Fast Ez-Efi??

Hi guys,

I have been following the progress of EZ EFI, and Powerjection since May, so I have a few observations that I can offer.

The EZ system has the injectors below the butterflies, and from what I've researched, this can cause difficulty in getting a smooth idle in some instances. EZ isn't able to be tuned from a laptop either, and won't contol ignition timing.

Powerjection can be tuned from a laptop, so when you get more experienced you can modify the tune more than the hand controller will afford. Injectors are above the butterflies too. A new model was due in March which had control of timing, but now has been put off indefinitely (according to a rep from their technical dept).

Holley has a new TBI system called Avenger EFI. It has a hand controller and laptop tuneability. It can also control timing with the use of a GM HEI a pin module. It's the only one that, so far, I can't find any negative reports on.

Cheers,

Robert
