aftermarket EFI tuning - Lateral-g Forums

**camcojb** · #1 11-23-2004, 12:05 AM

Anyone else into aftermarket efi systems? I've tuned FAST, Accel Gen VII,and done some prom burning on a 93 Vette with a program from The Turbo Shop. I just bought a Big Stuff 3 system for my twin turbo, the newest system from John Meaney.

Anyone else enjoy playing with this stuff?

I'm still in the stone age Jody, but will have the Banks set-up and EFI on my car (if I can ever get it done! lol) and I'm dreading the day that I have to figure that stuff out.
There is only one shop in town that has a chassis dyno and does tuning, and I'm not even sure of thier background.So I've often weighed the option of loading the car on the trailer and hauling it to a reputable shop in the lower 48.
BUT, that point of the build is still some time away for me, we'll see!

I'm still running my old 6.32 DFI..............I've tuned the motor naturally aspirated but am scared to try and tune the twin turbo........I can't really afford to build another motor........

So I'm actually considering moving on to something more friendly and simple.....I've heard the new 7.0 version is pretty simple and have also heard some good things about the FAST system. Haven't heard anything about the Big Stuff system thought..........

Which one would you say is the easiest to work with..........keeping in mind that my system is for all out driving and not just racing.

The Gen VII is not the easiest to tune in my opinion; it's actually the toughest in my experience. Has a lot of control and is a nice unit, but I know several dealers who've dropped it because of the complexity. The FAST is pretty simple in my opinion, and I've heard the Holley 950 Commander is as well, although I have not tuned it. I just received my Big Stuff 3 and have had a chance to look through it. It looks awesome but can't give an opinion for a couple of months until I tune it on my car. It is designed by John Meaney, the same guy who developed the FAST system.

I'm still waiting on my Big Stuff 3 from FORCE and am encouraged that you are using it also. I am running 58 lb injectors on a 383(I have as of yet to build) and you know the rest, twin turbos, AFR's, etc. Are you getting the unit with memory?
I will need some help with my unit once it is installed. Did you use a new harness for your project (Painless,etc?) or did you utilize the existing harness.

I'll be glad to help and hopefully I will have mine tuned by then. The unit comes with it's own standalone harness which you can integrate into whatever wiring harness is on the car.

I am installing a new harness as I am incorporating Power windows, seats, A/C, fancy radio and a bunch of other stuff influenced by this web site. This one may suck the life out of me.

Of course I have a 55 chevy to build...

Who's harness are you using? I have not made that decision yet and I also have A/C power windows, and a lot of electrical options.

I guess ia m going with a painless harness. Here's what I can't figure out though, Painless has a COMPLETE kick butt harness for a 68 with all the plugs, clips, etc and I can get it cheap, but, Painless has a "HotRod" harness for 69-74 GM cars. 18- 22 fuses. Go Figure. No offense to you 68 Guys.

Shame is that you have to use your old harness to get the plug ins for all of your stuff (unless of course you splice in harnesses for all of the components). There is a heck of a lot of sautering (SP?) unless you want to utilize a bunch of weather proof clamps.
