Hi guy my friend who is also on the side has a 2007 vrs se and i have a 55 plate vrs it seems his has alot more power at lower revs than mine which picks up ok but pulls more powerfull around 3000rpm or 3500rpm ??

[Ashby14]

Could it be due to things such has his egr valve is a different style or something like he has a more modern map due to a newer car sorry im not much of a mechanic but if anyone has a good idea that would be great

[vrs'burks]

engine was all same i believe (blt) urs may be an asz code engine. . not that i think it makes much difference

,think the gear ratios were different on the older ones,that'd explain it.

[Ashby14]

Im sure mines a asz but seems strange

[Ashby14]

Would that egr of that blt model fit a asz as my egr is leaking and it seems a common occurance on the older style egr

[vrs'burks]

only difference on asz is Summat diff with the egr system.

as i say earlier ones had a diff gear ratios. .

[vrs'burks]

if urs is asz do an egr delete,easier to do on asz. n on blt it throws eml light on which has to be mapped out.

[Ashby14]

Ok im so rubbish mechanically minded and couldnt see what i would do with the bits attached to the egr does it turn on the eml light ?

[vrs'burks]

if you had an egr delete on yes but it can be mapped out on a asz. . .not the same case with blt's

[Ashby14]

Oki doki ill look into it is it straight forward

[grr666]

BLT engines which are the later variant are more powerful than
the older ASZ engines. They have been recorded at over 150bhp
with standard mapping. The ASZ tends to produce about 140bhp as stock.
His later car may also be remapped, just because he didn't do it doesn't
mean it isn't there.
By now there can't be that many of these cars left running standard power.

[mattievrs]

The asz engines made around 130bhp as standard whereas the blt engines were found to make around 145bhp as standard. This could be the answer here, they both remap to around the 170-175 mark aswell.

[Ashby14]

Mines standard not mapped neither is bis but there equal when weve had little races

[grr666]

That's my point, he may not think it's mapped but it might be.
Mine was when I bought it. I genuinely thought it wasn't until I got
it on a rolling road to be certain. I got the figures in my sig so definitely not standard.

And I took a drive in another members "standard" car a week or so ago
and I'd bet my last fiver his car is mapped as well. Shame really as he was
about to get a remap to spice things up a bit.
I had a little run out on the motorway with him when we first
met and my mapped car could keep with him but I'd be lying if I said it was a doddle.
I remember thinking at the time that his car was rather swift for one in standard tune.
Now many months later having driven it myself, I can understand why he set such a
pace.  Hard to explain but they drive more like a petrol car when they've been mapped well.

Standard cars are a bit flaccid in the higher revs whereas a well mapped car will pull
pretty hard right up to the redline. Having just gotten rid of a pretty high revving MX5
recently I've got to say I've missed having a proper redline. Next car will be petrol turbo
for sure.

[Ashby14]

I brought mine from a old guy who had had it from new all reciepts genuine from skoda i really cant imagine its been mapped lol

[grr666]

The last "older" guy I knew personally who had a Fabia vRS was a chap named
Bernie. A fully fledged grandfather he was often seen showing the younger guys a thing
or two round various race tracks in the UK in his slightly modified Fab.
He's got a mad little yellow Westfield thing now, the Fabia was too slow for him.
(He also ran a Clio Cup at the time)
His username on here is Sootie. Just cos you're old, don't mean you can't be old and fast

Sadly, I turn 40 next birthday and as part of my midlife crisis I'll be off to buy an Audi S3 when the
right car comes up. I've been looking at them for months but the right car just hasn't appeared yet.
I'm off on my honeymoon for all of September so unless one comes up real soon I'll have to
get looking again in October. Probably for the best to give it a chance for some new ones to
go up for sale. I have a very specific taste and will wait patiently until the right car becomes
available.

[faboka vrs]

Their mapped differently.

I downloaded a standard BLT map from a guy in works 56reg.

[mannyo]

The older cars also have different gear ratios to later ones, this will make a difference as well. Drive at 70mph in both and you'll see different RPM readings in both cars.

EGR delete will require a remap anyway unless you like to drive around with the check engine light on.

[Ashby14]

I dont mind getting a egr delete and remap but is it worth it ive heard it just destroys clutches and that probably explains why his spins up so easy compared to mine which dont unless i drop the clutch which i wont do

[DRJ]

Please note all the responses re different gear ratios are irrelevant to the OP's question. The gearbox ratio change occurred early in 2004. The earlier car here is a 55 so will have the same gearbox but a different engine as noted...

Depends on how much extra fuel is injected low down. It's very easy to limit the torque low down. I'm on 112k miles still on the original clutch.
