I've read multiple threads but they all end up the same I've had the msd 6014 before and I loved it but I sold it to fund MY FUEL INJECTED VEHICLE the reason why I wanna run the gm pcm is because I already have a full harness and pcm and plan to run a 4l80e that's the other reason for transmission control . The thing I've noticed is most forget about a tps needing to be attached to the throttle and I dont want efi because I already have an efi vehicle that's turbo so please dont suggest that, can anyone who's actually done this please chime in I just love the idea of an analog fuel management type deal any help on this topic will be greatly appreciated

 

not really the way id go, but it seems like you could just plug in all the other sensors and then leave the injector wires unhooked. youre still going to need to tune the timing table and transmission but ¯\_(ツ)_/¯
heres a tps kit

Anything is possible, but I'd say the same thing as TS that the timing and trans will still need to be adjusted. Also, who will be tuning it for you? What are the benefits to using a fuel injected GM ECU to control everything but the fueling? It seems to me like you'd end up bouncing between tuning the carb and EFI to find the sweet spot.

 

ah your so right this post was meant for me specifically because I dont have a gazillion dollars I've read people have done it using a tps adapter and that seems to be all that's needed but your right I guess I didnt think too much into it

 

You don't need a gazillion dollars to run an OEM injection setup. Every LS engine comes with it...

 

Yea not wanting to run it as a fuel injected I'm working on getting an msd6014 anyways besides people complain bout carbs, seems that it's a lazy thing lol how dare a carb make you drive it around the block whip out a screwdriver and adjust accordingly 🤣

 

Agreed!

 

Once tuned, you never even have to do that with injection. It is LESS hassle to deal with than carburetion. The mix is ALWAYS perfect.

 

"never have to deal with it" seriously sounds like something a lazy person would say ,I dont think it's good to put that in other people's head instead of saying efi is the way to go why not include the carburetor to the list of possible fuel delivery options . take the average person that's optimistic and ask them would you rather learn how to tune a carb or tune a fuel map with a bunch of tables and numbers I've dealt with both already and I'm ok with computers even with that I'd honestly rather just have a carb and I even have the terminator x even with that I regret getting rid of my carb for this system

 

Each their own but I think you are answering your own questions while looking for validation from others who don't / can't / won't the same picture.
I'm a fuel injection guy through and through - however I understand there is a place for carbs and I still do stuff with them. Carbs aren't simpler than fuel injection we've just had them for the last 150+ years and they are better understood by a larger section of the population.

What I don't understand is how / why you feel using the factory equipment that came with the engine is too expensive. If you feel it's too complicated, won't look right on your setup, can't tune it yourself and don't have anyone you can trust or don't feel comfortable with wiring, etc. I get it - this happens for people so they default to what they know. I read your post within an hour of its creation and I simply don't understand the logic of trying to run a computer controlled transmission with the factory ECM and control the fueling with a carburetor. I'm not saying it can't be done (I'm rarely that guy) but within the OEM ECM much of the shift points and shift firmness depend on engine load, throttle position, vehicle speed and RPM. Without having some sort of feedback from the engine I simply don't see it working or if it does, not very well.

I'm not trying to be negative but why not cut the baloney and simply purchase an aftermarket transmission controller for your application and call it done. They are designed to be stand alone and don't rely on so many parameters for shifting and shift quality. I realize this may be a few hundred dollars or more including harness but a couple wires and a few plugs later and the job is DONE and you're driving instead of troubleshooting your creation. That is always a happy day for me.

In the end this is your project so build however you feel will make you happy but don't be surprised when people are offering less than enthusiastic support for what sounds like a Rube Goldberg idea.

 

Barring being a cheap ***.....the only place a carb has on an LS is at the racetrack.

