carb and 4l60 with stock ecu

carb and 4l60 with stock ecu can someone correct me if i am wrong. stock ecu needs to see vss, rpm from crank, tps from pedal, and map for load correct? if using a msd 6010 and carb setup, can you tap into the crank, cam, and map sensor to get the signals needed? then get power to ecu. will this work?
disguard the injectors, coils, iac, maf, and o2 sensors and only use what is needed to control trans.
has anybody tried to see if this will work? i think i read about somebody doing something similar with a sbc 350 vortec and 4l60e. they remove all the fi stuff and went carbed. they added a tps sensor on carb, swapped distributors to hei for rpm signal and it worked. this seems like the same concept. please correct me if i am wrong.

By the time you get everything wired up and possibly working, it would most likely have been cheaper and certainly easier to just get a tranny controller. LS1 pcms sometimes don't like to share signals with any other piece of electronics. Expect problems getting things to work correctly.

I would imagine it is possible. Can't say I have ever heard of anyone doing it.
Why not have the ECU control the spark as well? Skip the 6010 box altogether. That would save you from having to splice two sets of wires to each sensor. I *think* that has been done before.

if you use the ecu for spark, then you will need all the other sensors. an aftermarket controller is like $600 and up. they are doing pretty much the same thing i am suggesting. the only difference i see is they come with there own sensors.

Other than knock sensors I'm not sure what other sensors would needed for spark. O2 sensors shouldn't be needed for the ignition, maybe temp sensors would feed into it and I believe the spark does get an input from the gas level to know when the tank has been refilled and to remove the knock sensor retard.
I'm not familiar with HP Tuners but I would be willing to bet you could custom tune everything in the stock computer to make the ignition work with the same sensors as an MSD box. If you are going to keep the stock computer and wiring then why drop the extra few bills on the 6010?

You won't find the answers you seek in this subforum. Nobody here has done it and many have never messed with the stock computer in an form (myself included). I would try the tuner sub-forums. I am sure they will give you grief about trying to run a carb though. I think the trans-controller is the way to go.

if i remember correctly big chief is correct, they call the 700r4 a 4l60, could be wrong though
and the original question, im sure its possible, but youll have better luck with trans or pcm sections good luck with it

i am debating on buying another carb setup and try this in my 87 notch. i already have it fuel injected with the 4l60e but everything is stock. i have ls6 heads and cam i want to add until i get my other motor finished. if it doesn't work, i can use the trans in my avey and build my th350.
