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.

 

You dont need to run a knock sensor, if you want you can connect 1 up but it'll run as normal without it, if the chip is set up for closed loop then you can fit 1 into the downpipe and use the existing wiring on the 4x4 loom, no need to change the wiring at the tps if its a 4x4 loom and l8, just change the tps to a pf09

 

Is there anywhere on the 205 block that I can connect a knock sensor straight up to? I have a pf09 so I will use that.

 

Knock sensor just screws in the same place as on 200 block
