Mike

The speedo is an Autometer sport comp. electric speedo ~$200

Good question about the SA-001.....I mounted it there cause I was originally going to mount the ECM on the inner fender.....I guess it never dawned on me to move it inside too.

I wasn't planning on making a shield for it, since it already has covers over the fuses and relays.

Kept plugging away at the wiring tonight.

I drilled and tapped the frame for ground wires. Since my battery is in the bed, and the entire frame was painted with POR15, I figure this is the best way to ensure I get a good ground.

I need to get a few connectors tomorrow to hook up the ground wires.

So tomorrow I hope to get it running. I have a few things to do:
Wire up the ALDL to I can flash the ECM.
Get some bolts for the headers to fully install them
Wire up a few more wires.
Hook up the power steering lines
Go over everything one last time to make sure it "should" all work.

So hopefully if all goes well I'll post a video of Bruiser running.

bet your ready to hear him run man! its been a long journey!

[Ackattack]

No running today. I ran out of time, but I'm very very close.

I realized I need some newer gas. The gas that is in the tank is ~year old (when I did the plumbing for the tank) and then I need a 2 guage lug for the battery cable.

Then I have just a few more wires to hook up. The fuel pump and sending unit, the MAF switched wire, and some more ground wires.

If we weren't going out tonight it would be running tonight......

Keep it UP! Hey, what engine mount adapter plates did you use to mount your 5.3? Did you use the original a/c compressor? Relocate it? thanks,

Mike

I made my own adapter plates out of 1/4" plate.

The A/C compressor is an F-body compressor using corvette accessory brackets.

How did you mount your PCM? I didn't see any bracket?

It looks like he modified the original mounting sheetmetal bracket to mount it to the tranny cover.

I drilled out the ECM bolt holes and then put some 1/4" all thread threw the holes, and then tightened the ECM cover back down with some nuts. Then I adjusted the all thread so it was long enough to go through the sheet metal mount.

Shouldn't these PCMs have a little isolation from vibration?

Don't know. I could pretty easily add some rubber washers if it's a problem or concern.

I have to remove the ECM and stuff at some point to paint my mount.

Sweet good job! I hope I am only a few weeks away from this on my Tahoe but only time will tell.

I have a few issues to work out.
The gas pedal isn't working the throttle body.....I got a DTC for that
The tachometer isn't working and I got a DTC for that.
1 of the electric fans isn't working.
I got an exhaust leak or two.

Earlier today I was using a battery charger to test some things out, but HPtuner wouldn't connect to the ECM. I checked all of the connection to it, and it checked out. Then it dawned on me....the battery charger was only putting out ~10V by the time it got to the ECM.....so I hooked up the battery and that was good. Then it would turn over, but not start....it sure sounded like it wanted to, but wouldn't. Then I realized the vacuum port for the brake booster on the intake manifold was open. Plugged that and it pretty much started right up!

When I got HPtuner loaded, it told me the ECM was an 05, and I thought it was an 04. I'm using an 04 wiring harness. That could be the issue, but I'm guessing not.

[lyrikz]

Normally one fan ties in with the AC system. It doesnt turn on unless it gets a signal the AC is on. Just a thought.

[Hart_Rod]

Sweet! Who did you get your software from and what all can you do with it?

[menace121978]

right on man. now that you heard him run it wont be long now! congrats buddy!! as for the pedal... Bob(glock) had a similiar problem with his. he had a pedal out of a '04 and he needed the new style pedal out of an 05-06 to jive with the ecm. check his build thread here http://67-72chevytrucks.com/vboard/s...350986&page=34 between page 30-34. just an idea and thought man good luck.

sounds like you need a couple big heaters out there. (unless your garage looks like mine) 36* is a bit chilly

[Thealien]

I am watching this for your troubleshooting solutions. My engine should be going in within the next couple of weeks? Sounded great, you must be thrilled. I hope the pedal is a simple fix for you!

[Ackattack]

I got the software from HPtuner (google them). You can pretty much retune everything, fuel tables, spark tables, transmission shifting, fan on/off, speed limiter, rev limiter, error codes......about anything the ecm controls.

There is even options for 2 bar/3 bar setups for high boost turbo/supercharger applications.

I need to check the wiring on the TAC module. Luckily our crewcab is an '05, so if all else fails, I can yank out the gas pedal to see if that's the problem.

I'll have to check on the fans. In HPtuner there is a high setting and a low setting. Only the high setting turns on the one fan. I figured the low setting would turn on the other one.

AWESOME! That thing sounds good coming out of those sick headers! Let us know what you find out about the little bugs. Keep it up! you should be driving that puppy in no time.

You're probably right, I could drive it in no time.......but I live in Washington where it rains all winter, and I live down a mile long pot holed drive way, so it may be spring when it drys out a little before I actually drive it. We'll see though....maybe it will dry out for a few days.

[lippsgarage]

Awesome man, awesome. Although, I think you just convinced me to do my 383 carb swap with a shaker hood for my '79 Gimmie nuts and bolts, wiring, other than stereos, I'm Glad it's all coming together for you though. How's the little guy doing? Happy Holidays, Merry Christmas, and everything else.

[joejbal]

Is the throttle body, tac module and pedal out of the same truck? If so, the problem is usally that the tac module doesnt have power in crank AND run.

[Ackattack]

Got the gas pedal fixed....easy fix.

Basically the TAC module wasn't getting an ignition power supply. I had the wires all hooked up correctly, this particular wire going to the "Empty IGN" wire on the SA-001 fuse block. Well that wire does not come with a fuse installed.

So after a few minutes of testing with a test light I narrowed it down to the problem, installed a fuse, and fired it up.....and then reved it up!

On to the next problem!

[Thealien]

Sweeet

[Ackattack]

Last night I was able to remove the steering column, re-weld the tab for the nuetral safety switch, and then re-install it.

I also noticed (after trying out the thottle) that the water pump is leaking at the block. I know that the water pump and the rest of the accessories were on a different block before I got it, and I never changed out the gaskets when I got it. So it really isn't a surprise.

I ordered a rag joint rebuild kit, so hopefully I'll get the tranny shifter set up installed, as well as the rest of the steeriing column shaft this week.
