[s-cars] RS2 ECU for sale

[Keith Maddock]

Scott:  But if a person already has a RS2 MAF/FI/FPR in his AAN car, then it seems this ECU *is* plug and play.

Here's my understanding from what I have heard from all the posts:

Stock RS2 ECU in stock AAN = NOT GONNA WORK
Stock RS2 ECU in AAN w/ RS2 MAF, RS2 FI's, and RS2 FPR =  PLUG & PLAY (non MS definition!)

RS2 ECU with AAN Chips (regardless of stage) = NOT GONNA WORK
AAN ECU with RS2 Chips (regardless of stage) = NOT GONNA WORK

In the end the CHIP software has to match both:
1) the ECU that its going in
2) the MAF / FI / FPR on the engine

So if someone already has RS2 MAF / FI / FPR, this will work.  However if he wants to upgrade his software later, he is going to have to use RS2-ecu software *NOT* AAN-ecu software.

I'm not going to offer a judgement for anyone to buy or not buy this part, as I don't know what the market price is for these things, AAN or RS2...
But if someone has a AAN with all the RS2 bits already installed, then this ECU will work , but possible provide a more difficult SW upgrade path in the future.

Hmm, gee bob, maybe my point wasn't clear.  You advertised for another guy
that his RS2 ECU is for sale for 900USD.  Soooo....  We now can agree that it
won't bolt into the AAN and run correctly.  Which means that one needs to
remove the RS2 chip, and in stall the AAN chip, more specifically, an AAN
coded chip.  That's gonna add a few hundred to the price.   See where I'm
going?

Bottom line:  I'm seeing the original post, thinking someone's gonna buy an
expensive ECU, plug it into their car, and it just won't work.

So I guess I'm just making the point that this just might not be such a great
deal, and someone (like the seller - or someone) should point out that "plug
and play" needs a lot of hardware and/or a lot of software associated with it
to make it work in an AAN Scar.

Thanks

The whole point here, which apparently isn't clear, is the ability to use an
RS2 ECU (complete ECU, not just the chips) in an UrS4/6 that has had the RS2
hardware installed.  I would think the only "gotcha" would be if the pin
outs are wired differently between the respective cars, and from what I'm
hearing there is no difference.  Of course using an RS2 ECU in a stock AAN
isn't going to work.  No one is advocating that.
