What are some of the advantages and disadvantages of each?
I have a turbocharged LT1 and will be purchacing one or the other in the next week or so. Which is more user friendly, options etc. Any info or opinion will be apreciated.
Thanks

 

Webpage has alot of informative info.

there is a 3 page thread over there in the ECM section that compares them and gives info both ways

do a search in the ECM section

 

Gen 7. I cna give you the number of a guy if you want to email me

 

Lemmie put it this way
We are dealers for both FAST and DFI, we make about the same about of $$ on either one.
I haven't sold a single FAST system since the Gen 7 DFI came out.
IMHO the Gen 7 is a far superiour system both from a intall and software perspective

 

does anyone have any experience installing DFI 7 into an LT1 f-body? how bad is it? i've heard the FAST system can be a pain during the install. i'm looking more into a plug and play setup than a cut, splice, and solder system. thanks.

also, does anyone know if there's a demo of DFI 7 anywhere?

 

Lowend: I mean this with complete respect, I looked into the two systems and I spoke with a couple of dealers like yourself in the same position who favoured the FAST. I might also add I spoke to one dealer that was a DFI fan.

Canadidly the most complete and comprehensive information I recieved was from Jack from Racetronix. I asked him what the differances were. I kid you not when I say that he spoke for 10 mins without taking a breath before I told him to stop. At the end of the day is said fundamentally there are some stengths and weknesses in both and that it was a close call. At the end of the day, for me, there was no clear cut "winner".

Candidly speaking I think it suggests that both systems are extremely good.

However, I do not know the differances from the installation perspective. I would have to assume that you have to splice a harness into the stock harness either way. No?

 

Haven't seen the new DFI 7 but I've always liked the FAST (Fel-Pro) setup better in terms of the interface.
I'm a little spoiled in working with Motec, Marelli and Zytek systems but FAST is a system that can handle just about anything you'd care to throw at it. I could say much of the same thing for the other. To me it comes down to interface and ease of use, from there it's a toss up. That is based on my experience with the last gen software.

Right click on this and "save target as" its the full software

 

Here is the best explanation i can give you on the difference's of the 2 systems:

FAST systems were built for car guys who need the control but will put up with some hiccups even though they are fuel injected. For those that have the FAST system you know what i'm talking about

The DFI Gen VII software is "supposedly" (this is hearsay) based on a very similar Ford OEM computer. If you download the "full" or "advancedl" version of the software on my site you will see that is has maps and options on there that are usually only seen in an oem type of computer. But most of those maps you wont have access to because when you get the gen VII you can buy 3 different stages of software: standard, professional, and the advanced. From what i hear you want the professional. Lastly the best explanation i can give to you is that the new gen vii was designed in mind for the carb guys who already have big blocks with huge carbs and dont want the stumbling, surging, anymore. They want it to act like an oem fuel injected car (hence the advanced/complicated maps of the gen vii). Where as us EFI guys will actually put up with a lot since we already started with it

hope this helped

 

One question, what's your site's URL?
I'm kinda in the same boat with my setup, gotta make a decision here real soon. Chuck tried to sell me on Motec but that's a little rich for my blood.
Thanks for the info.

On thing you need to be warned about with the GEN7 software is that some or all of your maps can be blocked from your view by a EMIC. This could be a major problem as I have seen many cars in my area poorly tuned with basic programming errors and basic mechanical problems not addressed that caused the car to run poorly by a near by EMIC. This was on the 6.0 boxes but none the less if you can't enter your maps that you paid for and they are wrong you are stuck.

Either system will work well if programmed properly. If you need some of the features the GEN7 has you are stuck for a short while until the new FAST system is available. My personal opinion is not to support a system that I can not enter after spending money to have my base program set by an EMIC. Regardless any statement to the contrary by Accel, the purpose of this feature is to make the purchaser of the GEN7 a repeat customer of the EMIC. The information I received from a reliable source is that many EMIC’s were looking for a way to increase revenue by programming.

 

see my link above

To Blownvette.....i can see both the pros and the cons of the locking/passwording of the Gen VII stuff

but honestly.....you have to admit there are some very complicated maps that even some EMICs shouldn't be playing with and the few who know what they are doing SHOULD lock them from the end user. There are really only a handful of maps the end user will really use and alter anyhow. So what's the big deal?

 

Sorry, what is an EMEC?
