Found the problem when trying to get my wheels sorted out.

When under hard acceleration/load the car would feel like it was vibrating and Sluggish (found out to be a slight missfire) Put my old filter back on and the car is ok.

Car was chipped/re-mapped at Jabbasport with my old filter on. The only thing i have not tried yet is the k&n filter without the lan pipe or my filter on the lan pipe.

Had no problems with the car around town but never push it.

Should i call Jabba? as i dont want to pay another

I think i'm correct in saying that 1 or 2 others have fitted LAN Kits (or Dynatwists etc) AFTER being Jabba'd, and i don't recall any similar problems..

If you're convinced that's where the problem is, give Jabba a call, they're a decent bunch and will advise you on the best course of action. Even if the map needs a "tweak" i doubt they'd charge anything like full price

I have a feeling that Jabba charge something like 75 squids for a tweak of a remap. Just seem to remember hearing that from someone.

Apparently should make no difference if you add an CAI/filter or cat back/full exhaust system as, the ECU will adapt to them.

Only things which will need the car to go back on the rollers would be an N75 valve or if there's increased flow i.e ported head.

I can't see how a CAI would cause vibration...a strange and interesting problem....but do give Jabba a ring to discuss......it won't be a problem. If ever anyone has a remap related problem Jabba have no problems with trying to sort it out.

Are you still running the standard wheels and was this problem evident when running them?

Or if you are now running non-standard wheels has this problem started since the new wheels?

When i first put the bigger wheels on the car had the filter it was re-mapped with and every thing was fine.

I put the filter on but only run around town so never noticed it until now.

You only notice the problem over 50 mph when pushing on. The car was vibrating/juddering and accelerated slowly. Since i have put the old filter on the car now pulls much stronger and smoother from 50-100.

I thought it would make no difference adding the CAI after the re-map so thats why i put it on. I thought it was the wheels but my brother tok it out and said the wheels are out of balance but the engine felt like it had a slight missfire so we changed the filter and cured the problem

Maybe as the car had only 2500 miles when it was done and now has 4500 may have something to do with it.

Going to try the K&N filter on without the lan pipe tomorrow.

Adaption should occur after about 100 miles so you've done this.....another way to force adaption is to remove the battery terminals and wait for around 5 minutes then put them back on.

I had my remap then add a Dynatwist CAI......had no problems with it....since add a Milltek dp and sports cat and had no probs with that either.

A strange issue......keep us update with what you find out.

You said it felt like a slight misfire.......do you know what coilpack version you have? You know where I'm going to go with this.......

...also what revs does this occur or is it just mph related?

Just trying to get a clearer picture.

Cheers.

Adrian.

Don't know what coil pack version but the car is only 4 month old so should be the latest hopefuly.

It is not rev related more speed. Did the same in 3rd, 4th & 5th at 80mph.

So adding CAI and full exaust would not increase flow?

Do you understand that no increase=no extra performance?

Of course the ECU chipped or not will adapt to some degree.

Just passing on what was told to me.

The ECU adapt boost pressure and so on, if the engine breaths better.

I did block 115/120 runs before and after my 3" with highflow cat and 2.5" catback.

No diffrence in either hp/Nm nor boost. You need the remap to gain performance.

BUT you get a lower turbocharger temp if you stress the engine, when having a full exhaust.

So if I add a CAI, a sport dp/cat and cat back exhaust the ECU will adapt to it but.....will not give any performance gain??

When we say the ECU adapts...what does it acutally do?

Not disagreeing just interested in finding out more.

Seeing as I've had a CAI, sport dp/cat fitted since my remap I really should have had the car mapped to take these into consideration? If I we to put a N75J on I know you get better response and a little more boost but, would I see better results if the car were remapped with this as well?

Cheers.

Adrian.

The values from 115/120 are no longer valid when you

change components on the engine. The are computed

by the ECU from the sensor values with constants that are

no longer correct.

The ECU will try to keep the boost it has been programmed with but the air temp will be lower and the air flow higher so

power will be higher.

The adaptation is changing the ignition timing to increase

power and fuel efficiency.

/Eric

The block 115/120 STILL work if you change componentens on the car.

It is not some constant the ECU works with.

If it were the case then the Load block (Nm) would always be the same. And it aint.. remap the car and everything changes.

So if I add a CAI' date=' a sport dp/cat and cat back exhaust the ECU will adapt to it but.....will not give any performance gain??

Adrian,

I can certainly confirm that getting the exhaust and inlet done before getting the remap pays off. Dont know about N75 though-if you give Mike a call I'm sure he will confirm and advise you on N75. I recall he didn't recommend it but if you go back he can test it out.

Called Jabba today and the problem is the tube that connects the lan kit to the maf housing. Something to do with the maf end being smaller than the lan side causing turbulence.

Was going to have a play with it but removed the filter and it has holes in 3 of the pleats. Must of been rubbing when the mount sheared off

Have to order a new filter now. May get a different shape one this time so it does not happen again.

How many people have had mounts break off on their cars?

Would it be a good idea to reinforce the mounting point on the car before fitting a LAN kit?

Does anyone recommend the carbonio kit?

Cheers

Phil.
