Fast XFI or Big Stuff Everyday Driveablilty

[quickt]

I looked at it the same way. I bought my DFI Gen VII last year with a new O2 for $1000 with the Buick harness. I would have had as much or more for the Maf-pro and there are not many around that can help me tune that when I last checked. Lonnie has my DFI tuning duties if I ever get the "roller" put back together!:biggrin:

Looks like I will be moving to that area in the Next few months. Mulberry area. Details to be announced. :smile:

I just hate to see guys spend 1500+ on a aftermarket ecm for an 11 sec car...

Kinda like the ole Mustang LX V6's with duals:biggrin:

Lol.... nice.

I personally like the FAST

Lonnie that is about 20 minutes from my house. Let me know if and when you move. Are you still going to have a dyno to work with for tuning if you move over this way?

 

[quickt]

I will cut a deal with some one in the area. Yes even if we need to go to indy.

 

[nastynavy]

Sounds good. I hope to have it together for the Nats but I am not sure if it will happen. I will email you to schedule it in......eventually.

This is how I feel about aftermarket ECMs on an 11 second car. If you're like most of us, you will not stop at 11s, if you haven't already got the bug. When you taste 11s, or the competitor next to you blows you away and he's doing 10s, you will want 10s. You might as well start getting used to the new system on a safer setup now. That way when you head for the 10s you'll be ahead of the curve. You might even meet up with that same competitor and blow him away with your high 9 second run. Go get 'em!

I have to say I was a little neverous when I decided to jump on the XFI side. I am glad I did now. The car acts just like it still has the stock computer. Granted you may have to do a little tweaking to it, but it is not that hard to do. What help me is I bought the FAST DVD they sell. That cleared up a lot of things that may seem intimidating. The DVD is a little pricey but is well worth it!! I am glad I made the switch!!
For what it is worth I started a thread a little while back on this subject. Search under, Stock ECM or Fast XFI???

one question..would you let your wife take the car for a few days ??? driving anywhere and everywhere for say 300 miles or so? would you be comfortable that the car would run fine ??? oppps...thats 3 questions :biggrin:

Great post. A post with no bashing. Maybe this should be a sticky since it's so rare....

X2 .. I know all the aftermarket systems have some kick ass "options" that we can't do with a chip. BUT in another few years Buick "restorers" will be taking over then everyone will be looking for the stock chip with the right "code" on them

I can get by with the XFI and cant stand the BS3. QUOTE]


Why dont you like the BS3?? Could you elaborate? Thanks

My mother has drove my GN for a few days with no issues except for the time she called me about what kinda gas does it take. so after that when she needed to drive it i just lowered the timing and added some more fuel just incase mode


i actually named that program Mom's 87 tune.


I'm not married thank god

BINGO that is exactly how i felt
i wrecked my last buick which ran 11's all day long with a max effort system
now that i have my new replacement gn i had the same frame of mind and bought xfi from Hartline performance as one of my first mods
talk to cal... he really helped me sort things out right fast!!!

WOW I would love to answer that question. I dont want to start mud slinging contest. I can tune the XFI but dont know the little tricks in the software for ironing out driving issues so it takes me longer to work out bugs but I can handle it. The Accel and Electro I know inside out and know all the little tricks. Motec not too bad either. The BS3 IMO is warmed over Fast Classic with old out dated software. Tech help if you are in a pinch is non existent and if you do even get the arrogant return phone call you will be treated as if you are an idiot. Warranty forget it. I can go on and on as to other issues with the unit but I have posted enough to bring out the BS3 guys to blast me as it is. All the systems work. They all have good and bad. Do your home work if you are buying make an informed decision and disregard info from those who have not used a system they say is inferior. Helping a buddy once does not qualify IMO someone to really have a honest evaluation of a system. Yet some will run their wiener cleaner as if they know all there is to know. Talk to people who own and use the systems you are looking buy. Example: Ask Jason White how well he was treated with tech when he owned a BS3. Beware of salesman who do not sell other systems and can not give you an objective opinion as to pos/neg of each. Those guys do what is called SWUG. (Sell What You Got) Last but not least dont take info posted in a thread like this one and run out and spend your money. Everyone will be throwing darts for their favorite.

Well said. That sums it up in a nutshell!

wow-----looks like to me we are comparing a lot of apples to oranges------can we take a F.A.S.T. (or other modern EFI controller) on a highly modified car and make it run as streetable as a stock ecm on a mildly modified car-------thats sort of like asking can we treat a tiger like a pet cat and have it behave like a house cat--------i am not an expert tuner by any stretch of the imagination but i am a really good electrical engineer and have a modest amount of common sense logic---------that said i realize the merits of the stock ECM and pay homage to the thousands of design and programming hours that went into the stock ECM and operating system code--------BUT it is an early 1980 era computer-------it shares lineage with the DOS IBM, Radio Shack TRS 80 and Commodore 64 for those of you that even know what these were-------many of these newer aftermarket ECM's share the heritage of Pentium dual core processors that run at speeds that were found only in large Penatgon supercomputers in the early 80's-------the operating systems and calculation speeds of these new systems make it inconcievable for me to believe that they cannot outperform the older OEM ECM's if a reasonable amount of time is spent optimizing the program-------a FAST XFI can probably calculate pi to a thousand places between injector pulses--------one thing I do know for sure------at my last open house Jack Cotton was kind enough to install a XFI on one of my daily driver GNX's-------it has simple mods------36 lb injectors, TA 49, mid 90's ATR downpipe with external wastegate, Reds fuel pump-------he spent less than half hour tuning it-------car runs like a proverbial Swiss watch AND bat out of hell--------why is that not a surprise to me??????--------look what computer related items have done elsewhere in the last 25 years--------even if all you want to do is type a simple letter and print it on paper look at the difference in a early 80's DOS IBM and a modern Pentium dual core computer running OFFICE software--------wanna really put it into perspective?????? internet technology circa early 80's was DOS operating systems interfaced with dial-up via Compuserve..............RC
