RS2 ECU Upgrades

[S2central.net]

The whole MAF scaling thing is complicated... I'm not there with it all yet...

Paul:

Any chance that one can try out your V-stream RS2 chipset for a week? I'm having some problems with the boost and maybe it is the chips. It would be really nice to eliminate this as a factor.
Perhaps I could pay 350£ in deposit and then have the chips for a week and then return them to you if they dont work and I could pay you 50-60£ for that. And if they work I would just keep them.

Jonas....

The V-Stream RS2 chipset has NOT been tested by anyone yet... Actually its not even completed. As such it would only be confusing to try it on a car which might have some ills from a bad sensor or something. I'm not being unhelpful here - just saying that its too early to use these to help your boost problems. If you were local it would be a lot easier of course... Sorry.

Fair enough

Hi Paul

I have the ABY engine but with RS2 set up so should I go for the N stream now whilst you are sorting the RS2 V stream? The ncome back for the Multimode upgrade?

[Ducky]

I'd be interested in upgrading from the N-Stream to the V-Stream on my RS2 when it's available, going for a dyno run when I've sorted all the suspension out so be interested to see what gains it would make.

Calm down Rocco - its coming - its coming... including RS2 spec upgrades for 3B engines !

Just need more hours in the day

Now you are just dangling the carrot...Doh!

£450 seems very good value for two maps Paul Keep up the good work!

Any chance of a custom, or generic, 3071r map when you have time?!

Paul:

How much for just the switchable chipset device?

[S2central.net]

There is no such off the shelf device I'm afraid... its just the way I use different chips... Few straps and tweaks on the boards.

[Billman]

isn't 1.4 bar at 7000 RPM with the K24 7200 way of the compressor map overspinning the turbo? I am not sure that why i am asking.

[Jonas_R]

Well you must use something to switch between the chipsets?

Perhaps a picture and a component list to inspire me to make my own

[S2central.net]

I use a switch Jonas... The rest is not rocket science - just quite fiddly strapping up the board is all.

[Jonas_R]

So your using a PCB board with two eeprom sockets and a switch?

Or can one get some kinda exotic double eeprom socket?

Sorry for all the question Paul.

Hi Paul
RS2 V-Stream
1.7bar from 3000-5000rpm
1.5bar at 6000rpm
1.4bar at 7000
MAX Torque ~ 475-525Nm (TBC)
MAX Power ~ 350-380bhp (TBC)

Requires the following items on the car -

RS2 turbo
RS2 exhaust manifold (or better such as Wagner)
RS2 intercooler (or better e.g. Wagner item)
RS2 injectors (360ccpm at 3bar)
4bar fuel pressure regulator

As you know I have the MD147 RS stage 3 turbo, RS2 injectors, IM, EM 4 bar pressure regulator upgraded fuel pump and large I/C. Therefore, given my car is running rich on WOT (lots of unburnt fuel being kicked out on full boost) how rich exactly will you make it?
I need it a bit leaner than Mihneas chips without pinging. Is this possible? Or am I better off posting back the other genuine RS2 ECU (homefried) to you to remove the immobiliser ?
All help appreciated
Cheers
Karl
