    early 4l80e to 6.0?

    and if it really comes to that I'd go with a stand alone controller before a TBI chip. lots of guys have to mail them back several times to get a good one.

    th then why dont guys running carbed 6000rpm motors have to do that? or the three Cummins swap guys I talked too? which run at much lower rpms.

    early 4l80e to 6.0?

    I mean if you get a complete motor with the stock harness and CPU by all means do it that way but that isn't the setup I had. I got a lq4 with everything but someone else had bought the CPU and harness. since it went in a old 4 speed truck first the kit from summit was perfect. had everything I...

    early 4l80e to 6.0?

    its actually not, already dealt with the issue I think eveyone else is doing it the over complicated way. here's what you need same as when you carb a TBI truck all you need is TPS VSS CTS and an rpm signal. then the trans will run and shift just fine. the engine is stand alone same as when you...

    early 4l80e to 6.0?

    idles crappy and dies when you stop but only sometimes, plus it makes zero power. I have no interest in throwing money at the TBI or swirl port heads lol. I have a set of recently done vortec heads from a friend an edlebrock intake and cam kit for this motor and it' going back in the 86 the 6.0...

    FiTech EFI for 350 TBI/Vortec

    did you ever get the TPS to work?. I was wondering if the the one from summit that got a on the linkage and uses the factory gm plug would work on a Fitech. if whatever come with the fitech didn't

    early 4l80e to 6.0?

    I never intended to do an ls swap to this truck at all but the TBI system started acting up and I figured if I was gonna get rid of the TBI anyways why carb a newer truck. so I want to build the 350 and put it in the 86. And with how simple the last one went I figured this would be a breeze. But...

    early 4l80e to 6.0?

    there we go never thought of asking the guys who have done a Cummins swap how they did it. makes sense though if it would just be TPS and the speed sensor. And and es that' my plan I don't want to remove any of the tbi wiring or electrical really I used the stock stuff for my fuel system. I'm...

    TBI 4l80e experts needed

    when you carb a tbi truck with the 4l80e your computer is no longer running the engine but your able to trick it into running the transmission still. my question is how is this done because want to run a standalone 6.0 in mine not a carburated motor but I want to wire whatever sensors needed up...

    early 4l80e to 6.0?

    need a guy who knows TBI trucks to chime in someone who has carbed one and knows besides the tps which other sensors I need hooked up can't be more then four or five things TBI computers were slow turds

    early 4l80e to 6.0?

    like I said PSI and other forums told me to get a newer trans and the harness and computer for all that and put it in. thats to much nonsense.

    early 4l80e to 6.0?

    I'm not trying to be rude guys. but it should be something simple I've checked every Chevy and ls forum no-one has an answer even if I went your route with a stock CPU. no-one knows how to make that work my trans no company I've found can make a harness the plugs into my 6.0 then into a CPU then...

    early 4l80e to 6.0?

    how would the factory cpu change anything? according to psi you can't make that modern CPU run my trans. I'd still have a running motor but be wondering what I need to wire up from whats already there to the stock 6.0 harness to work the cpu already running the trans. I'd be in the same boat but...

    early 4l80e to 6.0?

    it already ran and reliable with the fitech for 8 to 10k it is a great turn key system. literally plugged into the engine like a stock harness all it needed was power and ground. And and a safe place for the fuse block and CPU. I'm not changing the engine or harness at all I don't think any of...

    early 4l80e to 6.0?

    never heard of black bear I will give them a call psi is who told me they couldn't make a harness for my 6.0 and my early 4l80e. they could only do it for the late model. they recommend I change to a late model trans.
