FAST Programs?

I have just gotten my Typhoon back from RPM in Cali, and am absolutely fascinated by the million parameters to adjust with the FAST system. I am wondering if people could e-mail me some GCT files of well-tuned trucks? I realize there are a million different variables, and my truck (Vortecs, 422, 50#, T-66, A2A, manifolds, billet crank, forged pistons, 4 bolt, Eagle rods, Cometics, 3" dp, 6AL, eventually methanol inj) is probably lots different than others...but I'm just interested to see where everybody else's tables ended up. Or is there some prohibition on sharing these files? It would be helpful to tell me the build of the truck, too. If anybody wants, I can post my current GCT, too.

Re: FAST Programs?

it is somewhat differnt that you have a fast box with such small injetors but I know somebody will send you something very soon. I would send you one myself but all my fast programs are 74# and up.

Re: FAST Programs?

Mostly I went FAST because I wanted to be able to use the 422 cam and the bigger turbo. I didn't think far enough ahead way back when I bought the 50#'ers. Still, I'd love to look at the 74# programs, too.

Re: FAST Programs?

pm me your email and I'll get it out to ya. it's also tuned very close to your 422 cam.

Re: FAST Programs?

I got files from my previous build with L35s from KB (ported) and T67 P trim, KB A2A , and 75s. All you have to do is change the Lbs nr in the Fast programm.
Ill be back in town tomorrow so if you still want it PM

Re: FAST Programs?

I would also appreciate seeing others finely tuned FAST programs.....

internal mods, Vortecs, 422, TE63 w.85 PTE th, 75#

My current config (strret/strip combo) when viewed in the graph mode looks like ......... well, I'm not exactly sure WHAT it looks like.

John, I would also like a copy of your tune, and any others willing to share.
TIA

Re: FAST Programs?

Thank you John for the 83# program. I thought it interesting on A/F ratio.... yours goes 14.0 to 13.5 to 12.0 to 11.5 to 11.6. My current program I'm using is much more gradual, but ends up at the same place. <---- I'm unsure which way is best, but here's a perfect example of two dfifferent methods of doing the same thing ;-)

I also noticed that you have "correction limits" working hard in the fourth and fifth row, where I have mine working at the upper rows. Why did you limit adding/subtracting fuel there?

Timing: If memory serves me correct, you have aluminium heads now John..... Is the 18/16* timing on the top end what you used on the 11.2 pass? I have the steel Vortecs, but run 20+ degrees of timing on pump gas with no knock. These Vortecs will take the timing, even under boost.

Bill Jenkins: Are you interested in trading current usable programs? Also, fyi on the injectors...... you DO need bigger. I had 55's with my current build and had to to to 75's due to high injector duty cycle at only 18 psi (mid 90's)

Anyone else with a useable program wanna trade files?

Re: FAST Programs?

Yes, I'd love to trade programs...is there a place online we can upload these things, so everyone can see them? I can upload the one I currently run my truck with. I have some very severe knock issues (at 12 psi!) and it probably looks screwy under boost, and there are some other drivability issues too...but I have it if anyone wants to look. I'm thinking maybe my 50's weren't such a good idea after all. I chalk that up to mission creep...I went from a simple "Ultimate/cold air" mod to full-blown forged/FAST within the span of 6 months.

I'm using CCOM 1.005, how do you get the "graph mode" for the fuel tables?

Re: FAST Programs?

I have the non-windows (old) version of FAST.... unsure exactly what revision it is. Using the non-Win, when viewing your file (a/f ratio, VE, etc) press G on the keyboard. It will then give you a graph, and you can turn it around using the arrow keys for different views. To get out, ESC.

I'll copy my existing file on a floppy and forward it on to you. (gotta find my notes so I can remember how to do that..... red face) Please do the same. Just send it via e-mail.

I wish that more of the quick FAST users would share their programs..... there's lot's to be learned by looking at them, and then discussing "why'd ya do this".

Re: FAST Programs?

Hey guys,

bill and i are kinda at a loss to this detonation issue.. Basically the truck at 12psi will audibly knock on 91 octane. Goes away with 100, but then re-appears with 14-15psi. Even pulling the timing back to 14deg and a/f at 11.0-1 it seems to still ping. Almost like it has 14:1 compression. Truck runs extremely hard with only 12psi, and a/f seems to stay steady. I would tend to lean towards some sort of fuel delivery issue, whether it be the small 255 fuel pump or possibly injectors, but at the same time i would expect the a/f's to go through the roof. I told bill to verify the timing again (via laptop and timing light) and he says they are consistant so i'm at a loss here.

As for the drivability, i thought that was due to the bad IAC motor? Thats pretty easy to fix, as long as things are consistant.

Re: FAST Programs?

Bill: need an e-mail addy to send the file....

Nightdriver: couldn't open the FAST file, guess my "zipper" is stuck..... therefore I just "like" you at the moment ;-)
What info is in the link?

Mike: the audible knock is unusual with the Vortecs, especially at that low of boost. I'd almost suggest upping the timing, and carefully giving it a try. The 255 fp should be more than adequate for where Bill is at. Bill could download my file, load it, change the injector size and TPS setting, then try it to see if by chance the problem is program or truly engine related. <---- doubtfull it's the program, but I know nothing of it, so perhaps there is something there causing a problem.

Re: FAST Programs?

The "drivability" stuff is nothing serious, it's just a bit balky on startup. It idles like a dream now, but it seems to want to load up a bit when it's cold. It also seems to load up very easily if it's very hot. It seems to have a few "flat" spots at the low end under partial throttle, but again, nothing serious. It's the top end that I worry about. Part-throttle anything is light-years ahead of my carbureted V-8 Fiero. I should have been a bit clearer with the "drivability" comment...

I will PM you (Roland) and try your file once I get it. I know what destruction detonation can cause, so I'm very leery of putting my foot into it!

Re: FAST Programs?

come on......this is the latest windows update. you can even use the L button with this version. Also new help file.

I know Mike has tuned a lot of Fast ecm trucks so i guess its something else. I would do a compression test , top dead center verification,take a look at the spark plugs.
I need a datalog file with the sensors i told you.

Re: FAST Programs?

Thanks Nightdriver....
but I have the old DOS version and the windows update wouldn't do much for me. I tried it (windows) on a friends turbo Buick, and didn't much care for it. I actually prefer the DOS version as it's easier/quicker.......

So, would you mind e-mailing me your program Nightdriver?

Bill: you have mail.

Re: FAST Programs?

ok i will.
i had to dig but i found it. Remember to set up the idle valve and change the injector constant.
I will also email the T78 file . There is a lot of fuel missing at the boost area cause i use A LOT of pure meth under boost.
The T67 file is without meth so you can "drive"it
