I'm ****ed

Or does the mechanic think bent rods?

Bent rods, locked up, its not usable.

Maybe I missed it but what made you stop? Did you get stuck or did the electronics freeze up everything?

post lots of pictures of your swap on the Build section... it's amazing (to me) how often I get someone contacting me about something I did with one of my rigs - I know it helps them, and as a lot of what I use comes from others posting up.... this will be cool

 

[zackcrum]

This is gonna be awesome! Make a build thread!

Interested to see how this happens

I hit the water, water splashed on the windshield then it died. Looks like it was water and not electronics.

It was easy to pull out, a 4 wheeler almost got me out, i got pulled 3/4 of the way out by a F350 while my rig was in park. Then i finally figured out how to force it into neutral, i had to tell my friend over the phone how to do it because while this all was happening I cut my toe wide open, so i was sitting in the hospital getting stitches while hoping they didn't break my rig. It was a crazy day.

Luckily i didn't break any of my front suspension from getting dragged out.

Exciting to hear about the swap. Motor must have run after it ingested water to be locked up. We have pulled plugs, cranked the motor a few times to expel the water, put it back together and driven away after a serious dunking.

Jeez, that's quite a day


...What did the city girl think of these shenanigans?

Probably the last time she will ever leave the asphalt lol

Really? I'll have to ask my mechanic about that, did it run normally? Did you bend and rods?

As soon as the trucks went under the motor was shut off. That keeps the fan blades from shedding and the water getting into the cylinders. I have not done it myself but have helped a couple of people that wound up in that situation. One of the occasions was a trip done the Mojave Trail. There is a water crossing toward the end and a guy that was with us in a Toyata truck stalled out in the crossing. He tried to start the truck again and we yelled at him to stop. Fortunately he did. We drug him out, pulled his air filter to dry it out, checked the manifold and remove all of his plugs. We then did short cranks until all of the water was ejected from the cylinders. Put it back together, truck started right up and he completed the trail and drove his truck home. That has happened a couple of times. Key is not trying to start the truck until the water is removed. It doesn't compress like fuel vapor. That is where you get the bent rods, etc.

that is not deep and this was in the middle of winter
there was an 8 inch lift under her.

Maybe they tried to start it while I wasn't there and didn't tell me? Other than that water could have just flowed in through the intake? But wouldn't the throttle be closed? But again i was sunk pretty deep so I don't doubt that I sucked up water.

Highly possible. Even while you were there, did they remove the plugs before trying it?

Throttle isn't air tight, it just restricts otherwise the engine wouldn't idle.

I believe i found the problem, lack of speed :huh:

I made it 3/4 of the way, i was probably going 20-30mph. It was a HUGE hole, i'm surprised i got that far.

Yes they removed everything, he said he tried to "turn it" not sure what he meant by that. No gasoline was involved in the process.

This is slower speed and deeper hole

I was there for that episode in Gorman. The floating Suzuki.

no - the I-5, you swap PCMs with PCM of NC; on the 5.3s, it's a different computer (much, much better computer) that allows reprogramming with HP Tuner software... meaning, you don't swap computers, just the software inside.

Huh? PCM of nc uses hp tuners to tune. Any PCM. They preprgram a pcm and use those as the exchange program or hook them up to the hp tuners and tune them using the same software suite for the same make.
The alpha doesn't have a magic computer that is much better it actually has less memory than the 07 PCM. Because it wasn't needed to have the more memory with the coming of the TCM in 08. All h3's after 08 have the same set up: PCM and TCM.


For the record BCM PCM and TCM are all different and the terms are not interchangeable.

Hp tuners can tune the TCM and PCM. Of any year. Magical alpha or not.

So which ones do i need to get for the swap?

so you're going to completely reprogram a 5 cylinder computer to run 8? how, exactly are you going to get the 07 computer to recognize the extra coils and the extra injectors? that'd be a cute magic trick... which comes back to why work so hard when GM did it for you. The hardest part will be to get the other computers to play nice with your new engine computer. But I do love the stick-up-your-ass-attitude... so carry on with that magic trick.

get the V8 wiring harness, PCM, BCM, and TCM.... again, were it me, I'd buy a wrecked Alpha, failing that I'd have 150tunes splice in the PCM into the stock 07 H3 harness.

years ago... damn, decades ago, a friend decided that he wanted EFI on his 85 Chevy truck, so he swapped in an 87 motor (efi motor) and set about wiring in the motor. In the end, he swapped every bit of wire from the 87 (and the dash cluster) onto the 85 - nothing was the same. 07 and 08 had some differences in the vehicles (e.g. air bag arrangement) and for that reason my guess is the wiring harness is substantially different than the 07. It is not plug and play, but it can be if you get someone to make the harness for you. The fab work is easy, but since absolutely everything is electric on the H3, getting everything to play together will be the major challenge.

Maybe they will chime in but I could have swore pcm of nc said in one of the other swap threads that they can program the i5 pcm/tcm to work with the 5.3
