Alternator hooked up and it works!
Horn works
Worked out what wires go to the blinkers, ill hook them up tomorrow.
Headlights work
Parkers work
Bought a VL commodore TPS and hooked it up to the throttle, engine is a little happier now when i touch the throttle.
changed the gearbox mount because it was completely stuffed
Tightened the engine mounts
Tightened the sway bar
Routed the megasquirt loom into its final location
Getting very close to finished. Just need to get the wiper squirters going, zip tie the loom in place, scale the maps for a little boost and take it for a spin.

At the moment its running 5psi and it will stay like that for the break-in period. Theres still some fine tuning to go, i could pull some more fuel out of cruise etc but there is no hesitation or bogging anywhere in the revs and it goes as you would expect a low comp engine running 5psi would.
I'm very happy with how the megasquirt is performing, the tune is 100% better than the old microtech garbage already. It even starts and idles perfectly with no idle control.
When i wind the boost up more, probably around 12-14psi the full load afr target will be more like high 11's low 12's. I dont think theres any need to go that rich while only running 5psi on a low comp engine

I think the ignition timing will be the hard one to tune, i dont know a whole lot about it. For a base map i stole a boosted 4cyl ignition map off the 'net and pulled a few degree's out of the entire map for a little safety. I think ill need a dyno to really see the effects.

Today i worked on the exhaust. I installed a 3"x6" flex pipe, a 3" cat converter and a 3" hooker aerochamber muffler. I have a little more work to do, the exhaust is hanging too low. It sounds deeper and quieter than before, when reving the volume stays pretty well the same. Before it just got stupidly loud. Fairly quiet for a straight through 3" system!

Dash lights now work, the dimmer switch must have had some corrosion on it, 5mins of twisting it back and forth fixed that. Also hooked the boost gauge up to the dash lights.
Tacho is working. That one was easy, i just had to find the wire that connects to the - on the coil.
Alternator now charges (again!), the plug came off the alt. The spring clip is missing.
Jammed the MS and WB02 back in the glovebox for now, ill have to mount them later when i'm finished with the MS mods.

Yes, the exhaust is very close to the wheel well and body! I have to put a bit of rubber where it hits (when i start it, it hits) so it doesnt rattle :(. Its a HUGE muffler box, 3" of straight through goodness.

The real fun comes when i bump up the boost, i think another 10psi should make it more fun .

That would be baddd and expensive and i've already posted there once!
Lets hope the megasquirt will help prevent that, more control over timing should be a very good start. The last time it died i was doing 6,000rpm and boost spiked over 20psi (gauge goes to 20psi), static timing was 12degree's and im sure there would have been mechanical advance added to that, thats what im saying caused the last death anyway .

All i'm waiting on now is the drivers side seat belt my mate posted me from Qld, he posted it on the 16th and its still not here (stupid aus post ). I hope it arrives before monday, i'm running out of time to get this blue slip checked off :(. All this new suspension has made the car feel fantastic to drive, so much less sketchy and more predictable! I have some new sway bar bushes coming as well since there completely stuffed, hopefully make it corner better again .

Managed to get the megasquirt boost controller working tonight, without smoking the diode . Its so sweet, after a 5min drive we dialed in the boost and bumped it up to 10psi. Soooo much faster. Also bumped the rev limiter up a bit, 6800rpm soft (spark retard) 7100rpm hard cut. There doesnt seem to be much need to rev it past 6500rpm. I'm not sure when it hits 10psi but it holds flat all the way to redline! From idle to 2000rpm the solinoid is closed to help spool the turbo faster. Also gave it a tune, under full load it holds roughly 12:1 afr through the entire revs. Tomorrow maybe a little more boost and more tuning .
Bought a suction cup camera mount, might try and do a video at some stage. Put 450km's on the new motor so far

Heres another pic of the logs from a run. I dont know what that map spike is, i think its just a logging glitch.
