84 K20 "Ethel" Not an Sbc/NV4500/241C

Semi restoration of a 1984 K20 pickup. 5.3 LS, nv4500, np241c.
Lemme just put it this way, it fit when she was a slow crawler... now it's not even close to the meaning of that.. I have no other wheels right now so we'll see how the year develops.
 
Why bother with the K5?
There is no shortage of Fords in the junkyards to salvage beams off of.

lol I'd never beam Ethel.. she is a daily, I don't like buying tires or caster change.. staying solid axles. The k5 is what it is for now. Which needs to be finished.
 
Finally read through this whole thread. I definitely dig this truck. And YES to the LS Swap! (although the diesel was still pretty cool and kinda unique)

I thought that all the Gen IV 5.3 motors where aluminum?

EDIT: Googled it:
The Generation IV 5.3L engines share all the improvements and refinements found in other Generation IV engines. 8 versions of the Gen IV 5.3L engine were produced: 3 iron blocks (LY5, LMG, and LMF) and 5 aluminum blocks (LH6, LH8, LH9, LC9, and LS4). All versions featured Active Fuel Management except for the LH8, LH9 and LMF.

Disregard my super sketchy temp wiring setup, I needed to verify the engine actually ran with no issues.

Go figure the ecm is out of a 6.2 so it's pig rich with the extra fuel pressure also.. 48lb/hr lol

After missing a couple of things I didn't know I needed, push lock fuel hoses a lower pressure regulator etc(get into that later). I got power to the ecu and copied the stock file and saved it. I unlocked the ecu with hp tuners and applied the vats patches to disable vats, and every smog related device and trouble code. Then wrote the os back to the ecm. Powered it up and checked the scanner to
See if anything was reading properly, I had map, iat, but no throttle, I had purchased a non delphi plug for the throttle pedal which I realize was not wise. I'll be getting an oem connection to resolve this.. it actually made me recheck my app sensor wiring because it was intermittent and not working, once I checked the connections and got it actually to connect the throttle worked perfect.
I wired up the fuel pump and starter, bolted up the flywheel with the longer bolts.
And started it!! Kinda scared me because it roared to life and I was sitting next to the exhaust with my laptop!
But damn it's smooooth!! Snappy too! So now it's full mission get this fkr in asap!
I'll get the quick 20sec video on you tube!
 
An '09 Yukon Denali 6.2 should only have VVT but NO the AFM. Maybe these tables are hidden and just disabled in the ECM for the 6.2?

The Afm stuff is just turned off, I actually haven't wired that up yet so that is on the list. It's easy to enable it then copy tables from a truck with those values.
 
Don't forget to turn off torque management :waytogo:

Also since you're running a manual transmission there may be some segment swapping that needs to be done with a manual Camaro/Vette tables in order to get the right on/off-throttle response. (As in the engine will slowly close the throttle when you let off and not just snap back to idle like it needs to with a stick)
 
I poked around in the file and switched it to manual, by I still as you said need to kill the TM, there is the DFCO and I think I can pin the clutch pedal switch into the ecm so it knows its depressed, but as far as I can tell there is nothing missing from this tune comparing it to a corvette of the same E38 type ecm. I brought my laptop to work so I can play with this. I'll grab some screenshots.
I guess the segment swapping was with the other older ecus and in order to do that with this gen iv I might have to send the files to hptuners to modify.

Ya the Gen IV stuff is a bit different since they separated the transmission controller. But don't consider me an expert or anything as I'm just passing on advice from many other swaps I've read into.
