As above I have recently bought a 2wd Saph, but I have an L8 Ecu at home and also a brand new MSD 4x4 loom (all intended for my 4x4 saph before deciding to go a different route). So my question is, can I simply remove the old loom and ecu, put the new loom and ECU in, swap the TPS over from the 4x4 and then put a lambda boss in the down pipe?

Also what do I di about the 4x4 loom having a knock sensor?

Regards, Kieren.
