast but seems to have lost a little 'pace' [] Is re mapping the best thing to do to increase power?

Thanks

Remapping a standard NA car is a waste of money IMO. How are your cats? When they start to break up they can block the exhaust.

Cats are brand new, well 600 miles new.

How long do they typically last?

Have you performed a forced adaptation?

With a cold engine, turn the ignition on but do not start the car or touch the throttle & leave on for 1 minute. Turn off & turn ignition on for at least 10 seconds & then start. Go for a decent length drive over a mix of roads.

Very dependant on how the car is driven. Short journeys on cold cats are a good way of killing them. My old C4 was still on its original ones when I sold it at 65K miles. My GT3 had melted its original ones by 45K miles but the replacements are still good and the car is on 90K miles now. It's probably done about 70 trackdays on the second set of cats.

Just to add a brief +1 to Nick's comments about re-setting the adaption on the engine ECU.
Mine (2004 996 C2 40th Anniversary) was re-set for the first time in my ownership during the 48,000 mile service & I wondered initially where the very significant additional performance had come from - the difference was really marked !
It was only after a lot of forum searching I realised what had happened & now make a regular habit of re-setting it.

For anyone who doesn't know how it is done, here are the instructions. These only apply to cars with electronic throttle. (DME7.2 and 7.8).

For early cars with mechanical throttle (DME5.2.2) you have to disconnect the battery for a few seonds. If you do this on an early car, make sure you have the radio code, and switch the ignition to position 1 before disconnecting, or the alarm siren will go off.

I'm gonna give this a go as I seem to have lost abit of oomph. Richard what DME do I have ? I know I should know this but you know what I'm like. Thx Roy

 

[Richard_Hamilton]

LOL! I DO know Roy. [] Not that there is any reason you should know what DME you have.

You have 7.8. Just follow the instructions. Just need to wait for a day when it is 10C............

Thanks, that's great i will give it a go. Thanks again.

I did this a couple of days ago and WOW what a difference.

The throttle is more responsive and feels like a new car.

Thanks for the instructions
