Im using project s stainless steel drop in air filter, but during my 1st gear rev, i feel that my pedal vibrate a lot comparing to using stock filter but good thing is the project s filter increase torque.

I then did a quick test by replacing back my stock one and the vibration gone and torque also reduced.

Can anyone explain how could the vibration appear?

Try resetting your ecu - probably with additional air the afr/ timing is messed up

I see, really got such thing? If reset helps, does it mean ECU's bug that cannot adapt well ? Can you explain more on how ECU respond on it ?

what engine on what car? maybe due to engine mounting because your engine produce more power...

just to let u know..the filteration is very poor tho....i've used it for 1K km, and found out my airbox and pipe leading to TB was covered by thick dust...

Saga BLM.

Timing is out. Probably as mentioned rakyat. Reset/adjust ecu should solve d issue

i see, so how do i tell the foreman, reset or adjust ? got value to to adjust 1 is it ? or he will know what to do ?

Stainless steel filters without mesh is only meant to be used on track where it is driving for short amount of distance before the engine is stripped down and overhauled. To use it daily in a road car will eventually damage your engine.

without mesh meaning ? i saw its like having mesh net

On other high flow filters, there is a cotton mesh/filter sandwiched between the steel mesh. Filters like K&N will require applying a little oil on the cotton mesh so that it can trap the smaller particles of dust.

Most stainless steel filters don't come with the cotton net in between, meaning your entire filter is made of stainless steel only. This is gives super highflow but suitable for track use only. Some company will make this into a drop in filter hoping that people will think that it can be used on the road. These companies don't do any R&D or testing before selling these products.

i'm driving non CPS neo..

eric, if u insist on using aftermarket filter then choose ori KNN drop in, otherwise better using stock filter....

agree with sleepwalker, SS filter is not suitable for daily driven cars..

perharp u should think on how to modify your air intake snorkel because BLM stock snorkel is very small..

I see, so do you think will it help to filter or perform near to cotton filter if i add oil on it ?

No it would not help as you don't have the cotton mesh to hold the oil. You'd just end up sucking the oil into the engine.

The next time you go to any car accessories shop, take a closer look at K&N filters and you'd know what I mean.

Yeah i saw it before, but K&N is very expensive, simota good or not bro ?

I only trust and use K&N and have been using it for the last 10 years.

wow ten years....
how often u wash ur filter bro?
d mesh net still intact ka?

The ECU is using your old ratio of 1X air hence pump 1Y petrol, with your new intake you are sucking 1.5X air but still pumping 1Y petrol hence your timing or Air/Fuel ratio is 'out'. Your ECU need to relearn the ratio, it does not mean your ECU is rosak

Don't need to go to w/s , just disconnect the clock fuse (if you know where it is) or disconnect you battery terminal (-ve) for 10 minutes and reconnect, go for a spirited drive (rev hard afew times) and the engine should run smoothly.

ECU got so smart will sense the amount of gas and air coming in and defect the timing? well i'll try this out thanks bro..

I didn't say I was using the same filter for 10 years. In the last 10 years I have used 3 different K&N filters in 2 different cars.

Added on June 2, 2010, 2:02 pmThe air fuel ratio would not change with a simple air filter replacement. The mappings are still the same and for most road cars, the ECU is not very adaptive and will not make much difference whether you reset it or not. Furthermore, a lot of the ECUs cannot be reset by just taking out the car battery. Settings are coded into the ROM and even with the lost of power will not reset the ECU. Only by plugging in an on-board diagnostic tool can you reset it.

Another point here, can anyone confirm that Saga BLM's ECU be reset with no current supply for 10 mins ?
