Re: Datsun 240z with L20ET
We spent some time on this today, got the right base tune installed, tweaked the injector rate a little, fixed up the thermo fan (found the relay was wired to gnd instead of B+), and found the alternator was dead... it still needs exhaust and some tuning (what its got was best guess without trying it), but I wanted to put some video up here showing its alive and is ready to run!

Re: Datsun 240z with L20ET
Its capable of idling between about 950 & 980. It was idling at 1500 first try, but we found the air leak That vid is higher as its a cold start and needs a tune. Earlyer in the day we let it warm up and thats when it happily sat at those rpm with about the right AFR. I'll update this thread after we dial it in a bit better.

Re: Datsun 240z with L20ET
We'll have a go at it this coming wednesday if things go to plan. Still have to replace the alternator and install an exhaust, so that could take the whole night after we get home from work. We'll see.

Re: Datsun 240z with L20ET
Swapped the alternator. Still not seeing more than 12v at the battery. Not sure if its a wiring issue or 2 bad alternators. Got most the exhaust on but then got rained out on that. Tweaked the tune a little, set all the warmup IAC steps to 0, as we have no speed signal yet so dont want to use the IAC as the car will never go in to idle mode, so that solved the high idle at key on for now, but its more of a hack till we do some more tuning and install a VSS. Thermo fan is working properly, it warmed up to 87ish degrees and clicked on, which cooled it to about 80 and it clicked off. Then removed a little AE because it was over richening when we gave it a rev so now it revs cleanly, but we ran out of time for the road test.

Nice one
Got a charge light on the dash for the alternator? Need that to tickle the insides of the alternator to make it charge.

Re: Datsun 240z with L20ET
how many terminals are on the alternator one for the big charging wire one for charge light and is there one leftover to goto the battery to tell the alt the charge rate at the battery like a vn alternator
If Its Got Gas Or Ass Count Me In.if it cant be fixed with a hammer you have an electrical problem
