seeing that i need a bac to control idle better. will a bacv from an s4 interchange with an s5 one? like, bolt up to the uim? i dont have an s5 bacv to see if it plugs into the s4. so im kinda wingin this one lol

i have a s5 engine with s4 electronics(engine harness + ecu). wanting to know before i go to the junkyard to pull it, instead of pulling it and getting my hopes demolished when it doesnt fit/work the way i wanted it to.

 

I'm not sure but I think the mounts are different between them..

As far as the wiring though, they're mostly compatible [you have to modify the connector, and extend the wires]

 

hm... how about between the s5 na and s5 t2, are they the same as far as mounting points go? i mean, resplicing or repinning isnt a problem really. i have enough of that goin on as is lol

 

No, they aren't.

 

that blows. time to go into the FS section i suppose
