Installed FAST EZ EFI ON THE RT

[snagm z]

HOLY SHIT WHAT A DIFFERENCE!

I originally had a 800cfm carb. and was disappointed in my results. So i switched. I have a base line Dyno with the carb and scheduled next Thurs to dyno & tune it up  the efi. i can already tell i have significant gains. will scan and post my results with my engine build blueprint.

What engine combo do you have below that new Fast EZ EFI  ....

[1970Moparmann]

Need to hear more about this.    Do tell.....

[jb666]

You'll LOVE it.. The simple things.. Like reaching in, after your car has sat for two weeks, tapping the key and having it fire right up while your feet are both outside the car... Now THAT'S cool...   Throttle response..... Reliability..

Is this set up on your Procharged combo  , just curious... the founder of Fast EFI, lives some were near here, I think up the hill in Twain Harte, Ca., I think it was "Dan" Orange Hemi RR fame "68X426" who told me that...

Mine? No. I'm not running the EZ system..  I'm running the XFI 2.0 system. My setup was a PITA to get tuned, but once it was dialed in correctly it's been a DREAM!!!!!!

JB....I just ordered the XFI 2.0 system as well. I will be installing it this weekend.  What problems did you have?  I hear there is a lttle more tuning involved than with the EZ setup.  What laptop are you using....questions man and I need answers!!!!

Problems... Just minor tuning tweaks that we messed with most of the summer. Adjusting throttle blades. TP Sensor. Temp vs idle adjustments. Fans.

The usual... like I said, once it was dialed in, it's incredible. The car runs like an absolute DREAM now...  So many think they can just throw it in, do a quick tune and you're set.. That couldn't be farther from the truth.. But, it's worth it in the end!!

Laptop? I'm running the XFI software on a spare Dell I had. The system stays in the car at all times (I've had to make adjustments on the road more often then not). I really like the ease of adjustment(s) though.. they definitely made it easy.
The 2.0 is an improvement though... Takes a LOT of the guess work (and manual tuning) out of the equation.

thinking about going to EFi also at some stage ,

Thanks, I was just curious more than anything, fuel mapping those things can be a major hassle sometimes, I end up have an old buddy do it for me, he owes me a couple still...LOL.. he's extremely hard to get to do anything & usually won't, but when he does, he the shit...

Jon set all of that up for me. I wasn't about to pretend I was smart enough to do something that could actually cause major damage to my motor. I have no problem with the fine tuning..

Do you have to have the lap top to run the system  or is it just for the fine tuning convenience

A lap top is used for the tune. My plug runs out of the glove box. When I'm done I coil it back up and shut the glove box door. You'd never know, from the inside of my car, that the whole underside of the dash (one side) is a computer... 

I suppose you could have someone else tune it with their laptop as long as you'd never need to adjust anything yourself you'd be fine.. But yes, you must plug in to make any changes.

Thanks, it sounds like a very cool system in your Charger... I was just curious, never too old to learn...

Sweet, I'd like to hear more too. Right now I got the ez efi sittin in my garage waiting for my car

I'd go for that!  Can't complain about reliability so far but the carb would not be missed.

Any change at all in fuel mileage?  Not that I'd get my money out of it anytime soon, asking more out of curiosity.

We have been successful with it so far.  All I can say is we put it through its paces at the OUSCI and it was amazing.

[Vainglory, Esq.]

Awesome.  My next major upgrade is probably the EFI.  Then again, I have a lot of minor upgrades to do first.

[J-440]

  Been studying up on EFI and the only thing that concerns me are the VE tables and zones.  Does FAST have a pre-programmed setup similar to your car and all you have to do is input your engine specs into the pre-programmed setup?  From the pics on the website, everything is pretty much plug and play.  Can't wait to play with it.

jb666 when are you going to the dino?  Do you already have thread to your motor combo details, if so where?

That is correct if you go with the EZ-EFI.  You go through a set up that asks for cubic inches and other parameters and it has a self-learning ECU that fills in the gaps.  You tell it (3) target AFR's for idle, cruise and WOT and it does the rest in between.  Its pretty slick although you still need to understand what your engine wants.  Most people think because its EFI they can just lean it out and everything is great.  That does not work, the motor still wants what it wants.  The good thing is you can lean and fatten up for different conditions like a day a the track or just cruisin.  I do it all the time.  Sometimes when I am cruising down the highway I will reach down and lean it out a few clicks for fuel savings and fatten it back up when I get into town.  All done with handheld unit in the car on the fly.

After competing at the OUSCI and only seeing a few carbs, they are slowly becoming a thing of the past sorry to say.  BTW- this system comes in a Multiport EZ setup which, I think, would be ideal if want to take it to another level.
