No burnouts yet. the motor only has 260 miles on it right now, still have to break her in.
I'm getting idle are control codes for the rpm not being where the computer expects it to be. Could this be caused by deceleration since the vss isn't hooked up?

I can't remember what the Chevy's asking for as far as a signal, so yeah, but it depends on how you addressed the neutral safety start issue. You could always get a hold of one of the VSS converters Marlin sells and hook it up to find out. Maybe even a signal box to simulate it?
I had a similar issue when I did the 2wd A340-E to 4wd R-150 swap on mty '95 Runner where I simply fooled the trans computer part of the system into thinking O/D was off, letting me retain cruise and proper emissions. Have you seen if toojayzee, or some of the other hardcore section peers have any thoughts on it yet? https://forum.ih8mud.com/hardcore-corner/341445-project-effjjay-eighty-2uz-powered.html
Also, Nice Build!
x2 on the good build. All that wiring would make me go insane.
Keep up the good work.
Keep up the good work.
phishincruisin to gain some extra length of tailshaft to ensure the timing pully(redneck reluctor) stays on i machined the tailshaft locknut (specifically the locking shoulder) down. Also it will help if the inner bore of the gear is within .002"~.004" of the thread dia of the tailshaft. Also locktite never hurts
I drove it...5.3 just moved way up on my list of mods to add to my cruiser.
What what???
It towed like a champ, the trailer is obviously too small (the Subaru had no engine or seats) but the cruiser pulled it effortlessly. The people that say cruisers cant tow are crazy.

Thanks for the info mwdubs. I'm going to try and figure out how to get that to stay on.
After having the cruiser on the road for less then a week after the motor swap we drove down to Moab for a few days, and then continued the trip across the country and to VT. The truck ran great without any issues which was awesome. I think I averaged about 15-16 MPG with a bike on the roof and 6-700 lbs of junk in the back. I'm hoping once I get the VSS figured out my MPG with increase.
Today I installed a rear sway bar and a not-so-bent stock front bumper to clean things up until I have the time to build one. I also tested out the towing capabilities of the Vortec which proved to be great. We had to pick up an Impreza, minus the engine, seats and some interior parts. Including the trailer I estimate it weighed around 3200 lbs or so. The truck had no problem keeping 70-75 mph uphill in 4th gear, and the motor wasn't even working that hard.

Figured it was time for another update...
Just got back from a 1200 mile trip to Pennsylvania and back. That puts about 7k on the swap so far. I averaged about 15.5 mpg at 75mph which is about 3k rpm. I'm sure I would get better mileage if I had a 5 speed and lower rpms at highway speed. What are other guys getting for mileage with their swaps?
Before we left I installed a new headlight harness and my brothers IPFs for the trip. Those lights make the biggest difference at night and in fog. I just ordered myself a pair for my truck, since my brother is going to want his back soon.
I haven't had any issues with the swap, just a couple hose clamps that needed to be tightened a little bit. and the pesky CEL from not having a VSS yet.
What are thoughts on tapping the end of the transfer case idler shaft for a bolt to hold a reluctor ring gear on the the shaft for my VSS? the heep guys do something similar with a SYE kit.

The shop that is wrapping up my 5.7 swap just finished a 5.3 swap into an FJ40 and machined the tail housing/shaft for a VSS. They epoxied the sender into the housing. It looks real good.
If you want, I can ask them for some pics and a more detailed explanation. On mine, were using an in-line VSS since I'm running the stock 4 speed and mech speedo.
correct me if im wrong, but it doesnt sound like "we" are doing anything, it sounds more like a "they"
You stand corrected. I say what I mean, and I mean what I say. Thanks for putting me down in an internet forum, though! NICE!

I'd be curious to hear/see what they did. I want to mount mine on the end so that it can go in a little vss housing I made. My only issue with it is that the gear I was using for a reluctor fell off, and I'm not totally sure the best way to secure it.
What inline VSS are you using? I have the stock 4 speed on mine with mech speedo. I know I can have the computer flashed for a different pulse for the VSS, like a 4 pulse, but since this is my daily driver, I can't be down for the week it takes to send the computer out to be reflashed.
I'll see if I can get the part number for the VSS that's going in. Mine may be different from yours since I have the L31. I'll also see if Ron can set me up with some pics and better info on how he put that VSS in the tail housing.
The vss is defiantly going to throw off your mileage. That's part of what tells the computer to lean it out at certain speeds reducing fuel consumption at highway speeds. That 4 speed is also most likely a horrible match for what the ecm has mapped out as far as speed, fuel mixture, and rpms so if your going to keep running it for an extended period of time I would have someone reprogram it to match your rpms.
Honestly I would think if you had the vss and your ecm tuned for that transmission it would be much improved.
I get 17mpg on 35s and 8 inches of lift with a tbi/4l60e at 70-75 so I'm willing to bet with your setup you could do at least that and probably 19mpg with some type of overdrive trans.

I want to know where the Phish sticker is!

I know not having the vss will throw my mileage off, but since no one currently makes a vss setup for the splitcase, I haven't gotten around to it.
A lot of LSx swap guys don't end up using a VSS. My understanding was that the PCM used the VSS to know if the vehicle is moving to lean out the mixture at speed, and also for a decel fuel cut. So right now my engine is running a little rich. I plan to install a wideband and get EFI Live and start tuning myself. I'm not really one to bring my rigs to someone else to do work, because then if it breaks in the middle of nowhere you are SOL.
What is your engine RPM at 70-75?
How would you tune the PCM to the transmission since the PCM doesn't know what gear the transmission is in? Isn't tuning all load and RPM based?
