revo stage 1 in a VRS and misfires

[George Dim]

I revo'd my Fabia to stage 1 performance 2 (98ron) and since then I got misfires in high revs (6800-6900 rpms) in 3-4th gear.

Before getting the software I was free of misfires.

Does anybody have any idea?

[stu_mcl]

Is that after a long journey sitting at a constant(ish) speed? If so they all seem to have a slight missfire if you let it rev after that......or atleast mine does and one or two others im sure

"Before getting the software I was free of misfires"

Think you just mentioned the reason in your post. :p

Few Q's.

1- What year was your engine constructed. (there should be a plaque/sticker on the engine which says the date of the engine)

2- Are you running standard plugs? If not try upgrading to NGK BKR7EIX plugs and reduce the spark plug gap to around 0.65. This is what REVO recommend.

3- What fuel are you using

I bought the car April 2011.

Standard plugs.

Id try different plugs as a first port of call. Before the remap had you been to your local skoda dealer and had the latest update to the standard software?

Nope I am going on Friday morning.

What is the original gap of the NGK BKR7EIX?

iirc mine were around 0.68 ish so i only closed it a minute bit more.

I'm sure a lot of members will be interested on your findings from this. Although the revo dealers I have been in talks with have all recommended having the plugs changed as a minimum requirement. Hope you get it sorted

Isnt BP Ultimate only 97 Ron? It certainly is at our local station. If so, couldnt this be part of the problem?

[P1TT8ULL]

The normal super is only 97 but some BP garages do 100 and one near me does 102 but its locked and you must get a key for it

If it is, Skoda can stick my VRS where the sun don't shine !

Q - I see you're interested in the VRS Fabia ?

A - Yeah. Like it a lot.

Q - Where do you live ?

A - West Cumbria

Q - Sorry, there's no 98 RON fuel around there,

only 97. The car will have all sorts of issues.

A - Thanks for letting me know.

:think:

Don't get Skoda to reflash ECU if you have a map in it!

Reflash wipes the control unit completely......inc your remap!! ;-)

Which is also west Cumbria? Lol saying that it's sunny here in south lakes today B-) haha boom!!

[leevrs180]

ive run standard 95 since brought no problems of misfire well apart from cold, and high oil usage 1ltr per 600 miles.

And i only have access to 95 due to where i live

The BP garage a few miles down the road used to do the 102, not anymore, closest I can now get is 99 from tesco !

[MillsyVRS]

is the 102 a bit much for road cars? read it was only really for racing? or would it be ok? and i'd imagine it would be at least £2 a litre wouldnt it?

True but any reputable tuner will put the map back on free of charge or for a small fee

[P1TT8ULL]

Was about 2.10 last time i went past making it about 90 quid a tank

[George Dim]

Yesterday after 500 miles journey no misfires even at top speeds 245km/h!

Waiting for update check up. I fueled from a different petrol station.

[George Dim]

Still free of misfires since I fueled up from a different station
