Stand alone 4l80e

[05chevy]

Has anyone here do a stand alone for a 4l80e? If so what all does it involve? Do i still need the factory harness and tcm or will it do away with it? Im putting a carburated 5.3l in a 68 c10 and want the 4l80e for OD. The 5.3l will be operating off of a MSD box so I wont have a ecm to communicate with the tcm. Any in put or links would be appreciated.

You can use a Transgo full manual shift kit, but it won't shift automaticaly. Or get a complete stand alone computer with harness. There are a few companies making these. When I did the Grand National 4L85E swap we used an H&B and it was sweet.

Ok i def do not want a full manual shift kit. I will have to look into the H&B. Thanks Mike

OPTISHIFT has one that is pretty cheap, and can be set up without a computer for basic adjustments. Or you can go the JAKES route where you shift it yourself with a rotary knob.

Dunno what you are using for VSS and TPS, if at all, but if you have them, you could easily run a stock 0411 pcm as a standalone trans controller.

Better yet, just run the 0411 PCM to run the engine AND trans and have modern technology instead of putting dinosaur technology onto a ferrari. For the cost of the ignition controller, intake, and carb, you could just leave it as a GM fuel injection with an 0411 PCM and run it all for lessm oney with BETTER driveability than a carb could ever give you.

I'll second that.I talked my friend w/ a 64 malibu to do that.I think he's gonna let me get him an ls motor.

RPM transmissions in Anderson, IN. They hold numerous records with their 4l80 builds in nbs camaros as well as vettes. I am going to have them build me one for the Malibu when time comes.

The reason im going with a carb is I plan to run e86 and boost the snot out of this motor. 100+lb e85 injectors are $2000+. A e85 carb to support a 1000hp is $850. I thought about leaving it the way it is from the factory but later down the road I think it will cost me more.

How could I make the 0411 pcm work? Or function as a stand alone unit?

factory ECM supports boost, and E85.

And it will start in the cold...and it wont run like crap when its hot out...and you can have it automatically control e-fans...and you can diagnose problems easily...and it will get better fuel economy...and you can tune it with EFILive...and you can datalog the engines parameters for tuning rather than "guess and check and wheres my screwdriver" for tuning the carb.

And its so cheap and easy to make the factory ECM work as standalone. The truck/SUV harnesses are pretty much already setup for standalone. Just tie all the orange wires in the harness to battery +, tie all the pink wires to ignition hot, and the black/white-stripe wires to ground and away you go!

Especially if you are planning on running forced induction! Personally in my own opinion, I think youre nuts for messing around with a carb. Embrace modern technology....there is really is zero advantage to swapping to a carb on an LSx...

The stock LS1-b ECM is incredibly powerful (many tuners say it is one of the best and easiest-to-work-with ECM's of all time as far as aftermarket performance) and can be tuned to no end! GM's Delphi gas ECM's are a hot rodders delight, they really are. They even blow away most standalone EFI setups IMO.

I am running a 3bar tune on my 0411 swap.

And wtf 100# injectors are 2k??

TCI/FAST gm tranny harness is pretty sweet..

exactly,holley 120lb injectors are $450 and support 1700hp.How do I know,those are what we're putting in a CFE LSx headed small block running alot of nitrous.:woott:

From what I have found E85 injectors are a little more expensive then gas injectors. Maybe im looking in the wrong places.

Most of your aftermarket injectors are capable of using E85 or straight methanol from my understanding. To be able to run E10 they have to have vition selas in them, so that is all that is really needed to run E85 or 100% methanol from my understanding. And why do you need 100# injectors? Are you shooting for a world record breaking LS engine? I know I helped somebody with a 6.0L supercharged with 85 lb hr injectors, and that thing was a nightmare to try and get to run right. he ended up getting a blackbear tune for it after a local LS tuner couldn't get it to idle right. He sure wishes he would have used 60's on it afterwards.

 

[lts1ow]

You will want a larger injector for the same power level as a gasser would get. So the 100# guys could be warranted, I am shooting for 700rwhp and I am running 80# ones.

Could always run a set of 80#s and crank rail pressure to see how far you can push em. Better hope you have a nice external fuel pump or like triple -255s in tank, coupled with prob a -10an feed.

Friend runs the same ones and he has no issues with idling, all depends on how much time your tuner wants to put into your car. Just a WOT race tune will suck on the street, but its quick and easy to do.

 

[05chevy]

From what I have found is i would need 100+ injectors on e85 to make 800+ hp. I picked up a 5.3 for $250 so im going to push it to its limits on e85 and boost. Kind of like the hotrod mag motor they did.
