EFI requires a computer AND a screwdriver.

 

What I find funny in this conversation is the MPG argument. I've never calculated MPG for my '71. I didn't buy a Corvette to worry about MPG, I bought it to drain the tank as fast as I can.

 

And yet your considering installing an overdrive unit on your car?

I dont see a MPG "argument" Its been mentioned as its one of the perks that it can regulate fuel delivery better and therefore offer better mpg when set up correctly but its possible to have a carb dialed in to deliver good mpg too.

We like to joke and shrug off the cost of actually being able to use these cars but at the end of the day for me when I have 3 other vehicles including an 8,000lb lifted truck that are all cheaper to drive when it comes to sucking down the dollars at the pump and actually having to stop and fillup on my commute all the time, If I can get better MPG as a perk of an upgrade im making then great!

I dont want to get off topic but its very possible that in the near future we are likely to see some negative effects in fuel costs as gasoline vehicles become less common. Hopefully im wrong but I had the same thought process when I converted to solar 6 years ago and I no longer have to pay for my electric at home but I see the costs have climbed significantly at my business.

For discussions sake the system I bought allows quite a bit of basic tuning from the includes tablet screen... The advanced tuning would be more akin to the purchasing and changing of the components such as air bleeds , metering blocks and accel pumps and cams and such. And in my case I already own a few laptops. I even keep a spare in my garage for tuning and programming my EV/camping golfcart.

 

[QUOTE=4-vettes;1608109097]I get your valid point and understand thats alreadyhow I understood it myself.
This system has 2- 02 sensors btw one for each bank so for one thing the whole open divider single plane/vs dual plane issue is not as much of a concern and I believe a person could possible still dial each cylinder in a bit better by checking plugs but I could be wrong on that. I dont recall any MPI cars that have 02 sensors on each cylinder but I could be wrong about that.
I am going to stick with the system I got as long as I can modify my CAI to work and fit under the hood as mentioned in another thread its a "Slippery slope" with upgrades on this vehicle and I just need to draw the line somewhere. at least for now. maybe ill decide to upgrade again at some point down the road to see for myself what the actual tangible benefits are

 

mine is still sitting in a box on my den floor as I continue to accumulate parts and hope for a couple days of freedom to start the install.

One thing that was frustrating was that I purchased a new baffled fuel tank along with the sending unit and intank walbro pump and no where did it mention the gaskets which it did not com with. I had to search for and purchase them all separately. the pump and sending unit options ere all linked with the tank though..
Looks like your using the same intake as ill be installing polished and all. I ported mine to match the heads.

I already locked out the original GM tach drive distributor which has a hall effect pertronix installed by the PO for the old L48. I will be using this with the aces control mainly because I dont want to replace my tach.
im also still planning where im going to mount everything under my hood and im curious to see what you do in this regard.

BTW looks like your car is the same color as I painted mine..

 

Not for MPG but to lower my RPM on the highway so my engine isn't screaming just cruising at 80. Everybody's situation is different.

 

[QUOTE=augiedoggy;1608109463]Augie - the Ace's system has two O2 sensors one for each bank? That's an improvement over the other systems already...

 

[QUOTE=Halfnium;1608111291]Not the "killshot" TBI setup no... that only has one. The $1,600 - 8 injector system I linked above has 2 sensors.
