Yeah I forgot about that part. I am a software engineer so I have 3-4 laptops lying around my house. The megasquirt actually works better with an older laptop becasue it needs a serial port. Most newer (2-3 yr old) laptops don't have serial ports because everything is USB now. You can use USB adaptors however numerous people have reported strange behaviors when using USB.
I am using a pentium 233 megahertz that is about 6 yrs old.
Good thread. I will be dealing with the EFI issues on my 66 [KB twin screw] and didn't realize initially all of the ass'd costs for fuel systems. I am a bit concerned about the size of the fuel pump...not sure if the A1000 will handle it or not [seriously]. Also, I am undecided about megasquirt vs. TwEECer/stock computer.
For my 2+2 [if I actually get around to it rather than just keep it sitting as an investment] I really WANT to do a turbo. I love the idea of a 427/460 small block, but realize that a turbo would be massive fun. If I get the efi stuff figured out on the 66, it would certainly make the 65 easier to do.
Man do I LOVE fast cars!!! Been doing some paint/cosmetic work on the GTO and have been commuting in a Chrysler Sebring...bring me HORSEPOWER!!! Then again, my GTO has made the wife's WRX feel really slow...something about 500+rwhp in a V8 that will just "git 'r done".

I am sure you have posted your build and I apologize for not remembering the specifics however I hope you are planning on an aftermarket block because the A1000 will support an efi 800hp forced induction engine. Obviously that is well beyond the capacity of a stock block.
Sounds insane to me. That's my kinda project
The plugs are at .025, I think. Or maybe .023iskwezm said:
The car would lean out real bad. It would go from 11.5 for a sec, then straight into the 12's. I jet up, then it starts at 11.2, then would go to 12's. It was a combination of things that made it a little tricky. My venturi;s in the carb were too small. Just not enough signal. I went back to a stock 650 main body, and changed the high speed bleeds. The fuel curve makes EFI jealous.
Right not it's a litle rich when I step on it. Then it flattens out and slowly climbs from 11.5-11.7If I were building a low hp say 500hp and below motor then yes I'd go EFI but for say my 408 I think I'm going to sell off my EFI things and buy a csu carb.
I will be able to buy an intake carb carb hat and correct dizzy and still have another 2K to spend after I sell my efi things.
I wouldn't use stock ford electronics nor a whimpy gt40 intake. I'm talking victor spyder intake, 86mm tb, 83lb injectors, billet dizzy, big stuff gen3 management.

It would be near impossible to use an FMU on a high power engine and get the fuel curve right anyway. If you dont mind using the stock EEC-IV ECU, about $150 will get you all the stuff to edit binaries/program a chip and run it through the J3 port like a twEEcer. I have a thread in 5.0 Tech about running an EFI computer from a PC(can also be done) and all kinds of info came out of it.
On the other hand, I wouldnt convert to EFI just to run a turbo.
Well you definatly would need a tune for anything over 300rwhp or any kind of performance mods to perform tip top and about 500 is the limit more than anything because the need for big injectors come into play.
The bigger they get the sloppier they are in high impedence mode. So you get a driver and the tweeker and a wide band by that time you could have spent a few more bucks and bought a good engine management system.
With lots of support and even more features than stock electronics. In addition to this you get it in one simple package.

lol... cant believe some of you guys remeber my stuff from 3-4 years ago. Anyways, thats a different car and different motor. That was for my 69 coupe 393 stroker. This turbo setup is going on a 302 68 fastback
xo don't bother with a 302 go straight to the 351 if your using a stock block. We broke one in half running 460hp to the wheels turboed. General thought is anything greater than 500 is gonna go sooner or later. And by broke in half we had two engine blocks after that, only thing holding it together was a main girdle.

im not to worried about it...its a stock roller forged motor. I have seen these motors take up to 12psi with 150k miles on them as a daily driver.
Mine is a B50 'sportsman' block [about like the old mexican blocks]; forged 331 bottom end; AFR heads; big blower cam. To run the KB requires a Ford intake, so I have a Fox-Lake stage III ported GT40. Bought it off a guy turning some amazing times in a fox-body. Looks funny on the underside as it has so much fill to replace the machined-out metal.
The A1000 has reportedly shown some UNDER performing with forced-induction. No firsthand knowledge, so this may just be internet rumor-crap.
I really need to learn more about the TwEECer and capabilities of the stock system. 2 yrs ago I was on a spending spree, and got one new [off this board] but it has been sitting...as has the 'vert.
Part of my problem has been this:
Nothing like running a 6 speed HEAVY car on a slick strip. But the best trap speed was ~119 just running 7psi boost, so it was fun.
And just to show the garage is TOO SMALL:

Are you guys talking about the aromotive 1000 pump?
Those things are crap in my book. I run Magna Fuel Pumps.
Also I have a tweeker in my 67 coupe and for what it is, I do agree it to be better than having to have someone chip tune it. Then being stuck to that tuner forever. It takes a few hours to learn how to do things and of course a few more to figure out what you did wrong LOL.