 

hmmm cheap *** you say hmmm let's see compares to the efi system let's see I got a busted ls6 intake I repaired it plus injectors
$270.00
holley terminator x
$1080.00
Total-$1350.00
carb setup
Holley intake 300-130 at summit with studs $338.98
Msd6014-$412.25
mallory pressure regulator $150.00
demon carb- $335.00
Air cleaner 50.00
total-$1285.25
So whats your point exactly
all brand new carb related items came out cheaper
you dont know what I need my build to do carbs have been around longer than efi has think it's easier to buy an old carb guy a 6 pack and pack of cigarettes to tune a carb over paying big money for computer tuning and dyno time, look analog is better for me cause I can learn it and trust me when I say this that thousands of others dont wanna sit there and learn fuel tables when you can just turn a screw driver and get on the road simplicity by the way I have both a carb and the terminator x ironically the cars been on the road longer with a carb than any efi I had on my car like I said it works for me and it's an option for many others also the terminator x is for sale because again I DONT NEED EFI

 

oh sorry I missed your responsresponse no I was just looking for a cheap way to go about using maybe a 4l80e and no I'm not looking for validation from anyone I'm posting these answers and my feelings towards a carb vs fi so that incase someone that doesnt know which way to go they can have more opinions that would favor a carb because every post you see everyone almost everyone trashes the carburetor because they prefer efi but dont turn away others from another possible solution that could very well perform better for them then having a mess of wires just my thought some ppl want simplicity and a carb does just that in most cases these are fun cars that need maintenance like anything if you want something you feel needs to be factory reliable then go to your nearest dealership and get you a nice Prius

 

I appreciate you proving my point. Less than $100 difference in your example. Drivability and fuel economy alone would pay you back the cost of a tuner. And you tune it once for the mods and you're done, no adjusting for different weather conditions. Time is money too, so actually between fuel mileage and your time it ends up being cheaper in the long run. End of story.

 

end of story? Tell me did they tune you without your maf sensor cause I'm curious
and prove your point? I didnt ,had a carb setup been 600 total than id proudly take the "cheap ***" jab with pride and again if you dont wanna adjust things on your car then dont have a project car like I said I dont mind adjusting a carb i really dont and that's why you dont put all your eggs in one basket if your ls swap isnt your only car than the adjustments shouldn't be a problem that's why I have a little rice rocket daily it's a FUEL INJECTED 4 cylinder and lol did you really bring up gas milage? besides its allways hot in TX so the "constant" need of adjustment for temperature isnt a factor here lmao as a matter of fact a carb with no choke around here wouldn't be a problem like I said I know the majority of people prefer efi trust me I've tried both gm computer and the holley because I was going turbo but I ran out of budget and running a near stock NA 5.3 with a really nice efi system like this didnt make sense so I threw the carb back on it and am selling the terminator x because I have no need for it seriously efi is preferred by almost anyone but dont discourage others, i feel kinda of bad for the other carb guys people bully them into getting rid of there carb setups and all that happens is that their cars are just parked outside because they gotta learn how to adjust fuel tables seriously anyone wanting to run a carb and your reading this DO IT because your the one that's gonna be working on your car not the guys on here that keep trying to shove efi down everyone's throat 👌

 

I guess its hard to teach an old dog new tricks. I'm no spring chicken and learned to tune it myself. You don't have to have a PhD to use it or learn. The average person nowadays is willing to either spend the time to learn, or hire a tuner, many of which will do remote tuning and you don't even have to take it anywhere. This is all besides the fact that new computer self-learn the car or setup. If anyone is trying to bully it's you trying to justify how terrible EFI is. If you don't want EFI thats cool, but there are literally thousands of people all the time accomplishing what you say is terrible and enjoying their newfound power, reliability, and gas mileage.

 

Danny, if you are trying to convince people on this site that running a carb is better, you are on the wrong forum. As someone said earlier, carbs on an LS motor are for the racetrack. Paying for a reputable tuner and/or learning to tune yourself is money ahead.

Fuel mileage is one of the huge benefits to running an LS motor, so if you are discounting that you are missing out on one of the biggest advantages to these motors. Just because cars from the 60s, 70s, and 80's only got 10-12 mpg doesn't mean that you should tune your LS motor to get that type of mileage. I'd rather use my fuel savings to save up and buy a cam, go fast parts or deluxe screwdriver sets than running it out the tail pipe.

 

Your right about that everyone here obviously cant have anything that isnt efi so your right no point in wasting my effort here lol not really an old dog as a matter of fact I'm just a young cat trying to get his car to move to the point where it doesnt matter what I'm using for a fuel delivery system well thanks for everyone's time and opinions good day

 

Best of luck, hope you get the setup that works well for you. Take care.

 

Massive snarkism, this man has....
