Maf Problems

[volcano rs]

due to boost pipes coming off 3 times recently during a remap i have had made a new maf casing in nylon with beading at both ends and space for brackets to fit which will stop the pipes pulling off .here are few pics

[Acidburn]

Quite a nice setup you've made there, I like the brackets you've used to stop it pulling off as you've mentioned, is it worth putting a jubilee clip on the pipes after this (it looks like this is a shot whilst your doing it due to one of the pipes not being connected)

How long did it take and what did it cost material wise?

That looks expensive, but great!

I'm dissapointed, not stainless?

Nice work though.

its a very tight fit .jubilee clips will go on once i've soldered the wires and put it back together cost is not cheap £150 thats if he makes another one (and thats just the casing ) this was made out of solid piece of nylon .

Nice work though.

funny you say that i did go there with some stainless but the engineer said to use nylon to keep the cost down .mine didn't cost that .but he said if he was to make more thats what he would charge due to the time involved .

This would polish up.

i take it you have the maf on the pressure side nice work there. is that a s1 manifold you have there any more pics

home made something between imsa and s1 .look under sport quattro pics you'll see more of the manifold .and yes on the pressure side .
@ robo that looks good in alloy .

Is it possible too put the MAF on the pressure side without a remap ??
I want to hear the bov

no you cannot,because on the pressure side the air is travelling with less speed,due to higher pressure and the signals from the MAF are different.So you need definitelly a new map

What amazes me is how easely people seem to have taken apart the original maf to remove the sensor,so they can place it in a bigger tube.I had an old maf and tried to do that,ended up at a stage that i couldnt remove it without recking it completelly.

its not as difficult as it seems ,you just have to be a bit patient and break the seal (same stuff thats used on the rear lights ) just cut the solder on the wires and pull it out .

oh and then you need to resolder everything?and that doesnt damage the sensor's electronics?

It doesn't damage the sensor's electronics. However sensor contact group is spot welded, not soldered, and material is not good soldering one. Which makes good soldering - quite a PITA (with proper surface preparation, soldering paste, etc.).

If you solder it "best as I could" newbie style, it is almost 100% warranty, that after some time it will break or will give impact to sensor readings. BTDT.

And BTW I want to remind you, that motronic uses MAF signal in kind of weird way, and changing tube diameter is non linear change of output signal.

In short - it gives person who maps lots of trouble. I don't know tuner, who can compensate this change by just remapping.

if tuners have done this before and have some experience with larger tubing,it wont be a big problem to remap.right?
