Firstly - scan it with VAGCOM and see what the fault log says, otherwise you'll end up chasing your tail.

It could be anything, I'd put my money on a coilpack being on its way out.
Sideways yo!

Are you having misfires when your floor it ???

i.e over 5,000 revs ?


I've had no problems with my Pirelli remap from REVO for 2 months now...

I think Carl at REVO HQ had to mess around with it at first, but its silky smooth and perfect now happy2


I know the Pirelli map is different to the ED30 remap... so im guessing this what it might be...

If i was you, id get it remap at REVO HQ with Carl

vagcom  say misfire cylinder 3. had this always on 3, car is 2mth old 4200km.

coilpack swop and plug change new still same issue. it should not be coilpack or plug issue, i had a friend who is in giac tune with same issue misfire at WOT trottle high RPM.

so i wonder if its the tuning that is the problem, stock nv had misfire before.

i did read on some thread saying the valve spring is wrong ?

Hi there,

My Pirelli 58 plate did the same with a Revo S1, It was recored as a misfire but i don't actually think it did, just cam near it so the sensor used to throw the light on.

I had my code renewed with the latest Revo Pirelli edition software (apparently they have a sightly different rail to the Ed30 engines) and the problem has totally gone.

Mine only used to misbehave at the redline?

Cheers

Nos i guarentee you its the software 100%

Before i bought my pirelli 58 plate, i managed to speak with the previous owner... he said he had REVO remap and it was misfiring all the time when he floored it.. so he took it off...

BUT - REVO have solved this problem, they've bought out a REVO Pirelli remap ( which i got at HQ Revo in Northamtonshire by Carl ) which solves ALL the misfire issues.

I'm 100% positive this is your problem :happy2:

I used to have Custom-Code software on mine.

I still rate it, but it just didn't give me the aggressiveness that I was after, or the flexibility that the REVO SPS+ controller gives.

nosex, revo borrowed my pirelli for a week to log and tweak the map, it was constantly misfiring at 6,500rpm, its now done 6,000 miles mapped and no issues

the misfire has also affected some Leon's and S3s

my car is going back into revo after its first service (which is due soon) to try the original map soon

it would appear you can't assume a Ed30 map runs on a Pirelli

To the OP what fuel are you using?

Cylinder 3 is the normal weakspot as it is either the longest or shortest intake path.

for revo stage 1, no hardware needed
