Miller MAF

Post by Val_C » Fri May 24, 2019 2:54 pm

Since installing Gen I Miller MAF system to my car I've had two issues with it:
1. Car was constantly running rich, it was obvious by the color of spark plugs, exhaust and... smell. This is not solved and Miller was no help.
2. Under hard acceleration between 4 and 5K RMP there was very noticeable stalling. It wasn't critical but annoying. Miller also couldn't advice the reason.

Recently I found that someone reported about the second issue on some FB group and that it was resolved by installing mesh affront of MAF sensor. Miller system never had anything before the sensor, while all production cars do have one or even two meshes there.

The MAF mesh was sourced during one of the trips to junkyards.

I trimmed the metal mesh to fit between the Miller intake and original BMW flange. Unfortunately, the piece wasn't big enough to cover all corners, but I've decided that it's OK for the test.

Installed.

I put the system back to the car and took it out to test drive on highway. Amazingly, the stalling on high RPMs is gone now. I am quite happy with such an easy solution.

Cibie 35-series driving lights.

Post by Val_C » Fri May 24, 2019 3:13 pm

Euro BMW driving/fog lights cannot be installed easily under my bumper, as it was mangled badly by previous owner who cut it to have inter-cooler installed.
So I was debating what to do with the airdam openings: leave them as they are, install front brake cooling ducts, which could be cool but not necessary or find suitable driving or fog lights.
Opportunity came via FB marketplace ad where someone was selling 3 used CIBIE 35 series driving lights.

Image

I couldn't resist the price and bought them after checking airdam opening dimensions.

Quick test fit:

The inner part of the bumper might require some trimming:

Fun time under the car modelling brackets:

Bracket model is almost completed. Another test fit and then fabrication.
3-D printer would be cool, but will require some $$, so I will just use aluminum plates cut on size and bolted together with angles.

Hi Val how are you.

The MAF looks like a great fix. so if I understand, the reduced volume of air thru the MAF is telling the ECU

to reduce fuel flow thereby leaning it out just enough for better drive-ability.

Great fix.

Take care Val.

Exhaust fit and function?

Post by songzunhuang » Mon May 27, 2019 9:15 pm

Val,
I'm looking to replace my exhaust system soon and noticed that you bought the Walker system. How's that working out?
Also, I love your "oil change". That was one for the ages.

Thanks in advance for any details about the exhaust.

Hello,
I hate to admit, but the Walker is still in the corner of my garage and not in the car. I am planning to have it installed this Thursday, I will report when done.

Hey Bob! All is good, no big changes, just life.
I'll have to run through a couple of tanks of gas to see if system will lean out, meanwhile the stalling is definitely gone.
I am not sure about physics behind the fix, but the opening is reduced like for 50%.

Still with IE.

IE is out.

Walker installed. It's much quieter than IE, but I feel that chrome tips protruding too much. Will trim them later. Cannot tell anything about installation as I wasn't at the shop at the time.

Hi Val,
Just gave me a thought--I have an IE exhaust with no droning at all.

But, when I install the higher HP motor with headers and custom down pipes

will it then cause droning, oh I hope not--can't stand to have any more setbacks.

Yeah, you're right-- seems like all the Bronzit-Beige are all money suckers

and the proof is that at 75 I'm still working to feed the beast.

Bob, I think yours IE shouldn't drone as you've got it new. Mine was used from roll-over car, I believe that something might be damaged in it when I've got it.
Nevertheless, the Walker is not so cool, but much quieter.

Thanks! Shortened the tips a bit, so it looks just right now.
