Decat, results?

miniturbo · 4th May 2008, 19:43

Hi, im hearing things on other forums that there have been mixed results from fitting a decat. Some with gains some with power loss at peak/high revs.

Anyone else fitted the mod?

We would never recomend fitting a decat unless you can adjust the fuelling to allow for the higher gas flow making the engines run leaner.

On the older EP3's we saw cars loosing power with the decat fitted on a standard ecu. If we fitted a mappable ecu and adjusted the fuelling/ignition we found good gains midrange and upto 10bhp at top end.

There is no reason why the FN2 won't be the same, so would strongly recommend holding fire until the mappable ecu's are available.

Decats used to work on the old Pugs, Saxo's, Novas etc as you could adjust mixture manually on some cars. You can't on these Honda's.

It gets smaller as you said tp. Its going back im affraid. Plus theres an area of weld that is paper thin, bit of engine movement and heat expansion and i think it would start blowing in now time.

Hey ho.

OK. Its the same as mine. The nuts that are welded on to hold the lambda sensors were also distorted on mine through too much heat when welding.
