Thread: Project LQ4 - V8 S10 - Sold.

Alright, even email me that file too.

I'm curious to see his work sometimes. I've seen a few of his tunes before and they seems to mostly be cut and paste type tunes because it does so many of them. Half the time I don't think he knows what he is doing and I see the same feedback sometimes on another forum I am on.

I can do that. I just need to actually drive over to his place to grab the computer. Probably over this holiday weekend.

Aren't most canned tunes just copy/paste?

More connections made; Heater hoses, brake booster, and the one and only vacuum line.

Started playing with the "rainbow of misery"

my brothers got a black bear in car tune in his yukon. it woke the truck up for sure. the trans tune is nice too, hit the tow/haul button and its a perf shift button now.

Yes they can be just cut and paste but when he offers in the tuning service with re-tuning ability where you log data for him and he makes corrections, that is where I see the flaws.

It's so easy to make a stock vehicle perform better, it takes all of 15-20 small changes to make that happen. Lower power enrichment enable settings, lean out the overly rich EQ ratio for WOT, remove some torque mngt, adjust shift pressures and small nannys like that. It's when people cam engines or do other mods like headers, intake manifold swaps is where I feel the job isn't done well enough.

Also the 4L60e has like 3 tables to change in the whole thing, shift time, shift pressure and torque reduction. I'd be scared for anyone that had a 6L80e or newer transmission tuned, they can be picky on nearly all changes made.

This is the kind of stuff I'm interested in. Really looking forward to when the truck is up and running and I can actually play with a tune.

Got some more parts today.



That allowed me to run the cooler lines to the front of the truck in anticipation of connecting to the radiator.



It's tight, but nothing touches. If it seems like I'm jumping around, it's because a lot of what I work on depends on the parts I receive. I didn't order everything in advance. I'm ordering things as I go. Kinda slows me down a little, but I'm not sitting on a pile of wrong parts, and it gives me time to research and reflect before every next step. Tomorrow I'll be back on the harness...

Nope. Decided to do the ignition and lock cylinders. Pretty soon I'll be doing a lot of key-on/key-off troubleshooting and I don't want to be monkeying with a fussy ignition cylinder. Old one came out without too much trouble. Old vs new



And back together. Nothing more satisfying than stabbing a brand new key into a fresh ignition cylinder, and this one didn't cost me a new car payment!



Then on to the lock cylinders. Drivers side was super easy. There's not much going on inside the door of a base model '97 S10.



And that's where my good luck ran out. I discovered why the right side lock cylinder was just plain gone. The whole handle is cast aluminum, and there's a little tab that retains the cylinder assembly. That little tab broke off and allowed the cylinder to fall out the back of the handle and into the door shell. The thing I can't figure out.... Where'd the lock go??? It wasn't in the door, and I didn't see anywhere it could have just fallen out. Did someone take the panel off just to retrieve the busted lock???

I'm inclined to believe you. Lol

So, it turns out S10 exterior door handles are dirt cheap on Ebay. Found a right side handle with lock from a '97. Buy it now price was $9 shipped. I offered $8 and the seller accepted. Should have it next week!

Wiring...

Spent a couple hours peeling this banana.



Extracting all the unnecessary wires, and labeling the needed ones.



C2 Block is empty. Feeling pretty good about this.



Also made a trip to the junkyard. Pulled this "harness" with 8 EV1 injector connectors for $13. I should be prepared for the eventual injector upgrade.



More harness work tomorrow...

Thanks! Kinda learning as I go.

I will be building a bench like that in spring once the grill takes a permanent home on the deck instead of the garage.

I love that workbench. Easy to build, and very little scrap when done. Takes a serious amount of weight too. Here's the plans:

http://www.familyhandyman.com/worksh...bench/view-all

I have been browsing for vices. Whats with the aluminum stock under the vice? How do you have it mounted?

Actually, that's just a chunk of 3/8" hot rolled plate. Local steel supply place had a stack of drops on sale for $13. I grabbed one thinking it would make a nice portable welding plate. The vise is just something I found on craigslist. Currently not mounted. I will eventually, but I've been doing so much cutting and grinding I wanted to do it outside of the garage to keep the mess out there. So I just set the vise on my workmate in the driveway.

im willing to bet its a mini welding table/ vice.

Why did you need an extra injector harness?

So many compaines make direct drop in injectors for LS cars/trucks.

Didn't really NEED a harness. Just figured it would be the cheapest way to get 8 EV1 pigtails. Eventually, I plan on doing an injector upgrade. Currently, my harness is set up for the Multec 2 injectors. I can get any kind of EV1 injector way cheaper than a Multec 2 injector. As I'm sure you know, the stock LQ4 injectors are only just over 25#. I was thinking of just throwing a set of stock GTP 36# injectors in for the time being. Even those would be more than 40% bigger, and I can get 8 of those dirt cheap!

Alright. I think I have it thinned down to the bare essentials. Still a lot left.



I guess you gotta start somewhere. So, I started with the injectors.



I'm really tempted to completely de-pin the PCM plugs and individually route each component. For $22 I can get over 100 of the female pcm pins, and I already have the crimping tool...

A few thoughts come to mind but I may have missed something along the way. Electric water pump? Smaller condenser? Is the engine as far back as it should be? Blah blah not much help. As a body man I gotta throw a flag on your vertical support... careful how you mod that. The latch position must stay intact and you mustn't lose any rigidity there. Needing to replace a smashed windshield and hood plus hinges would be quite a buzz kill. The point where vertical hood latch supports meet core supports is often overlooked but there's a lot of stress on that area during normal usage. Just bear that in mind.

More money.

Pretty much. There's really no adjustment in the BRP mounts. Even if there was, the right head would be into the AC box.

Not true. The comments get me thinking, and I like the input from guys with experience.

I appreciate your concern. It would be very easy to just hack away on that bracket to get the needed clearance, and not give it a second thought. I have a rough idea of how to add to bottom of the latch bracket so it reaches all the way around the bottom of the condenser to attach to the bottom flat of the core support. Should be at least equal in strength to how it was before. I think you'll like it. If you look closely in the last pic, you can see where I wrote down some reference measurements I took before disassembly. I tried to plan ahead so I'd have something to come back to.

As far as getting a different WP or condenser... It would be far easier, but I'm trying to avoid "custom" components simply for the cost. The stuff I have works, I just need to make it work. If I was running car accessories OR didn't want AC, there wouldn't be an issue, but I want my cake and to eat it too. I have a cut off wheel, a welder and Google. Anything's possible!

On a side note; Progress will probably come to a full stop for the next couple of days. My mom and dad are coming down from Michigan to visit. Pretty stoked to hang out with the people that gave me life.

you make it look easy some how, but all we see is the progress, we miss out on all the diagrams your following. and that head banging lol

Honestly... It really hasn't been too bad. No major hurdles. When I step back and look at where it's at compared to where I started, sure I've come a long way. Really though, it's just a matter of taking it one small step at a time to add up to the finished product. Like I say to the kids when they have a seemingly overwhelming task in front of them; "How do you eat an elephant?" To which they roll their eyes and respond "One bite at a time, dad." Then I say, "Start chewing sucker!"

Not a lot of that yet. I don't anticipate too much confusion until I start merging the two harnesses together. Even then it shouldn't be too bad. Just gonna take it one wire/circuit at a time. So far, my biggest frustration are those stupid fuseable links. They merge like 5 wires together so it's impossible to isolate one component. I predict I'll be burning through a lot of solder and shrink tubes.

I did drop $10 on some Ebay PDF factory service manuals yesterday. Should be worth the cost just for the wiring diagrams.
