RS2 ECU Upgrades

[s2bug]

Yea but is the N stream as mapped or just mechanical

so

Eco = mechanical
N stream = 350bhp
V stream = 379 odd

I maybe being dense here -- quite possible

[Sonic]

n-stream = normal homefry
v-stream (aka sport mode) = improved homefry
eco mode = a limit to either n or v-stream which limits boost.

Hey paul do you have anything that gets RS2 power from a standard s2 aby available Already Homefried to roughly 280bhp but as always.. wanting more

[S2central.net]

If you have the ABY N-Stream then you'll feel a difference going to V-Stream... More aggressive delivery and a bit more oomf up top - still not dyno'd yet. Running that with a RS2 airbox and RS2 intercooler is going to be getting very close to 300bhp... But you'll not get 'RS2 power' without an RS2 turbo - you canny change the laws of physics etc etc

[Rusty]

Well N stream + RS2IC was 297 so looking forward to V and X

[mcandmar]

There is no need for uprated rods with N or V stream... Obviously it is better to do that - but big money as you know. Max boost on V stream should be in 500Nm territory so safe for RS2 rods.

The intent is to make them plug and play... will probably have to err on side of rich to accomodate for variance in MAFs and such.

AFR shouldn't be necessary, but having one fitted does give you that confidence that all is well - though they can be a bit distracting on daily use. If you fit one bigger injectors then I could probably do some custom work to get the best out of your RS2 setup with even higher boost levels and the uprated rods you have - IIRC...

Sounds great, i have to re think my engine project now as i may as well start with the RS2 turbo :mischeif:

Out of interest how far away are these from the limit? i.e. if one were to go the tradition custom map route for a car with rods what kind of figures for boost and torque would we be talking about?

Cheers,

Mark.

can i just ask is the 4 bar fuel pressure regulator 100% needed to do the N Stream homefry? I have everything else except the fuel pressure reg as i am not aware first what it is and secondly that i needed it for the upgrade

[Al Wyn]

Steve your ABY should already have a 4 bar fitted

What about running RS2 MAF vs ABY/3B/AAN MAF on the V-stream RS2 chipset?

[S2central.net]

Sure can do - makes no difference - only that less restrictive mesh on the RS2 item.

Myself and others run with the RS2 MAF.

[Rusty]

I run an S2 MAF with on mesh at all! There is a debate about whether the mesh stabilises the flow but I've not noticed any running issues in 3 years...

[S2central.net]

BTDT too Andy... Once you convince yourself that the air filter can be trusted to stop small birds being sucked into the MAF its OK to run like that.

[Jonas_R]

Yeah well I heard somewhere that the RS2 MAF had a different voltage out put then the S2 maf.

[S2central.net]

Nope - but the RS2 ECU rescales the MAF voltage differently...

[Jonas_R]

Ahh oki that makes sense then. I heard this in regards to changing a sensor somewhere.
