S4R Arrow full system

11-01-2005, 09:35 PM

I'm just about to fit an Arrow full system and have conflicting reports as to whether I also need a new ECU module at this time. I've had one mechanic say that it won't be needed until I put a high flow air filter in and another who insists that a new ecu will be required at the time the zorst is fitted.
Has anyone been down this upgrade path and have some sage words to offer?

Any comments greatly appreciated.

I have a Full system on my S4R with an open air box/filter.
No ECU upgrade, Fine with no problems.
Only thing I did was turn the Idle up a bit, it got a bit lumpy on tickover.

No running problems at all.

Just make sure you take the baffles out, so you can hear the 996 ROAR!!!! :twisted:

You are gonna love it.

Vman thanks for letting me know. I'll end up getting a remap at some point but for now I'm looking forward to hearing the exhaust over the clutch
