I suppose all these stand alone engine management have sample of twin turbo program? Gen 7 have a sample program that is for a 377ci twin turbo. I am thinking going to start off that sample for my turbo 383ci in a few weeks and will begin doing some street tuning. I have been practicing "off line from file" and reading I really like it and seem to be easy friendly user and awsome stand alone system.
mmvette, and Chris. I know both of you guys are using Gen 7 as well. Did you use the twin turbo program as a start or you created a turbo program on your own??
Hopefully in a couple of months, Rick will have his dyno ready so I can get some hp#. Man I am excited and I hope my motor won't blow on 25psi.
I am going to start with the 377 file and change the constants and see how close it is on my setup.. I am hoping some minor tweaking after that and it should be good to go. I still wanna learn how to do the diveability tuning and get that nailed down for fuel economy and clean burning while under light loads.
It is very a pity that at you not Big Stuff 3 - I can give starting 350 TT the program for you, if it is necessary.
I do not know as DFI GEN 7, but Big Stuff 3 is very easy in street adjustment - it is necessary to go
And to remove logging, further it to analyze and to correct in the necessary places map
of fuel for best A/F Ratio. Also there is a function "Learning" - it helps that itself
Corrects meanings fuel map on the given pattern of meanings A/F Ratio.

I bet Gen 7 is as good and easy to tune as the B3S. It can do all the above you mentioned. However The B3S do have a few new features, boost control and some others stuffs. With the price different is about $1000 more. I think I will be happy with the Gen 7 because it can do everything that I want it to do for my need.

You guys will find that the 377TT cal in the DFI sample files will be rich. I have used it and it does work OK. I am running the same starter cal on a 427 TT car. That cal is the actual cal for a Banks TT SBC that is supplied with a DFI G7 system.

Dear Bruce,
I to argue did not want that from systems am by best - I simply wanted to offer you
start-programm....
In addition to this - I consider that BS3 (BigComm) the program easier, is accessible in understanding easily and without excesses.
I looked Gen7 the program - it was much more difficultly looked.
One of advantages, because of which I have chosen BigStuff - there was just simplicity of the interface program.

Thanks for the link and all. surely the B3S is a better system. While ago when I call and inquired the pricing on the LT1 system and I was told $2400 or 2600 but I don't remember exactly. I got mine DFI for much less. I would appreciate if you send me the 350TT file so I can take a peek at it as well. Bruce383@rochester.rr.com

Good luck...
Also remember when you wipe out your 4L60 or 700, you'll probably want an 80E and that can be managed by BS3. PLUS there is now a Trans Brake for the 4L80E

Well personally this function in BS3 is not necessary to me - I to itself has established Rossler's TH400 HD w/TransBreak
Bruce, I just used the VE Table Estimator and it came pretty darn close. If I remember correctly I was running in the 12's for a/f. Recorded the run and changed things using the wideband feedback numbers.
Current VE * feedback number = new VE
.875 * 1.12 = .98 This is what you would do when the computer is adding fuel for you. The feedback number will be less than one if the car is running too rich.
