One thing I'm worried about is the airfilter:

Its leaking oil out into the air tract, and also out of the airbox, and onto the exhaust system.

The oil has probably done-in my MAF, and has caused smoke which appears to be coming from under the turbo heat shield...that scared the isht outta me until ckevin pointed out the cause....

I wonder if the oil gunking up the MAF could be causing the motor to ping in some way?

Oil in the intake charge lowers the fuel's octane rating and in turn lowers it anti-knock abilities, the result is detonation under high cylinder pressures and you get audible pinging, which means trouble. Detonation in your motor is like beating on the pistons and rod bearings with a large hammer. Not good.

 

I am not familiar with the ITG panel filter but it seems like the filter requires oil like the K&N. If that is the case, then it is possible that fluid is being sucked into the direction of the intake. I had this problem when I reused the filters in the box. I think that is why the genuine STi air filter is a cotton type of filter and has no fluid. It is somewhat unique in a way and have to admit expensive.

I think what most of you are talking about when you hear that noise is not ping but the sound of the lifters. This is what I was told when I asked about what the clicking noise from the WRX coming from the engine bay from the outside of the car.

I run in particular 91 octane gas from 76. Call me **** about picking out gas companies but I would rather have gasoline that does not have MTBE.

 

I think its either pinging or something is lose inside the engine compartment, or chassis/suspension....

I don't know what brand of gas to use these days....I normally buy Chevron, but now may switch to 76.

I don't like MTBE, but then I don't like Gasohol (Gas/Ethanol) either....personally its BS that we have California-spec garbage fuel, and no 93 or at least 92 octane fuel.

I will switch to the STi filter next week, and will have the MAF checked out.

 

I have had some experience with the STi filter. I will tell you this. It does filter out every little thing. The amount that the filter cleans out is amazing. But I will say you do get what you pay for. But, yes there is always a but, the filter needs to be replaced every 5k-10k miles. It gets filled up pretty quick. I had one in my RS conversion for 8K and the filter was filled up with all kinds of little things in the cracks. I could not imagine as to how much it clean up. I know that replacing it every so often gets expensive, but nobody ever said speed was cheap.

 

If you're **** then so am I. I refuse to put any other gas in my car, 76 is the only thing I have put in my car from when I bought to this date.

I think Dahveed or David asked what a VME is and I still dont know either but on AcronymFinder.com it is a "Virtual Machine Environment (an operating system of ICL mainframes)". I hope thats right and answers the question.

 

1600 miles, 91 octane Chevron, proper break in (did it in 2 days ). No pinging at all. In fact, under boost at above 4K, the ECU pulls timing down to about 12 degrees and I can see the ECU *adding* timing as the RPMs climb. During WOT, the ECU is just dumping gas and the car runs super rich (11.025:1 AFR).

I am getting this data off the OBD port via my SCES (http://www.psi3.co.uk), monitoring boost, ignition timing, knock correction, and lambda.

 

hatchy,

got pixs?

where'd ya get it? how much? you install it?

 

I don't have any pics, but mine looks exactly like this one

here

I got it from Mark @ Quantum Racing for about $500 and the install was pretty easy, took me about 20 mins.

 

was the install plug & play? or plug & PRAY?

 

Looks cool and would seem to be a valuable asset to tuners to see what the stock ECU is doing.

 

Just plug and play, and the plug is keyed so you can't even insert it the wrong way

It is a little on the pricy side, but still a good value for what it shows you. Wish it had logging tho...

 

It is a nice concept, but you can't really tune your car off of the stock wideband. It just sucks to tune with. I hear that it reads really lean. If I am going to shell out the dough, for 5 times that, you could go with the Motec logger! Hell yeah! And a delta dash to boot! Whatever is clever though! I wonder if anybody will be able to read this! I sure am a jackass! Sorry guys but I had to do it!
