just another Chevy ... the s10 DD

you know there are ways of getting inspection stickers for your truck in texas without dealing with all the political bs drama, trust me i know this LOL

I have a sticker for a Fiat that runs just like a Pinto - not sure what you mean? I worked with an inspector once that failed a car because it's brakes were so bad it ran into his toolbox. It came back in 20 minutes later (pushed it in) with a 50 on the steering. Sumbich passed, can you believe it?

It'll pass. I just discovered you can flash a v6 computer to run the v8, and it needs a few wires moved around to get the injectors firing order right and a couple extra for the two additional injectors. Far out.

[SuperBuickGuy]

just as easy to swap the computer - no swapping wires, no drama at all - use the 4.3 wiring harness.... I suppose now's the time to mention that the last s-10 v8 swap I did, I had a plug and play motor for smog out of a 93 chev truck; and the "other" motor for the other 729 days.

SBG, thank you for the input. I don't want to sound like I'm being petulant, I appreciate the feedback. Although I would never admit to any "other" engines, it'd be 364 here. We're annualy anal. We smog, we put the county it was inspected in on the sticker, and if it doesn't match the county it is registered in, they give you grief. Worse? I want a Ford engine in it and I want it to look so factory that the oil change guy doesn't even blink. There are a couple of hangups with doing that. Knock sensor, crank trigger wheel, and cam locator sensor are currently topping the list. An LS1 (geniii) has these internal, the Ford's are external.

I spent way too much time yesterday trying to figure out if HPTuners or any of the other editors out there could handle a Ford crank wheel and cam position sensor, whether the s10 tailshaft on an s10 with VSS would work and where to find one, low impedance, high impedance injector foo, seeing what the MAF was good for on the 4.3 before saturation, hacking LS TB onto Ford manifold or just hope that 0-5 means 0-5 in all languages.. my head hurts. Some days, it just isn't worth the effort to chew through the restraints.

It was kind of an excercise in futility but it was scalding outside and I've run into other issues with putting an A/C in the garage... like something fried my circuit and there's no way in hell I'm going up in that attic until October. I don't question what electricians charge down here. The cable guys are getting screeewwwwwwed.

I'm leaning towards an HPTuners suite at this point, there are several things I want to turn off in diagnostic test, function, and error reporting. I feel like I'm being sucked into the car computer junk the same way I did PC's 25 years ago. It's hard to remember "This will do everything I need" when everything you get exposed to is "this weeks junk is blazingly amazing"

The short list of why I'm even worried about the computer would be:

A/C
Cruise Control
Gauges
ABS (my 88 s10 stopped like poo, this one stops good.)

At one point yesterday I was ready to piggyback an A9L to run the engine... or carb it. I have to say, the carb is looking way sexy at this point. Way easy, but where's the fun in easy. I'll spend about 20 more hours doing dumbass research because it's more fun. I've been rummaging around in the garage looking for water pumps, brackets, and timing cover from the Explorer engine I bought for a truck - I think this will fit easier than a 350 and may not need radiator relocation or electric fans.

I did find out yesterday that the core support will come out with not too much effort, that should make everything a lot easier. The suck part is having to learn about every Chevy change since the LT1 and getting sensor ability information... There's more information and changes out there than I had guessed.

I'm still bench building at this point, but I would like a small block that doesn't require me to hack the a/c box, beat the firewall with a hammer, or run the steering shaft through the headers. What has enlightened me the most - holy crap, the ubiquitous everything fits everything else Chevy engine is *history*. There are lots of interesting ways to build an LS... just getting all the right parts to put it together is a freaking nightmare. Long live Michelle Motors. Yikes.

ECM is supposed to service Vortec 4.3,5.7,7.4... just needs a flash. 16250279

I should just be able to match the firing order to the ford (er, make the same as LS1) on injectors and plug wires, or maybe the tune can handle it. Found a good page for GM sensor information:

Note to self - lower shround on a 98 has pressable clip ends at bottom of core and just yanking on it will break them. Doh.

Jeez, oil cooler, trans cooler all built into one core radiator... amazing little turd.

beer break - lordy, dripping already. Leather couches gain "character" this way. Yuck.
70mm MAF should be okay for a "5.3" (okay, it's 5.4 if you round up - 5359)

This poor couch may get turned into garage furniture... ;) Meanwhile, this GM thingy continues to deliver. There's two different crank and cam setups for Gen3/Gen4 SBC's.

58x reluctor wheel and 4x Cam Position sensor are 5v signals (gen iv) - The 24x reluctor wheel and 1x CMP are 12v (gen iii).

So much for "interchange" - I'm also thinking the S10 ECM may not fly with the Ford, I may need an LS type computer to get the correct firing order. Off to find out if the Explorer CMP is 5v, and if it's possible to mod it to a 4x signal - I'll probably have to modify the 58x wheel to fit the Explorer balancer.

Another reason why I think I'll go with the later 58x reluctor - see the way the older ones are built in layers? Yikes.

And it looks like the E67 cpu.. err... ECM is the way to go. Gawd, it's a 32 bit RISC.. more tech than we used to put man on the moon! Hell, my first "real" Windows in color capable computer was 16 bit.

Thinking about that... long run thinking, it can do displacement on demand, and the OD in a Z gearset T5 is a .63. I'll laugh like hell if I can get 30mpg out of this thing.

/edit - well, the GenIV doesn't handle anything but drive by wire and uses the BCM for that, and no IAC provision. Means no ac idle stepper and no cruise. Booo. This is a cable setup, so... back to the LS1 computer and 24x reluctor. Good news is, this makes the cam sensor easier, 1x instead of 4x. That means the early v8 Explorer ( 96-98 "sycnhronizer" (CPS) may well work. I think I can drop it in with number 5 at TDC (that's 1 in Chevy) and use the Ford tool. It also means I can find a more common 24x reluctor / sensor. I'm assuming this means it will all be cheaper since there is a bazillion more in the junkyard.

I think I'll pick one up and look at doing it like Randall did depending on it's size. Maybe it will work if I get it phased right to the Ford pickup built in to the timing cover.

thanks for a preview of the nightmare that will start with my Spider...

LS1 / truck computer ... I want the accessories (A/C) and cruise control to work. It's not that hard to repin and then it will need a couple extra wires added to the harness. Just time involved really.

50.00 computer, no assembly required. You can get them burned without VATS, Rear 02, EGR, Speed limiters removed, correct tire size, etc. for 75.00 usually, or you can go 500.00 for a tuner if that's your thing. I'm on the fence about the tuner... but the 75.00 sounds like the way to start.

[milner351]

Wow - I have so much to learn - reading this stuff is humbling.

I'd usually pick $75 over $500 any day too! ;-)

[Beagle]

Roger that - everyting I thought I knew applies to old Ford stuff. The last EFI GM I had (only one) was 23 years ago, and things have changed a bit in the General's camp. Just the changes in the LS world are kinda a lot to absorb.

[milner351]

Great that you're diving in - and all on a junkyard DIY budget - this is kewl stuff.
