Buying an S2 Coupe - Am I walking into a world of pain.

From the looks of things that's all standard and has never been touched.

What I mean is back in the 90's or 00's, if you when into superchips for a remap then they modified the ECU & wastegate and unplugged the N75 valve. This there anything else they would have touched, as part of the remap?

I've sent a message to Newsh.

Is there anything else that gets modified, so far I've found the ECU, N75 & wastegate

Oh hell yes!
That's just the beginning.
Rods, EM, downpipe and exhaust, valves, coils, injectors etc, etc

And yes it kinda tried to push 3-3.5 bar into my engine according to my boost gauge. Went into "limp mode" 2 times before I understoud or saw what happened think it went ok, but still..

Lol… that was just incredible.

B5NUT, take solace in the fact there’s always some poor sod out there worse off than you!

Where the hell can I find a standard ECU?

Maybe your best bet would be to speak nicely to Newsh and ask him to 're load the original S2 map for you ( if possible) ?

I’d have a quick look inside first to see if there’s even a spring. There was a (horror) photo on here about a year ago of someone (apologies, can’t remember whom) who found no spring and something like a 24mm socket holding the wastegate shut.

That was me a Bahco pipe!

Now that, sadly will be a challenge.

I was saying to Tractor Dave the other day that S2’s are doing exactly the same as Ur Quattro’s did, in that people are moving away from modified and reverse engineering to standard. With our Ur we were lucky to find an unmodified ECU through someone else’s misfortune (car written off). All three Motronic 20vT ECUs I’ve got are modified and I can’t recall seeing a stock one for sale for years.

Well your wrong no superchip label

But you can see someone has been in there. Not f happy at all.

..... except yours will have a Superchips label fixed to it

[Ian Simmonds]

If you can picture this mounted on the back of the glovebox…





The ECU should slide out of the tray downwards (past the retaining spring clip).

*IF*?

You live in hope, clearly!

Passenger side footwell, behind glovebox. Remove lower glovebox cardboard trim and follow the wiring loom.

[Ian Simmonds]

That’s what Superchips did back in the day, they unplug the wgfv and wind the wastegate spring perch right in via that bolt.

And Martin’s post.
