Which tool for DIY Remap on 1.6FSI?

spike: Yeah will be very careful with that. which is why I'm opting for the bmc carbon kit...supposed to keep the air cooler. will also feed the air in from somewhere out front...a bit like what scott has done on here already. Looks like a good plan. I don't have the add on fog lights on mine anyway, so those spaces on the bumper look prime for this purpose!

I put a shielded induction kit on my TDi for a bit, with a feed from the fog light but removed it, after Skipton opened my eyes to the potential problems, including moisture ingress, hoovering up water / and road debris etc.

Ouch, good points there. Never thought of that.

Hmmm...must be somewhere good that we could root the air in from, that doesn't hoover stuff up though...any ideas peeps?

How was the performance while you had it on there though? Was it worthwhile to begin with? Could you tell any difference?

sport models come with 17" 9 spoke rs4 style wheels. Not 19". You would be running on 35 profile tyres even with 18, can't imagine what rubber band tyres would be needed on 19"!

I have used the standard intake from the standard air box, it is behind the grill in the bonnet, I cant remember if I cut it or not but I shoved a aluminum tube over it and pointed it straight to the air filter the read intake in my pictures wasn't supplying enough cool air, now I have 2 air feeds I have no problems, the new air feed goes straight to the air filter and the first attempt (red one) is now just pointing near it so no water goes near it as it is quiet low down. Ive had no problems and I have driven in some storms!!!

sweeeeet...got any pics of how you did it? which filter you using? Reckon a bmc carbon one is worth the outlay?

A bmc one will probably be better performance wise as it keeps the air allot cooler, the only reason I never got one is because I wasn't sure of how you would clean it as its a sealed unit, and they are a bit expensive to buy a new one every year or 2. I have a piper cross universal one, it looks and sounds good and noticed a small difference with it. my camera phone has broke so I cant get any pics up of it now its finished but I have a picture on my profile of it when I first fit it. sorry I would put the picture here but I don't no how, hope you don't mind looking

Thanks

just seen the pic on your profile. looks great. might go with the pipercross...bmc is expensive, for probably very limited benefit.
 
I have a FSI and I'm thinking about a remap too.
But what worries me with the FSI is its 2 (or 3) running modes.
At low revs/light load, it's lean burn/stratified petrol injection.
At higher revs/load, it's "normal" engine.
And in-between, it's an intermediate mode.
The transition between these modes is operated by a flap in the intake manifold to make the air flow "twirl".
I also suspect that the maps are different between these modes.

I had already inquired at a renown remap place (he does Ferraris, etc.), but he didn't mention this. So what, doesn't he only remap the high rev mode ?
I'm not only after some extra bhp at the top of the power curve, but also (and mainly) some gains in torque and "smoothness" under acceleration.

With an aftermarket air intake kit like the BMC CDA, do you just block the EGR valve to bypass it ?
 
This is me guessing only so please take this with caution.

I suspect the remap will not impact the FSI mode as that will be something which sits "on top" of the regular map and is activated by the load of the engine and other variables. So whatever map you have, the FSi part of the engine running is only activated at low load conditions and the mix is leaned to whatever the FSi conditions allow.

The aftermarket filter would not normally require the EGR valve to be blocked or bypassed. I have seen some people have fitted them and left the EGR valve operating as per normal. I would imagine that you could block the EGR without fitting an air filter.

There are other things you can do to keep the FSI a little more efficient such as...

Normal things...
Regular Service and fluid / filter changes
Cleaing Throttle body
Cleaning of the injectors (via additive or v-power fuel type method)

Additional cost items...
Crankcase breather to vent to a baffled catch can.
EGR Valve blocking and mapped out in the ECU
Cleaning of the inlet manifolds

I know this sounds like a broken record, however it seems the best you can do with the FSi engine is to try and keep the internals of the engine, especially the intake path, as clean as possible as that really impacts the performance of the engine.
 
Hi Pummy,

I've looked for the EGR valve for ages looking to cut this off...can't find any pics on the web of where to find it on our car though. any clues?...or pics? would be hugely grateful dude.

Also on the subject of breathers, do you just whack one onto that valve that pokes out to the left of the oil cap thing on the engine? again not quite sure where it should go. gonna buy one tonight I think, so will be good to figure this out. otherwise might just have to pull a few tubes and stick it on one whichever one it fits
:D
 
The oil breather is connected to the intake manifold near the throttle housing. That is the only pipe that is connected at that point. Trace it back and that will be where you need to put the baffled catch can. You may need to be concerned about how to ensure there is a vacuum present where the vapours are sourced from so that the expected amount of pressure is present where it is required. This is all guesswork as I have not got it all figured out, however I am burdened with other things at the moment to look into this in much detail.

oil breather?? is that the tiny air filter looking thing? I have had one for a while but never know where to put it? what does it do and is it just a look good thing?? if the thing I have is what your talking about it would be great if you could share a picture so I can do the same

Thanks

Scott
 
Being an NA car, anything which dilutes the air mix less than as pure air as possible will reduce the efficiency of the combustion process. With forced induction cars this is a minor issue, however on NA cars this can make a little difference.

The other point is that the intake valves on the FSi do not have any fuel passing over them to clean them so anything you can do to keep the air free of oil vapour helps keep them clean and keep up their efficiency.

Scott, if you are about, give me a shout and I will show you where to plumb it in and where the EGR is.

yeah, that's the one...bought one today...don't know where to put it either. if you guys get together and figuer it out, plz put up a pic...will appreciate it a lot.

got an induction kit on tonight...woohoo. will put up pic soon. bit of a hash job on the fittings at present. it got dark out and couldnt see what i was doing :eek: much.

sounds brill though and could swear it gives a few more bhp at around 30-50 mph-ish at least.

next: more hoses and air in to point at it!

**Update** Having just driven to work for the first time with new induction kit...it was a good test, a few a/b roads and bit of motor way, have come to the conclusion it's not getting enough air...especially when moving off!

The default filter system is a closed system. am thinking maybe the air is being dispersed too much. Am going to try and close it off somehow and get more pipes going to it to see if that makes much difference. Hope so.

Will let ya all know how it goes.
 
The tube I have is plastic and I brought it from skoda and its of a skoda fabia 1.4 tdi
