olenuskool wrote:Guys, Newby here so please don't flame too much. I've talked a lot with k&n about this deal and did quite a bit of research on this, fitech and sniper too. (I googled k&n eci and this forum came up. As a former happy JGC owner; I am a Jeep-fan & decided to join.)
After weighing my options, getting 'real' prices for everything needed for all of the efi and eci units, I've decided to order an eci next week for my 383sbc street rod. Out the door, it comes in at about half the cost of efi, it's completely made in America (at least for now) and I like my carburetor. I'm looking forward to finding out how close to efi-like I can get it.
Thank you for the add and I'm happy to share info from the tech at k&n if you're interested.
Apples & oranges I guess. I enjoy working on my carb but to be honest; I like the way efi starts & runs at low speeds. If the eci will do what I think, it will help my decently tuned carb to start & run as well or better than efi, I'm hoping to get the same mileage and I've saved several hundred bucks.babywag wrote:Wow...I just don't see the benefit of this? It isn't hard to tune a carb to work properly.
My opinion, save a few extra bills and just install a real EFI setup.

Carburetors are actually pretty smart. Most of the features of efi systems are to make it do what a carb already does.
Wow. You've got a lot going on with that wagon! If you're going full-on efi, I suggest that you spend some time checking on actual costs of everything needed. I did and it was eye opening. For instance; in addition to the sniper efi system, you're going to need this too: https://www.youtube.com/watch?v=juJlPruQGq8Rinkle_Stinkle wrote:olenuskool wrote:Apples & oranges I guess.

I'm just curious to see how it performs and the reviews I get. I'm still considering the EFI upgrade but right now I have an engine I need to buy along with performance parts, new exhaust, new tail gate kit for the window, fix 3 windows and lock actuators, new paint and new wood vinyls. At the very end of that i'll drop the tank and replace the fuel lines. so honestly every penny counts and even though $600 extra may not seem like a lot you also have to consider the time of install as that costs money too. I think when I get to the tail end of the project I could seem me splurging on a true EFI system (time and money) but for now I honestly believe this is a quick fix for a constant nagging problem.
but that's just my thoughts.
Now, if I fall into some extra funds you better believe id immediately purchase a full and true EFI. but I got to make those funds last in order to keep this guy on the road.
So detune your carb for the ultimate benefit LMAO.olenuskool wrote:They suggest slightly leaning the idle circuit and main jetting for max power or max mileage, set the afr thresholds and go. There are separate afr settings for idle & open throttle.
The engine has 166K on it right now and sat for many many years before I got ahold of it resulting in a very loud lifter tap and I mean LOUD (no its not exhaust leak). I'm about to purchase a 96K engine that's running like a top to swap over. I'm going to pull the original and rebuild it slowly over the next year or so and include RV CAM, New timing, aluminum heads, hypereutectic pistons, etc... that's where a lot of my money is going to go right now. Once the engine is built I'm going to pull the old/new engine, add aluminum radiator and probably end up of fixing my wiring harness and clean that up. Pull Heater blower motor and AC motor and clean those up while I have good access and probably fix some times I'm not expecting to. Scrap the exhaust, replace front fuel lines and maybe the brake lines and throw the rebuilt engine in. Add exhaust, drop tank and only then will I actually work on the fuel pump, skip plate etc. I'm going to upgrade the fuel pump to get ready for whatever fuel ignition conversation I go with.olenuskool wrote:Wow.

When you ask around about the fitech kit, the end price gets up there too and problems are beginning to show up. As they say, there is more to the story. I'm also not a fan of China-built car parts. (Sorry, just stubborn that way.)
looks to be a toss up on that forum too... lots support it and lots don't.babywag wrote:So detune your carb for the ultimate benefit LMAO.olenuskool wrote:They suggest slightly leaning the idle circuit and main jetting for max power or max mileage, set the afr thresholds and go.

Whole lotta $$ for very little IMHO.

Detune by slightly leaning the mixture? Please help me understand your thoughts. It's been my experience that slightly leaning most carburetors gets the engine closer to stoich which makes more power, but also gets closer to danger. I hope that my inputted afr value to the eci keeps it safe, fast and efficient. We'll see in a couple of months.

The reason for leaning out the carb jetting is to allow the unit to enrich the mixture to Stoich 14.7:1 (Or thereabouts). When power is the main focus, a 12:1 mixture (With proper timing) builds more power than a lean one. I doubt this unit has the ability to sense manifold absolute pressure, mass air flow and other key features that make EFI so quick to adapt. Like I said previously, it seems to be a 700.00 replacement for a proven choke system.olenuskool wrote:Detune by slightly leaning the mixture? Please help me understand your thoughts.

Your stoich & afr numbers are close. I do not intend to lean my carb to stoich, probably closer to 13:1 to begin with and use the eci from there. And since the carb functions as it is designed (utilizing manifold absolute pressure [vacuum], mass air flow and other key features to operate) why would the eci need to sense those features? I see the eci as a fuel-trim or supplemental device to the carb, not a major supplier of fuel. I'll bet it provides less than 5% of total fuel needed.Tatsadasayago wrote:The reason for leaning out the carb jetting is to allow the unit to enrich the mixture to Stoich 14.7:1 (Or thereabouts).
