You'll want to keep running with the auto ECU after the gearbox conversion.

After mine was coverted to manual I bought a manual ECU off eBay and gave it a go. It ran the engine exactly the same but suddenly the TCS and SLIP lights were constantly on, plus no traction control. Apparently the TCS sensors differ between the auto and manual cars.

So in summary, running the original auto ECU is what you'll want to do. The A/T light will illuminate on the dash because it can't find the auto gearbox but you can remove the bulb in the cluster if that bothers you. Better than having no TCS!

    • Getting Dangerously close to being ready to go back in the car. Rockers in with clearance castings now (and a quick check with the USA for the torque settings for the larger custom bolts) Covers and ported FAST Manifold sitting on there. Not fully tightened down as there's some clearancing required for the water pump with the earlier LS1 water pump styles. Example of the clearancing needing to be done: The body has to be ground a little but I'm struggling finding an actual piece of it. The later variant of water pump resolves the issue as the manifold was designed around it. It only came on the VZ LS1 in Australia, it got a different pulley for Gen4 motors. (it also costs $450... vs... $0).

    • Doing some height adjustment on front suspension on a v35 and noticed this. The passenger side looks correct. So wondering what's happened to the drivers side?
    • Oh...I have the electric mirrors as well iirc ...they're in the same state as just about every other R31 door mirrors, with the 3 plastic screw towers broken/cracked in the plastic molding. All the interior is 'dry', so the mirror switches etc likely all work fine. Some pics below of the trimmer pieces ~ looks to me like previous owner, painted chrome finished trims with black paint ...ergo, the chrome underneath is likely a-ok... ...starts to look yukky posting stuff like this, how much did it cost in fuel on your last sortie up this way?...me just thinking aloud, borrow someone else's 4cyl to cut costs, come do your own pick'n'pull like before to save me some bother...hehe.. but whatever, I'll just earmark bits I know you want, because the way this is all panning out, I'll be able to retire the R31 from daily duty at long last, replacing it with a Subaru wagon I'm lining up in the wings...ergo, my attitude towards the donor pinny shell is starting to wane a bit, and I'm more than happy to help you out there... Like you say though, no rush...and I'll guarantee we won't be moving too far from this locale at any rate 馃槑
