Hi gents,

 

as some of you know, I bought MBES2's old car from a chap that bought it from MBES2 and had it for a few months.

 

In the initial fore sale post, the car was listed with Apexi filter, however when I now checked it has a blue cone filter on which I could not find any naming at all so probably cheap.

Furthermore the filter looks completely dry? In my experience they are normally somewhat oily?

 

As I have trouble with a P0130 fault code, which apparently sometimes is linked to the MAF playing up, and I was considering getting a new MAF to check if it is indeed the MAF, maybe if the car has been run with an inadequate filter, no wonder the MAF would be toast.

Either way, if I fit a new MAF, I want to make sure it lasts.

 

As I have an 80 mm MAF, if I wanted to go back to an OEM air box how would you make the connection as I assume the air box has a different diameter?

Or is there some sort of cone filter which does not kill of the MAF sensors?

 

Is the air box specific for the  VX220 Turbo or can it be taken from another model?

 

Best source for air box? I guess Liz on here?

 

Thanks guys!

Buy an airbox from Lix as you mentioned.

 

Then buy some silicon reducing pipe off eba to fit it.

Or get an AEM dry flow filter (no oil that can kill the MAF), used that for years with MAF without any issues. Very good filter, probably that's why K&N bought AEM induction

Or get a Honda S2000 oem cone filter. Good for 400bhp and the best paper filtration. £15. An 83mm ID silicone hose just fits over the neck. http://www.carparts4...CFYGd7QodsKcMJQ

Can't help you on the technical details re. 80mm AMM, but if you do choose to go back to a standard air box, I have a brand new one for sale complete with new paper filter. Selling for £45 including postage.

PS. VXR200 was delivered with a foam filter fitted inside a standard air box. It was pre-oiled and quite a few owners went through several AMM. Vauxhall fix was to replace with a standard paper filter.

P0130 relates to the primary lambda sensor

 

Do you have access to read the "long term fuel trim" and "short term fuel trim" values stored in the ecu. 

 

I would not be changing out filters or AMM at this stage, without knowing the fueling was wrong.

Is it possible to read fuel trim through opcom? Is there a logging function that could record several parameters to see if something strange happens when the code comes? I have opcom as well as bluetooth elm adapter so can run android apps as well if there is a better way.

+1 for the AEM cone, Nevlock sell these for about £40 each on ebay. Used this filter on many different cars and never had an issue. Unsure on fueltrim but there are many different parameters you can measure on opcom. If you disable the ones you don't need it'll update faster too and you will get better live data.
