I notice stage 2 and stage 2+ actually make less power than stage 1 before about 3500 rpm.

Does this back up the theory that an after market intake actually lowers intake pressure so the turbo doesn't spool up as fast.

It certainly felt 'flatter' at low rpm with my itg fitted to my stage 1

I was stage 1 on my Edition 30, no mods - got 289bhp on JKMs rollers, had a 3"DP and 200 Cell cat and ITG panel filter, felt quicker but flat through mid range/top and only got 272bhp... Was obviously retarding timing, and would have been even worse with an CAI on... as it requests 130bar on the pump, which the oem throws it's dummy at..

Full BCS cat-back on top, APR HPFP and EVOMS and on B8T5F7 i'm only getting 309bhp... but does like to rev right through...

Nice to see Revo come back and answer the queries :)

Our software revisions have been tested on all variants of the 2.0TFSI K04 engined vehicles, the graphs were from an ED30.

We recommend using an up-rated FMIC in order to use full boost potential and not see excessive heatsoak, regardless heatsoak is always more prominent on a rolling road.

A HPFP upgrade has never been a requirement for Stage2 software. Revo adjustability is designed to allow the vehicle to be setup to maximise the potential of your car in the given conditions, fuel quality and for the hardware modifications and incorrectly setup car is never going to be 100%.
As per the original post new Stage2 software is designed around the limitations of the standard HPFP.

You can reliably run Stage2+ without an intercooler upgrade, however it is advised to run lower boost settings to prevent excessive heatsoak.

Dyno's are indicative at best, there are numerous factors that effect a power curve. Loading of a car can affect the initial power/torque curves. Stage2 software doesn't make anymore torque at peak than stage1, the torque curve is different due to HPFP limitations. Most breathing modifications 'move' torque up/down the rev range, without an intake or turbo back exhaust upgrade the midrange and top-end would be massively limited. To give you an idea on these cars an intake can allow for around 0.4bar more over approx. 5krpm to redline if the car is setup correctly.

Get you cars updated and Go Play!

Any updates for a AXX ECU running a BWJ Cupra engine?  :smiley:

Over the top mod list ;o)

Well I'm booked into HQ for jump to Stage 2 map so will see how that does when I take it back to SRR for dyno'ing.

Kinda like my stage 1 set up though  :smiley:

Will the settings stay the same? As mine was set up on a rolling road(by JKM) and my local Revo dealer (VAS Works) doesn't have a RR...

Cheers.

I'm expecting Kev to change my settings to allow the engine to perform at its best / most efficient! (I want some extra mpg too lol)

So have Revo just lowered the requested Fuel pressure back from 130 bar to 115 bar on stage 2 to stop the fuel cuts issue, so that the OEM fuel pump can cope?..that's what it sounds like.  :confused:

You can reliably run Stage2+ without an intercooler upgrade, however it is advised to run lower boost settings to prevent excessive heatsoak.

Surely stage2+ with boost turned down is not going to be any better than stage 2 with the boost set to the highest before heatsoak becomes an issue?

And as steve asks, have you now reduced the requested fuel on stage 2? Surely less fuel, means less air required to get the mix = less power?

Personally I just want the best map for my hardware, and thought I had it, but this has left me all confused...  :sad1:

I think so yes.

Seems to pull harder in 6th gear 80mph+
Mid range power seems improved.
Seems to be a bit smoother, but not lacking punch.
DSG pop seems a fraction louder (damn i want a TBE), maybe as a result of increased boost pressure.

I need to log the g/s with VCDS, and also hopefully get it back on R-Tech Rolling Road (where it has been on before) to see whats happened.

Email to JKM tomorrow then, see if I can tie it in with a service... looks like 2+ might be on the cards if Revo can convince me and JKM say it's wise...

Those graphs are a bit paintshop though, and my stage 2 isn't making anyway near that... maybe the dyno lottery of course...

What what ive heard about all stage 2 maps i wouldnt bother with it. If I could afford it and wanted to do it, I would go straight to stage 2+. (Thats unless this update fixes the dip in power in the mid range)
