Well my fueling issue was as expected, no actually a lot worse lol. I pull the injector numbers off them and found that I had 15lb injectors in there somehow.
Yesterday I found my stash of injectors finally and so I started going through them. I got a nice range. Everything but what I want. I am looking for 30-40lb high z injectors. 45lb would be about the biggest I would put in there.
That are even in a possible range to use... I got a set of 23lb, 24lb, and a set of 30lb. But the 30lb are low z.... I can get a set of 60lb later today. But those are likely going to give me idle headaches.
I am running a 4 bar pressure regulator. So that bumps each injector value up a little. Its good for about 3lbs extra on a 23lb injector and about 4lbs on the 30lb injectors. The 30lb ones would be perfect, if they were high-z....
I don't like running low-z injectors on a MegaSquir V2.2 ECU. While it can be done, its not quite as reliable. And its a bit of an initial tuning headache. To do so reliably, a flyback or peak and hold board need to be installed.

We are running good and stable now. Ready for safety and emissions. Except for a really bad oil leak, and an easy to fix but bad fuel leak.
Couple oil leaks, but the big one is out the filter flange to block. I hate the fiber gaskets on these older engines. The ABA get a nice metal gasket. I also have a leak near the rear main seal out the oil pan gasket. itsmissing the bolts there as my flexi 10mm socket is MIA. Easy fix.
Fuel leak is also an easy fix. I only had three sets of injector seals. So of course its leaking out the last injector...
Hoping to get some of the instructional videos taken over the weekend. I need a way to take video of the laptop monitor. Like from inside windows... Any thoughts here?

Leaks are all fixed and shes driving now. I have a god awefull noise coming from the left side though. Could be a bad axle, less likely a bad wheel bearing. And possibly a few other things.
Wasn't comfortable going further than around the block twice until this noise is found out and either discounted as nothing (doubtful I will get so lucky), or fixed.
Brakes suck without the booster hooked up. I am going to have to attack that before driving her again. Easy enough though.
Tranny feels weird too, can't determine if shes moving away in third gear or first. Tuning right there defiantly isn't even close to dialed in.

WOW this is one angry. PISSED OFF little bunny!!!!
The brakes suck without the power booster hooked up though....
As for tuning, not even close yet. I can only imagine once its all dialed in. Not sure whats going on with the shifter... Seems as if its not adjusted right yet. I don't think I am getting it into first. Haven't drive her too much, but most of the starts are difficult like a third gear start. Then there was one that just had her launch hard squealing tires all the way into second gear with zero traction.
The worst is over though. Monday should easily see her ready for safety and emissions.
Safety requires all the lights working. Here in Utah for some reason I don't have to have reverse lights. Good thing too as I got to figure out the correct pins on my plug there... Almost everything else is basic things. Parking brakes, check. Headlights legal and aimed, check (for now lol). Horn, check. Wipers, kinda...
I only have a few small things to deal with. First off all my dash wiring needs to be tucked up and away. Not a safety as much as a practical thing I guess. But for safety I need my wipers sorted out better and the washer isn't working. . Wipers were working, but I cut the wires to reroute the plug differently. I haven't fixed that yet as I want to just put in the upgraded mk3 motor anyways. Hoping that reinstalling the wires there sorts out the washer.
Another surprise was I need my defroster working. Thats a little harder to manage as all that wiring was missing. I have what I need to redo it, but its a couple hours of sorting it out, changing the blower box most likely (has a broken bottom vent) and other random monkey business.
Emissions? For a car as old as this I am not required to have a cat. I also don't have to blow super clean. We will probably tune it much cleaner than we have to though. The Mad Scientist and I have tuned many a car on MegaSquirt to fly through emissions. Usually I can tune a car even with an empty cat to blow as clean as its supposed to.

Passed both emissions and safety without too much problem. The car was far from close to being dialed in on emissions... Took The Mad Scientist a while to dial in those areas. But I had zero tuning in on her too.
Last night we managed to process a few datalogs and dial her in a bit more. Shes already running hard!!!
Not really a lot of interesting pictures to put up right now. The biggest hurdle in this was the not expected issues with the gastank. So far, no cutouts in hard cornering. Hard to tell though as there's some gas in the tank too. But I suspect that installing this little gem helped immensely.
It took a few tries to get it right, and get everything tight and not leaking. But a half tank fill up yesterday seems to be leak free finally. There was a few other minor issues. No way a button head bolt would have given me enough clearance on the serpentine belt. I had to take everything back out and attack the frame rail with a hammer again to get enough clearance. First start up had it bouncing off the frame.
Next on the agenda? Probably going to mostly just drive it for a few. Theres lots of small things I have to finish up. The OE engine bay wiring and rats nest under the dash being the worst offenders. Got to work on getting the videos made and online. Lots of little projects here and there. Todays will be getting the wiring around the fusebox cleaned up some more and working on setting my lights up the way I want.
Lol what side?
What the local mechanic will do differently is reach into his tool box for his Snap-On wrenches. Hes going to use some line wrenches first. Line wrenches could even be good craftsman ones. But seriously 90% of the battle with stuck junk is to use HIGH QUALITY wrenches.
I ask what side, because I couldn't get the passenger side off, and I had them off a week before. Most of the reason here is likely simple, too much tug on the line from the axle. This time around I was able to get enough room to pull the tank simply disconnecting the drivers side and dropping the axle out of the way as much as possible.
The other secret weapon I use? PB-Blaster. Forget WD-40 for a job like this. PB-Blaster gets in and penetrates a LOT Better. I also take the time to prepare for the job as much as a week in advance ESPECIALLY on brake line connections. I soaked the joints multiple times starting about a week before. I HATE frozen brake lines.
Do yourself a favor and get a new filler tube to tank line... The old one will almost defiantly leak.
So in summary, soak with PB-Blaster and get line wrenches. Don't cheap out and at LEAST use Craftsman ones. Use high quality wrenches for the rest of it. I used Craftsman line wrenches and Snap-On stubby wrenches the last time. Oh and be prepared to have to fiddle and move the axle around. Use a good floor jack and get the car up as high as possible on GOOD jack stands. I left the front on the ground to get more rear end clearance.
Finally? Take your time. I was a professional tech for years. I had to walk away a couple times on this one.
Priorities are sorting the OE wiring. Getting some upgrades in, finalizing it all and heat shrinking the rest of the engine bay. Then I need to get my water injection online, alarm and radio installed and finalize all the interior wiring.
Brakes are a big issue too. Feels like my booster is bad. I have almost zero booster assist happening for some reason. I need to figure out that and maybe get the upgraded brakes onto her. Soon as thats sorted out, we will be finishing up the suspension. Probably dropping her some more and then putting some extra goodies onto her.
