DBW engine with NON DBW Harness..Possible?
DBW engine with NON DBW Harness..Possible? I am currently looking at buying a 2006 L33 5.3L with the factory alum block, higher lift cam, and ls6 heads for $900 with 100K. I am wondering if I can go buy a used harness and pcm from an 01, a non dbw throttle body, and hook it all up and it will run fine. Also what cams does this engine take? Can it use an 02-04 Z06?
I think you would need the PCM for a 2003+ engine. They changed a little
http://www.lt1swap.com/cable_conversion.htm Thats how you would go the other way around, and so you would have to have a pcm that had those connections.

The newer engine will have the 58x wheel so the PCM won't work with any engine designed for 24x (pre 2003 I believe). You could change the reluctor wheel to 24x but that requires removing the crank... I agree with Palomba and suggest buying the "right" (58x wheel) PCM and harness for the engine then eliminate DBW in the programming if you don't want it.
-The early harness could be converted if you wanted to go through all the pain
-The early PCM will not work due to the 58x wheel as mentioned
-You can convert the engine to non DBW but why?? I did it to mine, and it can be done.
-If you get the proper ECM do not convert the engine or harness to cable TB, the new ECMs do not have drivers in them for the IAC

Thanks for the eyes, Jones'n. The collective mind is smarter than the single.

Verdad Gallardo The L33 was never made until 05'. It was an option on extended cab 4x4 05'-07' Classic 1500s. This is not the trailblazer/envoy/ssr motor you are thinking of which have 5.3L heads. This engine also has HD rods, flat top pistons, and 9.9:1 compression over the standard 9.49:1 from an LM7. Even comes with active fuel management...whatever that is. Now I am really confused if its 24x or 58x...The engine is kinda far away so I hate to drive that far and find out. Can the sensor be looked at without removing any parts so they junkyard could look for me?

I don't know how many times I have to say it is a 24x engine.
The 58x wasn't in any trucks until '07. So if it is from a vehicle that was made prior to '07, it is 24x.
As for the DOD, that part wouldn't work with an older computer. You would need to keep the electronic throttle and run the right computer for the 24x 5.3L DOD engines (aka E40)

Alright, I have a L33 with 55k that I picked up from a 05 Silverado. I am running a 04 truck harness and a 04 GTO PCM. I converted the harness and the engine to DBC, because I was having crazy issues with DBW, 04 Truck PCM and T56.
Oh, and I'm also running a stock Z06 cam and springs, F-body accessories and LS1 intake.

OK, since I messed up on the L33, I'll TRY to get this part right. If you,re going to use the early PCM and harness and you want to eliminate the DOD. I/We just finished doing this with a lot of help and info from other members on here. Do a search for a thread titled *5.3 LH6 Progress and Problems* by **Geezer's Garage ** or one titled *info to eliminate DOD * by **rojs234 ** You can find them easily by clicking on advanced search and typing them in the boxes. There is also a thread right now in the GEN lV internal engine forum titled *AFM/DOD Delete by **sommatt** that has some info. Even though these are about LH6 engines it would also apply to your L33.

Ok, there still seems to be some confusion here. The L33 does not have DOD and the L33 is 24x. You will be just fine if you decided to convert the harness to DBC and use a DBC PCM. Again, I have a L33, that has been converted to DBC and I am using an 04 GTO PCM and a 04 Silverado wiring Harness with blue and green connectors that was originally DBW.
[edit] 5300
[edit] Generation III
The Vortec 5300, or LM7/LM4/L59/L33, is a V8 truck engine. It is a stroked (by 9 mm) version of the Vortec 4800 and replaced the 5700 L31. L59 denoted a flexible fuel version, while the LM7 was the standard version of the engine.
Power output is 285-295 hp (213-220 kW) and torque is 325 lb·ft (441 N·m) to 335 lb·ft (454 N·m). Displacement is 5.3 L (5,328 cc (325.1 cu in)) from 96.01 mm bore and 92.00 mm stroke. Vortec 5300s are built in St. Catharines, Ontario, Romulus, Michigan, and Silao, Mexico.
[edit] LM7
The LM7 Vortec 5300 was introduced in 1999, and can be considered the "garden variety" version of the Generation III 5.3 liter V8's.
LM7 applications:
2002-2005 Cadillac Escalade 2WD
2002-2006 Chevrolet Avalanche
2003-2007 Chevrolet Express/GMC Savana
1999-2007 Chevrolet Silverado 1500
1999-2007 GMC Sierra 1500
1999-2006 Chevrolet Suburban/GMC Yukon XL
1999-2006 Chevrolet Tahoe/GMC Yukon
[edit] LM4
The LM4 was an aluminum block version of the LM7, and had a short production life. It should not be confused with the L33.
LM4 applications:
2003-04 Chevrolet TrailBlazer EXT
2004 GMC Envoy XL
2004 Chevrolet SSR
2004 Buick Rainier
L33 Vin code "B"
The L33 was an aluminum block version of the LM7, and was referred to as the Vortec 5300 HO in marketing materials. Power increased by 15 hp (11 kW), to 310 hp (230 kW), over the LM7, and torque was unchanged. It was only available on extended cab 4WD pickup trucks. Only 25% of trucks made in 2005 had the L33 engine.
L33 applications:
2005-2007 Chevrolet Silverado 1500 4WD
2005-2007 GMC Sierra 1500 4WD
