Thanks for the info. I'll keep looking around too and see if I come up with something better.

I was really impressed with the new FAST EFx system. I would be very interested to see how the BIG STUFF is to tune.

I am big into "auto learning" systems with Wideband O2s.

My LSx engine will be 950 driven. I'm using FAST's eDist to drive the coilpacks. I'm still getting the engine and car together so I can't claim to have "played" with it yet.

But I will.

Jody,

I started with the original CALMAP from the early 90's. Have also dabbled with the FAST.

I currently have the BIG STUFF 3 unit and harness for Chevy 2 project. I also agree that this unit is the latest and greatest from John Meaney. He really knows these things.

From playing around with the software on the laptop, I already like the menus and these ease of use! Time will tell!

guys I've also received my BS3 and I'm just waiting to install the engine to finish the efi installation. It seems like, if you've used FAST then there should be no problem using the BS3. Menus are very similar plus it has the learning option.

I selected the Edelbrock Pro-Flo for my big block EFI in my 69 Vette. I like the fact it is about as simple as it gets. Granted there are fine tuning items that are not available and a complete engine system change would require a new base cal chip to be burned. However, from there is it simple plug and play. I love the hand held tuner control box that makes real time instant changes and displays engine function with a green/amber/red indicator light to see rich/lean at a glance while cruising.

On my LSX project in the 69 Camaro I am really on the fence. I made some major mods to the car with SLP Stage III heads/cam/35# injectors/2,800 stall, etc. SLP uses Fastchip.com to program for $450 a pop. I think they lock the program once complete. They have a good reputation with SLP and seem to be confident of producing good results the first time. The other option is to go with hptuners.com or other type source to be able to log in and tune it myself. The problem here is they do not supply any baseline info or basic programs to get started. It is all learn as you go.

So, to answer you question: Yes, I do mess around with this stuff, and NO, I really don't like all the time and effort to compete the fine tuning details.

As far as chassis harnesses, I have done the Painless generic gm 18 circuit many times now. It is true you have to come up with your own ends from your stock harness for blinkers, tail lights, etc. However if you are running aftermarket gauges, a/c, and stereo, you will want to build your own ends there anyhow. It is very time consuming and requires thinking through the entire electrical system as you go always leaving room to grow as you think of additional things as you go. Tieing into a EFI system is a breeze as you usually are only integrating ignition, battery, grounds, and coil power.

I too have played with the Accel DFI 7.0 and must say that they have the worst technical support group that I have ever come across. I wouldn't mind tuning with their software if it gave me a great end result but when their tech support cannot explain to me why I'm getting error messages from parameters I'm not even messing with I get annoyed.

Jody,

I did a Holley Commander system a few years ago. It was both easy and fun to tune. tx for the invite over here by the way, cool place!

**camcojb** · #19 03-29-2005, 06:35 PM

Thnaks for the info Jim. I have never tuned the Holley system, but have heard very good things about it.

Jody........

How long do you think it'll be before you have the chance to try out the BS3. I think I'm about ready to upgrade..........But want to move on to the easiest and friendliest system out there. Looking at the software......would you say it's easier than the Fast.......Ya'll already tallked me out of the Accel 7.0

..........and I've heard a lot of good things about the Fast.......but I figure since BS3 was created by the same person.......maybe he made it even easier.........

Any opinion?
