Kearney Posted August 10, 2009 Share Posted August 10, 2009 Just fitted my new de-cat I got off a member off the site. Seems a tiny little bit too big of a bore its about half an inch bigger. Anyway I put it on and the car doesn't seem to make up its mind if its quicker or not. One min theres a flat spot at lets say 3000rpm... next there isn't! Same situation happened when I fitted a new ram pipe for my induction kit but after a day's driving I just turned it on and for some reason it was really nippy! Duno whats up with it, the car HAS to be possesed I'm guessing its the ECU learning and trying to adapt to the new part maybe? It does without doubt seem better up high RPM heres the pics Link to comment Share on other sites More sharing options...

patrikbrunt Posted August 10, 2009 Share Posted August 10, 2009 Glad it has arrived safe Have you tried resetting the ECU ? Link to comment Share on other sites More sharing options...
Kearney Posted August 10, 2009 Author Share Posted August 10, 2009 Glad it has arrived safe Have you tried resetting the ECU ? Yeah me too, was hoping it'd arrive before suprapod but sure its no problem. I'm thinking about doing that. Just going to pop out and disconnet the negative on the battery and have some dinner.

pedrosixfour Posted August 10, 2009 Share Posted August 10, 2009 (edited) Some say you'll lose some mid-range with a mod like that. I personally just cut my cat open, removed the innards and welded it all back together and I don't see any loss in power, anywhere. It does sound like a banshee with her nipples caught in a bench vice tho What fuel are you running it on? If the ECU reset doesn't help and you are running it on the normal Irish petrol, 95 octane, maybe you should try it on Maxol E5.

I'm running it on E5 anyway, hopefully the ECU reset will do the trick. Any pics of your engine bay/exhaust system?

w41k3r Posted August 10, 2009 Share Posted August 10, 2009 i have double decat on mine i reset the ecu straight away after fitting them there was far better throttle response instantly noticable by me and my bro so there must be a small increase but also if you double decat the n\a it is very loud my neighbours will vouch for that lol http://www.youtube.com/watch?v=yJ-9gTeIMK8 Link to comment Share on other sites More sharing options...

It seems like the 6 branch is next on the list. Can't seem to get a set of cams anywere, only If my car is distributor-less is the only way a set of BC cams will fit her.

Well I'm happy with it now, there isn't a lot more I will do to the lump at this stage. A TRD panel filter is in the pipeline. Cams may leave the car a cnut in every situation apart from a track. A lumpy gutless pig to drive around town and a very narrow powerband will mean endless gear changes when you finally get to open the taps. Link to comment Share on other sites More sharing options...

Dazzi Posted August 11, 2009 Share Posted August 11, 2009 Same thing happenms to me. There seems to be a flat spot between 3500-4000 and sticks there for a couple of seconds. Do you have an aftermarket airfilter? Im sure mine might be caused by this. Link to comment Share on other sites More sharing options...

But otherwise is all other RPM its going a bit quicker Link to comment Share on other sites More sharing options...
Dazzi Posted August 11, 2009 Share Posted August 11, 2009 When I had the EMU installed on the car when it was NA-T I actually managed to get rid of it. Think it showed up as a rich spot on the map trace. Took the NA-T kit off and the EMU and it came back lol Link to comment Share on other sites More sharing options...
w41k3r Posted August 11, 2009 Share Posted August 11, 2009 i dont have a flat spot and the air filter i use is an apexi routed to front left cutout in bumper so no heat soak you sure your not talking about the other valve in the intake Link to comment Share on other sites More sharing options...
Dazzi Posted August 11, 2009 Share Posted August 11, 2009 It could be the short to long runner valve... Im going to have to experiment with it, say jam it open then go for a drive and see if the flat spot is still there. Link to comment Share on other sites More sharing options...
w41k3r Posted August 11, 2009 Share Posted August 11, 2009 on supraforums i think they either remove or jam it but isnt it there for low down torque i carnt remem ill have a search for it and report back lol Link to comment Share on other sites More sharing options...
