RS2 ECU into S2 Loom?

[RS_Rayver]

Hi all, I'm currently in the process of fitting an RS2 engine into my S2 coupe but dont have any of the RS loom or ECU. Can an RS2 ecu be used with the S2 loom? If not, can the S2 ecu be remapped upto RS2 Spec?

any help will be greatly appreciated,thanks for reading,

Ray.

What engine you had in your S2?

[RS_Rayver]

the S2 engine is an ABY and the RS2 engine is an ADU.

Then...the engine looms are identical.
Goodluck!
You need to install the rs2 engine and rs2 ecu on your existing loom.

[Pirvu Eugen]

You can remap your ABY ecu to rs2 spec.
Search the forum for the tuners wich have done this!
Success!

Thanks very much, I'll have a look at the threads regarding tuning the standard ABY ECU up to RS2 spec and decide which is the best route. Thanks again for your help. :-)
