Which company has a TBI kit that uses a little hand held programmer to tune it?
Edelbrock dosn't make a TBI system. All they make is multiport.
Holley TBI systems use either a laptop to set the fuel curves or knobs on the ECU for adjustment.
Neither uses a hand held programmer that i know of.
Here's the link to info on the Pro-Flow multiport FI that uses the handheld calibration unit.
I am running the edelbrock multi port kit #3500. I am very happy with the quality of the unit. The only bad thing i have seen is the price. $2079. It starts great, runs great and is very easy to adjust and make changes. The changes are instant. It is a little difficult to get the cables hooked up and working properly but this is a problem you would have with any kind of swap. Hope this helps and if you have any questions just ask and i will try and answer them. One other thing is the tech help from edelbrock. It is the best. Terry at edelbrock is very sharp with the proflow and has always been able to answer all of my questions and help me correct my mistakes with the programming of the kit.
I'm running the Holley 4brl TBI Commander 950 system, and I've been happy with it. You have to use a laptop to tune it, but it's a pretty user-friendly interface. Holley provides an extensive selection of base fuel/spark maps, so it's pretty easy to get the system up and running quickly. What's also nice is the built in data logger.
Another nice feature of the Commander 950 system is that the ECU can run either TBI or MPI, so in the future you can always upgrade to MPI.
I don't know of any TBI systems that offer and hand held programmer.
The link up a couple posts was close, but not quite getting you right there...
Programmed with hand held unit... no computer.
I like it!
Yeah, but this an MPI system, not TBI.
I guess I was mistaken on that part. Oops.
I would rather have a TBI setup... for simplicity.
Actually, I think this is what I was originally thinking about.
ANyone know what this would cost?
They are about $1400 at Summit. I've been eyeballing them also.
That price is another reason I keep looking at them.
Plus, I like the idea of being able to tune them without a computer. I dont like that at all. HAVING to have a computer handy to tune. What happens when somethign goes wacko in the middle of nowhere... no computer.
If something goes wrong, tuneable or not, you won't be able to fix it. You can't compensate for bad sensors, broken spark plugs, failed O2, etc., except some sort of limp mode, and I'd suspect/hope that aftermarket stuff would act just like GM stuff in that circumstance.
People tend to make a big deal out of "adjustability", but unless you have need to swap parts constantly (racing, etc) adjustability is a moot point. You get it setup right, and you never touch it again. THAT'S why fuel injection is so great. It's extremely consistent, and can adapt on it's own (starting from proper tune and within reason) to varying circumstances.
Of course, as expensive as chip burning is if you pay someone else for it, being able to tune it yourself initially MIGHT save you some money, depending on what the adjustable setups save you over chip burning.
For me... in an offroad rig for the wheeling that I do... I am a very simplistic person. Thats the reason I hesitate so much to do link suspension or anything major... I want simple fixes. Thats the reason I dont have fuel injection yet.
Carbs... you have spark, air and fuel... it will run, it will get you home. The more computer controls you add the more possibilites there are to diagnose.
Having said all this... I will probably have fuel injection next summer.
I bought my TBI (Pro-Jection) off ebay for like 400 - 500 bucks... just do a search for Pro-Jection and you will get a few hits.
since its just a TBI and a little ECU (with potentiometers - knobs) the kit is easy to tune and play with.
You will see them for sale here every once in a while too... I sold mine (lost my job) here to a fellow CK5'r
Pro-Jection is definitely the way to go.
I'll have to look on Ebay again. Last time I checked it was all 2 barrel stuff. With a mild big block, I dont want to choke it down.
I just want and little electric powered pumping carb.
Here's a link I saw to a four-barrel unit that has the knob adjustment that Topdown was talking about.
If you look at the pic of the ECU, you can see the knobs.
keep in mind that the 2bbl will support between 270 and 320hp in a BBC ...
Actually I e-mailed the guy about that one. I asked if was used so little, why was it so dirty? He doesnt actually own it, just Ebaying it for someone else, so he doesnt know why.
I will pass.
But, thats the one I think I will look for.
Well, I am around the 320hp now... and if I do anything it sure wont be for less power. So, I dont think I want to take a chance with the 2bbl.
