RS2 ECU Upgrades

[kwlw]

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.

Jonas, don't overcomplicate - there are bigger eeproms (internally), and you just switch high address bit with the switch. I mean you have two maps in the same chip, which looks almost exactly the same as original ones, except few pins may be hanging off the socket. Switch is wired to those pins, and that's it (if you have 3b). With AAN/ABY/ADU stupid 87c257 eprom there's more PITA to do that.

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

Bump for Paul (S2 central)

[Alistair E]

Well the car's rebuilt and now running one of Paul's multi-chips. Haven't sorted the switches for the valet and v-stream, so currently running stock RS2. Car is definitely quicker than S2 homefry but the biggest difference is how smooth it is. I haven't felt the rush of acceleration like there was before when the turbo kicked in. Also, the hesitation that was there around the 4-5k mark has disappeared.
Had a bit of a go at a 51 plate M3 last night. Nothing in it 1st and 2nd. Had to back off as there was a car in my lane, but when that cleared, he had a bit more than me in 3rd. Gutted that I hadn't sorted the switch for v-stream. Switch ordered first thing this morning.
Clutch is smelling a bit after a launch, but I suppose that's to be expected.
Anyway, cheers Paul.

Tighten your seat belt then before wiring up that switch

For us foreign folks, does that specific licence plate indicate E36 or E46?

e46

[S2central.net]

I have no idea what that means... Beemer jargon that is

Im trying to decide between an e46 330ci and an e46 m3

BMW E21 - (1975–1983) 3 Series
BMW E30 - (1983–1994) 3 Series
BMW E36 - (1991–2000) 3 Series
BMW E46 - (1998–2007) 3 Series
BMW E90 - (2005–) 3 Series Sedan
BMW E91 - (2006-) 3 Series Touring
BMW E92 - (2007-) 3 Series Coupé
BMW E93 - (2007-) 3 Series Convertible

Bet you never thought you'd see that on the s2forum, did ya?

Sonic - you have sullied the forum - I am disappointed in you

arrh my eyes hurt now. those should be added to the swear filter.
@ paul any closer to doing a 3b switchable home fries yet. i want to try something different to the mrc ones i have at the moment and don't want to waste money on a mtm one if there is going to be a home frie soon to be avalible.

OMG i feel violated.... get that Beemer data off, or go sign up on a BMW forum and list the audi model years and types pronto!!!!

get either a m3 or e30 325i touring for proper drivers car action, I must say there are only a few beemers I like main thing to remember is early e30/36 beemers rust for fun, be carefull, if you find a good one you will be rewarded

Yes - 3B switchables are go... There might be lil tiny tweaks from now on, but I am happy with feedback so far. Two maps - hot switchable - say factory plus N or V stream variant... or N & V in the box. Plus a 3rd mode that disables active boost for valet/eco mode.

Pricing includes a 2.5bar MAP sensor upgrade.

£250 for N
£300 for V
£350 for switchable factory (rescaled for bigger MAP) plus N (or V) plus valet mode
£450 for N plus V plus valet mode

Send me a PM if interested.
