Sorry I forgot both of you were Greg's ,Yes thats what I meant.

I didn't ask - but since he knows what it's running on -- a big block with 8 stacks -- I would ASSume it works just fine. The harness would be for 8 injectors... The EZ EFI has to be BOUGHT as a "multipoint" system - or it's built to run their throttle body. They have three or so set ups for the EZ EFI system
and it asks you in "set up" how many injectors and their flow rate and the pressure etc.

The XFI is a sequential system using the cam signal. The EZ EFI is a batch fired system using a standard distributor and using a tach signal input. I would again ASSume since this is a firmware upgrade that they have factored in that it would control the timing and use the cam signal.

I think you won't find much info on it yet - because it's not available yet!

I told my buddy that what I'd do is SELL the XFI unit and harness and buy a EZ EFI and it's proper harness... the XFI used is probably worth more than the NEW EZ EFI. The pricing on the EZ system when you're just buying the ECU and harness is pretty reasonable.

has anyone called FAST for an update ? I forgot last week.

Not me, if I think of it tomorrow I'll try to call.

I finnally got intouch with Fast about the release date on the XFI 2.0 download. They have no hard release date yet, but figure it is still one to two months away.

I am doing some of the Beta testing for the 2.0 XFI for FAST. There are a bunch of cool new features that work great so far. We are still in the beta testing stage so looking for any little bugs before you guys get it.

It will auto tune like the EZ EFI, it is more complicated then just plugging in a few parameters like the EZ EFI though. So far it does a real good job on the part throttle driving auto tune.

Greg said XFI is sequential and needs a cam sync... it does not. It can be run in bank to bank like the EZ EFI also if you wish.

The price is going to be $50 or if you purchased your XFI in the last year it will be a free upgrade. $100 if you want to send in your ECU for the 2.0 cover.

It is something you can do yourself by using the flash update wire and the cal file we can send you.

Thanks for the update Brian ! :cheers:

I just got an e-mail from FAST that says the new programming is available.
upgrade

The software only upgrade is $49.95 and the ecu & software upgrade is $99.95.

I'll be calling next week to get an RMA :woot:

If someone is considering this option, I have just posted up my FAST XFI + XIM + harnesses for sale...

FS: FAST XFI and XIM modules plus LS2 harnesses

I just sent my XFI to FAST for the update and new box. I know it will be back before I'm ready for it.
