Well, on the day before Thanksgiving and I received a Thanksgiving gift!
The new XFI version 2.0 will be released in January.
So you may say, "So what".
The EZ-EFI system have been selling very well because they are self tuning and they really work.
But some users, especially racers, needed the power, and fuel flexibility of the full XFI system.
But the XFI required lap top tuning, and not everybody was comfortable with that.
Well - XFI version 2.0 adds the self tuning algorithms of the EZ systems to the XFI.
What this means is that you get all the benefits and flexibility of the XFI system yet
IT SELF TUNES ITSELF. What more could you ask for?
There are a few things that racers have been asking for so FAST has added those too:
* Multiple rev limiters
* Progressive boost control
* New power added algorithms
* Improvements to the traction control algorithms
* Special "test" mode to make timing setup easy
* More accurate warm-up tables
* Automatic TPS calibration
* Improved on-board diagnostics
* User control of low battery injector compensation
ETC - ETC - ETC ...

FAST XFI-2.0 Part Numbers, Pricing, and Upgrades
Newly purchased XFI products and part numbers stay the same with NO PRICE INCREASE.
If you already own a FAST XFI system, and want to upgrade to version 2.0, there's no need to remove your box or ship it anywhere - unless you want a new case.

The 2.0 upgrade is a firm-ware and software change only.
If you want to use a new feature, that requires a new wire in the harness, I will provide extra pins that can be added to the existing connectors.

See my web site www.fastmanefi.com for more information.

F.A.S.T. is doing some truely amazing things with their fuel injection. I do not know why someone would use any other company, or look for anyone other than you to purchase their injection needs from...

Sounds good Rich,

Hey I still need to get a tune from you for the XFI I got for the 6.1 Hemi in my buddies Power wagon.

Still waiting on the body and wiring it up right now.

Maybe early next year.

Send me your ECU serial number (and $70) and I'll get you an upgrade to 2.0. Then the system will be self tuning...

Rich,

You mean my tuning woes may finally be over.

I will be able to update the system that I bought from you back in 2007.

What do I need to do to update my ECU?

Are there an hardware or wiring changes that need to be done?
Please let me know.

As you know, my project has been pretty much on hold since our move from Illinois to Arkansas.
Things are finally getting to where I can start working and playing with my cars again.
This could not have came at a better time for me.

Herb

I am 100% going to buy an EZ-EFI system for my car when I get my bonus in Feb, I probably don't need the XFI, so I will be happy with the EZ. If there was any way I could come up with the money now, I would do it.

Email me your ECU serial number (found under View/System Configuration), along with $70.
I will send to you a new version of the C-Com software for your laptop, and a firm-ware upgrade that you flash into your ECU. You better read up on how to do the flash - it's section 26.0 in the help section on your C-Com software.

Are there an hardware or wiring changes that need to be done?
No hardware changes. The main harness has a few more inputs and outputs, but those are only for racers that need the extra rev limiters and turbo control. No hardware changes for you.

Rich,

By the way, I saw you on an old Rides episode on TV today. The one with the "Xtreme Lee"

I will get the ECU info for you.

Thanks,

Herb

Fast man,
If I have the MOPAR AEM efi :( would I be able to change the ecu plug to the xfi style or would I need to change the complete harness?

The FAST system shares very little info with AEM. You'd have to change the harness.
But the AEM is a good system. You should be able to get that dialed in.

It runs good just a little hard starting several say its a design flaw with the AEM's. (something about the crank sensor has to make a complete revalution) After it cranks a few seconds it starts right up I just wish it was a little faster, Like a stock car, does the fast efi do the same thing?

There ya go ,Herb !

I saw Fast Man's "ad" and I immediately thought of you . I was gonna PM you but I see you were sleuthing around too and you are all over it !! Hope it will help you with the Dart being the wrong kind of " HOT" !
Speaking of hot weren't we just sweating at Falbe's the other day ?----------Brrr!!!
Good luck ---will look for YOU on " Old Guy Rides" -- Mopar Tom
p.s. -ever hear from Jay ?

Yeah, that's true. AEM requires two complete camshaft revolutions before it's happy and ready to start. Most EFI systems used to be that way.

FAST is not like this. The EZ system doesn't use a camshaft signal so it hits the injectors in the bank-to-bank mode immediately at crank. Starting is usually pretty quick.

The XFI system used to wait for the camshaft because it needed that info to sequence the injectors - just like AEM. But that changed about 2 years back. Now the XFI uses bank-to-bank for starting and then switches to sequential after start.

It will be a couple more months before I get wired up to get a serial ##, but I will get with you.
This will simplify the tuning on the 6.1.
Thanks Rich

Fast man so scare me how much is this new setup?
Harness with updated xfi ecu & what ever else I may need to switch over.

Thanks
BOO !

It depends on your intake of choice (choose one already set up for EFI port injection), sequential vs bank-to-bank injection, HP level (determines injector size), etc...

But a typical full-bore system uses a 4 barrel manifold for a 4150 style carb, and a FAST dual-sync distributor.
ECU $1600
Main harness $350
Injector harness $125
4150 style 1250 CFM throttle body with TPS and IAC $540
Dual-sync distributor $399
Injectors (depends on flow level required for HP) ~~ $400
~~ about $3400 total.

You can remove $400 if you use a modified MSD distributor and run bank-to-bank.
Or if you use a crank trigger you can use an MSD to go full sequential.

Or you can go with the EZ system for about $1750 and just bolt it on.

Thank you fast man but I guess I should have been more specific with my question.

6.1 hemi stock efi type setup currently has AEM running on it.
So I would need the ecu ($1600) and what harness ($400)?
I have the MOPAR 392 cable driven throttle & o2 sensors also.
Anything else?

What about a tach signal? Does the xfi generate one or will I need to add something?

Well - - - Yeah !! A 6.1 is a entirely different game...
The FAST 6.1 HEMI kit has everything in one kit, including a 92 MM cable driven throttle body. It's not any less expensive to not get the throttle body. It just comes with the kit and has the TPS and IAC built in anyway. The XIM ignition controller reads the stock sensors to create the signals the ECU needs. It also generates a clean tach signal on it's own. The kit is $2950
