Gday as the title says, is it possible for a series 1 engine loom to be fitted to a series 2 engine? And a would a power FC tuned for the series one engine be OK to fit with the loom to the series 2 engine?

but the plug to both CAS are the same, so just use the cas for the motor you are using. it is all interchangeable as long as you use ignitor and s1 coils, or just s2 coils.

sorry I wasn't clear. You use the stuff that matches your engine loom so yuo have the right plugs for ignitor etc. But it doesn't matter if the motor is from s1 or s2 as long as yuo change all of your old bits over.

i did the opposite of what you asked above, s1 engine in a s2. kept the s2 coils and it was all fine

and the computer is the same for both to answer your other question.

be sure to note AFM setup is different

S1 is 4 wire AFM

S2 is 3 wire AFM

its the same phyiscal AFM , just S1 has ground and signal ground, where as S2 shares 1 ground

    • Hope your all having a mean Xmas! If anyone happens to know any trick to using the insanely complex climate control system, I cannot get it to not be on dual zone no matter how many times I deselect it (will say it's not but both vents blow different temps). Also one side is always hot, one always cold 🤷
    • I'd be looking at the mentioned EFR kit, room to turn it up if decide on e85 (which we know you will) and be super responsive and fun on the street. OR https://v8roadsters.com/product-category/engine-conversions/engine-conversion-lsx/engine-conversion-lsx-nc/?srsltid=AfmBOorrJa2S76JR5ekXprxBOtU44a1UProbe64YaiVi9zTVp1Lj814w And add whooshy noise for extra fun C5 corvette prices are coming down locally here and a mate has a manual one and is a heap of fun on the street and track.
    • I have an Elite 2500, honestly most of this has been a lot of smaller tasks chasing little details and a whole lot of life getting in the way of bigger projects. I don't mind too much looking at a spectrograph vs having audio knock ears. 
    • Nah nah nah nah. Don't do it. It's not all about the full throttle power delivery. The main "street fun" and drivability gains from smaller rear (in this case) is how you will have boost available from a low rpm when yo just roll onto the throttle. Think jinking in and out of traffic, coming out of roundabouts, etc etc, where you just want to roll onto the throttle a little and have the spooly noise from ~2000rpm and a swell of torque. More of what you've already achieved by going to 2.5. And then, towards the tail end of 2025 you can pull the turbo 4 out and put in a V8 like we originally suggested. :P
